Water Clock

Water clock

Problem: How much water drips in 15 minutes?

Materials you will need: Beaker, Plastic Cup, Bowl and Electronic.

What did Joshua C, Maranita and I do?

We did 3 attempts to get the correct answer for our water clock experiment but sadly our experiment was inaccurate.

Observation

We saw other group's experiments and compared ours to theirs and I figured out our water drops from the water clock, were going faster than the other groups.

We filmed it and recorded videos but I also noticed that our hole was small and the water drops were going fast because we didn't add pressure on the cup. It was so fast that our results were very different.

Instructions on how to make your own water clock

Firstly  you grab the materials needed which are a beaker,plastic cup,safety pin, bowl and a eletronic to time and record your three attempts.

Second step it to get the safety pin from your materials and poke a small hole in the plastic cup so the water can flow through the plastic cup into the beaker for the right attempt.

After you have poked a small hole into the plastic cup, you get the plastic cup and put it in the beaker. Then you pour water into the plastic cup and wait for the water to drop rapidly while you film and record the time on your electronic.

When 15 minutes is up you get the bowl and take out the plastic cup full of water, and tip it in the bowl.

Finally you measure the water in order to get your results for your water clock.

If it is incorrect you can do a second attempt so you can get a right result.
