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.

This is a fun activity about the power of the Sun and the importance of using sunscreen to protect your sensitive skin from its rays.

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.

In this fun hands-on activity, learners whip up a batch of cyber-dough (play dough) using math for measurements.

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.

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

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 use their senses to collect information about a fruit and record their findings in a Science Journal.

In this fascinating and fun experiment, learners use chemistry to identify a mystery powder and to solve a "crime," a process similar to that used by real forensic scientists.

In this hands-on science experiment, students combine their understanding of the different states of matter and the characteristics of various chemical reactions.

In this math lesson, learners explore tessellations through literature, music, writing, and art activities.

In this activity, learners discover how a cabbage juice indicator helps identify acids and bases, and how iodine indicates the presence of starch.

Learners explore soybeans, soak them in water to remove their coat, and then split them open to look inside. They also make a musical shaker out of paper cups, a cardboard tube, and soybeans.

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 exercise is designed to teach young learners the different parts of a plant (root, stems, leaves, flowers, fruit, and seeds), the basic functions of each part, and to show that tiny microscopic o

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
