WebQuest: Cuban Missile Crisis

The closest the world ever got to nuclear war was in 1962. President John F. Kennedy and Premier Nikita Khrushchev played a near disastrous game of brinksmanship as a Russian naval convoy believed to be carrying parts to create nuclear missile launching sites in Cuba sped towards a U.S. Naval blockade.

•  Reactant - substances that interact in a chemical reaction, listed on the left side of a chemical equation
•  Products - substances that are the result of a chemical reaction, listed on the right side of a chemical equation

Assignment:

For this assignment, you will be researching some enzymes and answering some discussion questions about how they work.

1. Research the enzyme pepsin. Where is this found? What is its purpose?

2. Research the enzyme helicase. Where is it used? Why is it important?

3. Research the enzyme lactase. What is its function? What reactions does it speed up? What is Lactose intolerance?

4. Research an enzyme used in digesting a certain food. What enzyme is it? What food is it used for? How does it help with digesting this food?

 

Submission:

You will submit the responses to the discussion questions as a list or in an essay format. This can be done on paper or uploaded in a document.

1. What was it the authors were trying to determine/establish with this study?

2. Did the authors have a hypothesis – if so, what was it. If they didn’t have one, should they? Explain why they should have had one and write a hypothesis. If you think they shouldn’t have had one, explain why

3. What are the key features of the experimental design?

4. Based on the overall design of the experiment and not on the outcome or results, does it seem reasonable (i.e. is what the authors are proposing to do seem fair, practical, based on good judgement) to carry out? Explain

5. Based on the overall design of the experiment and not on the outcome or results, does it seem feasible (i.e. is what the authors are proposing to do seem probable, likely, possible to do) to carry out? Explain.

6. What are the main findings from the experiment? (This does not mean list all the results from the experiment, instead think back to your answer to question 2)

7. Pick one of the results from the article (a table, chart, or figure). Explain what the result is showing and summarize the main points from the result, in your own words.

8. Do you think there was any bias in the experiment? When answering you must address both unintentional* and intentional** as part of your answer and explain how each would lead, or not lead, to bias.
*Unintentional bias such as being limited to the subjects that sign up for your study; **Intentional bias such as one of the researchers being a member of the pharmaceutical company that funded the research.
