PROBLEM:

How does the type of light affect water’s evaporation rate?

HYPOTHESIS:

I think that  (place your own hypothesis here).

MATERIALS USED:

(Your materials might be a little different.  Use what you have.)

  • Eleven 9 ounce Solo cups
  • Water
  • Weight Scale
  • One Sharpie marker

EXPERIMENT:

  1. Fill five cups with an equal amount of water, labeling the cups A-E.
  2. Place cups in different places around the house.
  3. Wait four days and then mark the water level.
  4. Repeat steps 1-3 using five different cups labeled A2-E2.  Put cups in the exact same places as the first five cups.   Place A2 cup where A had been, etc.
  5. After four more days, weigh each of the ten cups with the water in them, including a control cup with the original amount of water.
  6. Average the two trials for each cup (A & A2, etc.) and calculate the percentages to see how much water evaporated.

RESULTS:

(Fill in the blanks with the percentages you got from your calculations.)

  1. Cup A:  ____% evaporated
  2. Cup B:  ____% evaporated
  3. Cup C:  ____% evaporated
  4. Cup D:  ____% evaporated
  5. Cup E:  ____% evaporated

CONCLUSION:

My hypothesis was supported by my experiment:  (Place your own conclusion here.)
