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

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.

In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.

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

In this cooperative game, learners devise strategies about sharing a small space with each other.

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.

This activity was designed for blind learners, but all types of learners can use it to organize an interactive model for learning the classification system (taxonomy) of living things.

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 will create paint out of natural materials. Explore your natural world (or your fridge) and find berries, leaves, or flowers to find a great base for your paint.

In this fun hands-on activity, learners whip up a batch of cyber-dough (play dough) using math for measurements.

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.

In this activity, learners create a mind and math puzzle that requires a three-dimensional solution.

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.
