Physics: Closed Pipes

Students whiteboarded their results from yesterday’s lab and we discussed the results. Afterward, students started working on finding a relationship between wavelength and the length of an air column needed for a standing wave, using the speed of sound from the video to get the wavelength of a tuning fork.

Chemistry: Percent Yield

I introduced the concept of percent yield and students started working through some problems. They also took a quiz on stoichiometry, which didn’t go as well as I hoped. Looking at their work, I think a lot of students lost track of what all the different numbers mean, so I’m tweaking some lessons for later this week to try and get back to the physical meaning of the numbers they are using.
