    Why Rockets Are Awesome, A Presentation, V2 Why Rockets Are Awesome, A Presentation, V2 Presentation Transcript

    • Why Rockets are Awesome ….and how they can be used to teach your students experimental design By Ringo Dingrando
    • This presentation, and all the presented material, is available on www.ringophysics.blogspot.com
    • Ringo Dingrando
      • High School Physics teacher at the International School of Manila
      • 7 years teaching physics, 3 years teaching IB Physics,
      • BS in Science Education – U of Missouri
      • MS in Educational Studies – State University of New York
    • Rocket Liftoff Clip
      • Rocket Liftoff Clip
    • Rocket Launcher demonstration A youtube clip of the rocket launcher in use. www.comingsoononyoutube.com
    • A Poor Rocket Assignment
      • First……….
      • Build a rocket! 
      • You are graded on this. 
      • Afterwards…
      • Discuss the physics of your rocket.
        • (boring)
      • Not graded
      • Emphasis is wrong!
    • A Better Rocket Assignment
      • First…
      • Build
      • Maybe Re-build
      • Ungraded 
      • Afterwards…
      • Design an Experiment
      • Collect data
      • Analyze data
    • Why Lab Design is Important
      • Independent and Dependent Variables?
      • Variables to Control?
      • Discuss please.
      • Why is it important for students to be able to do this?
    • The IB thinks Lab Design is Important
      • The IB
        • “experimental science courses should aim to develop experimental and investigative scientific skills” (p. 9 of the group 4 syllabus)
    • AP thinks it is important
    • Research on Importance of Lab Design
      • Link to research
    • How to Make a Great Design Lab
      • This will relate to the rocket launcher seen earlier
      • But the steps can be used for any type of design lab you like
    • 1. Get plenty of Equipment
      • Simpler is Better
      • Focus on lab design, NOT mastery of equipment
      • Should be interesting
      • Link: Plans For “Stomp” rocket launcher
      • Link: A more high tech launcher
    • 2. Make students familiar with equipment
      • This could be a half hour of trying to change different variables
      • My original assignment (LINK)
    • Pictures of Launch
    • 3. Brainstorm on variables
      • Different combos of independent and dependent
      • Few labs should be duplicates
    • Stick ‘Em Up Brainstorming -citation SUNY Masters Independent Variables Dependent Variables
    • 4. Show examples of good labs
      • Examples should involve different materials
    • Student lab
      • What are some other design lab ideas that could work well?
      • An example shown to students (LINK)
    • Other Lab Ideas?
    • 5. Write Design Lab
      • High School Design lab example on rockets (LINK)
      • Middle School Design lab example on heart rate (LINK)
    • 6. Provide Feedback
      • Pick your favorite format
      • IB Rubric is good
      • It can be modified for non-IB classes
    • The IB Lab Design Rubric
    • My Feedback Sheet G4IA Assessment sheet 11/3/2008 Student: Gonzales, Jose Investigation: Rocket Design Lab Time: 2Hrs Date(s): 08/01/08 Design General comments Ringo Dingrando This criteria is only addressed This grade will not appear on the PSOW 4 :) Excellent drawing. You do not state the increments of your independent variable measurements. You do not list the range of your measurements. It is quite clear how and where you intend to add the mass, but how much tape each time? What will be your maximum amount? What about multiple trials? Describing a method for collection of data 1 You do not effectively control variables. By adding extra tape to the tail every time, you WILL change the center of mass, but you are ALSO changing the very important variable of rocket mass. Controlling variables 1 You formulated a research question and identified the relevant variables. Great idea to change the center of gravity of the rocket! No one else thought of that! Great sketch graph to help visualize your hypothesis. Defining the problem and selecting variables 2 You are making similar mistakes as you did on previous labs. Please see the feedback on previous labs before you do your next one!

    • You could end here….
      • But if you have time……
    • 7. Do the best labs
      • Or all of them if possible
      • Or kids do other students’ labs
        • Promotes transparency in procedure writing
    • 8. Take the data stopwatch Data recording Cones for distance
    • More Data Taking
    • Continue on to the end
      • Analyze data with graphs
      • Write a conclusion and evaluation
    • Contextualizing Labs
      • As an added bonus
      • NASA research grant assignment (LINK)
      • Research on benefits of contextualization (LINK)
    • The End
