God's Green Leafations
by: Michelle G., Katie D., Aimee M., Jaci V.
If the group took a leaf and a potometer to measure the intake of the water, and we changed the temperature of the water, then the amount of the water taken in by the leaf is liable to increase.
1. The potometer which is two clamps with one pipe that will hold the water
2. The leaf which is our organically grown specimen for our experiment
3. The water which is our slightly altered manipulated variable.
7. Data table
Put a leaf into the tube held up by two clamps.
Warm up water
Load water into syringe
on the other end of the tube start putting the water into the tube
- at our given increments look and see if the leaf soaks up the mixture more each time period.
Orange is the increase in temperature
Red is increased heat
We believe that our leaf didn’t absorb as much water due to the fact that we put the vaseline directly onto the leaf instead of placing it on the top to seal out air. By changing the temperature of the water, we hypothesized that the leaf would soak up more water at a quicker pace. By looking at the data the rates of absorption by each group seemed to be about the same gradual change.
