Address the following for one of the Testable statements above; be sure you indicate WHICH statement you have chosen (7 pts):
If a plant is placed on a window sill, then it will grow faster than when it is placed on a coffee table in the middle of the living room.
• Write a hypothesis and null hypothesis
Hypothesis-a plant placed in a window sill will grow at a faster rate than a plant placed in the middle of a room
Null hypothesis-the location of a plant has no effect on its growth rate
• What are the dependent and independent variables?
The dependent variable is the growth rate of a plant. The independent variable is the location of the plant
• What is your control?
The control for this experiment is the plant which is placed in the middle of the room. The experimental plant is the one placed in the window sill
• How will you collect your data?
I will measure the growth of the plant each day using a tape measure. I will measure the height and width of both plants each day. I will also observe how many leaves are on each plant.
• How will you present your data (charts, graphs, types)?
I will use the data gathered to create a scatter graph that shows the amount of growth each day for each plant
• How will you analyze your data?
I will analyze the data both comparing the amount of growth for each plant. My prediction is that the plant in the window sill will receive more light and thus grow at a faster rate.
