Physics: Speed of Sound

After some time playing with the wave generator to confirm Thursday’s lab results, students used a Direct Measurement Video to produce a position vs. time graph and find the speed of sound. Tomorrow, they’ll put that speed to use in closed pipe resonators.

Chemistry: Speed Dating

Students needed just a little more practice to firm up their stoichiometry skills, so we did some whiteboard speed dating with problems similar to what will be on tomorrow’s quiz. I was really pleased at the number of groups who were really talking through problems , taking turns with the marker, and taking other steps to ensure that both students really understood what was going on.
