  1. Date: 8/11 &12 Lesson Title: Observation vs. Inference DO NOW ACTIVITY (D.N.A) • 1.) As scientists, why do we perform experiments? Write down 3 observations you can make about this classroom? • 2.) Look at the image below. Write down what it is, and how you know.

  2. DO NOW ACTIVITY (D.N.A)

  3. HOMEWORK IN/OUT • Observation vs. Inference Worksheet • Lesson Notes • Date Assigned: 8/11 &12 • Date Due:8/13 & 14 OUT • Exit Ticket IN

  4. MISSION • SWBATdifferentiate between qualitative and quantitative observations and make inferences based on observations.

  5. WHAT IS SCIENCE?

  6. WHAT IS SCIENCE? Science is a system of knowledge and about the specific methods you use to find that knowledge. ...it begins with CURIOSITY and often ends with DISCOVERY

  7. LETS LOOK AT THE BIGGER PICTURE • 1.) Make Observations • 2.) Determine a problem • 3.) Form a hypothesis • 4.) Collect & Record Data • 4.) Conduct Experiment • 5.) Analyze Data/Conclusion

  8. Before we get started... • SHOUT OUT WHATEVER OBSERVATIONS YOU NOTICE...

  9. Information you gather using your five senses Factual information that describes something Key Term #1: Observation

  10. OBSERVATIONS

  11. **These are observations because it is information obtained directly through senses!** EXAMPLES OF OBSERVATIONS

  12. An INFERENCE is an assumption or a prediction made from observations Key Term #2: INFERENCE

  13. **Is an assumption that cannot be directly observed with the senses** EXAMPLES OF INFERENCES

  14. BACK TO THE DEMO • WERE THOSE OBSERVATION, INFERENCES or BOTH? • (*Try to use examples of what you said)

  15. LETS PRACTICE!!

  16. IN YOUR GROUPS... Hamburgers 200 People Cotton Candy What are your inferences? (Write your answer in your guided notes, be ready to share) Popcorn

  17. Look at these two sets of animal tracks and on your guided notes... • List 3 Observations • Make an Inference FRAME #1

  18. FRAME #2 List 3 Observations Make an Inference

  19. FRAME #3 List 3 Observations Make an Inference

  20. WHAT WERE THE TWO CATEGORIES THAT ALL OBSERVATIONS FALL UNDER? Back to OBSERVATIONS • QUALITATIVE or QUANTITATIVE

  21. ... ARE MEASURABLE OR COUNTABLE Key Term #3:Quantitative Observation

  22. EXAMPLES OF QUANTITATIVE

  23. Describable not measurable Key Term #4:Qualitative Observation

  24. EXAMPLES OF QUALITATIVE

  25. Let’s Practice 1 2 3 4 5 6

  26. What’s in the bag? (10mins) • In the classroom you will notice that there are 5 separate “Mystery Bags”. One at each table. • As a group, you will have 2 minutes to feel what is inside the bag and make 2 observations about what you feel. Then, you must infer what is inside the bag. • You will rotate every 2 mins until each group has been to all 5 stations

  27. EXIT TICKET • Time: 5 mins • Trade & Grade (CB: First & Last Name) • Once Graded: • Put Score on Guided Notes
