In this hands-on experiment, kids use chemistry to explore whether acids or bases are better at restoring a penny’s shine.

In this activity, learners mix up a bubbly brew and examine density. Learners explore how they can make different materials fall and rise in water using oil, water, and salt.

In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

In two separate bags, learners mix water with Epsom salts and detergent.

In this environmental health activity, learners investigate their own vital lung capacities.

In this activity, learners make an optical illusion toy from the 1800s to explore persistence of vision.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

In this activity (on pages 29-35), learners examine water pollution and filtration.

This activity (on pages 38-43) has learners simulate the way scientists track and map the movement of otters in the wild using radio trackers.

In this activity, learners mix several sugar solutions to investigate the property of density. Each sugar solution has a different density and color of the rainbow.

In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.

This activity (on pages 13-18) has learners build a model tree and then figure out how to make their tree stand up by itself.

This reading and writing activity (on pages 2-9) teaches what plant parts should be avoided, how a person can get rid of toxins, symptoms of plant poisoning, and how plants create poisons to repel pre

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,
