Next Generation Spacecraft—Orion

What is the cross-sectional area of the Orion spacecraft? Groups work together to estimate the area of a cross section of the Orion spacecraft by first counting the number of grids a scale drawing covers. Pupils also employ a method to decompose the scale drawing into figures they can use to calculate area.

Instructional Ideas

  • Have the class decompose figures to get an estimate of the areas
  • Review how to calculate percent error
Classroom Considerations

  • The calculations will be easier if pupils have access to calculators

  • The answer key provides one solution method to the problems
  • The activity has the groups check the percent error of their calculations based upon the actual area

  • Videos are difficult to find
