Today we did a lot of different things. We started off reviewing solutions (homogeneous mixtures) and suspensions (settle over time and need to be shaken). Then we watched a Brainpop about chemical and physical properties. After finishing the movie, we had a little contest to see who could correctly identify whether a characteristic was a chemical or physical property or change. Cassidy, Ashleigh, and Kelsey got all of them correct!

We did another small contest seeing if students could identify the difference between substances and mixtures. If it was a substance, then it had to be classified as an element or compound. If it was a mixture, then it needed to be classified as homogeneous or heterogeneous. Patrisha won that contest as a team of one - go Patrisha!

Then we covered some notes on heat, endothermic and exothermic, and the difference between specific heat and heat capacity.

We finished the class with a game of SWAT! Students had to identify parts of the phase change diagrams by swatting the part of the graph that answered the question I asked. This also helped a few students who were having trouble with the graph. The right side team (I think Yellow) won by only one point.

Students will be doing a calorimetry lab tomorrow to measure specific heat and have a Unit 1.5 Test on Friday.
