aleonthey- :1- ‐2classperiodsStandard(s):CST standard: INVESTIGATION AND EXPERIMENTATION9. Scientific progress is made by asking meaningful questions and conducting careful investigations. Asa basis for understanding this concept and addressing the content in the other three strands, studentsshould develop their own questions and perform investigations. Students will:a. Plan and conduct a scientific investigation to test a hypothesis.c. Distinguish between variable and controlled parameters in a test.e. Construct appropriate graphs from data and develop quantitative statements about therelationships between variables.NGSS:Science and Engineering PracticesPractice 3 Planning and Carrying Out Investigations Grade 6-8: Plan an investigation individually and collaboratively, and in the design: identify independentand dependent variables and controls, what tools are needed to do the gathering, how measurements will berecorded, and how many data are needed to support a claim.Practice 4 Analyzing and Interpreting Data Grade 6-8: Construct, analyze, and/or interpret graphical displays of data and/or large data sets to identifylinear and nonlinear relationships.InstructionalResources/Materials: Handoutsprovidedbelow.- ‐WarmUpProbe- ‐Assessment:ConstructingaGraphfromData- ‐Assessment:ModifyingDesignforFlight aphpaperprovidedbelow) Blankpaper(ortemplate)forcreatingairplanes ssors,paperclips,etc.Page 1 of 13WCCUSD 11/07/14

Modifying Design for FlightPart IUse the template to fold a paper airplane with regular printer paper. Throw the airplane five times,measuring the distance in centimeters. Finally, find the average distance this plane flies.Part IIDecide with your partner what single change you willmake to your airplane. Will you use a differentFlight distance of Flight distance ofTrial #original planemodified planematerial to make the plane? A different size or shapeof paper? Modify the way it is folded? Add weight to1partoftheplane?Somethingelse?2What change did you make to the plane?345averageAs in Part I, measure the flight of your modified planefive times, and find the average.Part IIINow, using your data from the table above, construct a bar graph that shows your results. Label the x-axis with your manipulated variable, and the y-axis with the responding variable. Make note of the range of your data above—How high do the numbers on your graph need to go? Determine the appropriate scale to use—How many centimeters will each square on your graphrepresent? 1 cm? 2 cm? 5 cm? more?Page 8 of 13WCCUSD 11/07/14
