In this activity, learners construct a model of DNA to better understand the structure of DNA and protein synthesis.

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

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

In this activity, learners bake cookies by following different recipes to better understand genetic mutations. Everyone in the group bakes the same type of cookie: chocolate chip.

In this activity, learners receive a labeled plastic film canister containing a material representing a pollutant (i.e. pencil shavings = a beaver's wood chips).

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

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 activity, learners will explore how the human brain interprets environmental stimuli.

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.

In this activity, learners cut wells in JELL-O© and load the wells with different detergent solutions.

In this exercise (Activity #2 on page), learners test their distance vision to evaluate their overall eyesight.

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

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

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 make critters out of recyclables and apply the rules of mathematics to solve genetics problems.

This experiment allows learners to experience a small scale "epidemic," demonstrating the ease with which disease organisms are spread, and enables learners to determine the originator of the "epidemi

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.
