Exercise your science muscles! Look around you; notice some of the many things that relate to science. Can you find something that is made from chemicals? What kinds of chemicals? Why those chemicals? Can you find something that is not made of chemicals? We like to think about the science and mathematics behind everyday objects and experiences. Can you find something that does not relate to math?

## Squishy Circuits

The museum educators taught an electric circuits program experimenting with Squishy Circuits. We used two different formulas of flour dough, one conducting, the other insulating, to create electronic circuits. We learned a lot, and you can too if you follow the link. Squishy Circuits became the heart of our winter 2012-2013 program about electricity, conductors and insulators.

## Sweet Surface Area

Science is all around us, so why not have some delicious fun while we do it? The process of making a root beer float (PDF) is simple but it involves some pretty sophisticated scientific concepts. Carbonation, surface area, viscosity, and temperature all play a roll in creating a treat that is up to your personal highest standards.

## Pi Day

Pi is the ratio of the circumference of a circle to its diameter. While it has been calculated to trillions of digits, pi starts 3.14159. . . and in honor of this number, many people celebrate March 14 (3/14) as Pi Day. Although we are not formally observing the date this year, we have put together a few pi facts to help you think about this remarkable number.

Look at this! » This is our educators' take on Pi, but there are many ways to think of this number. Some people are even campaigning to replace Pi Day with Tau Day, June 28.

## Household magnets

Chances are very good that you have experimented with magnets. People have been fascinated with magnetism for thousands of years.  As familiar to us as they may be, magnets still have some surprises for us. Here is a small collection of some of our favorite magnet experiments.

## Fascinating fluids

Fluids are amazing. Fluids flow. Liquids have variable shapes but almost constant volumes. Gases take the shape of their containers and can be squeezed and stretched relatively easily. We are made of fluids, mostly water, arguably the most interesting compound in the universe.

What is fine sand? It is a solid, but it can behave like a liquid, flowing yet maintaining its volume. What is Jellotm? It is certainly not a solid! Smoke has solids in it, but it is not solid either.  Then there is the seriously weird world of superfluid helium. Liquid helium a few degrees above absolute zero can climb out of its cup, leak through molecule size pores in materials, and if swirled, can continue to revolve forever.
