Part 2: Design an Experiment for a Resource Consumption Simulation

New experiments often build on others. You have used cereal and spoons to model the effect of a variable on resource consumption under three different conditions. Now you will design a simulation to model the effect of another factor in resource consumption. In order to do this, you will ask a question, generate a hypothesis, and design and conduct an experimental procedure to test your hypothesis.

A. Ask a Question

Did any questions come to mind as you performed your experiment? For example, what if I had more time to collect resources? Here are some other possible scenarios you could explore by altering the procedure of simulation in Part 1.

What would happen if . . .

I could use something other than spoons to collect the resources (e. g., tweezers, fingers, etc.)?

I need to collect another type of resource (e. g., paper clips, beans, or pieces of pasta or rice)?

I need resources that are harder to find or get to (e. g., under tables and chairs or in other rooms)?

I need to collect a certain amount of a resource in order to survive (e. g., 50 resources per minute)?

Create your own question about one of the four scenarios given. Be sure to specify what variable you will change (independent variable) and how you will measure its effect (dependent variable). For example, if I increase the amount of time I collect resources with two spoons, will I be able to collect resources more quickly?

Write your question here. (1 point)

B. Write a Hypothesis

A hypothesis is your prediction about the results with an explanation of why you think that will happen. For example, I will collect twice as many resources in 2 minutes by using two spoons because I will have twice as much time.

Write your hypothesis here. (2 points)

C. Design an Experiment

The simulation you completed for Part 1 used pieces of cereal to test how the placement of resources (independent variable) affects the number of pieces (dependent variable) that can be collected in 1 minute with two spoons (variables held constant). An experiment should be designed to produce results that can be compared with other results. You may compare your new data with data from the original experiment (e. g., Tests A, B, and C of Part 1) or with data from different tests designed into your experimental procedure, as you did in Part 1.

You can use a procedure with steps similar to those in Part 1, but you will need to alter the steps to fit the hypothesis you want to test. You will need to specify:

the independent variable you will test (e. g., collection device, type of resource, location of resources, amount of time)

the variables to hold constant (all variables except the independent variable)

how you will measure the dependent variable (e. g., count of numbers, ratio of resources to people, etc.) and develop a data table for recording your data.

Analyze Data and Draw Conclusions

1. Analyze the resource consumption in Part 1.
a. Go back to your data table in Part 1. Figure out the average rate of consumption for each test. Round the answer to the nearest tenth. (2 points)

Test A Average Rate =

Test B Average Rate =

Test C Average Rate =
b. Summarize the results in Part 1. How did the three tests compare with one another? Explain why you think the results occurred the way that they did. (2 points)
2. Analyze the resource consumption in Part 2.
a. Go back to your data table in Part 2. Figure out the average consumption rate in pieces per minute for resources collected in 1 minute and resources collected in 2 minutes. Round the answer to the nearest tenth. (2 points)

Average rate for pieces collected in 1 minute:

Average rate for pieces collected in 2 minutes:
b. Summarize the results in Part 2. How did your experimental results compare with the results in Part 1? Explain why you think the results occurred the way that they did. (2 points)
c. Was your hypothesis supported? How do you know? (1 point)
d. What does your experiment in part 2 attempt to model about resource consumption in real life? What did it teach you about resources in the real world? (1 point)
