    Project Description

    Name of ProjectVolume: Cross Sections
    Subject AreaAP Calculus AB
    Targeted StandardsEU 3.4 The definite integral of a function over an interval is a mathematical tool with many interpretations and applications involving accumulation.  LO 3.4D Apply definite integrals to problems involving area, volume.
    Driving Question / Problem / ActivatorHow do we find volume using Known Cross Sections with a variety of bases?
    Project SummaryCreate a 3 dimensional model using known base shapes such as square or rectangle, circle or semi-circle
    Estimated Time60-90 minutes

    Project Outline 

    AskHow can a seemingly 2 D shape have volume
    ImagineUsing perspective:  imagine the underside of the surface of a lake with depth related to the dimensions of the 2 D visible shape
    PlanShow students a seemingly 2 D figure; apply area between 2 curves to model the figure’s depth
    CreateStudents will first create an area between 2 curves and choose/select a cross section.  They will model their 3 D shape using graph paper and create a tangible model using the 3 D printer
