Learners use red cabbage juice and pH indicator paper to test the acidity and basicity of household materials. The activity links this concept of acids and bases to acid rain and other pollutants.

In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.

In this biology activity (page 8 of the PDF), learners will determine whether they are "tasters" or "non-tasters", test selected individuals from their families and peer group for the trait, and chart

In this activity, learners explore what happens when polarized white light passes through a sugar solution.

This activity (on pages 16-23) lets learners measure each other's vital signs—the signs that help doctors understand what's going on in a patient body.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this activity, learners will make seed orbs to grow new trees and plants. Learners will explore ecology and life cycles as well as stewardship through this activity.

This activity models the necessary balance of creating power and cleaning up its associated waste. Learners participate in a game where they attempt to move forward toward a goal.

In this activity about dinosaurs, learners first participate in a group discussion about where and when dinosaurs lived, how big they were, and who studies them and how.

This is an activity about dinosaurs, fossils, and the work of paleontologists. Learners use hand tools (paint brushes, scoops, and sifters) to unearth fossil specimens in tubs of birdseed.

In this activity about afterimages, learners explore what happens when receptor cells called cones in your eye's retina get tired.

In this activity, learners explore why animals, specifically dinosaurs, live in families.

In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the

In this investigation learners explore the differences between, and interdependence of, living and nonliving elements in a water ecosystem.

In this activity about depth perception, learners create an optical illusion in a shoe box.

In this activity about the relationship between food and energy (page 5 of PDF), learners conduct an experiment to compare how much energy is released as heat from two different foods.

Learners design their own experiment to investigate how pollution diffuses through ground material.

In this hands-on activity, learners will become familiar with the special adaptations of rainforest plants and discover the conditions needed for tropical trees to survive along with what can impinge

In this optics activity, learners explore diffraction by adding wax blocks to a ripple tank. The wedge-shaped blocks act as obstacles that the wave must bend around.

In this delicious activity, learners get to make, taste-test and compare their own "brands" of homemade strawberry ice cream.
