1. What does abiotic mean? Give an example of an abiotic factor in the classroom.

2. What does biotic mean? Give an example of an biotic factor in the classroom.

1. Where in a conclusion do you state whether the hypothesis was supported or not?

2. What do you do in the commentary of a conclusion?

• Unit 2 Quiz on 10/6• Use the Unit 2 Divider as a study guide• Scientific Method:

• Observation -> Curiosity -> Question -> Hypothesis -> Experiment ->Analysis -> Conclusions

• Qualitative and Quantitative observations

• Experimental Design:• Validity, reliability, accuracy, precision• Know the three kinds of variables, what a control group and

trials are, the elements of a good experiment• Know the different kinds of graphs and what data they are

used for• How to write a conclusion (the 4 parts and what they

include)

• The Characteristics of Life• Know the 7 characteristics of life• Know how a living thing must be able to do them (Hint:

Independently or Cooperatively)

1. Create a graph of you and your partner’s data.

2. Did each person’s reaction time increase or decrease with the addition of the MV?

3. Get checked off.

Sheep Dash - Analysis

• TS: Hypothesis supported or not, answer investigative question

• CD: Highest average time• CD: Average time• CD: Lowest average time• CM: Relationship between MV & RV• CS: Scientific explanation for this

relationship• Get checked off
