In this activity about weights and balances, learners create their own balance using paper cups. Then, learners explore how to compare the relative mass of objects.

In this biology activity (page 6 of the PDF), learners roll a die to create a simple model that teaches them about the factors contributing to heart disease.

In this activity, which requires adult supervision, learners get to explore the awesome power of chemistry.

In this playful physics activity (page eight of the pdf), learners use toy cars to explore how speed and weight affect the results of collision.

In this activity, learners explore why frost forms. They create their own frost using a solution of ice water and salt in a glass.

In this forensics activity, students will explore the methods that investigators use to confirm the authenticity of handwriting.

In this physics activity, learners will investigate the strength of egg shells.

In this physics activity (page 4 of the PDF), learners will explore how similar magnetic poles repel one another. They will rely on linear induction to race magnets around a simple course.

In this activity, learners construct a rocket powered by the pressure generated from an effervescing antacid tablet reacting with water, and build a launch pad for their rocket.

In this physics activity (page 6 of the PDF), learners will build a class 1 lever and hypothesize and test the distances two objects need to be placed from the fulcrum in order to balance.

In this activity about states of matter, learners get to witness firsthand the awesome power of air pressure. They watch as an ordinary soda can is crushed by invisible forces.

In this biology activity (page 8 of the PDF), learners will explore how saliva assists in the beginning of the digestive process.

In this chemistry activity (page 5 of the PDF), learners will use milk and a few other basic ingredients to create a chemical change to make a color wheel.

This is an activity about the behavior of light. Using simple, everyday objects, learners will discover that light moves in straight lines until acted upon by another object.

In this classification activity, learners will learn one way of organizing plants and animals.

In this amazingly simple physics activity (page 5 of the PDF), learners will explore how exerting a force on an object can give it kinetic energy and momentum.

In this physics activity (page 3 of the PDF), learners will move a load using a lever of each of the 3 classes. They will explore the differences between these classes and which are more effective.

In this geology activity (page 6 of the PDF), learners explore how carbonic acid can slowly dissolve limestone and form caves.

In this activity about potential and kinetic energy, learners get to roll a can across the floor and then watch it roll back to them as if by magic. This activity is always great for looks of wonder!

In this activity, learners will explore their center of gravity.
