Learners make their own acid-base indicator from red cabbage. They use this indicator to test substances around the house.

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

In this playful activity, learners explore the structure of the cell—the basic unit of every living organism—by creating a model of cell structures using soap bubbles, and by examining a slice of onio

In this activity, learners use detergent solution to compare two solutions containing vinegar and cream of tartar.

In this activity, learners explore a bucket of sand and beach objects.

Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.

Learners investigate how temperature affects the rate of chemical reactions by observing how steel wool reacts with various types of Kool-Aid solutions at different temperatures.

An outdoor scavenger hunt helps learners consider the theme of "What Is Life?" Learners explore what living organisms are, including how organisms meet basic needs of food, shelter and water to surviv

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

Many germs spread by our hands, and often times, people don't wash their hands well enough to get rid of germs.

In this activity (on page 2 of the PDF), learners make a plastic protein polymer from milk. Adding vinegar to milk causes the protein casein to solidify or curdle.

In this activity, learners make balloon models of disease-causing bacteria.

In this activity, learners explore the different salinities of various sources of water by taste-testing.

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.

This lesson gives full instructions for making cabbage juice indicator, a procedure sheet for learners to record observations as they use the indicator to test materials, and extension activities to d

In this activity, learners build models of comets, using edible materials, to learn about comets' structure.

In this activity on page 2 of the PDF, learners test different materials to find out which is the best insulator.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

In this activity, learners follow clues to find five puzzle pieces, then assemble them. This activity works well with a whole group, individuals, or families.
