Students whiteboarded their solutions to yesterday’s problem. In my class of 15, I had students present while in my class of 35, I tried a gallery walk, instead. I really liked the gallery walk with the big class; it gets hard to hear from everyone with that many people in the room, so talking about each board in smaller groups made it possible for more students to both ask and answer questions.
Chemistry: pH Lab
Students did a lab to find the pH of household chemicals. Students did a nice job of connecting the properties of each chemical to the properties of acids and bases.
