Example #1- Research Inquiry

Claim: The use of hormones in agriculture does not affect human health.

Research Question: Does hormone recombinant bovine somatotropin (rBST) affect human growth hormone receptors through the consumption of cow’s milk?

Developing the research question:

Steps

Details

1. Identify the key (important) terms in the claim.

 

a. hormone

b. agriculture

c. human health

 

2. Propose questions that need to be addressed to refine key terms and narrow the focus of the claim.

 

a. Which hormone?

b. Which agricultural industry?

c. Where is the agricultural industry located?

d. What effect could the addition of this hormone have on an aspect of human health?

 

3. Conduct research to gather information to address the questions

a. Do hormones affect human health?

b. Are there hormones from animals in food consumed by humans?

c. Which hormone is found in cow’s milk?

 

4. Draft the research question to address the claim.

 

a. Does recombinant bovine somatotropin affect human health?

 

5. Refine and focus the research question.

 

a. Does recombinant bovine somatotropin (rBST) affect human health through the consumption of cow’s milk?

6. Present the research question to the teacher for approval.

a. Does hormone recombinant bovine somatotropin (rBST) affect human growth hormone receptors through the consumption of cow’s milk?

Example #2- Research Inquiry

Claim: Sustainable reserve size should be based on the data from gene pool variability.

Research question template: Does x of y increase the z of c to (maintain 90% heterozygosity)?

Research question: Does supplementing the prey population of the cheetah (Acinonyx jubatus) increase the carrying capacity in the [named] reserve to maintain 90% heterozygosity?

Developing the research question:

Steps

Details

1. Identify the key (important) terms in the claim.

a. ‘gene pool’

b. ‘variability’

c. ‘sustainable reserve size’

 

2. Propose refining questions that need to be addressed to refine key terms and narrow the focus of the claim.

a. The gene pool for which animal?

b. Where is the reserve?

c. What size reserve is needed to maintain variability?

d. How would we know the variability was sustainable?

 

3. Provide an example of how one of the claims could be developed into a research question.

 

Conduct research to gather information to address the refining questions.

 

a. The [named] cheetah reserve maintains genetic diversity.

b. The [named] cheetah reserve maintains 90% genetic diversity by supplementing the prey population.

c. Does supplementing the prey population of the cheetah in the [named] reserve maintain 90% genetic diversity?

 

4. Draft the research question to address the claim.

a. Does supplementing the prey population of the cheetah in the [named] reserve maintain 90% genetic diversity?

 

5. Refine and focus the research question.

a. Does supplementing the prey population of the cheetah (Acinonyx jubatus) in the [named] reserve maintain 90% heterozygosity?

6. Present the research question to the teacher for approval.

a. Does supplementing the prey population of the cheetah (Acinonyx jubatus) increase the carrying capacity in the [named] reserve to maintain 90% heterozygosity?
