Scientific method essay

The experiment isn’t adequate because there are multiple factors when there can only be one independent variable. 2. If Tyrone and Valerie both fly differently designed paper airplanes then Throne’s will fly farther because it has longer wings in comparison to Valerie?s wings. Independent variable: length of wings b. Dependent variables: type of paper, wind (if any), shape of plane, width of the actual plane, 3. Gather materials height the planes where thrown at -using the same type of paper fold accurately so the wings are different sizes however same shape fly the planes inside at the same time so there aren’t any environmental factors – measure distance from the starting point to where the planes landed, repeat step 3 and 4 3 times conclusion part 2 -compare and analyze results…. Formulate a Purpose: Jenny and Cattail are twin sisters with very busy schedules. They want to see if it is faster to drive home straight from the spinning class at the gym and shower or shower at the gym then drive home.

Research: From LA fitness (neighborhood gym) to the girls’ houses, taking the main road, it is 8 minutes without traffic and all green lights. However the traffic is usually heavy from Mom and moderate from 6:10-7100. Spinning class runs from 4:45-5:45. Jenny and Cattail both take 15 minute showers. Hypothesis: If Cattail waits till she gets home to shower and goes straight there after spinning class then she will not be ready faster than Jenny who is showering at the gym and then heading home because she will have to sit in traffic.

Experiment: Cattail and Jenny will test this hypothesis by timing themselves from the time they leave the spinning class till the time when they have dinner which is directly after their spinning class, shower and drive home. They will repeat this experiment every school day for a week for a total of five trials. Cattail Will leave the gym approximately at 5:45 and drive straight home then shower for fifteen minutes meanwhile Jenny showers at LA for fifteen minutes then drives straight home. Identifying Variables: 1 . Independent variable: order of activities post spinning class 2. Dependent variable: time efficiency, the amount of time that it takes to complete both activities 3. Controlled: the same route home, same amount of time to shower, same time zone, and the girls must start timing themselves at the same time. Controlling Variables: Both girls must take the main road home to avoid shaving off minutes by taking short cuts or back roads. Both girls must take no longer than 15 minutes to shower to avoid creating another factor. Can also be timed with a watch or clock. ) From the time the spinning class ends till the time when the girls are both showered and home they will be timing themselves so they must not do any other activities. Analysis: The total time it took to complete the activities for each girl would be recorded and then compared to see which method was more time efficient. Conclusion: If Cattail sits in traffic while Jenny showers at the gym then Jenny will be ready before Cattail because Cattail still has to shower once she gets home.

If Cattail manages to get home regardless of traffic and showers while Jenny is about to head back then that method will be more effective. 1) Independent variable: order of activities post spinning class 2) Dependent variable: time efficiency, the amount of time that it takes to complete both activities 3) Controlled: the same route home, same amount of time to shower, same time zone, and the girls must start timing themselves at the same time.
