Watch It Fly
Source Institutions
Learners observe projectile motion by launching wooden balls off of a table top. They set up a rubber-band launcher so that each ball experiences a consistent amount of force.
Sound Charades
Source Institutions
In this game, learners create flash cards with an image on one side (of an animal, for example) and the sound that animal makes on the other.
Better Hair Through Chemistry
Source Institutions
In this activity, learners hook up a hair to a lever system and create a hair hygrometer to measure changes in humidity.
Universal Indicator Rainbow Trout
Source Institutions
In this activity, learners cut out a fish and then "paint" it using universal indicator and acids and bases.
Trading Places: Redox Reactions
Source Institutions
Visitors add drops of copper sulfate solution onto a steel nail. They observe the nail change color from silver to brown as the copper plates onto the nail.
Tops
Source Institutions
In this activity, learners discover that some things only stand up while they are spinning.
Disease Detective
Source Institutions
This activity (on pages 35-43) lets learners analyze a "herd of elk" to detect the spread of a bacterial disease called brucellosis.
Stories in the Sky
Source Institutions
In this activity, learners create their own constellations and star patterns and write a short, descriptive story explaining the significance of their star pattern/constellation.
A Flag for Your Planet
Source Institutions
In this activity, learners design a flag for a chosen or assigned planet. The instructions include information about flags on Earth, and a list of flag references.
Newton's Laws Demonstrations
Source Institutions
In this collection of demonstrations, learners explore Newton's Laws of Motion.
Battleships: Searching Algorithms
Source Institutions
This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.
CD Spinner
Source Institutions
In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.
Building Tetrahedral Kites
Source Institutions
Working in teams of four, learners build tetrahedral kites following specific instructions and using specific materials.
Wheat Evolution: Sedimentation Testing
Source Institutions
In this activity (Page 30 of PDF), learners investigate the evolution of wheat by conducting sedimentation tests on different flours.
A Funny Taste
Source Institutions
In this activity, learners explore the different salinities of various sources of water by taste-testing.
Changing the Density of a Liquid: Adding Salt
Source Institutions
Learners see that a carrot slice sinks in fresh water and floats in saltwater.
How Much Water is in that Cloud?
Source Institutions
In this activity, learners working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.
Classification Line-up
Source Institutions
This activity was designed for blind learners, but all types of learners can use it to organize an interactive model for learning the classification system (taxonomy) of living things.
Mix and Match
Source Institutions
In this activity (7th activity on the page), learners use their sense of hearing to find a "sound match." Learners shake containers filled with items like dry seeds, sand, beans, etc.
Chromatography Can Separate!
Source Institutions
In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.
