C. Scientific Method StepsThe scientific method consists of 5 important steps. First, ask a question. This will determine what you will be looking for. Next, formulate a hypothesis. This is a prediction of what you believe the outcome will be. Third, perform the experiment. This is the actual testing of your experiment . Additionally, you then collect the data from your experiment. Lastly, you draw conclusions as to why your hypothesis was correct or incorrect.

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 Data1a) In this data/graph, the dependent variable is the amount of days it takes for the apples to mature.
1b) In this data graph, the independent variable is the concentration of Ethylene in ml/m^2 1c) Winesap- For the Winesap apples, the best amount that seems to produce the best results is 35 ml/m^2. Gala apples-35 ml/m2 Golden-35 ml/m2 |
F. VariablesPart 2: Potential evironment variables to consider:
G.HypothesisThe environmental variable that I chose was weather.
I believe that weather may affect the growth of a variety of apple trees because I have observed plants being put in warm weather and watered everyday, and seen that they grow at a faster pace than the ones who are not put in warm weather. If my hypothesis is true, I will see the plants in the sunlight grow faster than the ones in the cold and dark room as measured by the time it takes for apples to mature (viewing apple color). Independent Variable: The independent variable is weather. Dependent Variable: The dependent variable is the apple color. |

I. Control GroupsAn experiment should be controlled because it help keep the experiment organized and it helps view the effects of one variable.
Control Group: A group of apple trees in ideal weather (i.e. a greenhouse at 24 degrees Celsius). Experimental Groups:

J. Expected Results
If I would have recorded data, I would have recorded how they would change in color after every week. I would also have recorded if to much cold or warm weather affected the apple trees negatively and caused them to die.
Deeper Analysis
My question: What are the healing differences between an ACL, medial meniscal repair using hamstring v. patellar tendon repair
- Hypothesis: I believe that the anterior cruciate ligament reconstruction using the hamstring tendon will be more successful than using the patellar tendon because I have observed that using the hamstring tendon will cause less pain in kneeling and knee walking to the people.
- Independent : The independent variable in this experiment is the both surgical procedures that were performed without any implants by a press fit technique
Dependent: The dependent variable in this experiment is the ACL insufficient patients.
1) Gather sixty-two ACL-insufficient patients
2) Perform both surgical procedures without any implants by a press- fit technique
3) Drill the femoral tunnel through the anteromedial portal for anatomic placement
4) Then wait about 8.8 years after reconstruction
5) After the 8.8 years of reconstruction examine 53 patients by different clinical and functional tests
6) after, perform Bilateral MRI scans and interpret by an independent radiologist
7)See which surgical technique, was more effective and less painful during recovery
8) Record data and Results
4.Conclusions and Next questions: In conclusion, the implant-free press-fit technique for anterior cruciate ligament reconstruction by use of a bone-patellar tendon and hamstring grafts with anatomic graft placement was a much more better technique. It was concluded that there was less anterior pain in the hamstring group.
