Indirect Measurement Project

Project Description: Develop a plan to determine the height of the tree in Mrs. Wilson’s yard to determine if it falls the wrong way will the tree hit the house?

Supplies available:

100ft tape measure, 25 ft tape measure, clinometer, and a ruler.

Task:

  1. Write detailed, step-by-step instructions for Mr. Wilson to follow.
  2. Include diagrams to aid the explanation of the process.
  3. Write a summary of the geometric principles used.
  4. You will test your plan by determining the measurement of a tree in the AHS courtyard.
  5. You will then exchange plans with another group to see if they can replicate your results by following your instructions.
  6. You will be given an opportunity to revise your instructions before a third groups uses your plan.
  7. Turn in by the end of class on February 4, 2016:

Indirect Measurement Project

Task:Using the instruction given to you, find the height of the indicated tree. You must follow the plan as it is written. You must collect all data indicated and complete calculations as directed. Do NOT deviate from the plan. If the instructions are missing a step that you know is essential, you may write a note to the plan authors but must complete the instructions as given. If the instructions are vague or unclear, write a note to the plan authors to let them know the multiple ways you interpreted the instructions and which one you decided to use.
