1. Chemistry – Sept 25, 2017
Do Now – Get out your prelab flowchart and procedure for homework check and collect the first materials you will need for your separation strategy, including safety goggles and a balance. You will receive your sample mixture to separate after I have checked your prelab.
Hints:
iron is magnetic but none of the others are
salt dissolves in water but none of the others do
in water, poppies float, but iron and sand sink
Don’t add water until you really want to, and use a limited amount, because you’ll just have to boil it away later.

2. Objectives and Agenda Objectives
