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
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 * Include talking about orders of magnitude, scale, significant figures, accuracy vs. precision, pattern recognition
