Also: Testing Norms and Procedures

2. Testing Norms and Procedures
Take your assessments seriously
Tests/Exams/Quizes start at the beginning of the block
No time for questions
No extra time will be given if you cannot make it to class on time
Let me know of any accommodations
Standard expectations
No talking
Raise your hand if you have a question, etc..
Be sure to turn in your review questions

3. Scientific Method Notes and Practice Questions
Review Quiz #1
Manipulated Variable
Responding Variable
Hypothesis
Rational
Control Variables
Experimental Groups
Control Groups

4. Lab 1-1: Roly Poly’s Carrying out the scientific process
Observe carefully
Question / Hypothesis
Experiment and collect data
Look for Patterns
Draw conclusions

5. Lab 1-2: Becoming a Keen Observer
Apple Lab
Carefully observation
Qualitative
Quantitative
Observation vs. Inference

6. Journal 1-1: Lucy and Journal 1-2: Modeling Earths History
Organisms have changed over time
Earth is really, really old
Scientists have built a historical timeline by following the process of science.
Careful observation of fossils
Logical Inference

7. Journal1-3: Learning about Natural selection
How do organisms change over time?
Natural Selection
Key point: Natural Selection acts on populations not individuals.
OCVSRS = natural selection
Be able to relate to other scenarios
Natural vs. artificial selection

8. Lab 1-3: Bacterial Antibiotic Resistance
Key Point: Bacteria have resistance to antibiotics. (Not the other way around)
Variation exist within bacterial species
Ex. E. Coli = species
Ability to grow in the presence of antibiotic = variation

9. Variation arises through random mutation
Mutations are not responses to the environment

10. Journal 1-4: Evolution in Action
O = bacterial populations grow exponentially
C = bacterium are limited by space and available food
V = some bacteria have antibiotic resistance
S = in the presence of antibiotics, resistant bacteria survive
R = surviving bacteria reproduce
making a resistant strain
Causing antibiotic to be ineffective

11. Journal 1-5: White Clover
Real world example of Evolution by natural selection and the scientific process
Populations of clover evolve not individual clovers
