We corrected yesterday's worksheet.
Students then used petri dishes with agar to test the effectiveness of two types of disinfectant. Students swiped their fingers across table and swiped Section A, B, and C. In A they placed two drops of Lysol and in B they place two drops of a "green disinfectant. C is the control.
Students must write a prediction on the back of their paper explaining which disinfectant they think will work and why.
Reminder: Wanted posters are due on Monday!
