Hurumanu-Solar Energy


Aim: To find out which colour attracts the suns heat.
                                                                                                                               Here is some stuff that powered?
  1. robots 
  2. light
  3. small toys 
  4. NASA rover.
  5. R.C cars
  6. lime scooters
  7. cars
  8. satellites

Hypothesis:

I think that the white will attract the most heat because on soler panels the edges are white.

Materials:

  1. white cups
  2.   tin foil
  3.  black  plastic
  4.   heat lamp
  5. white paper
  6. thermometer 
  7. water
  8. clear cup
  9. silver cup

Step

  1.  Put the three types of cups on a table evenly spread. 
  2.   Put some water in each cup
  3. Plug the heat lamp and place it down on the table.
  4. After 15 min cheek the temperature of each cup by putting the thermometer in the water.
  5. Record the info until it hits 45 minutes.
  6. Record your findings.

Findings:


The black cup heated faster than the other ones. The white only heated up 2 degrees in 45 minutes. That is the same as the silver cup as the white one.

At the fifteen min mark, it was still the same they only went one up.  
in the back round, there is the heat lamp. On the right is the white cup. In the middle, there is a black one. And last of all is the silver one. Here is a video

Conclusion

In conclusion, I found that the black cup heated faster than all the others. It heated to 22 degrees. Now, why is black heated faster than all the other colours? Soler pannals are black so that because it attracts the sun.  In hot countries, they paint there houses white because if it was balck it would be hot. 

The white cup was tied with the tin foil at 18 degrees. I have learnt the darker colours heat faster. I also learnt that heat lamps can get very hot in short amounts of time. The colour black gets heated faster. This is why solar panels are a dark colour or black
