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 investigate color vision as well as plan and conduct their own experiments.

In this experiment with planaria (a type of flatworm), learners will investigate the capability of different body sections to regenerate.

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.

As a long-term project, you can rear monarch butterflies at home or in a classroom.

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 explore the structure of plant leaves. Learners find out what happens when they coat either the top or bottom sides of leaves with petroleum jelly.

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

In this activity, learners create a soil and water model of a single-cell life environment and study living microorganisms.

In this activity, learners determine the necessary conditions for pea seed germination.

In this activity, learners investigate how increased carbon dioxide (CO2) emissions from the burning of fossil fuels is changing the acidity (pH) of the ocean and affecting coral reefs and other marin

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 activity, learners investigate the touch sensory system and discover how to plan and carry out their own experiments.

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

In this long-term activity, learners make a home for a colorful community of microorganisms.

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.
