Preschool Science: Volume and Water Displacement

I get so tickled when my preschooler does things that I used to teach in 4th and 6th grade.
Understanding VOLUME is a huge concept in both grade levels.


This month with our preschool curriculum we are studying Fables and Folktales; one being 
The Crow and the Pitcher- an Aesop fable.

The story goes that there once was a crow who was so thirsty on a dry, hot, summer day and the only water that could be found was in a pitcher.  However try as he might, his beak could not reach the water.  Using his brain, he determined to drop pebbles in the pitcher causing the water to rise to where he could get drink.  Smart smart crow.

After reading the fable, we did the STEAM experiment that Mother Goose Time suggested in the teacher guide. 


We used a beaker from when we did the Science Lab unit from Mother Goose Time, and a bunch of plastic gems that MGT sent with this unit.  We drew a line with a dry erase marker at the water level and then watched it rise as my girl put more and more beads in the beaker.





"Momma, look!  It's getting higher and higher!"
As the water reached the top of the beaker, my girl tried to take a sip and she could fully understand how the crow was able to drink.  We emptied the beads and did the experiment again, 
and again, and again.
Because preschoolers...and science.  You have to do many tests to make sure the conclusion is valid. 

If I was teaching my 4th and 6th graders, this would be an excellent Engage lesson (5 E Lesson plan)
Using a beaker or graduated cylinder, kids could actually find the volume of a pebble or bead by subtracting the starting volume (water level) from the water level volume after the bead was placed inside. 

My little girl.... already doing big things in science.  Big concepts start early.
