Space Stations: Bones of Contention
Source Institutions
In this activity, learners make models representing bones on Earth and bones that have been in space. They discover what happens to bones without proper exercise and nutrition.
Enhanced Water Taste Test
Learners conduct a "blind" taste-test of several types of enhanced or fitness water drinking water that has commercially added substances like vitamins, sugars, or herbs.
Bouncing Balloons
Source Institutions
In this sports-themed engineering activity, learners create super bouncy balls out of balloons. Learners brainstorm, test their designs, and share results.
What Counts in Bounce
Source Institutions
In this activity learners compare the bounciness of warm and cold racquetballs to see if temperature makes a difference in how well they bounce.
Twirling Rope Frequency
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Double Dutch), learners will stand twelve feet apart swinging a rope at the slowest tempo possible while someone uses a stopwatch to record
Kites
Source Institutions
In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.
"Baseketball": A Physicist Party Trick
Source Institutions
This trick from Exploratorium physicist Paul Doherty lets you add together the bounces of two balls and send one ball flying.
Space Stations: Follow the Bouncing Ball!
Source Institutions
In this activity, learners predict whether a ball on Earth or a ball on the Moon bounces higher when dropped and why.
Cryptographic Protocols: The Peruvian Coin Flip
Source Institutions
This activity about cryptographic techniques illustrates how to accomplish a simple, but nevertheless seemingly impossible task—making a fair, random choice by flipping a coin between two people who d
Frog Olympics
Source Institutions
Did you know that a bullfrog can jump a distance of 10 times its body length? Learn more about nature's most acrobatic amphibian, the frog, through this set of short, hands-on activities.
Take It in Stride
Source Institutions
In this health and fitness activity, learners focus on the importance of daily physical activity, specifically walking.
Pop Fly
Source Institutions
In this design challenge activity, learners invent a way to send a Ping-Pong ball flying high enough to catch it - like football with a twist!
