Any time you build something or take something apart, you are actually doing things that engineers do. You can build with many different materials, from blocks to straws and marshmallows. This process involves thinking about what you want to build first and then designing a structure that achieves your goals. After you spend some time designing different things, you might even figure out how to build an elevator that moves up and down.
In these interactives, use your hands, feet, eyes, ears, brain, imagination and cool tools to experiment, design, test and discover amazing things about the world around you. It's science and it's fun!
Sunprints encourage an interest in the photographic process using only sun, water, and a bit of imagination. Place a fern, flower, or other object on the special paper and set it in the sun briefly. Then rinse the paper in water and watch as a beautiful long-lasting image appears!
