Experemental Design
A. What is the Scientific Method?The Scientific Method is a procedure that was made science easier since the 17th century .There are a'lot of things involved such as Measurement , Experiments , testing things out , Hypothesis & so on.

D. Practicing the Scientific Method
I explored 1) graphing, 2) identifying variables, 3) developing hypotheses, 4-5) designing a controlled experiment and 6) predicting results with a partner.
E. Experimental DataPart 1: I was given data to make a graph, below. I used a Google spreadsheet to create a graph and I saved my image file to upload here. My graph demonstrates an inverse relationship between concentration of ethylene and time for maturation days because it was observed that as concentration of ethylene increases, time for maturation days decreases. This is be due to the effects of ethylene.... which is known to be released by plants naturally which causes plants to grow

F. Variables
G. HypothesisPart 3: I selected sun from a list of environmental variables I developed with a partner.
I believe that the amount of sunlight may affect the growth of a variety of apple trees because I have observed tree growth and seen faster growth rates in trees that receive more sunlight If my hypothesis is true, I will see tree growth as measured by growth in feet . Independent Variable: sunlight Dependent Variable: Tree growth H. Control GroupsControl group : The trees that have not been watered a lot.
Experimental group: The trees that get more water than needed. |

J. Expected ResultsPart 6: I would expect to see trees grow faster because of the amount of sunlight it receives. If my hypothesis that sunlight will affect tree growth is true, I will see faster tree growth as measured by feet.
