Make electromagnetic eddy currents evident with this demonstration. You will need to gather a few materials from the local hardware store and a strong neodymium magnet, but the visual value is well worthwhile.

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....

Using flexible mirror-like paper, physical scientists experiment with images produced by curving it and looking into its reflective surface. They find that concave mirrors cause reflected light waves to cross and actually flip the image...

Hang a strip of foil on a stand and form a loop out of it. Then attach the clips of a battery-operated circuit to the loop to see its sides repel each other. This simple demonstration is applicable and easy to add to your lecture on...

If you are attracted to activities dealing with diamagnetism, here is a rare find that you will appreciate. With a neodymium magnet and a few common materials, move a pair of juicy grapes without touching them. Though the fruit is...

What is a network? Kids model one to find out that it is a series of paths that something can travel along. Take them outdoors to get in touch with this technology topic; make it an introductory lesson in your STEM unit when teaching...

Is it a bird? Is it a plane? It's super student! Physical science stars can fly during a unit on light as they see the reflection of one leg in a mirror, behind which the other holds them up. 

A site based on remembering Nagasaki before, during, and after the bombing. Many pictures and accounts can be accessed by clicking on the picture the page.

This site is on the science and art of skateboard design, including equipment, tricks, glossary of terms, and a live webcast of a skateboard performance.

This lesson plan is a great way to observe the flow of water. Kids can do this experiment at home by following this easy procedure, complete with pictures.

What colors do you see in a bubble? Why do you see colors in a bubble? Use this site to find out the answer to these questions with this easy experiment.

Children can look around corners with this homemade periscope. Great instructions at this Exploratorium site on how to build a periscope.

Students can make ooze and learn about different qualifications of matter. An easy procedure is provided to make gooey ooze that you can play with when you are done.

By making oil float on water--with the help of other ingredients--students can create a lava-lite effect.

Students create their own airplane using straws and other materials and learn the principles of aerodynamics.

Students create a blimp and then experiment with the design to improve its aerodynamics.

Students can experiment with a home-made helicopter that lets them change the blades to see how real aerodynamics work.

At this site students will use origami to fold a paper airplane that fly better than the classic dart airplane.

At this site students can read about how frogs camouflage to avoid predators. There is an interactive exhibit too! (Must have the Shockwave plug-in to see animation.)

An optical illusion created using Leonardo's well-known portrait of the Mona Lisa serves as source material for an exercise in perception.

Students can experiment at home with expanding balloons, dancing raisins, and pop cans that have been shaken up.

Students can make a empty soda can roll with an electrically charged balloon.

An optical illusion that demonstrates the effect of eye movement on perception.
