Infrared Zoo

If you are looking for a way to find some science fun on the computer this week, try this link to the Infrared Zoo at http://coolcosmos.ipac.caltech.edu/image_galleries/ir_zoo/. It is a gallery of infrared images of various animals. I particularly like the Hide and Seek Game, because it gives more details about each image (just click on an image once it appears).

Looking at the images made me think about cold-blooded versus warm-blooded animals. I was surprised to see the cat had warm feet, because I always thought an animal’s extremities were the coolest parts. Of course, the extremities give off the most heat when the animal is too hot.

Have fun exploring this site!

Clouds

We are feeling in a lazy, summer mood this week, so we’re going to do some cloud watching. Grab a blanket, find a quiet place in the shade outside and look up at the clouds.

The weather has been in the news a lot lately. With practice, you can tell something about what the weather is going to do by checking the clouds. Most of us recognize there are different types of clouds, some puffy, some wispy and some that seem to cover the sky in an endless blanket. If you and your children get interested in learning the types, there are many good books with pictures and even cloud chart posters available to help you learn their names.

Are any of the clouds darker than others? Those probably contain a lot of water. Puffy clouds that begin to tower up, raising high into the sky might indicate a thunderstorm is building. Drab gray clouds that cover the sky suggest a gentle rain that is going to settle in all day.

If your child is ready, you can discuss what a cloud is made of and how the water cycle works. Ask them how they think rain forms. We once made simple stick puppets of a mountain stream, an ocean, trees and water with wavy lines representing evaporation, clouds, and funny rain drops with cat and dog faces on them (“raining cats and dogs”). Then we did stories incorporating ideas of the water cycle, but in a way that was gently humorous, such as the rain drops didn’t want to leave the clouds, and the clouds had to shake them out. We still have the puppets, and do the show every once in awhile. Repetition is good for learning, and the children don’t even know they are learning when something is fun.

What are clouds made of? Clouds are made up of more than water. In addition to bits of dust, micro-critters such as bacteria, fungi and algae get caught up in clouds.

But hey, it’s a lazy summer day, so don’t work too hard. Hum, that cloud looks just like a mattress, and mattresses are for sleeping. ZZZZZZZ….

Bird Watching

One of our favorite things to do is bird watch. These lively creatures are interesting because they are colorful, active and can be found almost anywhere. We can hear them sing and chirp. This time of year birds are migrating, building nests and raising babies. There is a lot of excitement in the bird world.

You can simply look out the window and spot birds. Take a few minutes to see what kind it is and what it is doing. We learned our birds by figuring out a few at a time. We keep a notebook full of drawings and notes next to our favorite birding window. Each year we’ve had regulars who we recognize and also new birds. Last year we had house finch males with yellow on their heads instead of the more typical red or orange. This winter we had juncos for the first time.

What can you do to encourage birds? Many people start by making simple bird feeders, such as the classic peanut butter on a pinecone rolled in birdseed. You can make another simple feeder by stringing fruit such as raisins, grapes, cherries or orange sections on a bit of twine or string and hanging it out. Just be careful because scattering food for birds can also attract unwanted guests, including bears in some areas! We have problems with roof rats so we only feed thistle seed. Niger thistle seed attracts colorful birds like finches and doves, but not pigeons or rats. Check with your local Audubon Society for recommendations.

Making cards full of nesting materials can be a fun project that is easy to do with supplies from around the house. Gather index cards or three-inch by five-inch card stock, yarn, thread, hair, or anything else you think a bird might use in its nest. Brainstorm about what might be useful to a bird. Poke holes in the index cards (enough for all participants) with a hole punch or nail (with an adult’s help). Tie a 12-inch piece of string, yarn or ribbon through one hole to serve as a hanger. Loosely stuff the rest of the holes with a variety of nest making supplies, making sure the birds can pull it out fairly easily. When you are finished, go outside and hang the cards in bushes or trees where the birds will find the materials. Check over time to see which materials they chose first, second, etc. Refill the cards as needed.

These supplies are actually useful to birds. We once had a bird fly away with the end of a kite string, spreading the string throughout the neighborhood as it unwound from the spool.

If you get serious about birding, you might think about planting a bird garden. Find out abut which native plants in your area provide food or shelter for birds and add a few to your garden. Providing water through a birdbath or pond is also helpful as long as the water is kept clean and fresh. Check for more information in books, magazines and on the Internet.

Finally, even if it is raining and nothing is happening outdoors, ask your child what it would be like to fly like a bird. Then pretend you are birds. Spread your wings and soar and swoop together.

Happy flying!
