We grew some cress in box with a lid on it, that had one small hole for light. The result: a beautiful example of phototropism, plants growing and moving towards a source of light.

This is a great activity to try at home with the kids.

One Easy Way To Test Batteries 

Used batteries bounce and tend to fall down when dropped. New batteries do not bounce as much and tend to stay standing.

Not all shadows are black. The Colored Shadows exhibit is a discovery of the colors hidden in white light. Red, green and blue spotlights shine on a wall. The wall is white because red, blue and green light combine to make white light. These colors are often called the additive primary colors. As you walk (or dance) between the lights and the wall, your body casts three different shadows. 

This is a homopolar motor.

It’s really easy to experiment with at home. It is driven by the Lorentz force - the force which is exerted by a magnetic field on a moving electric charge. When a battery is placed on top of a magnet, and a wire then connects the top of the battery back down to the magnet, the circuit is complete.

Students in our Summer Schools were making these the other day. This one won the ‘most creative design’ competition <3

We love these Silly Science Experiments For Kids!

The elements carbon, hydrogen, oxygen, and nitrogen - all crucial to life - are found in roughly the same proportions in comets and human beings. 

A magnet falling through a cylindrical hollow copper pipe. The magnets slows down in the center because as the metal falls it induces an emf in circular direction in the copper which in turn generates its own magnetic field under the action of Faraday’ law of electromagnetics but opposite in direction as determined by the Lenz’s law. This induces opposite magnetic field interacts with the magnet and tries to slow it down. Cool haa !!

Want to make a rubber egg? Your students do.

Materials: 1. A D size battery 2. Paper clips 3. 3 feet of thin coated copper wire 4. A 3 inch large iron nail Steps: 1. First, leave 8 inches of wire at one end and wrap most of the rest of the wire on the nail ( do not overlap the wires). 2. Next, leave 8 inches of wire at the other end of the nail. 3. Then, remove an inch of the plastic coating from both ends of the wire and attach one end of the wire to one end of the battery and the other wire to the other end of the battery. 4. Finally, put the nail near the paper clips and it should pick them up! Lesson: Magnets that cannot be turned off like ones on our refrigerators are called permanent magnets. Since the magnet we made can be turned off and on, it is known as an electromagnet. They run on electricity and are only magnetic when the electricity is flowing through the wires, which has the molecules in the nail attract to the metal paper clips.
