In this activity, learners will explore vegetative propagation while preparing food scraps to grow into plants.

In this activity (4th activity on the page), learners test to see if saliva is necessary for food to have taste.

This lesson is designed to serve as an introduction to the immune system. It can stand alone or it can lead into further studies of the immune system.

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

In this genetics activity, learners extract DNA from an onion, using detergent solution, a food processor, and rubbing alcohol. They will also discuss genetic engineering of plants.

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

In this activity, learners use food scraps from the kitchen to grow new vegetables.

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

In this activity, learners are challenged to eat some candy as a cell would need to as well as to think about some of the problems that arise when a cell ingests food.

In this activity, learners conduct tests for proteins, glucose, and starch.

In a series of three experiments, learners explore the basics of biotechnology using self-locking plastic baggies. Each experiment demonstrates a phenomenon or principle of biotechnology.

In this activity, learners make a yeast-air balloon to get a better idea of what yeast can do. Learners discover that the purpose of leaveners like yeast is to produce the gas that makes bread rise.

In this activity about osmosis, learners use a naked egg (one with a dissolved eggshell) to learn about selectively permeable membranes.

Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.

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 construct a cereal chain as a model of how proteins are made in the cell.

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

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

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