In this activity, learners work in small groups to match various marine animals with their different environments.

In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.

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 water activity, learners discover ways to move water across the water table.

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 explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.

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 measure and calculate the amount of cubic feet various containers contain. Next, learners investigate cubic feet per second (cps), by carrying jugs in one second.

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.

Experiment with friction and make bearings for a whirligig! This activity is a nice introduction to friction and bearings and demonstrates why bearings are useful for spinning.

In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.

In this design challenge activity, learners build a car that uses a battery-operated motor to "drive" at least ten feet.

In this activity, learners use crayons to draw conclusions about rocks and the rock cycle.

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 trick, learners discover how to stick a straw to the palm of their hand, window door, or anywhere using static electricity.
