11/14 diffusion LAB


In-Class:
Students completed the 10 point organelle quiz. First hour students will take this quiz tomorrow, Thursday.

LAB - Diffusion of food coloring through 200 ml of water. Students used their powers of observations to note the diffusion. We also worked as a class to come up with variables that would alter the outcome of the lab. The write up is due IN BIN Thursday. Any student not present in class can complete the lab at home with one cup of water in a clear glass and 3 drops of food coloring. Students who were absent from first hour due to the honors breakfast are excused from the lab but may want to reproduce the lab at home for fun.

Homework:
Review pp. 5-37 in text.
