In this activity, learners will create their own bubble solution. Learners will explore chemistry, geometry and trial and error through this activity.

Learners make slime from white school glue and Borax detergent. The long chain molecules of the white glue become cross-linked by the Borax into a big network.

En esta actividad, los aprendices experimentarán con las tres fases del agua. Intentarán controlar la rapidez de los cambios de estado al manipular la temperatura y la presión del agua, hielo, y gas.

In this activity, learners will practice writing while making a fun messy craft. Learners will explore texture and color as well as develop writing and fine motor skills through this activity.

Spin in an office chair holding milk jugs! Plus, learn physics. Very fun (but stay safe) activity from the Exploratorium Science Snacks series.

Experiment with friction and make bearings for a whirligig! This activity is a nice introduction to friction and bearings and demonstrates why bearings are useful for spinning.

A simple, yet fun activity that lets learners find the center of balance of a ruler (or any long thin object). Developed by the Exploratorium and no assembly needed.

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

Learners press their fingertip onto a clean Plexiglas sheet. The fingerprints are then revealed as learners dust over the print with fingerprint powder.

In this activity, learners explore work, forces, simple machines, and construction. This lesson guide includes simple ways to demonstrate these principles as well as hands-on activities.

"Sublimation Bubbles" allows learners to explore how some solid materials, such as dry ice, can phase change directly from their solid to gaseous form.

"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water?

In this activity, learners will make their own "ball bearing" with two jar lids, marbles, and some household supplies.

In this activity about camouflage, learners create a model that shows how a flounder is able to blend into a variety of environments.

In this activity, learners build a kite out of paper, change it, and try to make it fly even better. With their new knowledge of kite making, students can then go on to create their own kite designs.

In this activity, learners make a foam packing peanut "flink"--neither float away nor sink--in water. Learners experiment with materials to make a Flinker that "flinks" for 10 seconds.

In this activity about magnetism (page 11 of the pdf), learners will experiment with magnets to explore how opposite poles attract and similar poles repel in magnetism.

In this optics activity, learners use everyday materials to make a color wheel. When learners spin the wheel like a top, they will be surprised to see all the colors mixing together to appear white.

In this activity, learners will trick out their bike with crafts and flair. Learners will explore symmetry, cause and effect and design through this activity.

This perception trick focuses on conflicting information to the brain...instead of trying to see two images, you're trying to get a bright spot by overlapping the image you see through two tubes.
