  1. Clinometers A MAKE AND TAKE BY LINDA TISDALE

  2. Where are we in the binder? • GLOBE Day 1 • Outline Letter “E” • Teacher’s Guide pp. 33-35

  3. What is a Clinometer? • A tool for measuring angles to determine heights of objects without directly measuring them. • An instrument that measures the steepness of slope.

  4. It is used by: • Highway construction engineers to measure angles of the land, • Movie production engineers to measure the height of the sun, • And by forestry engineers to measure the height of trees. Source: http://www.nativeaccess.com/ancestral/totems-intro.html

  5. “What Factors Affect Our Body of Water?” See page 30

  6. Materials for Each Person • Page 34 • One Metal Washer • 15 cm of Dental Floss • A LARGE Drinking Straw • One File Folder • One Plastic Sheet Protector • A Thumbtack to punch a hole

  7. Things to Remember at the Site • The person holding the clinometer should be at point “X.” • Person 2 will go about 50 m out away from “Person X.” • A third person is needed to read the clinometer. • Slope is labeled on the Hydrology Site Map (p. 38)

  8. You Can Measure A Tree Height • Look at the top of a tree through your straw. • Move back (still looking at the tree top) until your clinometer (the washer) is on 45 degrees. • Then measure your height (only your eyes to the ground). • And the distance from your feet to the tree base. • Lastly, add the measurements together: this is the height of the tree.

  9. Students will use longitude & latitude to locate positions. You can tie it in to math class: Graphing Plotting Points X-axis Y-axis Don’t forget about Alabama History: How could you make a similar game using points in Alabama? Play the game during the song! Message in a Bottle
