Materials: Vegetable oil, water, syrup, a grape, a rock, an ice cube and a piece of cork. |
First, Alexis poured the water into the glass, followed by vegetable oil and then syrup. She documented what she saw.

She then dropped each of the items into the mixture.

Ice cube, grape, cork, rock |

The Results: The rock "hit rock bottom", as Alexis said. The grape floated on the syrup. The ice floated on the water. The cork floated on the oil. |
As well, the atoms in the cork were so loosely packed that they could not squeeze through the atoms in the water, oil or syrup. It just floated on top. The atoms in the ice cube were packed densely enough to pass through the atoms of the oil but not the atoms in the water. Thus, it floated on the water. The grape passed through the oil and the water but couldn't pass through the syrup. And finally, the rock "hit rock bottom" as Alexis said. It passed through all of the liquids.
And that was this week's experiment.
Have you done any cool experiments lately? What did your child learn? Did you make any discoveries of your own?
Happy Homeschooling!

Oh that experiment sounds fun! We are working our way thru the astronomy book right now. Ch 2. :)
ReplyDeleteShe thought it was fun. She proclaimed, "I LOVE science!!!" afterwards.
ReplyDeleteAh...so this is what her "I LOVE science" was about. :) And, the photo editing looks great! Good job to both of your kids!
ReplyDeleteThanks!
