**Review Topics for Unit 1 Test** **Mr. Herbstritt - Biology 106** **MODULE 1 or 2** **Scientific Method** 1. Be able to outline steps of the scientific method - Observation: Notice something interesting or a phenomenon that sparks curiosity. - Question: Ask a specific question about the observation you made. - Hypothesis: Form an educated guess or possible explanation for the observation, which can be tested. - Experiment: Design and conduct a controlled experiment to test the hypothesis. - Analyze Data: Collect and interpret the results of the experiment. - Conclusion: Summarize the findings and state whether the hypothesis was supported or rejected based on the data. 2. Be able to distinguish between Experimental and Control Groups in experiments **An experimental group is the group that receives the variable being tested in an experiment. The control group is the group in an experiment that does not receive the variable you are testing** - Experimental Groups: Groups of organisms with the Ind variable - Ie- Current vaccination trials -- Yes vaccine people - Control Groups: Groups of organisms without the Ind Variable - Ie- Current vaccination trials -- No vaccine people - Not always control group - Ind Variable: Vaccine - Dep Var: Effectiveness of the vaccine - Controlled/standardized variables. - Method of vaccination - Exposure to Covid 19 3. Distinguish between independent, dependent and controlled/standardized variables - Independent Var - [Cause]. It is the manipulated variable (by the researcher) Therefore, the researcher always knows the Ind var BEFORE THE EXPERIMENT - Dependent Variable - [Effect] It is the Responding/measured Variable because you don't know this result until you DO the experiment **Life Characteristics and Organization** 4. List characteristics of living organisms. (See powerpoint and/or book) - Organization - Energy Use - Internal constancy - Reproduction and development - Evolution 5. Distinguish between consumers, producers, detritivores, and decomposers in ecosystems - Producers: Plants and other organisms that do photosynthesis and make their own food - Consumers: Non-plants (mostly animals) that depend on producers for food - Detritovores: Eat dead organisms - Decomposers: Fungi and bacteria
