1. Catalyst (Left Page) Observations & Inferences Make at least 5 observations about the picture on the left & set up your Cornell notes.

2. Observations & Inferences Set up your Cornell Notes for today’s notes (right page)! Observations & Inferences 08.26.2008

3. How is Science is a Process? Scientists ask questions about how the world works We discover pieces of the answer What we know CHANGES

4. How is Science is a Process? Science = Process - Scientists ask question, discover pieces of answer - What we know changes

5. Scientific Inquiry Way for scientists to answer all those questions about the world Way to investigate an observable event and getting new knowledge, as well as for correcting and integrating previous knowledge

6. How is Science is a Process? Science = Process Scientific Inquiry - Scientists ask question, discover pieces of answer - What we know changes - Way to answer questions & investigate observations

7. Scientific Inquiry Make an Observation Ask a question Construct a Hypothesis Test the Hypothesis Analyze the Data Draw a Conclusion

8. Make an Observation Ask a Question Construct a Hypothesis Test the Hypothesis Analyze the Data Draw a Conclusion

9. Observations vs. Inferences Science = Process Scientific Inquiry - Scientists ask question, discover pieces of answer - What we know changes - Way to answer questions & investigate observations - a.k.a. scientific method

10. Observation Information you gather using one of your five senses Factual information that describes an object

11. Observations vs. Inferences Science = Process Scientific Inquiry Observations - Scientists ask question, discover pieces of answer - What we know changes - Way to answer questions & investigate observations - a.k.a. scientific method - Information using @ least one of the senses - FACTS (sight, sound, touch, smell, taste)

12. Observations The plant is green. The piece of metal is orange. It is raining outside. The car alarm is beeping. The wall has cracks in it. The room feels humid.

13. Observations vs. Inferences Science = Process Scientific Inquiry Observations - Scientists ask question, discover pieces of answer - What we know changes - Way to answer questions & investigate observable event - a.k.a. scientific method - Information using @ least one of the senses - FACTS (sight, sound, touch, smell, taste) - Examples: 1. The plant is green. 2. The car alarm is beeping.

14. What do you observe in the classroom? In your notebook (left side), make 5 observations about the classroom Remember, observations use one of the five senses: –Sight- Taste –Hearing- Smell –Touch

15. Inference A conclusion drawn using observations and reasoning NOT a fact you can detect using one of the five senses An explanation

16. Observations vs. Inferences Science = Process Scientific Inquiry Observations Inferences - Scientists ask question, discover pieces of answer - What we know changes - Way to answer questions & investigate observable event - a.k.a. scientific method - Information using @ least one of the senses - FACTS (sight, sound, touch, smell, taste) - Examples: 1. The plant is green. 2. The car alarm is beeping. - Conclusion/explanation from observation & reasoning - NOT FACT

17. Inferences The table looks like it is made of wood. The piece of metal is red, so it must be hot. The plant is green, so it must be healthy. The room is dark, so the light bulb must not be on. Andrea is studying, so she probably does well in school. The street is wet, so it must have rained.

18. Observations vs. Inferences Scientific Inquiry Observations Inferences - Way to answer questions & investigate observable event - a.k.a. scientific method - Information using @ least one of the senses - FACTS (sight, sound, touch, smell, taste) - Examples: 1. The plant is green. 2. The car alarm is beeping. - Conclusion/explanation from observation & reasoning - NOT FACT - Example: 1. The piece of metal is red, so it must be hot.

19. Influences Several things can influence our observations and our inferences –Experience –Knowledge –Emotion –Attention to detail.

20. Observations vs. Inferences Observations Inferences Influences - Information using @ least one of the senses - FACTS (sight, sound, touch, smell, taste) - Examples: 1. The plant is green. 2. The car alarm is beeping. - Conclusion/explanation from observation & reasoning - NOT FACT - Example: 1. The piece of metal is red, so it must be hot. - Experience, knowledge, emotion, detail attention affect observations/inferences

21. Example I observe that I see a swimming pool I observe that my dog feels wet I infer that my dog jumped in the water

22. Example I observe that Nick is yawning I observe that Nick has his head on his desk I infer that Nick did not get enough sleep last night

23. OBSERVATIONS That plant is extremely wilted. The car stopped running INFERENCES That plant is extremely wilted due to a lack of water. The car stopped running because it was out of gas.

24. Observations vs. Inferences Inferences Influences Obs. Vs. Inf. - Conclusion/explanation from observation & reasoning - NOT FACT - Example: 1. The piece of metal is red, so it must be hot. -Experience, knowledge, emotion, detail attention affect observations/inferences The car stopped running. (Obs.) The car stopped running b/c it was out of gas. (Inf.)

25. Observation or Inference? The child has a blue block

26. Observation or Inference? The child playing with the car is smiling.

27. Observation or Inference? The child is happy because she is playing with a car.

28. Observation or Inference? The grass is wet, so it must have rained last night.

29. What do you observe? In your notebook (left page), write 3 observations

30. What do you infer? In your notebook (left page), write 3 inferences based on your observations

31. Draw an inference. You hear a yell. You hear a crash. You walk into the next room and see a baseball on the floor next to a broken lamp. What do you infer (left page)?

32. Go back to the 5 observations you made in your catalyst –Were your observations purely observations? –Did you have any that were actually inferences? How do you know?

33. Summary Take 3 minutes to work on your summary
