Model the Sun and Earth
Source Institutions
In this activity, learners make scale models of the Sun and Earth out of paper mache.

Build a Battery
Source Institutions
Learners build a simple one-cell battery and use an ammeter to measure the flow of current.

Save a Snowman
Source Institutions
In this activity, learners explore the concept of insulation by trying to keep Olaf the Snowman from melting. This activity encourages critical thinking and problem solving.

Masses & Springs
Source Institutions
In this online activity, learners use a realistic mass and spring laboratory. They hang masses from springs and adjust the spring stiffness and damping.

Wheat Evolution: Dough Washing
Source Institutions
In this activity (Page 22 of PDF), learners investigate the evolution of wheat by washing different types of dough with water and comparing the results.

Wheat Evolution: Dough Rising and Baking
Source Institutions
In this activity (Page 25 of PDF), learners investigate the evolution of wheat by creating dough from different flours, observing the samples of dough as they rise, and then baking the dough.

Translating an Alien Message
Source Institutions
In this activity, learners work together to interpret an "alien message." The group pretends that this is the only message from an imaginary civilization, so there is no "key" and thus no "correct" wa

Scribbling Machines
Source Institutions
In this activity, learners explore electronics and motion by making a Scribbling Machine, a motorized contraption that moves in unusual ways and leaves a mark to trace its path.

Chemistry is Colorful
Source Institutions
In this activity, learners explore materials through paper chromatography.

Potato Straw
Source Institutions
In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.

Mystery Sand
Source Institutions
In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

Silver Crystals
Source Institutions
This is written as a static display, but can easily become a hands-on experiment for learners.

Balancing Sculptures
Source Institutions
In this activity, learners will use a variety of household and/or natural objects to design a sculpture that balances from a single point.

Rolling Action Art
Source Institutions
In this activity, learners of all ages will roll a ball coated with paint to artistically visualize the motion of the object.

Engineer A Bird Feeder
Source Institutions
In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.

Trading Places
Source Institutions
In this activity, learners discover that atoms and ions of different metals will change places.

Got Seaweed?
Source Institutions
In this activity, learners examine the properties of different seaweeds, investigate what happens when powdered seaweed (alginate) is added to water, and learn about food products made with seaweed.

Zoom-A-Rang
Source Institutions
In this activity, learners design and build a Zoom-a-rang using everyday materials. Experiment with different materials and Zoom-a-rang designs to see how they fly.

Bone Fractures
Source Institutions
Most people break at least two bones in their lifetime. In this activity, learners will use celery stalks to model the many ways that bones can fracture.

It's all Done with Mirrors
Source Institutions
This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.
