Sound & Light  
A collection of activities that explore basic concepts dealing with sound and light. They are written for the 4-6th grade level.
Float or Sink  
It is wrong to think that light things float, while heavy things sink. For example, a heavy log will float down a river, but a light grain of sand will sink. How heavy an object is does have something to do with whether it will float or sink. But there is more to the story. In this activity students investigate what causes an object to float or sink.

Batteries ? Energy to Go  
Students create a simple circuit by connecting a bulb to a battery. Connecting the bulb and wires to the ends of the battery gives the electrons a path to travel from one metal to the other. The battery produces electricity used to light the bulb. ,

A State Debate  
It?s not always so easy to say definitely that a substance is a solid, liquid, or gas. Some materials, like cornstarch mixed with ,water, can act more like a solid when treated a certain way and more like a liquid when treated a different way. Shaving ,cream seems to have an unusual state because it is a liquid soap with a lot of gas bubbles mixed in it. The gas makes it so ,thick and frothy that it keeps its shape and supports light objects like a solid. When you let the liquid from shaving cream evaporate, all that's left is the very light and thin solid. In this activity, students explore some characteristics of solids, liquids and gases.

Secret Circuits  
Students make a circuit detector by connecting a light bulb to a battery and a wire. , The circuit detector is actually most of a circuit but not all. There needs to be a way for electricity to flow from the end of the wire to the bottom of the bulb to complete the circuit. Students use the detector to uncover hidden circuits prepared by their teacher. ,
Water Walkers  
In this activity, students explore surface tension in water. Some insects literally walk on water. They can do this because of their light weight and broad support. The surface tension in the water is great enough to support the insects. Students in this activity try to fashion their own water walkers made from aluminum foil.

Batteries and Bulbs  
In this activity, students learn what it takes to make a complete electric circuit. They are given the challenge of making a flashlight bulb light up, given a wire, bulb and a battery. To make a complete circuit, students connect the battery, the wire, and the bulb so that electricity will have a path to flow from the bottom of the battery, through the wire, into the little wire on the side of the bulb, up that wire, through the filament, down the other bulb wire to the bottom of the bulb base and to the other end of the battery. , ,
