     My hypothesis was, if your solar water heater is covered and is black, then the water will heat up faster.

SCIENTIFIC PROCEDURES   

     1. Put water in your solar energy heater.

     2. Cut a hole in the lid (if you have a lid).

     3. Stick the thermometer in the hole you cut in the lid of your solar cooker. 

     4. Record the temperature.

     5. Go outside, put solar cooker in the sun, and wait five minutes, then record temperature.

     6. Wait five more minutes and record temperature again. Repeat once more. 

     7.  Come inside and discuss your results. 

     8. See which solar cooker of a)black uncovered, b) black covered, c) white uncovered, or d) white covered heated the water to           the highest temperature.                                                                                                                                              

RESULTS

     Black covered worked the best.  It worked the best because it soaked in the most solar energy.  Also black covered had a lid which helped keep in more thermal energy.  White uncovered worked the least best beacause it didn't soak up as much thermal energy and it let out thermal energy through the top because it didn't have a lid.

CONCLUSION

      My hypothosis was that the black covered solar water heater was the best at heating the water.  I was right because it turned out that the black covered was the best at heating the water in the end in my experiment.

CHANGES/NEW QUESTIONS

      I wouldn't take so long to make the parts for my experiment and I would have my new question be does a plastic cup with cardbourd on the top of it get hotter than a cup without a peice of cardbourd on it?
