In this outdoor activity and bingo-like game, learners explore why and how seeds spread far from the plants that produce them.

This marine biology activity (on pages 11-17) introduces learners to kelp (seaweed) forests that grow in the ocean and are home to many species of sea animals.

Learners discover the bubble power of living cells in this multi-hour experiment with baker's yeast. Learners make a living yeast/water solution in a bottle, and add table sugar to feed the yeast.

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.

Learners use a simple process to extract DNA from strawberries.

This is a culminating activity which allows learners to summarize what they know about Woodlands Native Americans by creating illustrations and map symbols for a large outline map (see related Activit

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, learners explore why animals, specifically dinosaurs, live in families.

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

This activity (on pages 10-12 of the PDF) encourages learners to consider what makes living things different from non-living things.

In this activity, learners make a model of a beehive using simple materials.

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 activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.

Learners design different shaped bandages for different purposes. First, they draw their designs on paper.

In this activity about the relationship between food and energy (page 1 of PDF), learners observe and quantify the growth of yeast when it is given table sugar as a food source.

In this experiment, learners isolate Deoxyribonucleic Acid (DNA) from onion cells using a simple extraction procedure.

Many common household cleaners are antimicrobials.
