This modeling activity allows learners to discover for themselves what Mendel uncovered in his famous pea experiments.

The purpose of this lab activity is to demonstrate (through simulation) how DNA fingerprinting (or DNA profiling) might be used to solve a crime.

This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.

This lab activity is about toxic substances like pesticides and their effects on biological systems. The activity starts with an introduction of how birds sequester calcium to make an egg.

In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.

In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

This activity allows learners to explore the scientific method in an open-ended fashion, using the 4-P Approach to Science Inquiry developed by the University of Wisconsin, Beloit.

In this highly collaborative activity, learners design and complete a controlled experiment which attempts to answer a simple question about the slime mold Physarum.

Using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, learners study the role of light in photosynthesis.

In this activity, learners will examine a variety of seeds, describe them, and determine how they are dispersed.

In this activity that can be used as a lab or demonstration, learners use Lactaid® and lactose to demonstrate the concept of enzyme action.

In this lab (Activity #1 on page), learners explore how we see color.

This laboratory activity helps learners understand the concept of biological succession by simulating the process in a microenvironment with various protozoans.

In this open-ended multicultural lab activity, learners investigate the effectiveness of herbal remedies.

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.

The purpose of this lab is to recognize that the answers to some of society's industrial challenges may lie right in our own backyards.

This three-part lab helps learners understand the essential principles governing diffusion and osmosis.

In this lab, learners evaluate the relative effectiveness of various chemical substances (i.e. garlic powder, bathroom cleaner, mouthwash, etc.) as antimicrobial agents.

In this series of exercises, learners predict the conditions necessary for bacterial growth, test their predictions and at the same time practice the aseptic techniques and safety procedures needed wh

In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.
