Catching the sun movie

Materials:

1.  Cups (4)
2.  Water
3. Tin foil 
4.  2 sheets of white paper
5.  1 sheet black paper
6. thermometer
7. 1 large cup/

Steps

1.   Get a cups, four small cups and 1 large cup and black paper, white paper and foil.
2.  Put a water on the small cups but don't put too much.
3.  Get the large cup and put it on the top of the one small cup.
4.  After that place the 1 small cup on the white paper, 1 small cup on the white paper, one on the foil and the small cup with large cup on the top put it on the another white paper.
5.   Get a heat lamp and make sure that light from heat lamp is going to a cup with water.
6.  After that wait for 15 minutes before you measure the water and turn off the heat lamp and wait at least 15 minutes before open it again.

Which surface conducts / attracts the most heat?

Findings: 

I think our experiment going well because we find out the temperature and the temperature is going up and down.  But my group got confused because we have a lot of cup that we need to measure so we got confused. But i really enjoy this experiment because i learn how to measure the heat and i learn how the heat is forming.

Conclusion

I enjoy doing this experiment because i learn something new. We place our experiment kinda close to the door and while measuring the temperature of water we are sitting around our experiment which s helping to make more heat so that's why the heat is going up. I enjoy this because we did it right and we try and learn something new for science and because we did it right we an do our blog post right because we have the right details.
