How To Do A Water Clock Experiment

How to do Water Clock

  • Beaker
  • Plastic cup
  • A sharp object
  • Water
  • Bowl
  • Group (Optional)
  • Water bottle (Optional)
  • Paper Towels (Just in case of a mess)
  • A book

  • The first thing you have to do is create a little hole in the plastic cup. To do this, you use a sharp object. My group and I used a safety pin.
  • Then, add water to the cup. You can use a water bottle to pour the water for minimum mess.
  • In this experiment, my group timed the water clock for 15 mins and waited. Though, you can choose a different time.
  • After it is 15 mins, you measure how high the water dripped into the beaker. Then, write down the results into a book so that you can record your experiment and calculate the average once the experiment is finished.
  • Pour the water into a bowl. Refill the plastic cup again with water.
  • Wait 15 minutes again. Then, measure the amount of water in the beaker and record it down in the book.
  • Do this experiment 3x. When the experiment is finally completed, find the average of the totals. Once, the average is found, see if your results are accurate or inaccurate.

1st Attempt

The water was dripping faster than we expected it to drip. After 8 minutes, the water surprisingly stopped dripping so we loosened the cup from the beaker. Then the water suddenly dropped fast again. Our results were about the same as the first, 110 mls.

2nd Attempt

The second attempt was different from the first. Sometimes, the water didn't move so Tino moved the cup to let the water come down again. The results were 110 mls

3rd Attempt

Our third attempt was similar to our second attempt. The water stopped from time to time and we kept loosening the cup. Though, the results were very different. 80 mls was our results.
