## Density

## conduct

Conduct means to carry something over to something else. I don't mean pick it up and

carry it to another place. Metal for example, it's a great conducter of electricity!

Examples of conducters of electricity:

• metal
• copper
• brass

Electricity isn't the only thing that can be conducted, Heat can also be conducted, and metal is a great conducter of that to!

This iPhone charger conducts electricity from the wall to the phone. It's covered in rubber that makes it okay to touch, but under the rubber there is just a wire and if you touched it you'd get electricuded!

## insulate

Insulate means to keep in heat.

Like when you have a cup of tea in a glass cup

the glass keeps your tea warm because it doesn't

let the tea's heat out.

This boys jacket is insulating his body heat.

## Solubility

If something is soluble it means it can dissolve. But what does dissolve mean? It's kind of like some thing dissapears in water. Like salt, for example, it dissolves when you put it in water.
