This multimedia Learn Alberta math resource looks at how parabolas and polynomial equations are used to study an object's flight path. The accompanying interactive component lets students explore and make comparisons of the flight paths...

This reference material introduces the terms and equations related to parabolas in the context of conics. Also, relates concepts to previously-learned material and shows how to 'read' from the 'conics' form of the parabola equation.

This is a TI-Navigator Activity Center file that is used as a class warm up or for checking understanding. Students are to contribute an equation of a parabola that will pass through the most number of sunflowers.

A student, in writing to Dr. Math, wants to know how to find the equation of the parabola of McDonald's arches. Dr. Math helps the student get started with the problem.

Dr. Math, in a reply to a student question, shows how a parabola is just a quadratic equation.

A lesson plan using the computers to help students understand the various forms of equations of parabola. The site requires students to use the computer and offers a possible assessment of the lesson.

Students learn to graph the equation of a quadratic function using the coordinates of the vertex of a parabola and its x-intercepts.

Posed with a student question about equations of conics, Dr. Math provides some insight on the standard form of parabolas, ellipses, and hyperbolas. One example is shown.
