Visitors add drops of copper sulfate solution onto a steel nail. They observe the nail change color from silver to brown as the copper plates onto the nail.

Visitors prepare six solutions combining vinegar and ammonia that range incrementally from acid (all vinegar) to base (all ammonia).

In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.

In this activity, learners capture and observe planaria, which are worms that eat tiny pond critters.

In this activity, learners will test the strength of different brands of paper towels.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.

In this activity, learners will take a step back and learn the history of the land they live on, and the people who used to live on it.

In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

In this activity about depth perception, learners create an optical illusion in a shoe box.

In this activity, learners build mini catapults using paint paddles and a spoon. Use this activity to introduce learners to forces and projectile motion.

In this activity, learners will explore how and why weight distribution works.

This is a guide for facilitating interaction at a touch tank with marine animals. The instructions are for setting up a display in an informal science center, but could work anywhere.

With a magnet, iron fillings, and a bottle, you can create a cool demonstration about magnetic lines of force: the fillings will arrange themselves within the magnet's magnetic field.

In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.

In this chemistry activity, learners explore density by using four solids and 6 liquids to create colorful, layered rows.

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.
