11/29 - Biology

Took attendance

Welcomed the students and let them know what to expect for the week.

Introduced myself using the welcome ppt.

Had the students work in pairs and used the "get to know you in 60 seconds" handout. Each person asked random questions for 1 minute. Then switched. Had each person introduce the other person to the class.

Started the bubble gum lab.
Did the bubble gum lab.

1. Handed out the lab sheet.

4. Had one student read the 2nd problem out loud.
5. Within their small groups, the students discussed and wrote down their hypothesis.
6. I asked to disclaimers: Can any student not chew gum? Does any student get sick from the site of chewed gum?
7. Told the students to not do anything with the gum but take a piece and pass the rest around the room.
8. Go through the procedure with the class and show them the data table.
9. Talk about the initial weight and what that represents (control) and why that is important.
10. Explain that I will keep the watch and we will all do it together. When they are done weighing they are to turn and face me so I know when we can move on.
11. Tell them that they are to weigh their gum on their wrapper so they keep the gum clean.
12. Show them how to use the scale (zero it everytime and don't put anymore weight then neccessary).
13. Follow the table with timing and get to work.
14. Can't finish the last question if the averages are not given in class.
15. Finished with taking data.
