Matter, Atomic Structure, and Bonding: Flame Tests

We began Chapter 4 with the Flame Test lab.  We reviewed the safety requirements and lab mechanics.  There were stations set up around the room with portable Bunsen burners, chemicals to burn, and equipment to conduct the flame test.  Students recorded their results as described on the Lesson 17 Worksheet.  Students were also offered 10 points of extra credit for taking video of the flame tests and editing them together into a video.  Students also received a print-out of the electron structure of a sodium atom, showing what happens when the outer shell electron of sodium is excited.  The lab took most of the class period, so we will discuss results tomorrow.  Students should complete as much of the Lesson 17 worksheet as possible, read Lesson 17 in the textbook, and answer questions 1 and 2 in the textbook.

Cells & Homeostasis: Assemble PBL Posters

Student groups received their printed Google Doc materials and a used tri-fold poster board.  They were provided with Pirate yellow paper to re-cover the tri-folds and then began sketching out how their content would be attached to their boards.  The process helped students identify remaining areas of need so they can focus their efforts on Thursday, our final class day in a computer lab.  The pictures below show an example tri-fold layout for students who need some inspiration and guidance, as well as a list of goals for the rest of the week.
