SCIENTIFIC METHOD The Scientific method can be applied
SCIENTIFIC METHOD The Scientific method can be applied to ANY testable questions! NOT JUST SCIENCE QUESTIONS!
ANY TESTABLE QUESTION!! friend or y o b y m ’t Why didn class? r e t f a e m t ee girlfriend m Why is there so much tr affic aro in the m und 7: 0 orning? 0 Why doe s an i. Pad block cha an i.

SCIENTIFIC METHOD SORT 1. With your • Share/Communicate group, put the Results following steps • Test hypothesis in “order” • • • Draw conclusion Form Hypothesis Research/Gather Info Collect & Analyze Data State Problem (based off observation)
https: //www. youtube. com/watch? v=_7 s. Suh. Q 1_24 Big Bang Theory S c i e n ti fi c Me th o d Leonard made an observation and proposed a question Designed/Tested the experiment “Where should we go eat? ” Further Research Sheldon tested the hypothesis They came to a conclusion He relates everything back to the space center FOR EXAMPLE Formed a Hypothesis. If I ask Wolowitz a question, then he will relate it back to the space center
THE METHODS OF SCIENCE Science Hypothesis Is a process that uses observation to gain knowledge about the world around us educated guess or testable prediction Format: If I do (independent Variable) , then (dependent variable) (will happen), because ____. Experiment A procedure to validate or refute a hypothesis
FOR EXAMPLE Observation: My boyfriend (or girlfriend) did not meet me after class Hypothesis: Hypothesis If I take the long way to the gym then my boyfriend (or girlfriend) won’t meet me after class, him/her late. because it will make Experiment: Take the normal way to the gym, take a short route to the gym, and take a long route to the gym
IN EXPERIMENTS YOU WILL HAVE VARIABLES Independent Variable Part of an experiment that is purposely changed Independent – I changed Controlled Variables & Control Group The part sof the experiment that remains the same in both groups Dependent Variable Part of the experiment that is observed and or measured
EXPERIMENT CONTINUED Independent Variable: The route I took to the gym Dependent Variable: Variable the amount of time it took to get to the gym Control: used for comparison The normal route taken Constants or Controlled variables : the location (school), my mode of transportation to the gym (I walked. . Didn’t run…skip…hop…skateboard)
PRACTICE!! You water three sunflower plants with salt water. Each plant receives a different concentration (amount) of salt solutions. A fourth plant receives pure water. After a two-week period, the height of the plants are measured. Ind. Variable amount of salt in solution Dep. Variable height of the plant Control Group (or variable) plants receiving water only
Scientific Method Card sort Do you need to rearrange anything? 1. State Problem (question) (based off observation) 2. Research (to become educated) 3. Form a hypothesis (educated guess) 4. Test Hypothesis (Experiment) 5. Gather and Analyze Data (Was your hypothesis right or wrong? ) 6. Conclusion
HYPOTHESIS LEAD TO THEORIES 1. Hypothesis is an educated guess or testable question 2. Theory is a well tested hypothesis that has been repeatedly verified 3. Law is a summary of multiple theories that describe patterns in nature
