Catching the sun movie

Materials:

1. 4 cups 
2. Water 
3. Tinfoil 
4. 2 sheets of white paper 
5. 1 sheet of black paper 
6. Thermometre 
7. 1 large cup
8. 1 heat lamp 

Steps

1.  Get your materials
2.  Fill your 4 cups with water so that quarter of it isn't filled 
3.  Put each cups on the papers/ tin foil 

• One cup on the foil 
• One cup on one of the white sheets 

• Another on the other white sheet and put the large cup on top of it making          the two cups connected 
• One the black paper.

4. Turn your heat lamp on and face it towards your cups  
5. Then wait for 40 minutes 
6. Once it’s over then use your   and check the temperature for each cup

Which surface conducts/attracts the most heat?

Time + temperature	Cup 1 White paper	Cup 2 White paper + plastic	Cup 3 Black paper	Cup 4 Tinfoil
0 minutes	12	12	12	12
40 minutes	17	21	23	29
minutes	20	15	24	20

 

Findings:

That somehow cup 1 heated up instead of cooling down

Cup 2 cooled down very fast 

Cup 3 only cooled down 1 degree

Cup 4 went 9 temperatures down which was a lot 

Conclusion

I think that this experiment went very well and it was quick and fun to do 

It also shows that all the water was from the same tap and was the same temperature at the start and then it heated at different temperatures
