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

Hypothesis: 

I think that the silver is going to heat better because it is tin foil it is metal.

Materials:

1.  x3 cups (x1 plastic cup x2 styrophome cup)
2.  x1 tin foil paper
3.  x1 paper
4.  x1 black plastic
5.  x1 thermometer
6. x1 heat lamp

Steps

1.  Get your 3 cups 
2.  Put the tin foil cup on the tin foil
3.  Put the plastic cup on the plastic
4.  Put the white cup on the white paper
5.  Pour the water in the cups 1/4 way
6. Turn the heat lamp on and put it in front of all the cups
7. Put a timer on for 15 minutes and wait
8. When that 15 minutes is up put the thermometer in the cup for 1 minute then  take it out for 1 minute and see what it is
9. Do all the other cups
10. Record your findings
11. Lastly do your conclusion

Findings:

Time	Cup 1 White	Cup 2 Black	Cup 3 Tinfoil
0	16	16	16
15	18	19	19
30	19	24	30
45	20	29	35

Conclusion

In this picture there is three cups with different things on it one has nothing on it and the other two have tin foil or a plastic bag and they are on the top of the colour of the cup.
