Rising Water!

How is water affected by different objects?

Young Ones:

Use a bath tub crayon or some sort of marker and fill tub with water midway. Have each child enter tub and mark where the water line is after the slushing of the water calms down.  With bathing suits on have the adults participate to really see the difference of the water levels.

Fill a tub or bucket of water outside and have different objects for child to play with using the same skill of watching the water level. Discuss and ask lots of questions and have fun.

First Grade and Up:

You will Need:

Bucket, Glass jar with lid, Water

Fill bucket about three quarters full.

Place empty jar with lid on into the water. Do not push down yet. What happens?

Slowly push to bottom of bucket. Looking at sides of bucket and water line ask, does the water rise, fall or stay the same?

NOW, fill the jar with water and repeat.


Look into the ancient mathematician/philosopher Archimedes. He discovered the law that the volume of water displaced equals the volume of the object placed in the water.
