Osmosis Lab Parts A→C & CER (part D)

 

Part D CER
This part of the lab is a group evaluation.

 

You and your lab team will create an argument about the molar concentration of the unknown solution and the water potential of the carrot cells. An argument is typically set up with the claim (in this case your suspected unknown molar concentration), evidence gathered throughout the lab experience, and reasoning (using what you’ve learned about tonicity and osmoregulation to support your claim.

 

Guiding Question:  What question were you trying to answer in the experiment?

Our Claim: What is your conclusion? You claim should address:

Unknown Solutions A→F (part A)

Water potential of the carrots (part C)

Mystery (?) solution with the carrots

 

Our Evidence: What data or information did you gather to lead you to the claim? Use your packet tables and calculations!

 

Our Justification  Reasoning: What ideas or principles from class support your claim? Does the evidence seem reasonable with what you know? Use class notes, slides, textbook, etc.

 

The score for the CER will be a group evaluation.  The presentation will be scored using the following rubric.
