We’ve been working through the Montessori botany lessons. These lessons begin with the roots and move up the stems and into the leaves. We have been looking at how water pressure works. The soil to roots to stems to leaves to the atmosphere. We discussed capillary pressure; we discussed how the sun “sucks” the water further up into the leaves; we also discussed how water moves from the higher pressure to lower pressure.
Ms. Julie worked with a long length of garden hose, 1/4 in tubing – 8 feet in length, and 1/2 in tubing to demonstrate the principals of the xylem constructions.
After the demonstration, the kids began to play with the garden hose piece. Eventually they spent around thirty minutes trying to get it into the tree. Finally AV was employed to help.
