In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

Learners and their families celebrate and recognize the importance of making healthy choices every day by participating in a health fair.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

In this activity (5th activity on the page), learners explore how what you see influences taste. In experiment 1, learners taste five sodas, one of which is clear soda with orange food coloring.

In this culinary activity, learners use multiple senses (sight, smell, touch, and taste!) to explore real seaweed samples.

In this chemistry challenge, learners work to figure out which of four juices are real, and which is just food coloring and sugar.

In this chemistry activity, learners make indicator solution from red cabbage. Then, learners test everyday foods and household substances using the cabbage juice indicator.

In this activity, learners will create beautiful greeting cards by marbling with shaving cream and food dye. They will explore the chemistry behind the art of marbling.

In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.

In this yummy biology activity (page 3 of the PDF), learners participate in a demonstration of natural selection.

In this physics activity, learners experiment with the attractive and repulsive power of magnets.

In this physics activity, learners attempt to lift a jar full of rice using only a spoon.

In this activity, learners eat a snack and make a model of the plumbing system of a volcano.

In this activity, learners use Starburst® candy to sort, classify, compare, and graph. Learners grab a handful of one-inch candy squares, sort them by color, graph the candy, and discuss the results.

In this activity (page 7 of the PDF), learners will investigate the contents of owl pellets. Learners will discover how owls digest their food as well as the kind of animals they eat.

In this activity, learners explore the concepts of density and basic chemical reactions as they create a homemade lava lamp effect using water, oil, food coloring, and Alka-Seltzer tablets.

In this math lesson, learners use fruit to learn about proportions and percentages. Learners compare the weights of the edible and non-edible portions of fruit.

In this math lesson, learners use slices of bread and geoboards to explore several ways to divide a rectangle in half. Learners also identify equivalent fractions that represent one-half.

In this chemistry activity, learners will learn how to make their own pH indicator using cabbage leaves, and then test common household items with their homemade indicator.
