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

Introduction
58 minutes
MiniGolf cheater story
Instructor will solicit input from students on what why the phenomenon
was observed or to offer explanation. 


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



Practice
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.



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