One In The Hand
Source Institutions
In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.
Invisible Sunblock
Source Institutions
In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.
Bernoulli Obstacle Course
Source Institutions
In this activity, learners create their own obstacle course based on Bernoulli's Principle and try to get a floating ball from the start of their course to the finish line.
Change in Temperature: Endothermic Reaction
Source Institutions
Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.
Shrinky Dinks
Source Institutions
Heat makes some materials expand, and it makes others shrink.
Temperature Affects the Solubility of Gases
Source Institutions
In this activity, learners heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water.
Animals in a Grassland
Source Institutions
In this outdoor, warm weather activity, learners use sweepnets to search a grassy area such as a large lawn or field, collecting small animals to find as many different kinds of animals as possible.
Upside-Down Town
Source Institutions
In this activity, learners explore ray optics. Learners discover that they can use a magnifying glass to create an upside-down image.
How Many In a Minute
Source Institutions
In this activity, learners will keep track of how much they can do in one minute. Instructors can pick something everyone will do for a minute, such as jumping up and down or drawing stars.
Mission Insignia
Source Institutions
In this science/art activity, learners create an insignia or emblem for a planet exploration mission.
Feed the Birds
Source Institutions
Learners construct a bird feeder from re-used materials. After hanging their feeder, they keep a journal about what birds visit the feeder.
CD Greenhouse
Source Institutions
In this activity, learners plant seeds and watch them sprout and grow inside a CD case.
Piles of Paper: Estimate Paper Use
Source Institutions
In this activity, learners keep track of how much paper the group uses in a week. Build awareness of paper waste, while strengthening measurement and estimation skills.
River Catcher
Source Institutions
In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.
Learning the Land
Source Institutions
In this activity, learners will take a step back and learn the history of the land they live on, and the people who used to live on it.
Caller ID: The Frog - and Toad! - Mating Game
Source Institutions
This activity is a sensory experience that recreates the sounds of a pond at night.
Dueling Dice
Source Institutions
In this activity, learners explore probability with dice.
Trash Traits
Source Institutions
In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.
Toasty Wind
Source Institutions
In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.
Corner Reflector
Source Institutions
In this optics/mathematics activity, learners use two hinged mirrors to create a kaleidoscope that shows multiple images of an object.
