Experimental Design
A. What is Scientific MethodScientific Method is procedures for an experiment consisting observation, asking a question, Hypothesis, Experiment, Analyze, Conclusion. To get the results.

C. Scientific Method Steps1. Observation - observing the experiment to gain information
2. Ask a Question - ask a question that can be answered by being tested. 3. Hypothesis - Predict the outcome to the problem 4. Experiment - Develop a procedure to test the hypothesis 5. Analyze record the results of the experiment 6. Conclusion - Compare the hypothesis to the experiments conclusion. |
D. Practicing the Scientific Method
I explored 1) Graphing, 2) Identifying Variables, 3) Developing Hypothesis, 4-5) Designing a Controlled 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 of maturation because it was observed that as concentration of ethylene increases, time of maturation decreases. This is be due to the effects of ethylene which is known to be released by plants naturally which causes plants to grow faster in less amopunt of days.

F. VariblesPart 2: Potential environmental variables to consider:
G. HypothesisPart 3: I selected weather from a list of environmental variables I developed with a partner.
I believe that climate may affect the growth of a variety of apple trees because if you keep your apple tree in a green house it would grow faster rather than having them outside somewhere the weather can affect their growth. If my hypothesis is true, I will see different varieties of apple tree growths as measured by observation . Dependent Variable: Is the apple growth and colors of apples. Independent Variable: The weather |
J. Expected Results
I would expect to see concentr because... If my hypothesis that x will affect y is true, I will see... as measured by...

H. Control GroupsPart 4: It is important to control variables in an experiment because if you don't control something you cant compare your data to anything. your control is what you base you experiment on.
Control Group:a group of apples Inside of the greenhouse Experimental Group/s: A group of apples outside dealing with the different weather climates. |
Part 6: We believe that the weather may affect the growth of variety of apple trees because if you keep you apple tree in a green house it would grow faster rather than having them outside somewhere the weather can affect their growth. If my hypothesis is true i will see different varieties of apple growth.
