I handed back papers and labs today and we had a discussion about what makes a good scientific conclusion. I read a few of the excellent conclusions I received.
We talked about the Law of Conservation of mass and how matter cannot be created or destroyed. If you burn a log, the mass of all the ashes, smoke, gases, and everything that is burned off and left behind EQUALS the mass of the original log.
Today students discussed physical vs. chemical properties and changes. They've heard all of this before I am sure, but it doesn't hurt to go over it again. Then we did a challenge to see if they really knew their stuff. In second period, Kaboria earned a perfect score and a pair of star sunglasses. Jasmynne, Jessie, and Laura only missed one of the 36 possible points. Awesome! In third period, there was a 3-way tie for first place with 34 points between Corrin, Delafayette, and Riley and Riley won the star glasses! Second place was a tie between Sabrina and Dara.
We finished class with a discussion about solids and liquids.
