Given a variety of jumpers with different mass “hats,” determine the mass of a hat-less jumper.
Describe an experimental procedure the student could use to collect the data needed to find the mass of a 'hat-less popper'.
Describe how the data from the measurements could be analyzed to determine the mass of the 'hat-less popper'.
Does the experiment described in parts (1) and (2) depend on the assumption that the energy stored is independent of the poppers mass?
Briefly describe how the experimental procedure described in parts (1) and (2) could be modified to determine whether the stored energy stays constant as the mass of the popper changes. If no modification is necessary, state that explicitly. In either case, describe how the data could be analyzed to determine whether the stored energy stays constant as the mass changes.
Question #1:
(2 marks) Materials and Usage:
Using the Quantity to be Measured / Equipment for Measurement materials list to include any and all materials used in your procedure. Underline the materials in your procedure.
1 mark is earned: For indicating valid measured quantities
1 mark is earned: For a list of equipment and a plausible way to measure the quantities stated
Indicate the quantities to be measured and the equipment you are going to use to collect these measurements.
Draw a clearly labeled diagram, include where the measurements/variables are located on your diagram.
Describe how you would use the equipment to conduct the experiment.
A minimal number of steps in bulleted format.
Be sure to include how you will use each piece of equipment and how you will measure each of the variables defined in your table.
Define the terms you use in your experiment
Sketch a predicted graph of your data. Include the appropriate labels on your axis.
(3 Marks) Procedure:
Create a procedure that will answer the proposed issue.
Strong Suggestion: Write your procedure in the OAIM format.
Object:
Action:
Instrument / Equipment:
Measurement:
Include HAND DRAWN diagrams of any unique setups. Drawing talent is not graded, however, ambiguous parts should be clearly labeled.
1 mark is earned: For a practical procedure consistent with the quantities indicated in (a)(i)
1 mark is earned: For a plausible procedure that could be used to experimentally determine the relationship between mass and height.
1 mark is earned: For including a valid method to reduce experimental uncertainty - Say something about taking multiple measurements.
Question #2:
(3 Marks) Data/Observations
Create a meaningful and understandable method for displaying your data and observations. Use a table for any numeric data and be sure to include units and correct significant figures.
Any tables should include the following:
Trial numbers (Please don’t forget this. You may be asked to reference it.)
Measured and calculated data to appropriate decimal places.
Include the symbol and units in the title for each column
This is where you will house all calculations needed. Calculations should include a sample problem worked out, from formula to completion. If no calculations are required, explain the significance of the data:
What patterns/trends are noticed?
Is there a cause and effect? If so, what it is?
Any graphs should include the following:
Create a title for your graph
Label your axis with the measurement titles and the units
Create appropriate scales (remember, your data should use 80% of your graph space).
Identify the independent variable. (You can label this on the graph)
Identify the dependent variable. (You can label this on the graph)
What TYPE of graph is this? (Linear, inverse, square, …) Sketch the trendline. DO NOT “CONNECT THE DOTS”!!!
What is the meaning of the slope? Is it a physics law? If so, what is it?
What is the meaning of the area under the curve? Is it a physics law? If so, what is it?
1 point is earned: For a valid expression involving the necessary measured quantities consistent with the procedure.
1 point is earned: For explicitly or implicitly relating the calculated quantity to the mass of the 'hat-less popper'
1 point is earned: For correctly combining the above two concepts in a way that would yield the energy stored in the 'hat-less popper'
Question #3:
(2 Marks) Analysis
1 mark is earned: For correctly relating the procedure in parts (a) and (b) to the assumption of dependence or independence of height on the mass of the popper.
1 mark is earned: For connecting the analysis to the dependence of height to the mass of the popper.
(2 marks) Conclusion Question #4
This is the section where you will answer the original question or stated problem. All answers must be in the Claim-Evidence-Reasoning format.
1 point is earned: For a modification that has any additional trial at a OR correctly and explicitly stating that no modification is necessary
1 point is earned: For indicating how analysis of the initial or modified experiment could plausibly determine whether stored energy is independent of mass of popper.
