In this activity about food safety and nutrition, learners investigate safe food preparation by making fruit ice cream.

Some animals can swallow food whole, but humans have to chew. In this activity, learners will investigate what saliva does chemically to food before we even swallow.

In this chemistry activity, learners will separate a mixture of FD&C dyes (colors certified and allowed by the US for the Food, Pharmaceutical, Cosmetics & Personal Care industry) to practice

In this simulation, learners act out each digestive function of the organs, tissues, and cells in the digestive tract.

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

In this yummy earth science activity (page 5 of the PDF), learners use fudge to learn about different kinds of lava.

In this activity, learners use three types of cheesy snacks--cheese balls, cheese puffs, and Cheetos--to learn about polymers.

Albert Einstein proved that space bends around anything that has mass. This activity uses Jell-O's ability to bend around objects as a model for space bending around planets and stars.

In this Energy and Environment activity (page 9 of the PDF), learners calculate the mass of a piece of gum, compare it to the mass of the gum's packaging, and then create a bar graph of the results.

In this chemistry meets cooking activity, learners compare the stability of egg white foams with various additives.

Learners work in groups to construct bridges using stale marshmallows and toothpicks.

This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

In this activity, learners make their own solar oven to bake s'mores and learn about how solar energy is absorbed on Earth.

This exercise is designed to teach young learners the different parts of a plant (root, stems, leaves, flowers, fruit, and seeds), the basic functions of each part, and to show that tiny microscopic o

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

In this activity, learners use a model for how fishing affects marine life populations, and will construct explanations for one of the reasons why fish populations are declining.
