Today, we started class by writing a notecard for Activity #15 analysis question #3. We also worked on vocabulary for Activity 15.
Then, for the rest of class we did Part 1 of Activity 17. This was a lab where we poured BTB color in cup A, B, C, D, E of a setup tray.
Then we blew air from a dropper into cup B...
...and then with cup D and E we blew into the BTB with a straw.
BTB turns from blue to green to yellow when CO2 is added. We then recorded what happened to the BTB in each cup on page 21 of our science notebook in the table.
We will finish the rest of the Act 17 tables next class.
