The experiment, which involves a comparison between the length of plant leaves in shaded and not-shaded areas, has to be done in a very structured way. First of all, I will get all materials: a tape measure or digital calliper for accurate measurement, a notebook or any other digital device to take down all the data measured (what I started with), and marker flags or stakes to mark out particular areas.
First, select two diverse locations in the garden: one beneath the trees, which is always in the shade, and another in a location that is always in full sunlight, that is to say, in an open area without trees. Both these locations should have the same kind of plants so that any comparison between the two will be relevant. Define these two areas as shaded and non-shaded with marker flags or stakes. To be consistent, I would try to make both areas the same in size; for example, I can take a 1m x 1m grid as a standard-size plot for both areas. Inside each area marked off, randomly choose certain points from where I will make a measurement of the leaf length. This randomization is important to avoid bias and to get a sample that is representative of the area as a whole. I will select 5 random points in each area.
Hypothesis: As the leaves get less shadow or high sunlight the leaves will be larger because soil moisture and light levels would be low.
Prediction: I am expecting to see the larger leaves in the areas that has low soil moisture level because of the shadow. Where the once that are under the sunlight all the time have larger leaves.
Response Variable: The leaves size.
Predictor: Soil moisture level at different times
