# How Thick Is a Soda Can II?

##### This How Thick Is a Soda Can II? activity & project also includes:

Science, technology, and math come together in this one combination exercise. Analyzing the common soda can from both a purely mathematical perspective and a scientific angle allows for a surprisingly sophisticated comparison of necessary assumptions along with sources and magnitude of error. An easily customized activity that could provide a quick warm-up or a multi-class experiment, depending on the information and directions given to the class.

CCSS: Designed

##### Instructional Ideas

• Divide the class into two groups and lead each group to a different solution method. Follow the activity with a comparison and discussion of error
• Use different beverage containers and the Archimedes' principle method to estimate the manufacturing material from density
##### Classroom Considerations

• Last page is blank, if copying costs are a concern
• Learners familiar with Archimedes' Principle will have a definite advantage in the second solution method, unless the whole class is brought up to speed together
##### Pros

• Careful treatment of assumptions and lengthy discussion of sources of error
• Multiple solution methods outlined
##### Cons

• The story of Archimedes and the King's Crown is briefly mentioned, but then treated as familiar without  a resource link
• Class assignment not separated from teaching notes and answer key
