KSAT Kids Home Science: Pumpkin Density

Measure and find out which part of the pumpkin is the densest

Are you looking for something fun to do at home that has a little bit of science behind it?

SAN ANTONIO – Hello parents, teachers and students!

Are you looking for something fun to do at home that has a little bit of science behind it?

Well, check out this cool experiment that allows kids a fun way to learn about density. In the experiment (seen above) kids will take each part of the pumpkin (seeds, guts, flesh, and stem) out and submerge them to determine which parts have the most density and which have the least density.

The experiment is courtesy of steamsational.com.

Be sure to check out GMSA@9 on Wednesdays when Meteorologist Kaiti Blake does the demonstration and explains the significance behind it. To view the video, click on the player above.
