In this activity, learners extract DNA from wheat germ. Use this activity to introduce learners to DNA, biotechnology and genetic engineering.

In this activity, learners make slides of onion cells and their own cheek cells. Use this lab to teach learners how to prepare microscope slides and use a microscope.

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

This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells. It includes an optional test for the presence of DNA.

In this activity, learners investigate the olfactory system by conducting several experiments.

In this kinesthetic activity, learners move pom-pom "ions" across a membrane to simulate how an action potential is propagated along an axon.

The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.

In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

In this simulation, learners act out each digestive function of the organs, tissues, and cells in the digestive tract.

In this activity, learners use a microscope to examine three different microbes: bacteria, yeast and paramecia. Educator will need to prepare the yeast solution one day before the activity.

In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.

Why does milk make some people sick? In this activity learners explore this question and explore the chemistry of milk, and our bodies!

In this activity, learners use edible models of the DNA molecule to transcribe an mRNA sequence, and then translate it into a protein.

In this activity, learners build edible models of DNA, while learning basic DNA structure and the rules of base pairing.

This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells using simple materials.

In this activity on page 9 of the PDF, learners test how flavoring extracts move through the walls of a balloon.

This laboratory exercise is designed to show learners how DNA can easily be extracted from yeast using simple materials.

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
