Day 27 – Density Model

Chemistry 1 – After an class hour+ of discussion we were finally able to wrap up our discussion on how mass and volume of objects are related.  Through the use of multiple models we were able to arrive at the fact that everything we are describing has to do with the concept of DENSITY.  The main thing we were able to conclude today was that if we look at mass vs. volume graph the slope is the density.  From there we looked at why the D=m/V model works.

Physics 1 – Another round of Whiteboard face-off.  Today we faced-off with problems about two bicyclists riding at different velocities in a) the same direction and b) different directions.  Students were given graphical x vs. t models and asked questions based on that model.  This generated some good discussion about exactly how to interpret a few things about x vs. t graphs.

Chemistry 2 – We took some qualitative observation data on how 7 different unknown solutions reacted with 5 test reagents.  The goal tomorrow is to classify these solutions based on their reactions.
