Fly a Hot-Air Balloon
Source Institutions
Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.
Skateboard Disaster
Learners examine collisions between two skateboards carrying different masses. They learn about conservation of momentum in collisions.
Burn a Peanut
Source Institutions
In this activity, learners burn a peanut, which produces a flame that can be used to boil away water and count the calories contained in the peanut.
Fast Rusting
Source Institutions
In this activity, learners conduct an experiment to find out if steel wool will weigh more or less when it is burned. Learners will explore the effects of oxidation and rusting on the steel wool.
Motorized Balancing Toy
Source Institutions
In this activity, learners build a toy that flies in circles. This activity introduces learners to center of mass, torque, and rotational motion.
Buoyancy Bulls-Eye
Source Institutions
In this hands-on activity, learners will construct a scuba diver that can float in order to explore how sea creatures stay neutrally buoyant in the ocean and to see what kinds of forces might be influ
Inverted Bottles
Source Institutions
In this activity, learners investigate convection by using food coloring and water of different temperatures.
Eggshell Inertia
Source Institutions
In this physics activity (page 14 of the PDF), learners gain a better understanding of how friction and mass affect objects by comparing the rotational inertia of raw and hard-boiled eggs.
Volume, Mass, and Density Boxes
Source Institutions
This activity was designed for blind learners, but all types of learners can utilize it to investigate volume, mass, and density.
Balancing Stick
Source Institutions
In this quick and simple activity, learners explore how the distribution of the mass of an object determines the position of its center of gravity, its angular momentum, and your ability to balance it
Make a Balance / Scale
Source Institutions
In this activity, learners create a kind of balance device using a wire coat hanger, some string, and paper cups.
Airplane Wing Investigation
Source Institutions
This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.
Light as Air
Source Institutions
In this physics activity (page 6 of the PDF), learners will demonstrate air has weight by comparing an inflated balloon to a deflated one.
Heavy or Light
Source Institutions
In this activity, learners explore a scale by comparing objects, which look similar but have different weights. Learners predict and then measure the weights of various objects using a scale.
Stretching Wires
Source Institutions
In this activity, learners determine the elastic and plastic properties of different types of metal wires.
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.
Build a Raft
Source Institutions
In this activity, learners explore density and buoyancy as they design and construct rafts.
Loony Balloons
Source Institutions
In this activity, learners investigate how changing the center of gravity of a balloon affects how it travels. Learners fill a balloon with a little bit of water and insert into an empty balloon.
Springs and Stomachs
Source Institutions
In this demonstration, learners investigate mass, gravity, and acceleration by dropping a wooden bar with a balloon attached to its underside, a mass suspended from it by rubber bands, and a sharp-poi
M&M® Model of the Atom: Edible Subatomic Particles
Source Institutions
In this activity, learners use colored candy to represent subatomic particles and make a model of an atom (Bohr model).
