Cell Size and Diffusion Argumentation Lab
What I will do:
To share your work with others, we will be using a round-robin format.
We will rotate every five minutes.
Wear goggles when dealing with the weak acid solution
You will want to take notes as you go to keep your thoughts straight, as many of the experiments are likely to be similar.
Listeners will swap out with the presenter, and again after another two rotations, giving each group member an opportunity to defend your group’s work
Wash your hands when done.
Steps during the lab
Wear your goggles
the cubes
all the cubes into a breaker
Then pour the weak acid onto the cube inside the breaker
Leave it inside for 12 mins
Use a stopwatch to set the timer
While waiting for the cube to dissolve create a data table
After the cube had fully dissolved, use paper towels and dry cube completely off
Check to see if the cube has changed color to see whether the lab worked
Wear gloves to touch the dissolved indicator agar cube
Use the plastic knife to cut the dissolved indicator cube agar
Then use the ruler to measure
Record your data
State the explanation you are trying to support
Include genuine evidence (data, analysis, and interpretation)
Explain why the evidence is important and relevant
State the explanation you are trying to refute
Explain why the alternative explanation is invalid or unacceptable
Organize your argument in a way that aides readability.
Use a broad range of words including relevant vocabulary.
My claim: The rate of diffusion is related to cell size. Nutrients diffuse at a faster rate through small cells than they do through large cells.
Alternate Claim: Cells that have a larger surface area to volume ratio are more efficient at diffusing essential nutrients.
What you need: Indicator agar, Weak acid, beakers, stopwatch, ruler, and a plastic knife
