**Physics: Standing Waves**

Students used a Direct Measurement Video to look for patterns in the wavelengths and frequencies that can produce a standing wave on a string. I’d set up the wave driver this morning to try some ideas for Monday, and several students asked if they could try it to answer some questions the videos raised for them, but didn’t have a great way to answer.

**Chemistry: Stoich Practice**

Students finished up their stoichiometry practice problems today. I’m trying to really focus conceptually on what the math means, so we spent some time drawing repeated reaction diagrams to better connect the math to the lab they did a few days ago.
