Because we are performing this lab asynchronously and entirely online, here are supplemental instructions that go with the lab (contains some additional video examples).

You will not be able to fill out all of this lab as shown in the Workbook pdf download.  You may omit the tests and observations that are not available in the video.

Be Well & Good Science,
