Science: Light ( Overall thoughts) and an easy experiment!

This term I have really enjoyed learning about light and the small

piece on shadows. In one of the first lessons I really liked the laser pen.

I found it interesting how you could see the beam running in a straight

line safely .I've had two favourite lessons overall though. One of them was when we looked at

lighting effects and made our own. The other was when we were doing rainbows and looking at refraction. In that same lesson I liked it when we were mixing light.

Easy experiment!

Generating electricity from salt water.

You will need:

1 Battery holder

1 9v battery

1 light bulb

1 bottle of water

Table salt

3 wires

Aluminum foil

Duct tape

A teaspoon

First, you need to put the battery into its holder.

Next, take the water and the salt and mix them together.

After that, take your foil and make a tube and put it in the water.

Now for the wires. Take one wire and connect it to the battery and the aluminium tube.Then grab another wire and attach it to the battery and light bulb. And finally attach the 3rd wire to the bulb and put it in the water.

You will now be generating electricity.

WARNING

Remenber to be safe!
