4 Content background (systems understanding) is crucial to asking good questions

5 What is a system?

6 What is a System?

7 An assemblage of inter-related parts or conditions through which matter, energy and information flow. (WA EALRs) An organized group of related objects or components that form a whole. (NRC) A collection of things and processes that interact to perform some function. The scientific idea of a system implies detailed attention to inputs and outputs and interactions among system components. (AAAS) (Field Investigation Guide, pg 1 and pg 77.)

8 Go outside and observe the local system: Draw and label parts of the system. Local System

9 What were the parts of the local system? Local System

10 Tree (conifer) Bush Sidewalk Bare Ground Car Building Air Decaying leaves Tree (deciduous) Urban Ecosystem

11 Types of Questions Investigation Questions Essential Questions Systems Questions Look in a book- Questions Life- Pondering Questions Why Questions

12 We want to ask students systems question: Function of parts Energy forms and transfers Roles of parts in ecosystem Interconnections in ecosystem Lifecycles Adaptations Inputs and outputs Subsystems Systems Questions

21 State Standards:

23 Todays Investigation Focus: Temperature

24 Familiar measurement. Can do on the school campus. Creates a common reference point. We want to limit our investigation to one measurement/environmental factor. Temperature Investigation

25 Our essential question for this investigation is: Temperature Investigation Temperature Investigation

26 Our essential question for this investigation is: How does temperature vary in different microclimates? Temperature Investigation Temperature Investigation

27 Comparative Investigation Question Which location on our school campus: in the grass, under the bushes, or on the sidewalk has the highest surface temperature °__(C or F)?

28 What is the manipulated (independent, changed) variable? What is the manipulated (independent, changed) variable? What will we measure? (measured, responding, dependent variable) What will we measure? (measured, responding, dependent variable) Temperature Investigation

29 What is the manipulated (independent, changed) variable? Underline the manipulated variable in the question. What is the manipulated (independent, changed) variable? Underline the manipulated variable in the question. What will we measure? (measured, responding, dependent variable) What will we measure? (measured, responding, dependent variable) Temperature Investigation

30 What is the manipulated (independent, changed) variable? Underline the manipulated variable in the question. What is the manipulated (independent, changed) variable? Underline the manipulated variable in the question. What will we measure? (measured, responding, dependent variable) What will we measure? (measured, responding, dependent variable) Double underline what we will measure in the question. Temperature Investigation

31 What should we keep the same (controlled variables) in this investigation? How should we make sure our samples are random and representative of the area? (validity measures) Random Sampling Example in the Field Investigation Guide, pg. 26 Constant Variables

32 Write an hypothesis with reason Address one condition of the manipulated (changed) variable. What do you predict you will observe or measure with this condition? Give a reason. HypothesisPrediction

33 Thermometers Thermometers Stopwatch Stopwatch Rulers Rulers Paper Paper 3 locations: on top of the grass, under a bush or on the sidewalk. 3 locations: on top of the grass, under a bush or on the sidewalk. List Materials

35 Data table: Clear title that describes what is to observed/measured Clear title that describes what is to observed/measured Manipulated (changed) variable: on the left side Manipulated (changed) variable: on the left side Measured variable: Space for observations/measurements clearly labeled and with proper units when applicable across the top Measured variable: Space for observations/measurements clearly labeled and with proper units when applicable across the top Multiple trials clearly labeled and space for averages or calculations if applicable across the top Multiple trials clearly labeled and space for averages or calculations if applicable across the top Temperature Investigation

36 Teams of 2 (or 3). Each team will go to all 3 locations. At each location take 3 temperature measurements (repeated trials). Remember to write a description of the study site and record date, time, and place! Temperature Investigation

38 Calculate your averages. Write each average on a different sticky note (fill up the space). Yellow = Grass Pink = Bushes Blue = Sidewalk Place your sticky notes on the number line: yellow above, pink on the line, blue below. Temperature Investigation

39 What was the highest temperature anyone recorded? What was the lowest temperature? Initially does it appear your prediction was correct? Anything you would want to do differently next time? Temperature Investigation

40 Write up the procedure for our investigation. (what we just did) Look at your Field Investigation Format flap, as needed. And…

41 Remember when writing your investigation to include: The manipulated (independent or changed) variable The manipulated (independent or changed) variable The responding (dependent or measured) variable The responding (dependent or measured) variable The controlled variables The controlled variables Temperature Investigation Temperature Investigation

56 Conclusion At Dearborn Park Elementary on March 18, 2005 on the black top had the highest surface temperature. On the black top had the highest average surface temperature of 17 °C. On the open grass had the lowest average surface temperature of 10 °C. Our prediction that the black top would have the highest temperature was correct. Page 32

57 Discuss factors that may have influenced data. Discuss improvements to the procedure to control some of those factors. Explain any inconsistent data. Explain how this information might be important in the real world. Explain how this information should inform actions or decisions. Cite further questions for investigation. Discussion

58 How does the temperature investigation help me understand the ecosystem? What are other abiotic factors we could measure on this site? Microclimates Discussion

59 Choose one descriptive and comparative investigation to do with classroom: 1) 1)Determine and write down a descriptive question. 2) 2)Determine and write down a comparative question. 3) 3)Create a data table for a question you will investigate with your classroom. Planning a New Investigation
