How would you separate a cup of oil and water? of sand and gravel? of lead and aluminum pellets? Well you start by knowing the physical properties of the substances. Students faced these and other situations today in class as we discussed the process of separating mixtures, both homogeneous and heterogeneous. Students worked in pairs to complete this activity on worksheet 3-2. Upon completion and review, we discussed the remaining vocabulary in section 3-1 notes, followed by an open discussion on technology issues in science class.
No homework was assigned.
