Lost in the City with a Clinometer
Come look at trigonometry from a different angle. To begin a simple activity, scholars view a video of someone using a clinometer to find the angle of elevation to the top of a building. They then use a diagram that shows the building's...
Mathematics Vision Project
Similarity and Right Triangle Trigonometry
Starting with similar triangles and dilation factors, this unit quickly and thoroughly progresses into the world of right triangle features and trigonometric relationships. Presented in easy-to-attack modules with copious application...

Applying Tangents
What does geometry have to do with depression? It's an angle of course! Learners apply the tangent ratio to problem solving questions by finding missing lengths. Problems include angles of elevation and angles of depression. Pupils make...
Texas Instruments
The Leaning Tower of Pisa
Learners estimate the equation of a line, angle of elevation and depression in this math lesson. They analyze e famous landmark design and make connections to algebra and geometry. They will also generate an equation, model the x and y...
Radford University
Pirate Attack
Arr ye matey, it's time for some trig. Learners first read up on the 2010 attack on the USS Nicholas by a group of pirates and the testimony of one of the witnesses. They use right triangle trigonometry to determine if the account is...

Physics Lab Rockets
Students construct and test balloon rockets and a model rocket. In this rocket science lesson, students use an inquiry-based method to master balloon rockets and have a shoot-off with the goal of attaining the highest altitude. Next,...
GLOBE Program
Making a Sundial
Sundials are more than just primitive clocks. Learners build their own sundials to study the location of the sun across the sky throughout the day. They use shadow evidence related to their sundials to make conclusions about solar movement.

Atomic Absorption Determination of Zinc and Copper in a Multivitamin
Advanced lab apprentices prepare zinc and copper solutions to which they will compare the same minerals from a multivitamin. Using absorption spectroscopy, they analyze the contents of the multivitamin for concentration. This lab can be...
Bowels Physics
Newton's Second Law
Were it not for Sir Newton, our understanding of physics and matters of the world would be drastically different. Present your class with detailed information of Newton's Second Law as they explore the concepts of mass and acceleration....
Curated OER
Navigation By the North Star: A Lesson Plan in Four Parts
Students investigate why the North Star was important for navigation, how stars move across the night sky, how to locate the North Star, how to make a crude sextant, and how to determine latitude using a sextant and the North Star. They...
Curated OER
Measure Up!
Students examine parallax and angular measurements. In this investigative instructional activity students calculate distances of objects and map their results.
Curated OER
Right Triangles and Unit Circles
Students evaluate the six trigonometric values of a trig function. In this trigonometry lesson, students use the Unit Circle to find the values of right triangles and their angles. They identify an angle of elevation and...
Curated OER
Catapults!
Students work together to discover the relationship between the angle of catapults and the flight of different objects. They discover the heavier the object the more force is needed. They examine how engineers use this information to...
Curated OER
Solving Right Triangles
Students investigate the basic trigonometric functions. In this geometry/trigonometry lesson, students explore strategies to solve right triangles using basic trigonometric functions. The lesson includes an application...
Curated OER
Geometry of Exploration: Eyes Over Mars
Students research how engineers and scientists generate linear and angular measurements with geometry to survey the Earth and Mars. They assess how geometric shapes affect navigation. A surveyor comes to the classroom and explains how he...
Curated OER
Wind Tunnels
Students build a simple wind tunnel and test out 2 glider wing shapes at different angles of attack. They record their observations and results just as engineers do. There also is a "virtual wind tunnel" they can try to test aerodynamic...
Curated OER
Slope and Tangent
Students differentiate between the slope and the tangent of the horizontal. In this precalculus lesson, students examine slopes created by tangent lines. They observe the angle formed using properties of the unit circle.
Curated OER
Eratosthenes
Students examine what Eratosthenes is and the history behind him. In this earth lesson students complete a hands on activity to repeat Eratosthenes' experiment.
Curated OER
Wave Equations
Pupils manipulate a model of a wave in order to solve the wave equation in 1 dimension. By using a model of a wave on a string the student is able to change the tension, length, and mass of the string as well as fix either end of the...
