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

In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.

In this activity (on page 2 of the PDF), the learner places a golf ball between salt water and colored fresh water. The golf ball is not as dense as the saltwater.

In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

Ocean acidification is a problem that humans will have to deal with as we release more and more carbon dioxide into the atmosphere.

In this activity, learners will explore pendulum motion through scientific trials by using household items with different length strings.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

In this activity, learners create a colorful bookmark using a super thin layer of nail polish on water. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity, learners work in pairs to measure each other's ankles with lengths of string.

Doctors often send a sample of blood to a lab, to make sure their patients are healthy.

In "Exploring the Solar System: Stomp Rockets," participants learn about how some rockets carry science tools—not scientists—into space, and how a special kind of rocket called "sounding rockets" can

In this chemistry activity (on page 2 of the PDF), learners make a layered drink with liquids of different densities.

In this activity learners will explore the concepts of density and matter in their quest to answer one simple question-will it sink or will it float?

In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.

In this activity, participants will learn about how gigantic clouds of gas and dust in space, called nebulas, are formed. They'll create their own colorful model nebula using paint and a spinner.

In this activity, learners investigate what happens when you build up static electricity on plastic balls.

In this activity, learners discover that a material can act differently when it's nanometer-sized.

Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.

In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.

Learners discover that their breath contains carbon dioxide, one of the pollutants found in car exhaust.
