What's osmosis got to do with Little House on the Prairie?


Well, more than you'd think. Today we read about "sugar snow" which was when you'd get a late frost after the maple sap had already started moving so you'd get more sap out of the maple trees. To demonstrate how the sap runs through trees and brings the water up, we first taped 3 straws together to show how it was much harder to suck water up through 3 straws as opposed to 1. Then we cut a potato in half and put it in some water with a shallow hole scooped out. We put food coloring in each half and sugar in one half so tomorrow morning we can observe which one has drawn more water up.

We also tasted log cabin syrup and compared it against real maple syrup. We talked about the ingredients of each and the price difference. It was decided that the real maple syrup was definitely worth it.
