In this chemistry activity, learners will explore the concept of entropy. When learners stretch and unstretch a balloon, they will notice a change in temperature.

In this weather activity which requires adult supervision, learners will get a chance to make a cloud right here on Earth!

In this physics activity (page 3 of the PDF), learners will explore the concept of static electricity.

What keeps bubbles and other things, like airplanes, floating or flying in the air?

Is this activity concentrating on physical science, learners build their very own miniature hovercraft out of a paper cup. Using it, they can explore the concepts of friction and force.

In this engineering activity, learners test the stability of towers they build out of cups, discovering that structures with more mass in the base are more stable.

In this biology experiment, learners plant soybean seeds in plaster of Paris, witnessing firsthand the mighty power and ability of plants to grow in adverse conditions.

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 physics activity (page 6 of the PDF), learners will explore how static electricity affects surrounding objects.

In this activity about tangrams, learners print and cut out their own tangram shapes and solve puzzles by fitting these geometric pieces together in a variety of ways.

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 biology activity, learners recreate the process of digestion in a zip lock bag. A bit of soda pop added to some crumbled crackers approximates how acids in the stomach dissolve food.

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

In this math activity, learners will create a scale diagram of their backyard or other outdoor area on graph paper.

In this chemistry activity (page 5 of the PDF), learners will see that chewing is more than just the crushing up of food; there is actually a chemical change going on at the same time.

In this physics activity (page 3 of the PDF), learners will see firsthand that air takes up space and has pressure by attempting to inflate a balloon inside of a bottle.

In this fun math activity (page 1 of the pdf), learners exercise the creative part of their brain by trying to describe a number without mentioning the actual number (for instance, the number 12 could

In this chemistry activity, learners witness an exothermic reaction, while making their very own, completely usable sidewalk chalk. This is also an excellent activity for exploring color mixing.
