Water clock investigation

The water clock

We were learning to compare non-standard unit and standard unit of telling time in periods of 15 minutes. We investigated how much water dripped in 15 minutes and we measured them in 3 attempts.

Water clock experiment

Materials:

Beaker

Pin

Plastic cups

Bowl

Water

Bottle

Instructions:

• First you must find a beaker and a plastic cup.

• Get a pin and poke the bottom of the plastic cup.
• After poking a hole find a flat surface to put your experiment on top of the table.
• Get a camera to film and a timer to time your experiment.
• Set the timer to 15 minutes.
• Fill the cup with water.
• Put the cup with a hole on top of the beaker and start the timer and  the camera at the same time.
• As soon as the timer hits zero pull the cup up and put your finger to the hole of the cup and run to the nearest sink to  tip the remaining water out.
• Measure the water from the beaker and write down the first attempt in millilitres.
• Do the same experiment for second and third attempts.
• Write the results of all the trials.
• If  all attempts have the same measurements then you have done it right, if not them you have to take the average of all attempts or trials.
