Weekend Nature Challenge: Rock Hunting

by Melissa Harding

DSCN2415A rock makes an excellent puppy.
They’re practically almost the same.
Except that a puppy’s rambunctious;
a rock is a little more tame.

It’s true that a rock’s not as hyper.
It may not chase after a ball.
And, often as not, when you call it,
it won’t even hear you at all.

And maybe it doesn’t roll over,
and isn’t excited to play, but
rocks always sit when you tell them,
and rocks really know how to stay.

So go ask your folks for a puppy,
and possibly that’s what you’ll get.
But, still, if you can’t have a puppy,
a rock is a pretty good pet.

It doesn’t annoy you with barking;
it quietly sits on a shelf.
A rock makes an excellent puppy.
That’s what I keep telling myself.
- excerpted from a poem by Ken Nesbitt

If there is one thing in nature that is often overlooked, it is the humble rock. The job of a rock isn’t glamorous; it erodes over time, slowly adding minerals to the soil to help plants grow. It provides a home for slithering and crawling critters, acts as a sunbathing station for lizards, and provides a launching pad for moss and lichen. However, even though rocks aren’t glamorous, they are very important; without them, we would have no soil, no plants, no life. That’s why you can find rocks just about anywhere! This weekend, we challenge you and your family to scour your neighborhood for rocks. Not just any old rocks, but special ones that speak to you. Children love finding treasure and will jump at the challenge of looking for shiny rocks, sparkly rocks, small rocks, big rocks, red rocks or black rocks. Take a walk around your neighborhood together and collect your top two rocks to take home; they make good garden sentinels, animal habitats and maybe even good pets.

Take the next few days to explore your neighborhood and go rock hunting with your child. What colors, shapes or patterns did you discover? Did you see anything else of note? Tell us in the comments below.

Home Connections: Raising Butterflies Indoors

by Melissa Harding

Phipps Science Education_ Butterflies (1)You may have noticed that the butterflies are back for the summer. Cabbage whites are fluttering around your broccoli, looking to lay some eggs, and tiger swallowtails are looking for nectar in your flower beds. Butterflies are out of hibernation and looking for a good time. Adult butterflies spend their days doing two things – drinking nectar and laying eggs. These eggs are the start of the butterfly life cycle, which is both exciting and easy for even young children to understand. Beyond that, the life cycle has an air of mystery about it: What is really happening in that chrysalis? How does the butterfly get in there? While it is very enjoyable to watch them flutter around your backyard and to look for eggs and caterpillars on your plants, it can be even more fun to raise butterflies indoors. This is a great way to practice scientific thinking; your child will learn about the butterfly life cycle while utilizing his deductive and observation skills – and have a good time doing it!

To begin with, you will need some caterpillars. There are multiple online resources that provide you with both caterpillars and a butterfly habitat. It is best to purchase a butterfly species that is native to your area so that you can release them after you are done. Each kit come with care instructions to help you give your caterpillars a comfortable experience. Make sure to follow the directions regarding feeding and when to put your chrysalids in the larger butterfly habitat. You will also need magnifying glasses, a nature journal and any butterfly resources that may help your child learn more about butterflies. (See the bottom of this post for resource ideas).
hghhg

Learn about Larvae
Begin your butterfly experiment by observing the caterpillars; set aside a set time each day to observe your critters together with your child. Caterpillars have interesting bodies; they have both “true” legs and little suction cups called “pro legs”. They also have an assortment of spines and patterns to confuse their predators. Take some time and observe your new friends. What colors are they? What end is the head and what end is the tail? Encourage your child to use his magnifying glass and learn about caterpillar anatomy. Caterpillars also engage in some pretty weird behaviors. Watch them walk upside-down on plant stems and use their jaws to gnaw away at leaves. The caterpillars you receive should go through several stages of molting, so see if you can catch them in the act! There are many exciting behaviors that your child can observe and record. Some of these  are so strange that it may prompt your child to start asking questions; this is a good time to give them resources to help fill the gaps in their knowledge, while encouraging them to wait and see if they can discern the answers by further watching.

Chrysalis Count-down
One of the most mysterious parts of the butterfly life cycle is the pupa stage, or the chrysalis. Before your caterpillar molts for the last time, it will hang in a “J” shape off one of the branches in its container. This is a great time to keep an eye on your caterpillar, as you may be lucky enough to watch it shed its skin and turn into a pupa. The skin that makes up the chrysalis is very different from the skin of the larva; it may be a completely different color. Often, this is to camouflage the vulnerable pupa from predators. Once your caterpillar is in the chrysalis, create a chart in your journal to count down the days until it emerges. It can often take up to two weeks for this to happen and there is very little else to observe during this time, so counting down the days is a fun way to keep your child engaged in the process.

butterfly phipps unplugged technology petruskaBeautiful Butterflies
Soon you will notice the chrysalis begin to shake. This is caused by the butterfly inside wiggling its way out! If you can catch this in action, it is an incredibly exciting sight. The butterfly will emerge slowly, covered in a sticky, red liquid; this is meconium, the remnants of the metamorphosis process. For the next several hours, the butterfly will flap its wings to dry them and fill them with blood. This is a very vulnerable time in the life of a butterfly; it is unable to fly until the wings are dry. Make sure to have a source of nectar in the habitat for your hungry butterfly to drink once it is ready. Have your child record this process if they are able. This is a rare opportunity for your child to get incredibly close to a butterfly; observe it carefully, maybe even drawing or painting it. Watch it unfurl its proboscis to drink nectar and use its antennae to smell. Count its legs and talk about the qualities of an insect. What an exciting time to observe!

Time to Fly
When you are done observing, it is time to release the butterflies. They will not be happy in their habitat for very long, nor will they be able to complete the butterfly life cycle without a mate. Releasing your butterflies can be a special occasion; reading a poem, sharing observations or even going to a special spot that you think the butterflies will like are all lovely ways to celebrate the life cycle. Slowly open the habitat and gently shoo the butterflies out into the open; they may falter a bit at first, but will quickly find their wings and soar away to find food and mates.

Here are some resources to help you get started on your butterfly raising journey:
Live caterpillars:
InsectLore and Carolina Biologicals are reputable places to get started; you can find a kit to match any price point. Try to purchase your caterpillars from a site that sells them for education, as opposed to weddings or events.
Taking care of your critters: This resource will give you details on how best to raise your new friends.
Butterfly gardening: Make your yard friendlier to all pollinators with these tips.
Monarch tagging: Monarch Watch is a citizen science program that helps scientists to track the migration movements of monarchs.

Watching this process gives children a sense of the complexity of the life cycle and makes them feel like they have been a part of helping their caterpillars to grow. A wonderful activity, growing butterflies can connect children to nature on multiple levels; if it peaked your child’s interest in butterflies, spend some time observing the ones that visit your yard. You can also go to your local botanical garden or children’s museum; these informal learning institutions often have pollinator gardens to attract butterflies of all kinds. Some even have butterfly rooms, like at Phipps, where butterflies are cultivated in large numbers. If your child’s interest in butterflies continues over the summer, consider raising another species of butterfly at home or taking part in a monarch tagging program at your local nature center. The sky is the limit!

What is the Role of Art in Science Education?

by Melissa Harding

OLYMPUS DIGITAL CAMERA

“The difference between science and the arts is not that they are different sides of the same coin… or even different parts of the same continuum, but rather, they are manifestations of the same thing. The arts and sciences are avatars of human creativity.”
- Mae Jemison; doctor, dancer and first African American woman in space

What inspires people to choose a science-based career? What inspires those scientists to make great discoveries and innovations in their fields? There is a growing body of research that suggests that creativity may be the answer. Creative thought is crucial to innovation; moments of insight require creativity to create bridges between ideas and make clear links that were hidden to the thinker.  In a series of discussions with scientists at the Eurpoean Molecular Biology Laboratory (EMBL), an international research institute in Geneva, Switzerland, researchers found that the institute’s many scientific leaders ascribed three qualities to the making of a good scientist: rigorous intellect, the ability to get the job done and the ability to have creative ideas. They all emphasized the synthetic nature of creativity – it brings together previously unrelated thoughts to create something new and exciting. To quote one respondent: “Creative scientists have the ability to step back from what’s happening in the lab and look at the big picture and put things in perspective”. They are also unafraid of tackling something new, while still having the humility to understand how little they know.

If creativity is so important for the creation of good scientists, then it only makes sense to nurture this trait in students. One way to do this is through multidisciplinary education, combining art with science. As has been shown through teaching science and literacy together, merging two separate subjects can have big results. In 2008, the DANA Arts and Cognition Consortium, a philanthropic organization that supports brain research, assembled scientists from seven different universities to study whether the arts affect other areas of learning. Several studies from the report correlated training in the arts with improvements in math and reading scores, while others showed that arts boost attention, cognition, working memory, and reading fluency (Source). Need more proof? A recent study found that Nobel Laureates are more likely to pursue artistic hobbies and endeavors than the average scientist. A separate review found that, out of twenty featured scientists, those who engaged in artistic past-times tended to publish high-impact, highly cited research. Even Scientific American is touting the change from STEM to STEAM. Clearly, art is important in science education.

OLYMPUS DIGITAL CAMERA

In fact, art is not so different from science – at least in practice. Both art and science are driven by the need to interpret the human experience, whether by painting a flower or dissecting it to understand its inner mechanisms. Additionally, both art and science require good observation and deduction skills. To quote Albert Einstein, “The greatest scientists are artists as well.” He believed that his innovations came from creative intuition, just like those of an artist. Art is also a way to inspire curiosity and wonder. Some students may not be initially interested in science, but can be lead to methods of scientific thinking through art projects that directly relate to science topics.

One reason that this approach is so effective in engaging students is that it addresses the whole child. Children are naturally creative and artistic; they are good at finding new solutions and thinking outside the box. Bolstering students’ creativity by default also increases their critical thinking skills, problem solving abilities and collaborative spirits. Children like art and find the free expression of painting, sculpting and drawing to be fun and liberating. By pairing this natural love of art with science, you are truly creating an engaged and excited child. At Phipps, we try to combine science concepts with photography, art and the sensory experience of horticulture to get students curious and connected to the natural world. While some students that come through our doors are plant lovers, many more come for the art and stay for the science. Art also helps children to feel emotionally connected to the world around them, which research also shows is what creates future naturalists.

OLYMPUS DIGITAL CAMERA

However, the arts are also worthwhile for their own sake. Without both artists and scientists, the world would be a very dull place indeed. The way that art interprets the world is very different from science, but equally relevant to the human experience. We still need a future generation of musicians, artists and photographers. The same curiosity and drive that make a person a scientist also make a person an artist; both scientists and artists have the skills needed to become successful adults.

An easy way to encourage artistic expression is by spending time outside, which naturally promotes both art and science together. Not only is the natural world rich in beauty, but it is also rich in complexity; both are interesting lenses with which to see the world.  Additionally, try integrating some of these practices into your play and family time: dance, photography, poetry writing, creative writing, nature journaling, music playing and appreciation, painting, drawing, sculpting, gardening, and nature crafts. Making up dances together as a family, taking photos on a hike or planning a colorful garden are all easy ways to engage your child in both art and science.  These activities also engage your child in the natural world, creating a life-long connection that will serve him well emotionally and intellectually for years to come.

Get Engaged in Science: Send a Poem into Space with NASA

by Melissa Harding

mars

hghghg

The NASA Starshine project, launched in 1999, consisted of three, optimally reflective spherical satellites designed by the U.S. Naval Research Laboratory. What was unique about Starshine was that these three satellites were built, not by NASA itself, but by a volunteer coalition of organization and individuals in the USA and Canada. Covered in approximately 1000 small, front-surface aluminum mirrors, these orbs were deployed into highly inclined low Earth orbits as a service to the international education community. As the satellites traveled, their reflective mirrors made them visible to students all over the world, who observed their movements as an interactive way to learn math and science. To help students make a personal connection to the project, NASA sent mirrors to schools where they were polished by students. I was one of those students. Even though it was over a decade ago, I still remember that experience and how excited I was to be a part of history.

A generation of students later, NASA has come up with another way for the public to interact with its space missions. This time, they are sending a rover to Mars to study its upper atmosphere.  Called the Mars Atmosphere and Volatile Evolution (MAVEN) project, this mission will examine why Mars lost its atmosphere, and how that affected the planet’s water supply. To make this more relevent to the public, the mission team at NASA is calling for literary submissions – haiku, to be specific. Three of the best haiku will be included on a DVD that will go with the mission to Mars. While this may sound a little silly, it is actually a wonderful way for NASA to engage the public in its latest mission to Mars. By contributing a poem, a participant is making a personal connection to space exploration and the study of the solar system (and beyond!).

If you would like to be a part of history yourself, all citizens of Earth are invited to participate! Check out the MAVEN homepage to get started. NPR has also gotten in on the game; you can read the original article and submit your entry at their website as well. The submission deadline is July 1, and starting July 15, the public will vote on the three winning poems to travel on the spacecraft’s DVD. The winners will be announced Aug. 8. The poems will be accompanied on the MAVEN by some student artwork, selected by popular vote in a separate contest.

Note: You do have to be 18 years old to create a log-in email profile, and children are encouraged to ask parents and teachers for help. All haiku must be in English.

This is a great project for families and teachers alike. Not only will participating get your child excited about NASA, but it may create a spark that lights the fires of a future career in science or love of space and nature. Even if your submission is not chosen, the names of every participant will be carried up to space. What a great incentive!

If your child or students enjoy this activity, check out some of our others suggestions for incorporating more poetry into your family or student life.

Backyard Connections: Who Lives in Your Yard?

by Melissa Harding

nest

This new series, Backyard Connections, gives fun and easy tips for exploring the nature right outside your door.

Spring is one of the best times for nature observation; it has the benefits of winter, like bare trees and open ground, but is bustling with growing things and new life everywhere. These few weeks in the middle of spring are some of easiest times to really see what and who is living in your yard; even urban yards can be full of more life than you realize. This is important to understand; the animals that visit your yard make up a large part of your backyard community and are affected by any changes you may make to it. Sometimes the unsightly features that you wish to remove from your yard, like a brush pile in the back or a misshapen shrub, are really vital to critters that need them. In addition, it can be useful to understand who is nibbling off the tops of your pea plants or digging up your wildflower seeds; once you know who is doing the damage, you can take measures to gently redirect these backyard vandals to more desirable options. Finally and most importantly, backyard creatures like rabbits and birds are accessible to children; it can be fun to learn about animal life cycles through observation over time, such as watching a litter of baby squirrels grow up and raise their own young. Children grow invested in the lives of these critters and truly think of them as garden friends, all while growing in their observation and deduction skills.

How can you figure out who is living in your yard? Observation, of course. Keeping a journal of animal signs can help you and your child learn more about the critters in your yard over time. You can track feeding habits, nesting times, and more. Remember, it is never wise to poke at or get too close to any animal or its home. Observation from afar is the best way to learn about these creatures.

Look for the following signs of animal life in your yard:

rabbitWhere do I live?
Bare trees are the animal watcher’s best friend. By the end of April, most flowering trees are still sparsely covered and many large shade trees have only minimal leaves. In addition, many migrating bird species that spend their winters in the tropics are back for the summer. Backyard favorites like catbirds, hummingbirds, orioles, and a whole host of warblers are looking for places to nest, eat and sing! One way to know who is living in your yard is to look for nests; every bird species builds differently shaped nests in different kinds of locations. All of these can be found by scanning the bushes with your naked eye or a pair of binoculars. Another way that you can keep tabs on nesting birds is by providing bird houses for them; bluebirds, wrens and other small birds that are susceptible to nest predation appreciate this consideration and will often reward you by inhabiting these structures. If you look carefully, you may also find nests that have been abandoned by birds and co-opted by mice or chipmunks; ever opportunists, these small critters use old nests to raise young and stay warm in the winter.

Birds are not the only animals that build nests. Squirrels also build nests in trees, commonly called “dreys”. They often look like large, leafy clumps situated in the crook of several tree limbs; often located very high in trees, some dreys are so large that they can be seen from fairly far away. Since a typical grey squirrel can have up to three or four litters a year, this is an important place for them to raise their young.

There are also many animal homes to be found on the ground. Look under rocks and fallen logs for reptiles and amphibians; small invertebrates also like the constant temperature and moisture of life against the ground. A brush pile is a great place to find many small mammals and even some birds; low shrubs provide shelter and sometimes food. Your yard may also be home to larger animals that build dens underground, like rabbits, groundhogs or even foxes. Look for holes in the ground near shrubs, trees or other sources of cover.

What do I eat?Phipps Science Education 64
The easiest, and sometimes most frustrating, of animal signs to spot is evidence of eating. Whether this means shells around the bird feeder or a decimated garden, most backyard animals are not shy about making your yard their salad bar. Half eaten leaves and broken stems are a sure sign of animal feasting. If you find something unusual, like peanut shells buried in your garden beds, investigate further and figure out which backyard critter is responsible. This is a great way to hone your child’s deductive skills; make an educated guess and then set up an experiment to learn more. You’d be surprised how excited your child will be to check the same spot every day for updated activity.

You may also find evidence on a smaller scale, such as with caterpillars and other herbivorous invertebrates. Introducing lady bugs or other predator insects into your yard can be both effective and fun to do with your child. Another great way to help with insect issues is to provide a toad home, which can be as simple as an upside-down flower-pot nestled in the shade; a toad home is both wonderful for your garden and an easy way to learn about amphibians. You and your child can visit your garden friend by lifting up the pot on occasion and can even watch them raise young over the course of the summer. Toads will return to the same place every spring, so you will have a friend for life!

Phipps Science Education_parents (3)How do I move?
Many backyard critters show their presence through tracks. Especially in the spring, when the ground is soft and muddy, it can be easy to see exactly what your resident rabbit or raccoon has been up to based on where its tracks lead. Most of these animals leave fairly distinctive tracks, from the two hooves of a deer to the hand print of a possum. Look for tracks in newly dug garden beds, areas with sparse plant cover and muddy places. If you can’t make out a clean print, the overall pattern of the tracks can help you figure it out – clusters of four prints indicate a galloper, like a chipmunk, whereas a wider, heavier set of tracks indicates a more meandering animal, like a bear or raccoon.

Another kind of animal track is evidence left by their movement, like a spot of matted plants where an animal has been resting or a bare spot on a tree where an animal was rubbing. Look for signs in your garden beds and under trees where your backyard friends have been busy. While you are looking, keep your eye out for other signs like feathers, clumps of fur or snake skins. All of these signs can help you figure out which animals are using your yard as a home and even what parts they are relying on for food and shelter. Take a magnifying glass outside and go on a track hike, looking close to the ground for signs of life. Record your observations and see if track patterns change over time!

To make the most of watching animals in your yard and help them thrive:
1. Help your nest-making backyard friends by providing nest helpers  and bird and squirrel feeders out of natural materials (via The Crafty Crow)
2.
Get involved in citizen science through Project Feeder Watch, NestWatch or Celebrate Urban Birds
3. Learn more about birdwatching from the Cornell Lab of Ornithology’s online resources; identify feathers using the US Fish and Wildlife’s Feather Atlas or try this great inquiry activity  (via Nature Skills).
4. Learn about specific animals tracks (via Minnesota DNR) or find a similar guide to match your particular region.
5. Provide a brush pile in the corner of your yard; many birds and small mammals will appreciate the shelter it creates; similarly, a rock pile in a sunny spot can provide a great home for garter snakes and other small reptiles.
6. Provide a water source near a protective shrub or tree; all the animals in your yard will appreciate this, especially as it gets hotter through the summer.
7.  Attract toads to your yard (via Bird and Blooms) and learn more about reptiles and amphibians in your area.

These are just a few of the things that you will find in your yard if you look for them; animals, including insects, leave many different signs – including themselves! As you and your child spend more time learning about the animals that live in your yard, you will come to be experts at spotting them. You may also come to appreciate them as an integral part of the ecosystem of your neighborhood. Remember, both you and your backyard are part of the same community of life!

Repurpose Your Trash: High School Challenge #6 of the Fairchild Challenge at Phipps

by Melissa Harding

During the latest challenge of the Fairchild Challenge at Phipps, participants were asked to fight against landfill waste by finding a new use for something that would otherwise be discarded. They were to create a prototype of a consumer product that is made entirely of household, school or other commonly found trash. They were also asked to describe what their item was, what it was made from and how it could be used. In total, 67 students participated in this challenge; they submitted purses, chairs, rugs, bird feeders and even a speaker system for an iPhone. All the entries were creative and well-designed; some of which are sure to have a future on the store shelf!

The first place entry, submitted by students from Moon Area High School, was a tiled mirror made of scrap plywood, pieces of glass bottle, and plastic cups.

101_3229

The second place entry, submitted by Moon Area High School, was a purse made of fused plastic bags.

101_3227

The third place entry, submitted by Gateway High School, was a iPhone amplifier system made of a toilet paper tube and plastic drinking cups.

101_3223

Honorable Mention, submitted by North Allegheny High School, was a rug woven out of plastic bags.

101_3232

Each of these winning entries was crafted to be sturdy, useful and even attractive. Though only a few of the entries could win, all the participants are winners for finding new and creative uses for discarded materials! By reconsidering our resource uses, together we can create a more sustainable future.

If you would like to learn more about how our department repurposes discarded materials in our programming, check out our April Home Connections series on cardboard, plastic and glass.

Little Sprouts: We Heart Veggies

by Melissa Harding

April_18_13_camp_19

Spring is the time for planting gardens; peas, carrots and other cool weather crops are already shooting out of the ground and getting ready to produce delicious vegetables to fill our plates. Our Little Sprouts are especially excited to spring; in the latest Little Sprouts: Single, We Heart Veggies, campers explored our edible gardens in search of seasonal produce. They learned the parts of a plant and which of their favorite veggies are really roots, shoots, leaves or fruit.

To begin, campers used vegetables of all different shapes and sizes to make paint-stamped pictures of salad in a bowl. They used lettuce, broccoli, carrots, potatoes and celery to create different textures and colors in their “salads”. After they were finished, campers had time to play in our new sensory bins filled with seeds and sand; they used recycled containers, measuring cups and funnels to explore the items inside each bin.

April_18_13_camp_16

During the lesson, campers learned that plants all have the same parts – roots under the ground, stems to carry water, leaves to make food and flowers and fruit to create seeds. They learned that some veggies, like celery, are stems and others, like carrots, are roots. Campers then made some imaginary vegetable soup; each camper stirred as we added vegetables of different colors to the pot and sang a vegetable song. Finally, we read Stone Soup and talked about the importance of sharing our veggies with others.

After all this learning, campers were ready to explore. They traveled to the outdoor edible garden, where they pulled onions and carrots out of the ground to explore their roots and smelled the fragrant leaves of several different herbs. Some brave campers even tasted a kale leaf! After returning from their tour, campers planted their own broccoli plant to take home and grow outside. Soon, they will all be eating veggies of their very own!
