Chemistry 1 – Earlier this week we looked at boiling, melting, and freezing of water individually. Today we put it all together into one big Temp vs. Time graph. In class I showed and how to analyze the Energy storage category at a point on the graph. Because energy is being added to our system throughout this process we need to include an “Energy Flow” modeling this increased energy. The above is a final product after analyzing all point along the graphed line. This serves as a great way to introduce the usefulness of Energy Bar Graphs to track energy in a system. (BTW, I used an app called AirSketch that allows me to write on my iPad and project it through the computer.)
Physics 1 – Student groups completed work on the box on a ramp problem I showed yesterday. I then gave individuals a “Checkpoint” assignment. It was like a mini-quiz, but I didn’t want to call it a quiz. I will be able to analyze how the students did on the problems to guide the classes next week.
Chemistry 2 – Groups continued to work on, and hopefully finished, their Organic Functional Group Wiki project. It’s due on Monday.
