In this activity, learners discover a trick to release the air out of a balloon without popping it.

In this activity, learners use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. Learners discover that convection drives wind on Jupiter and on Earth.

In this math lesson (page 2 of the PDF), learners use bottles of various shapes to explore the abstract concept of rate of change.

In this math activity (Page 10 of the Play Ball! PDF), learners play a game of "football" and analyze the results of the game.

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.

Conduct a simple experiment to explore how temperature changes can make things expand or contract.

Learners imagine they are paleontologists in Florida, where they find (remove from envelope) paper "fossils" of some unknown creature, only a few at a time.

In this activity, learners place cards featuring biological structures in order by their relative size from largest to smallest.

In this activity, learners will create unique rockets. Each rocket will be powered by air as the learner will blow into a straw and watch their rocket fly.

In this demonstration, learners attempt to get a large coin through a small hole, the size of a smaller coin.

Learners create a tool to measure how well they grip a wet object when their fingers are smooth versus wrinkly. Are smooth or wrinkly fingers better at holding on to the object?

In this activity, learners will observe how air interacts with a paper helicopter. Learners will test different variables of weight, size, and shape.

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

In this activity, learners will create a home for animal friends in their backyard using recycled materials. Some material suggestions include: pine straw and twigs.

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

This is a quick activity (on page 2 of the PDF under Hockey Sticks Activity) about how the arrangement of carbon atoms determines carbon's different properties.

In this activity, learners gain a better understanding of how household/school waste breaks down in a landfill. Learners collect trash and then create miniature landfills in 2-liter bottles.

In this chemistry activity (on page 2 of the PDF), learners corrode a penny in a cup with vinegar, salt water, and a source of iron (nails, paper clips, or twist ties).

In this activity, learners turn an ordinary metal coat-hanger into a (very quiet) musical instrument.
