The Squeeze Box
Source Institutions
In this geology activity learners build a "squeeze box," which allows them to compress layers of sediment. This is a great way to investigate folding and faulting in the Earth.
Pocket Change: Math and Coin Toss
Source Institutions
In this activity, learners will play a coin toss game where the highest total wins. Combine coin recognition, addition, and probability with a game learners can play on their own.
Radioactive-Decay Model: Substitute coins for radiation
Source Institutions
Get a roll of pennies, throw them on the ground, then remove those that only show tails, and repeat with the ones left over.
Active Touch
Source Institutions
In this activity (14th activity on the page) about the sense of touch, learners examine if it is easier or harder to identify an object if they move their hands over it.
No Saliva, No Taste?
Source Institutions
In this activity (4th activity on the page), learners test to see if saliva is necessary for food to have taste.
Guesswork
Source Institutions
In this number puzzle/trick, learner #1 thinks of a number between 1 and 63. Learner #2 shows learner #1 six cards and asks them whether the cards contain their number.
Patterns in Pixels
Source Institutions
This activity (page 2) draws upon a familiar, computer-based concept related to visual resolution: pixilation.
Pepper Scatter
Source Institutions
In this quick activity, learners break the tension that happens when water develops a "skin." Learners use water, pepper and some soap to discover the wonders of surface tension—the force that attract
Dunk and Flip
Source Institutions
Learners complete two simple experiments to prove the existence of air and air pressure which surround us.
Fun With Stress
Source Institutions
In this activity, learners complete simple exercises to investigate the relationship between force, area and pressure and their effects on materials.
Exploring the Universe: Imagining Life
Source Institutions
“Exploring the Universe: Imagining Life” is a hands-on activity in which visitors imagine and draw an extreme environment beyond Earth, then invent a living thing that could thrive in it.
Exploring the Solar System: Moonquakes
Source Institutions
In this activity, learners sort different natural phenomena into categories (they occur on Earth, on the Moon, or on both), and then model how energy moves during a quake using spring toys.
Hoop Glider
Source Institutions
In this activity, learners will experiment with the physics of flight by making a gliding contraption with strange looking wings. The activity explores flight with connections to the natural world.
Discovery Time: Trees
Source Institutions
In this activity, young learners (2 years and up) explore tree structure and biology. Tree products are explored by painitng with fruit.
Stadium Seat Science
Source Institutions
Take the two-straw challenge and discover how pressure affects vacuums! In this activity, learners experiment with drinking through one and two straws, comparing the amount of liquid they can drink.
Balloon in a Bottle
Source Institutions
In this physics activity (page 3 of the PDF), learners will see firsthand that air takes up space and has pressure by attempting to inflate a balloon inside of a bottle.
The Nose Knows
Source Institutions
In this activity (2nd activity on the page), learners explore how the nose is responsible for part of the flavor we taste in food.
Stack-o-Pennies Shop
Source Institutions
In this math activity, learners pretend there is a special store that lets you pay for toys by their height in pennies.
How Many Pennies?
Source Institutions
In this math activity, learners pretend there is a special store that lets you pay for toys by their weight in pennies.
Go with the Flow
Source Institutions
In this quick and easy activity and/or demonstration, learners use two empty soda cans to illustrate Bernoulli's principle.
