Biology - HOT Science Lab

Teacher
After
activity:
that temperature is not too cold (near zero o C or too hot, above 42 o C)
5. What could happen if you handled the paper holes with your hands and
not with forceps Is this lab a quantitative or a qualitative lab
6. What is the function of keeping all objects as clean as possible before
touching the bacteria
b. Provide expectations during Observations, Data Analysis, and Results:
1. Ask and answer questions during the lab to promote student
assimilation and understanding of lab ideas and scientific concepts.
2. Draw the circle of inhibition for each agar plate in the data table.
What the teacher will do:
a. Design questions to engage student thinking after activity. (e.g., Are there
differences in the effectiveness of microbe inhibitor in killing bacteria for
each disk How can you tell that bacteria were killed or that the bacteria
survived
b. Provide directions (expectations) for student writing of lab/activity, “Parts of
a Lab Report” or “Power Writing Model 2009”
c. Assess student understanding by discussing factors that keep bacteria
population in control. (Ask students to write several factors that prevented
the bacteria population from increasing exponentially and thereby leaving
the Petri-dish).
