Learning about electricity is made fun and creative when squishy circuits are used! Insulated and conductive "dough" which you make in our own kitchen combined with colored lights, beepers, batteries, wires, small motors, and propellers make learning fun. Check out the web site for squishy circuits and look on You Tube for videos of projects. You and your child will enjoy working together on these projects. A beginning kit with the main parts you will need to get started is available on the squishy circuit website...look for the squishy circuit store. Enjoy!
.
The squishy circuits projects have been developed by the University of St.
Thomas School of Engineering, The University of St. Thomas Young
Scholars Program, and the 3M Foundation. Be sure to check this out
for lots of fun and learning. Students love this lesson, and have
asked for it to be repeated.

First grader searched to solve a mystery during a recent Science Granny’s visit. The children found that if they dissect an owl pellet they can find out what the owl has been eating. As you may know (and your child knows), owls eat their prey whole or in large chunks, with fur, bones, and all. “After swallowing whole prey, the bird’s body breaks down food to absorb nutrients and form a pellet from wastes. Several hours later, the bird expels the pellet through its mouth.”1 (Yes, they cough up a ball of fur and bones). The first grade scientists used toothpicks, tweezers, and magnifying glasses to find the bones, fur, and other indigestible remains of an owl’s dinner so they could figure out what it told about the food that the owl had eaten. By the way, the owl pellets were commercially purchased and sterilized.
If you want to get a small book on owls which includes a sterilized owl pellet and bone sorting dish, I recommend the following book:
Hammerslough, J. (2004). Owl Puke. New York: Workman Publishing Company.
Cost is about $11. This could make a very educational gift.
Look further on this site for information on a loupe, a special magnifier which the children use when they study their owl pellets. (Look for the section on Christmas gifts.)
