In this activity learners will measure and manipulate flubber using different tools. Learners will explore volume and make observations about texture and shapes.

“Exploring the Solar System: Ice Orbs” is a hands-on activity in which visitors investigate a frozen orb, trying to learn about objects hidden inside.

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

In this activity, learners explore the unseen force of friction and how surfaces can slow moving objects at different rates.

Learners use chromatography to separate and analyze the mixture of pigments in leaves. Use this activity to discuss photosynthesis as well as why leaves change color in autumn.

In this physics activity, challenge learners to make a race-car out of a coffee can and rubber band. Demonstrate motion, forces, kinetic and potential energy and friction.

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.

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.

In this activity, learners will participate in a scavenger hunt involving sizes, shapes, and numbers. This activity works well with a whole group, individuals, or families.

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 will make predictions and experiment with different objects to see if they sink or float.

This fun and simple activity is a rubberband rocket design challenge! Learners will explore how tail fins can help to stabilize a flying object, while also exploring potential and kinetic energy.

In this activity, learners use a soda can to decode a secret message. Learners wrap scytale (pronounced ski-tally) code around a can and challenge friends to see if they can crack the codes.

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.

How much can you do in one minute? In this activity, learners estimate how many times a partner can complete a task (like writing their name or jumping jacks) in one minute.

In this quick activity about pollutants and groundwater (page 2 of PDF under Water Clean-up Activity), learners build a model well with a toilet paper tube.

In this physics activity (page 2 of the PDF), learners will explore the concept of thermal conductivity and learn the differences between high and low thermal conductivity.

In this physics activity (page nine of the pdf), learners use balloons to explore how a rocket works. It is suggested they also work to see how they can alter the velocity of the rocket.

In this activity (5th activity on the page), learners explore how what you see influences taste. In experiment 1, learners taste five sodas, one of which is clear soda with orange food coloring.
