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

Hypothesis:

I think the black cup will get the hottest because I know wearing black clouths in the sun you get hotter than normal, also because black attracts the sun the most. 

Materials:

1.  2x  Styrofoam cups 
2.  Tin foil 
3. Black plastic bag
4. Heat lamps 
5. White paper 
6. plastic cup
7. thermometer

Steps

1.  Get the materials 
2.  Put the tin foil inside a cup and also put black paper around another cup. 
3.  Put water inside all of the 3 cups.
4.  Shine the  light onto all 3 of the cups.
5.   Wait for 15 minutes then put a thermometer inside all 3  cups and see the tempter.
6. Record the temperature.
7.  Wait another 30 minutes then see the results after that.
8. Record the temperature. 
9.  Then wait 45 minutes and then see  the results after that.
10. Record the temperature.

Findings:

In this Photo we have 2 Styrofoams cups and one plastic cup, we have put water in each cups and used a heat lamp to shine onto all 3 off the cups and then we have waited 15 mins and then put the thermometer into each cup and see the results. 

Time	Cup 1 White	Cup 2 Black	Cup 3 Tinfoil
0	16	16	16
15	18	19	19
30	19	24	20
45		23

Conclusion

After getting everything set up and into place, and waited up to around 45 minutes to see all the results we have came to black  is the hottest one. Which this proves that  black get's the hottest when the sun is shining onto something that is black .
