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.
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
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.
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
Gravity and Falling
Source Institutions
This fun and simple hands-on astronomy activity lets learners experiment with a bucket, stretchy fabric, marbles, and weights to discover some basics about gravity.
Wilberforce Pendulum
Source Institutions
In this activity, learners build a Wilberforce Pendulum, a special coupled pendulum in which energy is transferred between two modes of vibration, longitudinal ("bounce') and torsional ("twist"), on a
Dollar Bill Grab
Source Institutions
In this demonstration, learners observe as two cola bottles and a dollar bill are arranged in a specific order: one bottle, upside down and filled with water, is placed on top of another bottle, with
Rubber Band newton Scale
Source Institutions
In this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).
Downhill Race
Source Institutions
In this activity, learners explore how two cylinders that look the same may roll down a ramp at different rates.
Balancing Act
Source Institutions
In this physics activity (page 6 of the PDF), learners will build a class 1 lever and hypothesize and test the distances two objects need to be placed from the fulcrum in order to balance.
Spring Scale Engineering
Source Institutions
In this activity, learners explore how spring scales work and how they are used for non-exact weight measurement.
Turning the Air Upside Down: Spinning Snakes
Learners color and cut out a spiral-shaped snake. When they hang their snake over a radiator, the snake spins.
Lift Experiment
Source Institutions
In this experiment, learners investigate how the size of a wing affects lift. Learners count the number of pennies an egg crate plane wing can hold until the plane will no longer fly.
Statue Display Tower
Source Institutions
In this activity, learners design, build, test and redesign a display tower that will meet a specific set of criteria and constraints.
