Helicopters
Source Institutions
In this activity, learners will observe how air interacts with a paper helicopter. Learners will test different variables of weight, size, and shape.
Backyard Graphing
Source Institutions
In this math activity, learners will create a scale diagram of their backyard or other outdoor area on graph paper.
Bridge Building
Source Institutions
This is a quick activity (on page 2 of the PDF under Hockey Sticks Activity) about how the arrangement of carbon atoms determines carbon's different properties.
2-Liter Landfill
Source Institutions
In this activity, learners gain a better understanding of how household/school waste breaks down in a landfill. Learners collect trash and then create miniature landfills in 2-liter bottles.
Musical Coathanger
Source Institutions
In this activity, learners turn an ordinary metal coat-hanger into a (very quiet) musical instrument.
Build A Hydrometer
Source Institutions
In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.
Whirling Watcher: Make a Stroboscope
Source Institutions
In this activity, learners make a stroboscope--a spinning disk with slits around the edge that you look through.
Sock Garden
Source Institutions
In this activity (located in the middle of the page), learners start a garden by planting their socks!
Look Mom, No Wings!
Source Institutions
In this activity about flight, learners explore how high they can jump. Learners dip their finger in ink or dirt, then jump as high as they can and mark paper attached to the wall.
How the Mushroom Got Its Spots
Source Institutions
In this activity (p.26 of PDF), learners discover why mushrooms have spots. Learners use a balloon, toilet paper, and water to simulate what happens as mushrooms grow.
Dissolving a Substance in Different Liquids
Source Institutions
In this activity, learners make colored sugar and add it to water, alcohol, and oil to discover some interesting differences in dissolving.
Dancing Cereal
Source Institutions
In this quick activity (on page 2 of the PDF under GPS: Body Electricity Activity), learners will observe how dry breakfast cereal appears to dance when it gets close to a balloon charged with static
Size it Up
Source Institutions
Learners investigate why the Sun and Moon appear the same size in the sky even though the Sun is over 400 times larger in diameter.
Drip, Drop, Drip, Drop
Source Institutions
In this math lesson, learners design an experiment to model a leaky faucet and determine the amount of water wasted due to the leak.
Hot Stuff!: Investigation #3
Learners test two jars of ice water, one covered and one open, for changes in temperature. After placing the jars in the sun, learners discover that the covered jar cools down more slowly.
Do Sweat It!
Source Institutions
In this activity, learners explore why humans sweat. Learners compare the effects of heat on a balloon filled with air and a balloon filled water.
Exploring Earth: Paper Mountains
Source Institutions
In this activity, learners explore in what ways the shape of the land and the pull of gravity influence how water moves over Earth.
Squeezing Pictures Into Codes
Source Institutions
In this activity, learners will explore how computers represent pictures using pixels.
Squeeze the Stream
Source Institutions
In this activity related to flight, learners build a tiny stream channel to investigate how fluids (air and water) change speed as they flow between and around objects.
Seeing Is Believing
Source Institutions
This activity is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Learners look through two cups with small holes in them to simulate what it'
