1Please get your science notebook from off the table before we start class. Seat down in your seat and turn to the warm-up section (back of book). On the first line write: August 11 – Animal Tracks
2Observations Any information collected with the senses. Quantitative – measureable or countable3 meters long4 marbles50 kilograms35 degrees CelsiusQualitative – describable, not measureablered flowerssmells like fresh baked cookiesTastes bitterThe skill of describing scientific events
3Inference Conclusions based on observations. The process of drawing a conclusion from given evidence.Practice:Observations:I hear people screamingI smell cotton candy, popcorn, and hamburgersI see a lot of peopleInference = ?
4Look at these two sets of animal tracks. List 3 OBSERVATIONS Warm-Up August 11Look at these two sets of animal tracks.List 3 OBSERVATIONS(What do you see?(Write it down next to the heading.)August 11 – Animal TracksObservations: 1)2)3)Inference:Make an INFERENCE(What do you think happened? Write it down.)
5Now what do you think happened? (Write it down.)Make 3 OBSERVATIONSMake an INFERENCE
6Now what do you think happened? Did your revise (change) your original inference?How did seeingthe whole image change your mind?How does this activity relate to what a real scientist does in an experiment?
7Earth Science Rocks! Opening: Scientific Method Rap MYP Unit Question: Why Science?Area of Interaction: Approaches to LearningLearner Profile: InquirerOpening: Scientific Method RapLearning Target: Today I’m learning about the Scientific Method because it is the process of investigation.Work Session: Notes – Scientific MethodClosing: Luck of the Draw - Scientific Method Review
8The Scientific Method 1. Turn to your table of Contents page. 2 The Scientific Method 1. Turn to your table of Contents page. 2. Write “Scientific Method Notes” next to #4. 3. Turn to page 4 and write “Scientific Method Notes” as the heading.
9Standards S6CS8. Students will investigate the characteristics of scientific knowledge and how it is achieved.S6CS9. Students will investigate the features of theprocess (procedure) of scientific inquiry.
10The Scientific Method The scientific method is the only scientific way accepted to back up a theory oridea. This is the method on which allresearch projects should be based. TheScientific Method is used by researchersto support or disprove a theory.
11PHEOC The Scientific Method The Scientific Method involves 5 steps: ProblemHypothesisExperimentObservationConclusion (Result)PHEOC
12The Scientific Method Problem- You ask a question about what you observe.
13The Scientific Method Hypothesis- You predict what you think the answer to your question mightbe.
14The Scientific Method Experiment- You figure out a way to test whether thehypothesis is correct.The outcome must be measurable.Record and analyze data.
15Controlled Variable:Something that you don’t change.Dependent Variable:Something that you measure.Independent Variable:The object you experiment with.
16The Scientific Method Observe - You do the experiment using the method you came up withand record the results.
17The Scientific Method Conclusion- You state whether your prediction was confirmed or notand try to explain your results.
18Scientific Method Review Closing:Scientific Method ReviewSee if you can identify the steps of the Scientific Method in the following scenarios.Work with your lab group.Don’t yell out the answer;raise you hand instead.
19Scenario 1Peter loves music. He believes that he does his homework better and faster when he listens to music. His parents say that music is distracting when studying.What is the problem?Create an hypothesis.How would you test your hypothesis?
20Scenario 2 The Johnson family has decided to try to save electricity (and money at the same time). They were told that they couldreplace their regular light bulbs with special fluorescentbulbs that use less energy. They wonder if it is really worthdoing.What is the problem?Create an hypothesis.How would you test your hypothesis?
21Scenario 3Kelly and Jack are playing in the park. Jack rolls a marble down the small playground slide. Kelly rolls a marble down the large playground slide at the same time. They noticed that Kelly’s marble reached the ground first. They rolled the marbles again and noticed that the same thing happened.What is the problem?Hypothesis?How would you test your hypothesis?What would by your Controlled Variable? (What you would keep the same?What would be your Dependent Variable? (What would you measure?)Why does one marble roll faster than the other one?Roll both marbles down the slide atthe same time.Size of the marbles, same slide, roll at the same time.The time the marbles reached the ground.
