Hurumanu - Solar Energy

Solar Energy

Aim: To find out which colour attracts the suns heat.

Hypothesis: 

I think silver will attract the sun because its the colour of metal and metal always gets hot when its in the sun.

Materials:

1.  White A4 Paper
2.  White Plastic Cup  
3.  Clear Plastic Cup 
4.  Tin foil Plastic cup
5. Black Plastic 
6.  Thermometer
7.  Heat Lamp
8. Water 

Step

1. Collect materials from the teacher. 

2. Set up the Cups:

- Plastic cup covered with the black plastic 

- A Tin foil Cup

- White cup 

3. Set up the Heat Lamp.

4. Add the water into each cup.

5. Start recording the temperatures of the water.

Findings:

Time	Cup 1 White	Cup 2 Black	Cup 3 Tinfoil
0	16'c	16'c	16'c
15	19.1'c	19'c	20'c
30	25'c	27'c	26'c
45	20'c	24.5'c	22.5'c

This is a photo of our experiment that my group are currently still recording the temperatures of the water in them.

Conclusion:

Today in science we have started on a new experiment called Solar Energy. I was in a group of four with Janel, Sierra and Rowina. We had to collect all of the materials that was needed for the experiment and had to record the temperatures of each of the cups. A tin foil cup, a white cup and a clear plastic cup covered with the black plastic.
Overall is was a great experiment and lesson learning about solar energy.
