Problem: (Class perspective) We want to see the effects on different manipulated variables. We are the controlled group.
Hypothesis: If there are no manipulated variables, then there will be no change in the leaf because there is no influence on it.
Describe how the control would be set up: The leaf would be connected to the potometer and there would be no other outside effects on the plant.
Description of 3 Constant factors used in this lab:
Graph paper - one paper for each leaf
Time- One minute intervals for fifteen minutes
Potometer- one regular potometerWater- ¼ cup
Fill potometer with water and attach leaf at the end of the tube
Let leaf sit and record results every 1 minute intervals for 15 minutes. (there will be 7 data sets)
- Put transpiration information in table.
Manipulated variable procedure: We are the controlled group so we will not be having any manipulated variable of procedure.
Control Procedure: Are control will be at room temperature with no manipulated variables.
