Chemistry 1 – Today was spent discussing and analyzing the volume and mass models groups put on boards yesterday. Each group described their data in four ways; verbal, pictorial, graphical, and mathematical. Much of the discussion today revolved around the verbal and pictorial (particle diagrams). There was also talk about how the graphs showed that each color object was made out of different material. The idea of the slope of each line gave us a ratio was our indicator for this. Where we left off was whether we should be graphing V vs. m or m vs. V. Tomorrow should help us decide.
Physics 1 – After working through some problems involving multiple models of motion (x vs. t graph, motion map, written description) yesterday on paper groups were assigned to put one of the problems on a whiteboard. There were two groups assigned to each problem and those groups proceeded to have a “Whiteboard Face-off.” This face-off consisted of each group explaining the solution they came up with, and trying to “win over” the rest of the class as to which solution/board/representations/wording was better.
NOTE: This is similar to Kelly O’Shea’s Whiteboard Face-Off, but with only two groups instead of the whole class.
Chemistry 2 – Students finished up their Unit 9 assessment. I then introduced them to their final project for the class, because I want them to start thinking about what they are going to do. The final project requires them to come up with some chemical demonstration that they can perform, and then more importantly, explain. At minimum this demo will be performed and explained for the class, but could also be done for Elementary or Middle school students as well.
