Calculating Volume in the Forest
Eighth graders use their knowledge of calculating the volume of cylinders to calculate the volume of trees. For this volume lesson plan, 8th graders identify why calculating the volume of cylinders would be valuable to a forester.

The Shadow Knows - Measuring A Telephone Pole
Third graders attempt to determine the height of a telephone pole or tree without climbing to the top.
Curated OER
The Shadow Knows - Measuring Other Students
Eighth graders measure height and shadow length of other students on a sunny day and develop a ratio. They apply the ratio to other students and objects using shadows to determine height.
Curated OER
Measuring Rainfall
In this activity, students will make a gauge to measure rainfall and see how much rain falls over several days.
Curated OER
Tree Study
Students measure the lengths of provided leafs to the nearest millimeter. Students identify trends in the data as well as sourced of inaccuracy and formulate additional questions that could be investigated to enhance their understanding.
Curated OER
Customary Units of Length
For this customary length worksheet, students solve 5 multiple choice problems where they must choose the better estimate of customary length. Students then answer 9 fill in the blank problems and 1 word problem, where they must convert...

Science: The Age of the Redwoods
Students discover how to estimate the age of redwood trees. They measure the trees' diameters by using string to calculate the circumferences. Students conclude by discussing the science of dendrochronolgy.
Curated OER
Measuring Rainfall
Students investigate the amount of rain that falls in their area through the construction and monitoring of a rain gauge. The gauge is observed for one week, recordings are made, and observations described in a chart.
Curated OER
LET'S INVENTORY THE SCHOOL FOREST
Young scholars study how to estimate the diameter of a tree, estimate the height of the tree using shadows, estimate the height of the tree using a ruler, and use tools for measuring trees.
Curated OER
Wanted Dead or Alive...How Big Is it?
Fourth graders estimate the measurements of trees using unconventional techniques.

Altitude Locator
Students use protractors, strings, and straws to construct a device used to determine the height of tall objects. In this applied geometry instructional activity, students use common objects to construct a tangent height guide. They use...
Curated OER
Tennis Triangle
Students calculate the height of a tree or flagpole. They measure the shadow of the tree or flagpole and the length of a shadow of a meterstick. Using similar triangles, calculate the heigh. Devise two additional ways in which to measure...

How High did My Rocket go?
Students shoot off a rocket and measure the trig ratios relation. For this geometry lesson, students practice using an inclinometer to figure out how high their rockets fly. They measure angles and height and relate it to gravity and...
Curated OER
Similar Triangles
Ninth graders find the height of every day objects using techniques learned through postulates that allow triangles in a problem to be similar. They calculate the length of a missing side and solve proportions.
