Math DLO

This is the work that I have done the past 2 weeks for math. I enjoyed this for the most part but some I found tedious and not very fun.

Solar energy

Solar Energy

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

Hypothesis: Black

Materials: 

1.  2 x styrofoam cups 
2.  tin foil 
3. Plastic cup
4. heat lamp 
5.  white paper 
6. 
   

Steps

1. 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 tempter 
   7.  Wait another 30 minutes then see the results after that.
   8. Record the tempter 
   9.  Then wait 45 minutes and then see  the results after that.
   10. Record the temperature for the final results.

 Findings:

This is a photo of cups and a light and different shades to see which one gets hotter.

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

Conclusion

The black cup was the hottest as I had predicted but the other cups were alot colder than I expected.
