Penny Battery
Source Institutions
In this activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.
Space Elevator
Source Institutions
In this activity, learners imagine what the world might look like if we could build an elevator to space!
Bernoulli Brain Teasers
Source Institutions
In this activity related to flight, learners conduct two simple tests to explore how lift works.
Electroscope
Source Institutions
In this activity about electricity, learners suspend pieces of tape from a straw to construct an electroscope, a device that detects an electrical charge.
Earth and Mars
Source Institutions
Based on color photographic images, learners compare geological features on Earth and Mars to understand similarities and differences between the two planets, and consider the forces that created land
Flip
Source Institutions
In this amazingly simple physics activity (page 5 of the PDF), learners will explore how exerting a force on an object can give it kinetic energy and momentum.
Sleep Patterns
Source Institutions
In this activity about sleep rhythms (on page 21 of the PDF), learners will collect data about their own sleep cycles and use a fraction wheel to examine their data.
Three Bean Salads
Source Institutions
This game teaches ratio and proportion by having learners make "salads" that combine three types of beans in different combinations.
Special Effects: Titanic and Beyond
Source Institutions
In this activity, learners investigate how geometry plays a role in perspective.
Balloon Surprise
Source Institutions
In this activity, learners discover a trick to release the air out of a balloon without popping it.
Weather Stations: Winds
Source Institutions
In this activity, learners use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. Learners discover that convection drives wind on Jupiter and on Earth.
Xenosmilus
Source Institutions
Learners imagine they are paleontologists in Florida, where they find (remove from envelope) paper "fossils" of some unknown creature, only a few at a time.
Shrinking Coin
Source Institutions
In this demonstration, learners attempt to get a large coin through a small hole, the size of a smaller coin.
Test the Finger Wrinkle Hypothesis
Source Institutions
Learners create a tool to measure how well they grip a wet object when their fingers are smooth versus wrinkly. Are smooth or wrinkly fingers better at holding on to the object?
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.
Endangered!
Source Institutions
While playing a game, learners discover how the Endangered Species Act works in the United States. Learners move along a game board by answering questions correctly.
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.
