PHYSICS Lesson 1.2: The Methods of Science Objectives: At least 80% accuracy, SWBAT 1) define science and identify its branches, 2) identify in the correct order the steps of the scientific method, and 3) apply and recognize steps in a given experiment scenario. The Methods of Science An example of the Scientific method: What is Science? Let's say I have a problem: My car won't start. How 1. studies the __natural world__________________ would I use the scientific method to solve this problem? 2. discovers __knowledge______________________ 3. discovers nature's "__rule____" about how things Problem/Question: work 4. only deals with natural phenomena and natural causes excludes __supernatural______________ Observation/Research: Branches of Science 1. _Life science___________(biology, microbiology, Construct Hypothesis: botany, evolution) - deals with living things 2. _Earth science________ (geology, meteorology) - earth, space, rocks, volcanoes, weather Experiment and Materials: 3. Physical science__________ (chemistry, physics) - matter, energy, gravity, light, sound Why Study Physics? Physics is a branch of science that describes the motion Results: and energy of all matter throughout the universe. What is the Scientific Method? Conclusion: • The scientific method is- – A logical and systematic approach or process to problem solving. – An organized way of using evidence to learn Suppose the car still doesn't start? about the natural world. Steps in the Scientific Method Observation/Research: Develop a question or problem Problem/Question that can be solved through Observations can experimentation Sometimes be done Construct Hypothesis: Observation/Research Make observations and by using one or more of the five senses. research your topic of interest. An “Educated” guess of an Think! Construct Hypothesis Experiment and Materials: answer to the question Try Again Develop and follow a procedure Experiment/Materials designed to test the hypothesis. Include a detailed materials list. Results: Analyze Results/ Draw Conclusion Hypothesis is False Conclusion: or Partially True Hypothesis is True Report Results PHYSICS Classwork 1.2: The Methods of Science Name: ________________________________ Period: _____ Date: _____________ Score: _______________ Objectives: At least 80% accuracy, SWBAT 1) define science and identify its branches, 2) identify in the correct order the steps of the scientific method, and 3) apply and recognize steps in a given experiment scenario. Using your Fall Buddies, pick a question and Design an Experiment 1) What is the best material for insulation? (wool, leather, etc.) 2) Will human urine repel sharks? 3) Does the color red make lizards more aggressive? 4) Will fish grow larger if placed in a larger tank? 5) Does exercise reduce the risk of heart attack? 6) Does aspirin keep cut flowers fresh longer? .
