Create a chemical reaction that makes cheese! This hands-on activity demonstrates that molecules and atoms are tiny particles that make up everything around us.

In this activity, learners examine fingerprints. Learners leave a hidden print on a surface and then make their own print detecting powder from graphite (found in pencils).

In this activity on page 7 of the PDF, learners follow a recipe to make a dough similar to the clay artists use to make sculptures.

Using pipe cleaners, straws, and beads, learners explore the building blocks of life by creating their own model of DNA.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

In this chemistry challenge, learners identify an unknown white powder by comparing it with common household powders.

In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

In this activity, learners make their own bath bomb fizzies and experience what happens when they mix a base and an acid.

In this activity, learners create a colorful foam fountain by adding yeast to a chemical reaction. This activity introduces chemical reactions to young learners and teaches the concept of catalysts.

DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique. This activity allows you to see long, stringy strands of DNA extracted from wheat germ.

Learners write an invisible message using lemon juice on a piece of paper. They then develop the message by soaking the paper in a dilute iodine solution.

In this experiment, learners try different liquids to see which ones clean pennies best. Liquids to try include water, lemon juice, cola, vinegar, and dishwashing detergent.

In this activity, learners add dilute bleach solution to water that has been dyed with yellow, blue, and green food color.

In this chemistry challenge, learners systematically investigate which combination of four solutions produces a deep red color.

In this chemistry challenge, learners work to figure out which of four juices are real, and which is just food coloring and sugar.

In this activity, learners make film canister rocket ships. A fin pattern is glued onto the outside of the canister, and fuel (water and half an antacid tablet) is mixed inside the canister.

In this activity, learners will explore how metals react with each other. They will see these metals change before their eyes as they coat a paperclip with the copper taken from a penny.

In this activity, learners will experiment with catalysts to create an at-home version of elephant toothpaste.

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