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

Hypothesis: I think the colour silver will attract the sun. 

Materials:

1. white cup 
2. white paper 
3. black plastic
4. 2 clear cups
5. tin foil  
6. heat lamp 
7. thermometer

Steps

1. Collect all of the materials 
2. Put the white paper on the table
3. Put the white cup on top of the paper
4. Put black plastic on the table next to the white paper 
5. Put the cup on the black plastic cover 
6. Put the clear cup in the centre of the plastic
7. Put the tin foil next to the black plastic 
8. Cover the clear cup with tin foil
9. Put the heat lamp in front of the cups

1.  Findings:

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

Conclusion

In conclusion, my findings in this experiment state that the colour attracts the heat more. The colour white attracts less heat. We found out that solar panels are coloured black because black attracts more heat. In other hot countries, they don’t paint their houses black because they don’t want to be hot, so they paint their houses white.
