Week 2: Project Proposal Finalization (In Class Meeting)

The group came into class and learned about the process of making hydrogels. He further explained the properties of hydrogels and how to manipulate them using different alginate concentrations and calcium chloride concentrations. Two members of the team, Dami and Vriti, helped with the demonstration where they created the hydrogels by dropping the alginate into varied concentrations of calcium chloride solution using a pipet. The remaining time in the class was spent ordering the different supplies we need for the project. The materials acquired are listed below.
