In this activity, learners will use clear nail polish and the power of chemistry to create paper with a rainbow sheen.

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

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 activity, learners discover that nanoparticles of gold can appear red, orange or even blue. They learn that a material can act differently when it’s nanometer-sized.

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

In this activity on page 11 of the PDF, learners use candle wax to make "invisible" designs that are revealed with watercolor paints.

In this activity (7th activity on the page), learners use their sense of hearing to find a "sound match." Learners shake containers filled with items like dry seeds, sand, beans, etc.

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.

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.

In this activity, explore chromatography and the various colors that make up the ink in markers. Use this activity to investigate cohesion and adhesion.

In this demonstration/activity, water streaming through holes in the bottom of a suspended soda pop can causes the can to rotate.

In this simple activity, learners see the production of a gas, which visibly fills up a balloon placed over the neck of a bottle.

In this activity, learners sniff out scents hidden in balloons! After investigating, learners discover we sometimes can use another sense (smell) to detect things too small to see.

In this activity, learners use a flexible magnet as a model for a scanning probe microscope (SPM). They learn that SPMs are an example of a special tool that scientists use to work on the nanoscale.

Learners mix a solution containing luminol and copper with a fake blood solution. A chemical reaction between the luminol solution and fake blood (hydrogen peroxide) show learners a blue glow.

In this simple activity, learners investigate refraction by placing a picture of an arrow behind a glass of water.

In this activity, learners make models representing bones on Earth and bones that have been in space. They discover what happens to bones without proper exercise and nutrition.

In this chemistry activity, learners use guar gum to make slime. Use this activity to introduce learners to polymers, viscosity, and colloids.
