Magnetic Suction
Drive an electric current through a coil of wire and show how it can pull a nail right into its core. This vivid demonstration exhibits the electromagnetic field. Consider also showing your class a few of the devices that make use of...
Exploratorium
Hot Spot
Not only does a concave mirror focus light waves, it can also concentrate infrared radiation into a hot spot. If you have a small electric heater and such a mirror, demonstrate this for your physical science class.
Exploratorium
Geyser
Although it requires a little extra preparation the first time you use this geyser demonstration, it can be used repeatedly once it has been constructed. This demonstration is useful in showcasing how heat leads to increased pressure and...
Exploratorium
Corner Reflector
If you set up a triad of mirrors into a corner figuration, they act as a kaleidoscope, bouncing light waves back and forth indefinitely, changing the light that your eyes perceive. Although the materials required are very specific and...
Exploratorium
Water Sphere Lens
With a Florence flask or fishbowl, make a double convex lens and use it to examine an image. Because of the refraction, the image will be inverted. A simple explanation is provided here for you to share with your class as they...
Exploratorium
Magnetic Pendulums
Passing a copper wire coil through a magnetic field influences another coil to also sway. It is with this demonstration that you can teach your physical science fans about electromagnetism. Note that the assembly requires about an hour,...
Exploratorium
Whack-a-Stack
Go wild as you hit a stack of wooden blocks to demonstrate Newton's first and second laws of motion. The blocks at the top of the stack stay put as you knock one at a time out of the bottom. Note, however, that you will need to visit a...
Exploratorium
Far Out Corners
Construct a three-dimensional optical illusion when your class is exploring vision and how the eye and brain work together. Three concave corners are mounted inside of a black box, but as a light is shined upon them, they appear to be...
Exploratorium
The Dipping Bird
If you have or want to order the dipping bird demonstration, it is useful for showing how evaporation and changes in the pressure of a closed system cause cyclical motion. After teaching about pressure, consider setting this little guy...
Exploratorium
Depth Spinner
Put a new twist on your collection of optical illusion activities. Affix the linked printable spiral to a drill, record player, or some other rotating tool. Have learners stare at the spinning disk for only 15 seconds and then look away....

Bubble Suspension
Create a cushion of carbon dioxide gas to float some soap bubbles on. Many concepts can be demonstrated through this activity:
Carbon dioxide gas is more dense than air
Bubbles are semipermeable, allowing only carbon dioxide to diffuse...
