Oer Curve Fitting Applied To Easter Island Stone Foundations, Cynthia Huffman Ph.D.
Oer Curve Fitting Applied To Easter Island Stone Foundations, Cynthia Huffman Ph.D.
Faculty Submissions
In this activity, curve fitting is applied to drone pictures of ruins of stone foundations of the traditional houses (hare paenga) on the island of Rapa Nui. The free mathematics application GeoGebra (geogebra.org) is used, but the activity can be adapted to other technology, such as Desmos (desmos.com). The activity can be used as a teacher demonstration or completed by students, individually or in small groups, with access to computers.
Oer Ellipses And Traditional Rapanui Houses On Easter Island, Cynthia Huffman Ph.D.
Oer Ellipses And Traditional Rapanui Houses On Easter Island, Cynthia Huffman Ph.D.
Faculty Submissions
This worksheet activity is appropriate for secondary students in a class studying conic sections or students in a college algebra class. The first part of the activity gives an algebraic review of ellipses with exercises while the second part finds the equation of an ellipse corresponding to a Rapanui boat house foundation.
Oer Indoor Ellipse Multicultural (Easter Island) Activity, Cynthia Huffman Ph.D.
Oer Indoor Ellipse Multicultural (Easter Island) Activity, Cynthia Huffman Ph.D.
Faculty Submissions
This activity would fit in with a secondary or college algebra class studying conic sections, in particular ellipses, and gives students a multicultural hands-on application of the definition of an ellipse, while tracing out a scale model of the foundation of a hare paenga (boat house) from prehistoric Easter Island (Rapa Nui)..
Oer Outdoor Ellipse Multicultural (Easter Island) Activity, Cynthia Huffman Ph.D.
Oer Outdoor Ellipse Multicultural (Easter Island) Activity, Cynthia Huffman Ph.D.
Faculty Submissions
This activity would fit in with a secondary or college algebra class studying conic sections, in particular ellipses, and gives students a multicultural hands-on application of the definition of an ellipse, while tracing out a full-scale model of the foundation of a hare paenga (boat house) from prehistoric Easter Island (Rapa Nui)..
