In this activity, learners will turn cream and salt into butter—using marbles. Learners will explore how shaking up fat globules help them create homemade butter.

In this activity on page 7 of the PDF (Chemistry—It’s Elemental), learners use iodine to identify foods that contain starch.

In this activity, learners experiment with how dish soap and fat interact by making a colorful swirl.

In this experiment, learners test multiple food items to see if they are an acid or base using an indicator solution created with red cabbage.

Capture soap bubble patterns on paper! In this activity, learners can create beautiful pictures from popping soap bubbles.

In this activity, learners test different food items by timing how long it takes each liquid to slide from the top of a ramp to the bottom.

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

In this chemistry investigation, learners combine common cooking substances (flour, baking powder, sugar, salt, pepper, oil, water, food coloring) to explore mixtures.

In this activity about magnetism (page 17 of the pdf), learners experiment with magnets, exploring the concept of diamagnetic materials by seeing how a grape reacts to a magnetic field.

Learners analyze candy-coated sweets using chromatography. Learners use this method to separate the various dyes used to make colored candy.

In this physics activity, learners will investigate the strength of egg shells.

This open-ended art project allows learners to create their own colorful ice sculpture by using rock salt and food coloring on a solid block of ice.

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.

Don't scream for ice cream -- make it with milk, sugar, flavoring and some 'salt-water' ice. Discover the chemistry of ice cream by creating your own.

In this activity, learners make instant ice cream without using a freezer.

In this activity, learners use oil, water, food coloring and antacid tablets to create a bubbling lava lamp. Use this activity to introduce concepts related to density, hydrophobicity vs.

In this optics activity, learners use a shoebox, colored cellophane and sunlight to "change" the colors of gumballs. Learners will be surprised when the green and blue gumballs appear black!

In this activity on page 7 of the PDF, learners follow a recipe to make a dough similar to the clay artists use to make sculptures.

In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.

Learners use their knowledge of color changes with red cabbage indicator to neutralize an acidic solution with a base and then neutralize a basic solution with an acid.
