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.

Learners observe a model of a cell and its chromosomal DNA made from a plastic egg and dental floss. Use this model to illustrate how much DNA is held in one cell.

Explore the effects of gravity on a slowly falling object: a parachute you make out of plastic bags, string and stones.

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

In this neuroscience activity, learners conduct a simulation to demonstrate how multiple incoming signals influence the action of neurons.

In this activity about the baroreceptor reflex (BR) arc (page 123 of the PDF), learners discover the importance of maintaining adequate arterial blood pressure through a role playing exercise.

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

Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.

In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

In this activity, learners predict where a ball will go after it bounces off another object. Learners discover that the motion of objects is predictable based on laws of motion.

Learners set up books with rubber bands stretched between the books. When two identical books are stretched apart and released, they move back toward each other an equal distance.

In this activity, learners work with an adult to build a rocket and launcher out of a plastic 2-liter bottle, flexible plastic hose, plastic tubing, toilet paper tube, and duct tape.

Create 3D glasses and use them to explore color, light and optics. Fool your brain into 'seeing' three dimensions on a flat surface!

In this activity, learners use multiple thermometers, placed at different angles, and a lamp to investigate why some places on Earth's surface are much hotter than others.

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.

In this activity, learners extract DNA from wheat germ. Use this activity to introduce learners to DNA, biotechnology and genetic engineering.

In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

Learners add drops of four liquids (water, alcohol, salt water, and detergent solution) to different surfaces and observe the liquids' behavior.
