PRESENTATION OUTLINE
How do increasing global temperatures affect the rate of transpiration?
Hypothesis: If global temperatures steadily increase then palm trees will transpire at a longer and higher than fir and oak trees.
Experimental Design:
To test our hypothesis, we can use leaves from palm, oak and fir trees and place them individually onto potometers with different amount of heat being directed towards it using different light bulbs while calculating the rate of transpiration which we will then compare to see which has the highest rate of transpiration in the hottest temperature.
Expected results:
We think that the palm tree will have the highest rate of transpiration in the hottest temperature because palm trees are very well adapted to hot temperatures compared to the others.
Why we care? :
With new industrial revolutions more pollution has been released into the atmosphere by humans increasing the global temperature, with this increase plants can be affected enough to the point where they don't transpire as the climate is too hot for them to withstand. If this continues, plants would not be able to provide oxygen for humans, harming the human race.
