Be sure to turn in your review questions

Scientific Method Notes and Practice 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 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
