Every lab in this course. Each page has the same shape:

Purpose → Safety → Materials → Procedure → Data → Analysis → Hand in

Read the whole page before the class it belongs to. The safety section is not optional reading.

Before every investigation

Goggles, tied-back hair, closed-toe shoes. If you are missing any of the three, you will be doing the written alternative instead.

Format for the write-up: Writing a Lab Report. Seven of these investigations are written up for marks — Lab Reports says which seven, which period each is written in, and what the write-ups are judged against.
