Product Description
This is an outdoor project with 5 stations for students to acquire hands on experience with indirect measuring using different tools, right triangle trig, and similar triangles.

Station 1: The mirror method
Students use a mirror to create similar triangles and measure the height of a tall object.

Station 2: The clinometer method
Students use a clinometer and tangent to solve for the height of a tall object. Directions to make a quick, simple, and cheap clinometer are included.

Station 3: The hypsometer method
Students use a hypsometer and similar triangles to solve for the height of a tall object. Directions to make a quick, simple, and cheap hypsometer are included.

Station 4: Shadow with Similar Triangles
Students use shadows and similar triangles to solve for the height of a tall object.

Station 5: Shadows with Trigonometry
Students use shadows and tangent to solve for the height of a tall object. Station 4 and 5 should actually be completed as one station.

Three reflection questions are included. A general answer key is included, but values will vary based on student data. I spend one day measuring and one day calculating during this project.

Required materials: clinometer (protractor, straw, string, weight), hypsometer (cardboard, straw, string, weight), mirror, multiple tape measures, tall objects, sunny day
