1. Topic-
Mirrors & Reflections:
Interpreting Data
2. Content-
Mirrors reflect light forcing rays to travel differently than originally gathered. Using principles from the Law of Reflection, we can predict where the rays will be directed to through a few derived formulas. Using technology, the calculations can be setup for verification in a spreadsheet. This spreadsheet can then be used to represent the data with precision providing better concept development and clearly illustrates relationships between variables.
3. Goals: Aims/Outcomes-
1.Students will be able to use a spreadsheet application to check previous calculations.
2. Students will be able to use spreadsheets create a graph.
3 Student will be able to predict outcomes of reflective calculations utilizing created graphs.
4. Objectives-
1. Students will actively engage in dialogue and discussion that is consistent with comprehension.
2. Student will identify one question they have about the activity on a provided note card.
3.Students will cite an everyday use for relational graphs on the note card.
5. Materials and Aids-
Ipads, note cards, mirror packet,
6. Procedures/Methods-


5-8 minutes
Mini-Golf cheater story

Instructor will solicit input from students on what why the phenomenon was observed or to offer explanation.


10 minutes
Instructor will then introduce spreadsheet mirror calculator and students will select a problem from packet to check their work.


10 minutes
10 minutes
Class will physically graph on whitebaord single values /student/group for the object described in the table in reference to distance.

Independent Practice-

1.Students will create graphs that find Di v Do, Di v Di/Do,
Hi, m
(Do*Di) v (Do+DI), stating a generality for each data set (as one increases...the other....)

Checking for understanding-

1. Students will extrapolate 2 extra data values that are not on the table, and provide feedback as to what data to expect.
Student will then provide the solution to the problem on paper and check with calculator in spreadsheet.


1.Propose a solution (ball placement and hole location) for a mini-golf hole that our less than honest individual could use in his scheme:
