The Portfolio Assignment
The portfolio assignment should include your data and graphs for the circuit elements and circuit arrangement portions of the electricity unit.
The first page of your portfolio should include an overview of what electricity is and should describe to the reader what you intend the rest of your portfolio to show.
Along with the results of each mini-experiment, you should have a page or half page which summarizes and explains the basis and findings of the experiments.
The last page of your portfolio should summarize the collection of experiments and try to make connections between them.
