Gummy Shapes
Source Institutions
In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.
Spider Glider
Source Institutions
In this fun activity about spiders, learners build and design a spider from cardstock, straw, string, and pipe cleaners.
Eye Spy
Source Institutions
This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.
You Can't Take It With You
Source Institutions
This activity models the necessary balance of creating power and cleaning up its associated waste. Learners participate in a game where they attempt to move forward toward a goal.
Bark Beetle Infestation Investigation: Estimation and Pheromones
Source Institutions
This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.
What's in the Bag?
Source Institutions
In this activity, young learners use their sense of touch rather than sight to identify a mystery object in a bag. Learners take turns acting as "peekers" and "sensers" throughout the game.
Glass and Mirrors: An Inside Look at Telescopes
Source Institutions
This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.
Moving Molecules!
Source Institutions
In this activity about molecular diffusion (located on page 2 of the PDF under Nanosilver Activity), learners will make predictions and move molecules of iodine through a seemingly solid plastic sandw
Power Up!
Source Institutions
In this online game, learners must purchase power plants for their city.
Hanford at the Half-Life Radiation Calculator
Source Institutions
This quiz lets you estimate your annual radiation exposure.
What's the Buzz?
Source Institutions
In this activity, learners construct a playable kazoo from inexpensive materials. They will experience how vibration creates sound waves and music.
Mint Your Own Coin
Source Institutions
Coins are everyday objects which tell a lot about the people who use them.
Globe at Night
Source Institutions
In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.
Motion Picture
Source Institutions
During this hands-on activity, learners are briefly exposed to moviemaking and animation, when they create their own thaumatropes.
Screaming String Thing
Source Institutions
In this simple and fun activity, learners discover the relationship between vibration and sound by making a squeaky toy instrument out of simple household materials.
Polarized Light Mosaic
Source Institutions
In this activity, learners use transparent tape and polarizing material to create and project beautifully colored patterns reminiscent of abstract or geometric stained glass windows--no glass required
Shadow Puppets
Source Institutions
In this activity, learners explore color, light and shadow by creating their own puppets to hold in front of a light source.
The Carbon Cycle: Carbon Tracker
Source Institutions
In this activity, learners play NOAA's Carbon Tracker game and discover ways to keep track of carbon dioxide and other greenhouse gases in the world.
Cleaning Air with Balloons
Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.
Make a Wire Critter That Can Walk on Water
Source Institutions
In this activity, learners make water-walking critters using thin wire, and then test how many paper clips these critters can carry without sinking.
