During our leaf unit study for My Father's World Kindergarten I set up a simple science demonstration to teach J-Bug how a leaf gets water. We did this same demo back when JZ went through MFWK, and I have to say it is every bit as cool to me now as it was then. The best part is there is literally zero set up involved. Just grab a bag and find a tree!
Directions: J-Bug picked out a tree in our backyard, and I attached a Ziploc bag to it, enclosing a branch covered in leaves. I sealed the Ziploc enough to hold it in place. The first time we did this demonstration I used a plastic grocery bag and tied the handles in a knot to secure it. We left the bag on the tree for a week, checking it every day.
At the end of the week the bag had collected a good amount of water. I explained to J-Bug that plants absorb nutrients and water through their roots. The water flows through the veins of a tree like water in pipes reaching every leaf on every branch.
