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 lesson 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
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
Build a Sun Clinometer
In this sun clinometer learning exercise, students build a sun clinometer using a protractor, thread, straw, cardboard and a paper clip. They are graded using a rubric on their clinometer and they answer questions about the structure of...
Curated OER
Azimuth and Altitude Quiz 1
In this azimuth and altitude worksheet, students answer questions about celestial bodies and how they are measured. They label drawings of clinometers, celestial spheres, and a compass.
Curated OER
Blakesley Hall Maths Activities
In this math learning exercise, students record measurements of the Tudor House that they will visit. The learning exercise includes drawings of the Tudor House, and students write their actual measurements on the drawing. They find the...
Curated OER
Using the Clinometer
In this clinometer learning exercise, learners measure the altitude of ten objects using a clinometer. They answer questions about calibrating a clinometer and measuring with a clinometer.
Curated OER
Improve Your Clinometer
For this clinometer worksheet, students answer questions about a clinometer and what it is used for. They also list ways to improve their clinometers.
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
Toothpicks and Timber
Students 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.
TeachEngineering
Teach Engineering: Trigonometry via Mobile Device
Students investigate the relationships between angles and side lengths in right triangles with the help of materials found in the classroom and a mobile device.
TeachEngineering
Teach Engineering: Handheld Trigonometry
In addition to understanding the concept of similar right triangles and how they apply to trigonometric ratios, students explore a clinometer app, and discover how it can be used to test the mathematics underpinning trigonometry.
Exploratorium
Exploratorium: Ilion High: Build a Clinometer
Instructions for building a clinometer are given on this page. Clinometers can be used to measure the angle of elevation of a right triangle, and in turn find the height of large objects.
