How tall is the light pole?
1 Project Instructions
Students will recieve 1 piece of string between 10 and 20 feet long, one straw, and a piece of duct tape. They will be directed to tape the straw onto the top of their iPad while holding it vertically.
Using the string students will stand that determined distance away from an object they are chosing to measure.
Students will open up the app Clinometer on their iPad. Looking through the straw similar to a sight on a gun, the students will line up objects in their sight that are taller or shorter then they are.
While they have the object in their sight, another student will read the angle of elevation or depression (depending on whether or not the object is higher or lower than their plane of sight) from the Clinometer app.
The second student in the group of two should take a picture of the student looking up or down at the object through their iPad scope. They will use this picture to draw over and show their work on for turning in their assignment.
Using the given distance the students are standing away from the object and the angle of elevation or depression students work to figure out how tall the object is using what they have learned about trigonometry. Have students figure out how to add or subtract additional height as the iPad is not at the ground level.
Assign the students 5 objects around the school to find the height of. In the end, the students should have 5 images that are marked up in another app such as notability or skitch and the work should be shown as to how they have calculated the objects height.
