Geometry Project Mrs. Montoya MGS22

How Tall is it?

Directions:

1.  Make your clinometer.

2.  Designate the object you are going to measure. Object must be at least 20 ft tall.

HINT: Choose an object with a flat area around it and not too tall (nothing above a 3 –story building).

3.  Work together with your partner to determine the height of the object using trigonometry.

4.  Prepare a PowerPoint presentation (see expectations below) with conclusions.

Resources:

ü  clinometer

ü  digital camera

ü  assume that the average step is 2 feet

Requirements:

à  Measure and calculate the height of the object with 4 different triangles

·  30⁰

·  45⁰

·  60⁰

·  angle measure of your group’s choice

à  Pictures of each which includes one group member with the clinometer, the object, and the ENTIRE triangle.

à  Diagrams illustrating the picture with measurements and calculations included.

à  PowerPoint Slide Show w/ 6 slides:

·  Slide 1 - Title Slide with group members names, class, date

·  Slides 2 – 5 Include picture and diagram of each case.

·  Slide 6 – Conclusion Slide with average height calculated and description of the process and/or “lessons learned”

à  PowerPoint show should include animation, slide transitions and at least 3 pieces of clipart.

à  Print the handouts version w/ 6 slides on a page of your PowerPoint Show

à  Email your presentation to Mrs. Montoya at

The purpose of this clinometer is to measure the incline of what your are looking at. This step by step instructable will show you how to make a DIY(Do it by yourself) version a clinometer that works pretty well.


Items needed are:
*1 Straw that is large enough to see down the hole
*1 Protractor
*1 foot piece of string
*A weight that is heavy enough to keep your string stiff
*Scissors & Tape

Steps:

1. Tie one end of the string to the weight.

2. Tie the other end of the string to the center hole in the base of the protractor. Make

sure the knot lines up with the center hole and not the outside or inside of the protractor.

3. Tape the drinking straw to the flat edge of the protractor. Make sure the ends of the

straw lie flush with the corners of the protractor.

4. Turn the protractor upside down. The weight should pull down the string so that it

passes through the degree measures when the clinometer is turned.
