Experiment Set Up

This is basically what my experiment looks like. My results will be up in the next 2 posts.

On the 24th of May at 6:08, I started my experiment

(d)2ml white, 4ml black =15.2degreesC

(e)6ml black =15.2degreesC

(f)Yellow cellophane =15.2degreesC

(g)Blue cellophane =15.3degreesC

(h)Red cellophane =15.2degreesC

(i)Control =15.2degreesC

(h)17.5 degrees C

(i)17 degreesC

Climate Graph

This is my fail attempt at scanning a photo. You can probably read the labels though

Research

I will need to research quite a few things, such as:
-electromagnetic waves
-absorption of light
-visible light
-heat energy
-the eye

As I get further into the experiment, the list would probably grow. Fabulous.

Cellophane

Iwill have to make sure my cellophane are all from the same brand so that the chemicals or materials it is made up of stays consistent. I will need to research cellophane if that absorbs heat or not.
I'm pretty sure that I learnt from last year's light topic was that your filter, and in this case the cellophane, will absorb the colour it is made of and reflect the rest. This shows that the cellophane will absorb the heat in some cases, and at other times, reflect.

Absorption goes hand in hand with the heat, the more light it absorbs, the hotter it is.

Method

Before I write out my method, I need to write out how to set up the equipment.

Set up Equipment
1. Paint container with 6mL of white paint
2. Mix 2mL of white paint and 4mL of black paint and paint it on the plastic container
3. Repeat but with 3mL of each colour and paint
4. Repeat with 4mL of white paint and 2mL of black paint
5. Paint the container with 6mL of black paint
6. Wait until all the paint dries, leave it for 24 hours
7. Cover the other jars with yellow, blue and red cellophane.
8. Keep one container clear as the control.
9. Pour 100ml of water into each container.

Method
The equipment was set up and the 9 plastic containers were all set up 10 centimetres away from the light bulb. The temperature of the water in each jar was then measured and recorded. The light bulb was switched on and kept on for 1 hour. The themometer was then placed into each container and the temperature was recorded. This was then repeated 3 more times, one, 2 days later, another 4 days later and the last one 6 days later.
