In this activity about electricity and magnetism, learners discover how a doorbell works. A coil of wire with current flowing through it forms an electromagnet that acts similar to a bar magnet.

In this activity, learners make colored sugar and add it to water, alcohol, and oil to discover some interesting differences in dissolving.

In this experiment, learners test multiple food items to see if they are an acid or base using an indicator solution created with red cabbage.

In this quick activity (on page 2 of the PDF under GPS: Body Electricity Activity), learners will observe how dry breakfast cereal appears to dance when it gets close to a balloon charged with static

In this activity, learners make their own Sun tracker to explore how ancient civilizations around the world studied the Sun.

This is an activity about turbidity, or the amount of sediment suspended in water.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

In this chemistry activity, learners use common chemicals and metals to explore single replacement reactions.

Learners test two jars of ice water, one covered and one open, for changes in temperature. After placing the jars in the sun, learners discover that the covered jar cools down more slowly.

In this activity on page 7 of the PDF (Chemistry—It’s Elemental), learners use iodine to identify foods that contain starch.

In this activity on page 10 of the PDF, learners develop an experiment to answer the following question: "How much water can the hydrogel in a baby diaper hold?" Use this activity to explore polymers,

In this activity related to flight, learners build a tiny stream channel to investigate how fluids (air and water) change speed as they flow between and around objects.

In this activity about chemistry and electricity, learners form a battery by placing their hands onto plates of different metals.

In this activity, learners build a musical drum using a cardboard tube, plastic wrap, and beads.

In this activity, learners make self-assembled polymer spheres.

In this activity, learners describe an object they can’t see. After someone picks outs a few mystery objects and places them in a pillowcase, learners will investigate using only their hands.

In this experiment, learners use JOY liquid detergent and glycerin to make the largest bubble they can that lasts 15 seconds.

The Sacred Cenote at Chichén Itzá is a sink hole, or well, containing groundwater. In this activity, learners create their own cenote using chalk, limestone, acids, and rain water.

Learners use Benedict’s solution and heat to test for the presence of simple sugars in glucose, sucrose, starch, and starch combined with amylase.

In this STEAM activity, learners create a "pixel tube" to explore reflections of light and color mixing.
