This paper focuses on the exploration of the reflection from a parabolic mirror and involves activities designed for students enrolled in at least Calculus I. Part III deals with solving differential equations and is suitable for some Calculus II students (where basic differential equations topics are covered) or for students taking Differential Equations course. Part I is suitable as a classroom activity, while part II is more appropriate as a homework assignment or project. Part III might be used as an introduction to Lagrange and Clairaut type differential equations ( if they are covered in the course). TI92 Plus scripts are provided for all activities. TI92 Plus scripts for solving Lagrange and Clairaut types of differential equations are given in the Appendix.
