We completed our first practical to explore the relationship between diffusion and cell size by experimenting with model “cells.”
Those are the instructions on how to prepare the agar solution. As a first experiment, I do not give any written instructions to my students. We have a 10 minute briefing and then they have to come up with their own experiment. They are not used to that kind of freedom in a lab and it gives them a taste of what the experiments in biology will be like.
They have their first attempt at completing a full lab report.
