Grade 7 & 8 - study for the test
Grade 9 - continue work on your investigation. Now you have the data, plot a graph/graphs to show how the current and voltage change with time. There is a help sheet on the blog which reminds you of how to process graphs using googlesheets. Remember to add a line of best fit using Paint, and then copy/paste the graph AND the results (use the snipping tool on the spreadsheet) into your report.
