Unit 1: Engage Review
Also: Testing Norms and
Procedures
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

Review Quiz #1
Manipulated Variable
Responding Variable
Hypothesis
Rational
Control Variables
Experimental Groups
Control Groups
Lab 1-1: Roly Poly’s
• Carrying out the scientific process
• Scientific Process
– Observe carefully
– Question / Hypothesis
– Experiment and collect data
– Look for Patterns
– Draw conclusions
Lab 1-2: Becoming a Keen
Observer
• Apple Lab
• Carefully observation
– Qualitative
– Quantitative
• Observation vs. Inference
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
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
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
• Variation arises through random mutation
– Mutations are not responses to the environment
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
Journal 1-5: White Clover
• Real world example of Evolution by
natural selection and the scientific
process
– Populations of clover evolve not individual
clovers
