I am SO sorry for the delayed post! Here is the homework due tomorrow, the homework due Friday, and today and tomorrow’s PowerPoints.
Reminder: We’re taking our diagnostic test AND our quiz on Friday. The quiz will be on the material covered on Wednesday and Thursday (see attached PowerPoints).
Today in class you tested 5 different substances for 3 properties: whether they’re magnetic, whether they float, and whether they dissolve in water. Tonight for homework, you need to write out a step-by-step procedure for tomorrow’s Separation of Mixtures Lab. You need to come up with a detailed plan for how you’re going to separate a mixture of salt, sand, black pepper, pebbles, and iron filings. Write your procedure on the next blank page of your science notebook, and include a list of all materials you’ll need.

Make sure you study the LAB EQUIPMENT and SAFETY RULES for tomorrow’s quiz!!! I’m attaching the powerpoint I used when we played the Lab Equipment game in class. It has a bunch of big pictures of different pieces of lab equipment.
