Students design and create their own air-powered rockets, in this hands-on activity.

In this activity, learners play a simple card game to learn the sequence of events in the transmission of nervous system signals.

Create a chemical reaction that makes cheese! This hands-on activity demonstrates that molecules and atoms are tiny particles that make up everything around us.

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.

This is an activity about a very important ingredient in most baked goods - gluten! Why is gluten so important? Without it, there would be nothing to hold the gas that makes bread rise.

Learners observe projectile motion by launching wooden balls off of a table top. They set up a rubber-band launcher so that each ball experiences a consistent amount of force.

In this activity, learners hook up a hair to a lever system and create a hair hygrometer to measure changes in humidity.

In this activity, learners cut out a fish and then "paint" it using universal indicator and acids and bases.

In this activity, learners discover that some things only stand up while they are spinning.

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

In this activity (on page 2 of the PDF), the learner places a golf ball between salt water and colored fresh water. The golf ball is not as dense as the saltwater.

In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.

In this activity, learners explore how objects can have positive, negative, or neutral charges, which attract, repel and move between objects.

This lab activity has learners create a pendulum with a one-second period.

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.

In this activity, learners create a traditional Mexican noisemaker (a matraca) using cardboard, craft sticks, and a wooden dowel.

Learners will compare the growth rate and appearance of crystals forming on small rocks to those growing on miscellaneous objects. Learners will also investigate how temperature (warm vs.

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.
