In this activity, learners will use clear nail polish and the power of chemistry to create paper with a rainbow sheen.
Body Parts
Source Institutions
In this online game, learners test their knowledge of human anatomy.
Exploring Materials: Nano Gold
Source Institutions
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.
Clues About Clouds
Source Institutions
In this weather activity which requires adult supervision, learners will get a chance to make a cloud right here on Earth!
Screen Time
Source Institutions
This game asks you a series of questions about how much time you spend in front of a screen, not being active.
Box Ecology
Source Institutions
This great "re-use it" activity will demonstrate how to transform a greeting card into a box. Once constructed, the box can have many uses like holding special notes or keepsakes.
Guess My Number
Source Institutions
In this game, learners experience how computers divide a big problem into many smaller ones and how they use binary "yes"/"no" questions.
Salt 'n Lighter
Source Institutions
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.
Rate It: Working With Zero and Negative Numbers
Source Institutions
In this activity, learners will rate the day, a book, or something else on a scale from -2 to 2. This activity works well for groups of all ages.
Soda Pop Can Hero Engine
Source Institutions
In this demonstration/activity, water streaming through holes in the bottom of a suspended soda pop can causes the can to rotate.
It's a Gas!
Source Institutions
In this simple activity, learners see the production of a gas, which visibly fills up a balloon placed over the neck of a bottle.
Smelly Balloons
Source Institutions
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.
Walking Polygons
Source Institutions
In this activity, learners walk the sides and interior angles of various polygons drawn on the playground. As they do so, learners practice rotating clockwise 180° and 360°.
Jumping to Conclusions
Source Institutions
In this online brain stumper, the bottom half of a series of letters is covered. You may think you know what it says, but remove the black bar to see if you're right.
Quick Questions: Create a Survey

In this activity, learners will conduct an open-ended survey, and then organize and analyze results. What languages does everyone speak? What’s the most common? the least common?
Physics in a Glass: Reversing Arrows
Source Institutions
In this simple activity, learners investigate refraction by placing a picture of an arrow behind a glass of water.
Space Stations: Bones of Contention
Source Institutions
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.
Setting the Scene
Source Institutions
In this activity (on page 2), pairs of learners create an imaginary crime scene. One person leaves the room while the other person moves a few things around.
