Fermiproblems - Use fermiproblems to encourage students to be comfortable making estimates and discovering ways to estimate with only limited data available. Worked examples are available here

  • A list of Problems is available here

Skill-set

  • Using available sources to find information
  • Quickly vetting sources
  • Acquiring a feel for how to determine what factors are significant
  • Learning how to make estimates where figures are not available
  • Learning how to show and defend the reasoning behind extrapolations
  • Being able to make quick back of the napkin calculations
  • Understanding of what significant figures are and how to calculate them
  • Understanding the difference between accuracy and precision

Materials needed

  • Problems which are relevant to the models which the students will later be constructing in the class
  • Worked through examples showing a complete model and demonstrating which information is necessary for a ballpark estimation and which is not.
  • Problem sets for the students to work through
  • A quick example of scale such as powers of 10

Comments

Pros

  • What makes a good model vs. what makes just a model

Cons

Comments

  • Is this included in all of the other units, or also use this and then use these skills in lots of other places?
    • We need to make sure that this - if it's a unit on its own - that it isn't a very boring first unit
  • Include talking about orders of magnitude, scale, significant figures, accuracy vs. precision, pattern recognition

To Do

  • Sam has a high school teacher who has a list of many examples, he is going to get in contact with them.
  • Think about and perhaps talk to Fitz/Brad about how much from Fire could be used to address this foundation unit
