Experiment with force and pressure by building a balloon rocket. When launched, the balloon will run a track wherever you place the string.

In this activity, learners use crayons to draw conclusions about rocks and the rock cycle.

This is an online activity about acceleration. Learners will choose a speed and an angle in order to help a water-skier named Fonzie use a ramp to clear a shark.

In this trick, learners discover how to stick a straw to the palm of their hand, window door, or anywhere using static electricity.

In this nutrition activity (page 2 of the PDF), learners will be split up into food groups (Fruit, Vegetable, Meat & Beans, Grain, and Dairy) and draw a picture of their favorite food from their g

In this activity on page 13 of the PDF, learners use a laser pointer (with known wavelength of light) to measure the thickness of a human hair.

Learners design and build a roller coaster using simple materials. Learners experiment with potential and kinetic energy to get a marble to follow a track into a cup.

In this activity, learners make critters out of recyclables and apply the rules of mathematics to solve genetics problems.

In this activity, learners will investigate and compare the root systems of plants. Explore how weed and edible plant roots differ, and take a closer look inside with the careful use of a knife!

In this data analysis and environmental science activity, learners examine the effects of pollution on amphipods using data from the Chesapeake Ecotox Research Program.

This is a quick and simple demonstration about reflexes (fourth activity on the page). One learner stands behind a see-through barrier like a window or wire screen.

This is an activity where learners will discover what types and how many insects live in their own backyard.

In this matching activity, learners play a game where they match words to the corresponding body parts of an antelope's basic anatomy.

In this engineering activity, learners design and build a mechanical arm to lift a small item.

In this activity, young learners and their caregivers use non-standard tools, like M&Ms and paper clips, to measure things around their home.

In this activity, learners explore the strength of different shapes. Fold paper into triangles, squares, and other shapes, then experiment with how much weight they can hold.

In this activity, learners balance chemical equations and discover the law of conservation of mass. Learners use coins to model molecules to balance the equations.

In this math activity, learners use what they know about shapes to copy a friend's hidden picture. Learners create a design out of pattern blocks and then hide their picture behind a screen.

In this activity, learners make a small batch of biodiesel that will work in any diesel engine. Learners use an old juice bottle as a "reactor" vessel to chemically process vegetable oil into fuel.

In this activity, learners explore a bucket of sand and beach objects.
