Rotating Light
Source Institutions
In this activity, learners explore what happens when polarized white light passes through a sugar solution.
Touch the Spring (Lightbulb)
Source Institutions
In this activity, a lightbulb is placed in front of a concave mirror. The actual lightbulb is not visible to the viewer, but the viewer can see the mirror image of the lightbulb formed in space.
Running in Circles
Source Institutions
In this group activity, learners use some common objects and work together to simulate the Coriolis effect. During the challenge, learners make predictions and test different scenarios.
Scaling an Atom
Source Institutions
In this activity, learners make a scale model of an atom to see how big or how small an atom is compared to its nucleus. Learners will realize that most of matter is just empty space!
Pi Graph
Source Institutions
In this activity, learners use a straight line to learn about circles. Learners measure and record the diameter and circumference of different sized cylindrical objects on a chart.
Glow Up
Source Institutions
In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.
CD Air Puck
Source Institutions
In this activity, learners will use a compact disc to build an air puck that can glide across a smooth tabletop. The puck glides with almost no friction on a cushion of air escaping from a balloon.
Stability of Egg White Foams
Source Institutions
In this chemistry meets cooking activity, learners compare the stability of egg white foams with various additives.
Piezoelectric One-Way Remote
Source Institutions
In this activity, learners construct a device out of a piezoelectric igniter, like those used as barbecue lighters.
Rutherford Roller
Source Institutions
In this activity, learners make a black box device that serves as an excellent analogy to Rutherford's famous experiment in which he deduced the existence of the atomic nucleus.
Cake by Conduction
Source Institutions
In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.
Sliding Gray Step
Source Institutions
How can you make one shade of gray look like two? By putting it against two different color backgrounds! This activity allows learners to perform this sleight of hand very easily.
Slide Projector Activities
Source Institutions
This resource contains several mini-explorations using a slide projector as a light source to investigate light and the properties of images.
Simple Spinner
Source Institutions
In this activity, learners create a tiny electric, motorized dancer. Learners use the interactions of magnetism and electric current to make a wire spin, while displaying the Lorentz Force in action.
CD Spectrometer
Source Institutions
In this activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.
Charge and Carry
Source Institutions
In this activity about electricity, learners produce a spark that they can feel, see, and hear. Learners rub a Styrofoam plate with wool to give it an electric charge.
Greeting Card Boxes
Source Institutions
In this activity, learners make cool boxes out of old (or new) greeting cards or postcards.
Magnetic Free Fall
Source Institutions
In this activity, learners use a pencil, magnets, and mat board to illustrate Newton's Second Law.
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).
Rotating String Shapes
Source Institutions
In this group activity, learners make multi-sided polygons with string.
