The portfolio will be in an assessment (kind of like tests normally are) on the last page of this lesson. You will need to have 2 windows open to do this, one for the 'Water Quality Analysis Website' activity on page 3, and one for the assessment on the last page. So when you get to the activity, open it in a new tab so you can have both open at the same time. You do NOT need to fill out the worksheet on page 3! If you see a page that says 'your teacher has dropped this assessment,' click to the NEXT page to complete the lab (it has not been dropped!)
