Alfie has two plants, A and B. He used some Vaseline to coat the top of the leaves on plant A and the underside of the leaves on plant B. He left the plants on the windowsill for a week and watered them regularly.
a) What do you expect happened to each plant? Plant A: __________________________________ Plant B: __________________________________
b) Explain the result you have predicted for plant B
I think plant A would use a moderate amount of water and would use the least amount of water. I think plant B would use the least amounts because coating the lower surface causes the water loss similar to coating both surfaces (upper and lower).
What are your thoughts on this?
