Curated OER
Clinometer
Seventh graders build their own Clinometer and using the tangent of angles, estimate the height of trees. Then these students develop and activity to show whole class and determine the tallest tree on school property.
Curated OER
Shadow Casting
Eighth graders use a meter stick that is placed on a horizontal surface and an object is moved along it so that the shadow length can be measured at different distances from the light source. They solve real-world problems involving...
Curated OER
Hands-On Geometry
Tenth graders construct a variety of geometric shapes and designs using a Mira, Clinometer and Geometry Flash Cards. They complete a worksheet.
Curated OER
How High Is That?
Students explore the National Spatial Reference System. In this vertical position lesson, students will discuss the use of vertical position data and solve practical problems involving geographic positioning.
Curated OER
Toothpicks and Timber
Young scholars problem-solve how to log five acres. Working in pairs, they construct models of logging sites before and after the trees are harvested. they paint their models and include other environmental details.
Polar Trec
Playground Profiling—Topographic Profile Mapping
The Kuril islands stretch from Japan to Russia, and the ongoing dispute about their jurisdiction prevents many scientific research studies. Scholars learn to create a topographic profile of a specific area around their schools. Then they...
Curated OER
ndirect Measurement Technique: Using Trigonometric Ratios
Ninth graders find the height of an object that would be difficult or impossible to measure directly. They construct and use a Clinometer to measure the angle of elevation (or depression). Students create a sketch of the measurement...
Curated OER
The Tangent Ratio
Students calculate the tangent ratio given a right triangle. In this trigonometry lesson, students use a right triangle and the Pythagorean Theorem to solve problems.
Curated OER
Hot Air Balloon Design Lesson Plan
Sixth graders discuss what they know and what they want to know about hot air balloon using a KWL chart. They then use a wide array of materials to design a hot air balloon that will lift successfully in cooperative groups referring to...
Curated OER
Tree Identification
High schoolers list four ways to identify trees. In this tree identification instructional activity, students use tree identification techniques such as leafs, bark, wood grain, soil type, and climate to create tables and graphs.
Curated OER
Whatcha Gunna Do When the Hulkster's Measuring Too??
Students measure using tools they have made. For this algebra lesson, students measure the height and distance using non-traditional measuring methods. They apply their findings to algebra and trigonometry properties of measurements.
Curated OER
Basic Tree and Forest Measurements
Young scholars examine how trees are measured and the different methods used. For this density lesson students divide into groups and practice the different methods.
Curated OER
Landslides!
Young scholars discover soil and Earth movement by experimenting in class. In this Earth Science instructional activity, students utilize a stream table, soil, graduated cylinder and water to create a re-enactment of a landslide. Young...
Curated OER
Investigating the Soil
Students explore the Earth's crust by researching pH levels and acidity. In this environmental safety lesson, students identify the pros and cons of acidity within soil and how it affects plants. Students collaborate in a pH level...
Curated OER
Using Trigonometric Ratios
Students solve problems using sine and cosine. In this trigonometry lesson, students apply the properties of sine and cosine to solve triangular problems. They identify when to use law of sines using angle-side relationships.
Curated OER
Optional Laboratory: Measuring Tree Heights
Students work together to measure tree heights. They make predictions on what they believe the calculations are and answer questions during the experiment. They share their results with the class.
Curated OER
Trigonometric Applications Outside the Classroom
Fifth graders describe and demonstrate how trigonometry can be used to find the height of a tall building or tree. They describe and demonstrate how trigonometry can be used to find the height of a high hill, or other high object where...
Curated OER
Optional Laboratory: Calculating Board Footage in a Tree
Students work together to complete an experiment calculating the amount of board footage in a tree. They record their data and answer questions at the end of the lesson. They create their own hypothesis as well.
Curated OER
How Fast Does This Tree Grow?
Young scholars work together to determine how fast trees go. They make predictions and complete simple measurements. They answer questions to end the lesson.
