Case Study Lobster Protein Synthesis

Open Ended

The Norm

1-  If the lobsters tend to be the same color, this green/blueish with red mix, can you predict the genetics for coloring in a lobster?  Is there one or more genes responsible for coloring?

Why Do Crabs and Lobsters Turn Red When You Cook Them?

2 -   If they start off the dark color, can you make a prediction why the coloring changes to the bright red when cooked?

3 - Explain what is occurring in Advanced Biology terms

BUT… have you ever seen a blue lobster?

4 -Make a prediction of how you get a blue lobster?

Open Ended

5 -What color do you think it will be when cooked?  Why?

Open Ended

6 -Why do you think they would still turn red?  From what you read previously in this case study come up with an explanation?

7 - Why do you think these lobsters are orange or red naturally and not the standard red/blueish/green that we tend to see?

8 - So what color do you think these will appear when boiled?

9 - Whether calico or yellow, what color would you predict when boiled?

Open Ended

Still RED!!!!

10 - What would be your advanced biology knowledge to explain that!!!

Open Ended

What???

11 - Try to explain this phenomenon?  I believe I told you a story that might help in your explanation!!

Open Ended

12 - How do you think that these occur?

13 - Does this image alter your explanation from the previous slide?

14 - What color do you think this will be when boiled?

15 - So here is the last question,  the prediction is that more and more often we will be seeing these in nature?  Why might they not be seen often in nature?  What might be a reason the scientist will believe we are going to see them more often?
