Physics Tug of War
Learners set up books with rubber bands stretched between the books. When two identical books are stretched apart and released, they move back toward each other an equal distance.
Lifting with Levers!
Source Institutions
In this fun hands-on activity learners explore a simple machine: the lever. What happens to a load when you multiply the length of a lever? Find out here!
Heavyweight Champion: Jupiter
Source Institutions
In this activity, learners confront their perceptions of gravity in the solar system.
Chew that Gum
Source Institutions
In this quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.
The Pull of the Planets
Source Institutions
In this activity, learners model the gravitational fields of planets on a flexible surface.
Dunking the Planets
Source Institutions
In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.
Geometry and Algebra: The Future Flight Equation
Source Institutions
In this activity, learners discover how NASA engineers develop experimental aircraft.
Tired Weight
Source Institutions
Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.
Space Stations: Beans in Space
Source Institutions
In this activity, learners perform 20 arm curls with cans that simulate the weight of beans on Earth versus the weights of the same number of beans on the Moon and in space.
Hanging Around
Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.
Egg Bungee Jump
Source Institutions
In this activity, learners design a bungee jump for an egg using nylon stockings.
Clay Beams and Columns
Source Institutions
In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.
Big Things Come in Little Packages
Source Institutions
As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.
A Question of Balance
Source Institutions
In this activity, learners explore how engineers use scales and measures when designing a manufacturing process to ensure that final products are uniform in weight or count.
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.
Going Green
Source Institutions
In this activity, learners conduct a waste audit and use their findings to implement a plan for reducing trash.
Moving Model Glacier
Source Institutions
In this goopy activity (page 2 of PDF under GPS: Glaciers Activity), learners will model glacial movement with “gak,” a white glue and liquid starch mixture.
Swing in Time
Learners build and investigate pendulums of different lengths. They discover that the longer the string of the pendulum, the longer the time it takes to swing.
Bend That Bar
Learners play the role of materials engineers as they test the flexibility of different materials.
