Snow

I think this would be something fun to have in a classroom - especially in Hawaii. It could be used when we cover the forms of matter.

Volcano

In one of the class presentations, we got to make a volcano out of a jar with baking soda and water (with some detergent). I saw this online at Amazon.com for less than $10.

Laser Pointer

Laser pointers are a good resource to use to look at the different characteristics of light and what mediums light can or cannot pass through. It is also really good to use for testing what mediums reflect or refract light.

Rocket Balloons

These balloons are good to use for teaching the concepts of "Force" and "Motion" (Newton's 3rd law of motion).

Electromagnet

This electromagnets uses batteries to convert electricity to magnetic energy. This can be found here:

Magnets

We used magnets in class for a few presentations. I really like the magnets with the North and South marked on them. I can purchase some here:

Butterfly Garden

We did not get to use the butterfly garden that was in the classroom (but we did have some catepillars that turned into butterflies). This is something I would like to have in my classroom someday.

Volcano

In one of the class presentations, we got to make a volcano out of a jar with baking soda and water (with some detergent). I saw this online at Amazon.com for less than $10.

Food Chain Story

I really liked the idea of using this book to help introduce the food chain into a lesson and that is why I am putting it on my science wikipedia.

Tornado Tube

The tornado tube is a contraption that allows two 2 liter bottles to be screwed onto it from both ends. One bottle is usually filled about 3/4 full with water and then turned upside down so that the water drains into the empty bottle. When the draining takes place, it forms a tornado within the bottle. A lighter (in weight) colored liquid could be added to the water for more visual effect.

Diving Ball

This diving ball demonstrates the submarine theory and Archimedes' principle. When air is drawn out of the ball with the syringe, a vacuum is created. Water enters the ball through the nut in the bottom of the ball causing the ball to sink. Then, by slowly filling the ball with air the water is forced out and the ball rises.

Pulse Glass

A pulse glass is a completed enclosed container that contains a liquid that boils at a lower temperature than water. When your body temperature comes in contact with the end of the glass that contains the liquid, the liquid will rise against gravity in a series of bubbles or pulses.

Energy Ball

This is a small ball that has two small metal electrodes. When the electrodes are touched simultaneously, the ball lights up and makes a sound. This is done when the electrodes are touched with anything that can conduct or carry electrodes. It is commonly used to demonstrate how open and closed circuits work.
