Scientist of the Week #7

Heather did a great job being our scientist this week. She did a fun experiment that really surprised the kids. Here she is all set up and ready to go.

She did several experiments with water tension. First she did the pepper. The class predicted what would happen to the pepper. Most said it would fall to the bottom or float. We found out that the pepper floated on the water.

But when a drop of soap was added, the pepper spread out to the sides, very quickly!

Then she did it with toothpicks. We didn't know if it would work, because toothpicks are so much bigger. But it did! They quickly moved to the edge of the bowl when a drop of soap was added.

The last one Heather tried was baby powder. That worked even faster. It was so exciting!

What a fun experiment! Thank you, Heather. You did a great job!
