Align four color transparencies, each one a single color (cyan, magenta, yellow, and black), and see a beautiful full color image.

In this activity, learners create a xylophone by filling glasses with different amounts of water and tapping them with a metal spoon.

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, "write" a secret message in genetic code as beads on a string.

In this creative activity, learners will find out what makes an insect an insect by studying examples of insect adaptations and by examining why there are so many different types of insects.

In this activity, learners explore why the sky is blue. Learners model the scattering of light by the atmosphere, which creates the blue sky and red sunset, using a flashlight and clear glue sticks.

In this activity, learners make their own bug boxes and test the habitat preference of selected "minibeasts" (bugs).

In this activity, learners start their own field journal to better understand the wildlife in their area.

The purpose of this plant biotechnology activity is to demonstrate the effect of changes in the environment on the growth and fertility of landscape grasses and crop grasses such as wheat and rice.

In this activity, learners capture and observe planaria, which are worms that eat tiny pond critters.

Learners use several types of insect sampling and collection equipment to make an insect collection. Learners can collect insects from their schoolyard or yard at home.

In this activity, learners work in groups to match craft sticks that represent chromosomes. Learners must define critical attributes of their chromosomes as they look for matching chromosomes.

Learners add drops of alginate solution to a solution of calcium chloride. The alginate does not mix with the calcium chloride, but forms soft gel beads.

In this activity (page 12), learners apply the concepts of pixilation and pointillism to the world of biomedical science.

In this hands-on nature activity, learners observe the emergence of leaves and flowers. Branches from trees and bushes are collected in the early spring, brought indoors, and placed in water.

In this nutrition activity (page 2 of the PDF), learners will be split up into food groups (Fruit, Vegetable, Meat & Beans, Grain, and Dairy) and draw a picture of their favorite food from their g

This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour

In this outdoor activity, learners first explore lizard feeding behavior by creating a "lizard rig" to dangle different objects in front of live lizards and see which objects the lizards try to bite.

In this activity, learners make critters out of recyclables and apply the rules of mathematics to solve genetics problems.

In this activity, learners will investigate and compare the root systems of plants. Explore how weed and edible plant roots differ, and take a closer look inside with the careful use of a knife!
