Your cell phone should be away during class today unless you are accessing the website.
Journal Entry:
What do you have to measure for this lab? What will you be calculating later?
Learning Intentions
We will learn how to calculate surface area and volume for different shapes.
We will learn how to determine diffusion rate for a cell.
We will learn how to describe agar with phenolphthalein and NaOH and explain how they will change when HCl is added.
Closing Task:
You can effectively collect your data for Part 2 of Osmosis and Diffusion lab
You can determine which has the greatest affect on diffusion rate, surface area, volume or surface area to volume ratio.
