In this food science activity, learners explore digestion and proteins by observing the action of meat tenderizer on luncheon meat.

Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.

In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.

Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.

Learners compare the weight of equal volumes of wax, water, and clay. Learners discover that since the wax weighs less than an equal volume of water, it is less dense than water and will float.

Learners create hard water by mixing Epsom salt and water. Then they compare what happens when soap solution is mixed with hard water and regular water.

In this activity, learners build models of atoms and molecules, then consider their role in different phases of matter, density, and mixtures and solutions.

Learners will see that changing the shape of an object, like a clay ball, that is more dense than water, can affect whether the object will sink or float.

This three-part activity consists of an activity that groups of learners develop themselves, a given procedure, and an optional demonstration.

Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.

In this activity (located on page 2), learners will construct tiny model geysers out of film canisters, warm water, and antacid seltzer tablets.

In this activity (on pages 11-12 of PDF) learners create models of lava layers that have formed on the moon.

In this hands-on activity, learners build their own kaleidoscopes and explore how light can reflect of off surfaces such as mirrors, to produce beautiful patterns.

This resource contains several mini-explorations using a slide projector as a light source to investigate light and the properties of images.

Learners design their own experiment to determine which M&M color dissolves the fastest in water.

Learners add different liquids (water, salt water, alcohol, and detergent solution) to water and observe the different ways the different liquids combine with water.

In this activity, learners investigate whether having sugar already dissolved in water affects the speed of dissolving and the movement of sugar and color through the water.

Learners build a yo-yo using a piece of wood, PVC pipe, and string. In doing so, learners explore the force of gravity and angular momentum.

Learners add calcium chloride to a baking soda solution and observe an increase in temperature along with the production of a gas and a white precipitate. These are all signs of a chemical reaction.

In this activity, learners explore the relative sizes and distances of objects in the solar system.
