The aim of this investigating is to see whether I can discover a definite relationship between the weak volume onto the leafs bulge appear and the surface scope of the leaf.
Hypothesis
I think the light eagerness could affect the surface bea in the following musical mode:
·A higher light intensity could make the surface area of the leaf large.
The reason I think a higher light intensity could make the surface area larger is the fact that in that location would be a larger amount of chlorophyll, containing chloroplasts, for photosynthesis. By having leaves of a larger surface area, there would be a much more efficient procedure of the chloroplasts (containing chlorophyll) and the high intensity light available.
Apparatus
In cast to carry out this experiment we forget need:
·A light analyze
·A graphing calculating machine
·A ruler
Method
·Connect the light probe to the graphing calculator
·Program the graphing calculator to deal with light probes
·Place the light probe in the middle of four leaves.
·Make sure the light probe is pointing in the same direction as the leaves and is facing remote from the leaves
·Take the light intensity reading and put it in a table of results
·Measure the length and width of each of the four surrounding leaves and record these results
·Repeat the test 15 times, trying to get a wide range of light intensities.
To make this test a fair test, I will have to control several variables. These are the temperature, the age of the leaves and the eatable of the leaves.
To control the temperature I will be carrying out the investigation on the same day, in as short a period of time as possible.
By using the same fake throughout the investigation, I should be able to ensure that the leaves are getting the same...
