This lab will explore the water traffic across the plasma membrane. So, the science question is...
SCIENCE: Are Orbeez a good model for osmosis and the semi-permeable plasma membrane? What is the mystery solution?
QUESTIONS
Available Solutions and Polymers in Solutions
0%, 2%, 4%, 6%, 8% and a mystery solution

Biolab 7 Osmosis Notebook Experiment Orbeez.pdfPresenting your conclusion - CER 5- points
We are going to complete a presentation of your findings.
Claim: This is the conclusion or explanation that answers the guiding question.
Evidence: This either refutes or supports the claim. It is the data or findings from the research your
conducted. How does this information impact the claim?
Reason: This is a justification of the evidence. A statement that explains the importance of the evidence by making the concepts or assumptions underlying the analysis. Facts from class or the textbook would be great reasoning.
