Question

• Will black pastic heat a solar water heaterfaster than white?
• If Icover a solar water heater with a lid will it heat faster than without one?
  

Hypothesis

If the lid covers the black tub,

Then the water will heat quicker.

Conclusion

Covered black heats the most because it increases by 4 degrees, and that was the most.

 If I could change something then I'd change the liquid.  My question would be which liquid would heat the most?
