Science Lab Report
Introduction
Objective: How do the different routes to the gym affect the energy saved?
Hypothesis: The shortest route from Mr. Jared’s class to the gym will save the most energy.
Variables:
Independent: The 3 routes, Horizontal and Vertical factors
Dependent: The distance, Amount of energy saved, Time taken
Control: The pace of steps taken
Problem to Solve
The major problem to solve in this test would be measuring the amount of energy saved by both horizontal and vertical paths.
Analysis and Evaluation
Walking on horizontal paths, or paths that are flat, will require less energy than walking vertically upward on stairs or on an incline, as less energy is expended walking on a flat surface. Obviously, the higher the percentage of inclination, the more energy is required to execute each step. Gravity also affects the amount of energy burnt when walking vertically as we burn more energy forcing our body weight upward when gravity pushes us downward.
Judgment
The Horizontal and Vertical factors will affect the final results of the trials as the amount of energy expended will differ for each task according to the percent of inclination. Walking horizontally on a flat surface requires less energy as opposed to walking vertically which requires us to exert more energy.
Method
Materials
Hand Tally Counter
Route 1: Walk down from Mr. Jared’s class toward the stair on the left, turn right and walk down the steps to the Blue Court, walk down toward the swimming pool and into the gym. Record the data with the tally counter on the way there.
Route 2: Turn right from Mr. Jared’s class and walk down the stairs that lead to the last floor, turn right and walk down the stairs to the gym. Record the data with the tally counter on the way there.
Route 3: Turn right from Mr. Jared’s class and walk down the stairs stop on the canteen floor and walk right from the canteen to the stairs that lead to the blue court. Walk down until you reach the gym. Record the data with the tally counter on the way there.
Method
Walk by following the instructions for Route 1 (record the data with the tally counter on the way)
Walk by following the instructions for Route 2 (record the data with the tally counter on the way)
Walk by following the instructions for Route 3 (record the data with the tally counter on the way)
Data Organization and Presentation
Data Explanation
The graph and table above show how the amount of steps taken vary from one route to the next. As shown in the data above, it took an average of about 500 steps to reach route 1. The graph further explains how many steps it took for the last 2 routes, about 400 steps each. Overall, route 2 saved more energy than the other routes as it took less time to complete than the other 2 routes.
Data Evaluation
The data is quite reliable because we have executed 3 trials with results that are close with each other. Even though the trials might have helped made it reliable, several factors may have affected the final result. Some of these factors include: walking in different paces, taking larger steps, and starting the tally counter too early. The results were within very close range of each other than indicates that our data in each trial is quite reliable.
Conclusion
The different routes to the gym effect the energy saved. This statement is true, as the amount of steps taken will effect how much energy is burnt. The more steps taken the more energy will be burnt. Stairs also affected the energy saved. As shown in the results, the more stairs there are in a route the more energy is burnt because more pressure and force exerted on each step than walking horizontally on a flat surface. For example, Route to proved to be the best energy saving route as it had less vertical steps – meaning less pressure was exerted on the route, which must have helped saved the energy.
Method Evaluation
The method we created was very helpful and helped us throughout all three trials. The method was easy to follow even though we made a few minor errors. The method didn’t tell us how many cm there had to be from one step to the next, which might have made our results a bit less reliable. We can improve by including additional information on the number of cm apart from each step and on how to use the hand tally counter.
Extension
Next experiment, I suggest we include more than two people who participate in each trial, thus making the results a bit more reliable. We could also use a pedometer that would count the number of steps and giving further information on the calories burnt, further supporting our answer to the objective. Another extension that would help with the data’s reliability would be testing if running would affect the energy saved and measuring how many calories burnt in doing so.
My partner and I did well in collecting data of the assignment. I collect reliable data of the exeperiment, collecting steps and calories of 3 different routes. We can improve it by using accurate gadget to measure and to count the steps and
