Learners carefully look at four known household crystals.

In this activity, learners write invisible messages on goldenrod paper, and make the message appear and disappear using acids and bases.

In this activity, learners explore the relationship between cooling water vapor and condensation. Learners investigate condensation forming on the outside of a cold cup.

In this activity on page 5 of the PDF, learners compare water with artificial urine to see how urinalysis works. Learners use urinalysis test strips to test for glucose and protein in the fake urine.

Learners design their own experiment to determine which M&M color dissolves the fastest in water.

In this activity on page 11 of the PDF, learners follow simple steps to recycle old newspaper into new paper.

In this activity on page 6 of the PDF (Get Cooking With Chemistry), learners investigate yeast. Learners prepare an experiment to observe what yeast cells like to eat.

In this activity on page 6 of the PDF, learners dissolve Epsom salt in water and discover that the resulting solution can be used to create a work of art.

Learners create hard water by mixing Epsom salt and water. Then they compare what happens when soap solution is mixed with hard water and regular water.
