Rollin' your Science Practices


We will look at SEP 7 - Argumentation with the Exploratorium's  Slow your Roll activity (including how to build your own setup)
(we are off schedule for the SEPs - #7 is out of order)

  1. Sign In (verification of attendance for our grant)
  2. Quickwrite
  3. Engage - classroom video
    1. What is wrong with this discussion?
    2. What should our discussion look like?
    3. SEP 7
      1. Definition and progression
      2. Bozeman on SEP 7
      3. Kracjik on SEP 7

  4. Explore - Measure rolling, graph data, make arguments from evidence
    1. Make rolling happen - see below for details on making the rails
    2. Measure distance, speed, acceleration
    3. Prediction - how do different sliding/rolling differ?
      1. frictionless (air track)
      2. ball rolling
      3. Socrative
    4. Testing
    5. Developing Evidence based arguments
      1. Argument Template
  5. Explain - how can we do argumentation in class without taking too much time?
    1. FEPA - making argumentation easy
    2. Resource on sentence starters (and other helpful SEP resources) download the resource for SEP 6 & SEP 7 to see examples of sentence starters
    3. Example of chemical bonding packet using a final claim evidence reasoning
    4. Current technology
      1. Google Doc template
      2. Socrative
      3. Google Forms (four stages)
        1. Ask for explanation
        2. Voting
        3. Argument
        4. Consensus
    5. Future technology - Matador Moderator
  6. Extend -
    1. Why do argumentation?
    2. Building Rolling Ramps
  7. Evaluate - testing in the classroom

How to build the rolling rails

You need:

  • 2 EMT pipes 5 feet long (Orchard had 10ft polls that they cut for me)
  • 2 2-Gang metal junction boxes
  • 4 EMT connectors
  • 1 wooden or plastic disc 4-5 in in diameter - need to put a hole in the exact center
    • ideally with spots for weights
  • 1 wooden dowel 3/8 in (1cm) diameter about 4 inches long
