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.

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 activity, learners explore how ordinary marshmallows expand when heated in a microwave.

In this activity, learners touch supercooled water drops with an ice crystal and trigger the water drops to freeze instantly.

In this activity, learners explore the concept of density by pouring 5 different liquids into a jar. Food coloring is added if needed to give each liquid a distinct color.

Using two baby food jars, food coloring, and an index card, you'll 'marry' the jars to see how hot water and cold water mix.

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

In this activity, learners will make their own slushies and learn some of the science behind how the process works.

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 model hot spot island formation, orientation and progression with condiments.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

In this a hands-on activity, learners explore how to put ice cream in an oven without it melting. Ideas in this activity include insulation and cooking.

In this chemistry activity (page 1 of the PDF), learners will observe a physical change.

In this activity, learners add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules.

Learners set up three different bowls, each with a different mass of oatmeal. Learners monitor the temperature of the oatmeal and find that larger masses take longer to cool.

Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.

In this activity on page 5 of the PDF, learners mimic the process for making bricks. Learners shape and bake creations from a dough that is made from flour, salt, and water.

Learners design their own experiment to compare how well cocoa mix dissolves in cold and hot water. They will see that cocoa mix dissolves much better in hot water. Adult supervision recommended.

Learners build a simple solar oven from a shoebox, black construction paper, and aluminum foil. Over the course of a few hours, the oven heats up water enough to brew tea.

In this chemistry activity, learners perform three chemical reactions in a sealed zip-top bag. Learners will record their observations and classify the changes as chemical or physical.
