### PRODUCT DESCRIPTION

Shadow Activity - Similar Triangles and Trigonometry (Geometry Outdoor Activity)
Common Core Aligned Activity or Lab Project

Activity Description:
This is a student led activity or project where students have an opportunity to apply similar triangles and trigonometry concepts in a real world situation. Students will be required to find the height of an object (indirectly) that would otherwise be very difficult to measure and then they will have to find the angle of elevation of the sun. The project also has an extended activity where students can check their work with an inclinometer.

This activity also includes guided questions and questions for discussion before and after the project.

Activity Objectives:
Part 1 - Find the height of an object that would otherwise be very difficult to measure.
Part 2 - Find the angle of elevation of the sun.

Common Core State Standards:
N.Q.2 – Define appropriate quantities for the purpose of descriptive modeling.
N.Q.3 – Choose a level of accuracy appropriate to limitations on measurement when reporting quantities.
G.SRT.5 – Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric figures.
G.SRT.8 – Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.
G.MG.1 – Use geometric shapes, their measures, and their properties to describe objects.
G.MG.3 – Apply geometric methods to solve design problems.

Mathematical Practices:
MP1. Make sense of problems and persevere in solving them.
MP3. Construct viable arguments and critique the reasoning of others.
MP4. Model with mathematics.
MP5. Use appropriate tools strategically.
MP6. Attend to precision.
