Thar She Blows!: Wind Power
Students examine how wind energy is transformed into electrical energy. In pairs, they build miniature wind turbines and measure how much electrical current they produce. They asses the importance of design and position in energy...
Curated OER
Triangle Inequality Theorem
High schoolers investigate the relationship between angle measures and sides of a triangle and the relationships among the three sides of a triangle. The use of technology (Cabri, Jr.) allows learners to make and test conjectures as they...
Curated OER
Woody Sine
Students explore the concept of sine. In this sine lesson, students create a sine graph from tooth picks. Students create a unit circle with tooth pick length radius. Students then take the tooth picks from the unit circle and put them...
Curated OER
Leaping!
Students properly leap and measure their distance. In this leaping lesson plan, students practice leaping for accuracy and proper form. Students estimate their leaps and measure with rulers. Students determine distance covered by the...
Curated OER
King Henry Did What?
Young scholars convert between the different metric units after reading the Fairy Tale of King Henry. They measure various candies in a baggy using the width of their index finger. They record results to the nearest index finger width on...
Curated OER
Electric Hoist Problem
Students convert angle measures between degrees and radians. They are given a copy of the task sheet with a graphic to help describe the situation. Pupils review the angle and arc relationship in a circle related to length of the...
Curated OER
Let's Do the Wave!
Students distinguish waves from matter, differentiate between transverse and longitudinal waves, use sine curves as representations of transverse waves, label characteristic properties of waves, diagram transverse waves having specific...
Curated OER
To Float or Not to Float, That is the Question?
Ninth graders develop operational definition of density, do computations using density equation, categorize pieces of matter as being able to float on
water or not, based on density, explain why some objects sink or float based on...
Curated OER
SI Prefixes and Mass
In this SI prefixes and mass learning exercise, students are given measurements of mass and they covert to the given measurement by moving the decimal the proper number of places to the left or right.
Curated OER
Pre History through Modern Day Timeline
Students explore the historical sequence of cultures throughout history. They demonstrate the ability to organize events in chronological order and demonstrate how time is measured and annotated.

Sonar Mapping of the Ocean Floor
Eighth graders participate in an experiment that emulates a sonar signal bouncing off the ocean floor. They determine how the ocean floor is measured by the length of time it takes for the sonar signal to return. They work with a wooden...
Curated OER
Perpendicular Segments in a Circle
High schoolers explore the concept of circles as they construct a circle using a program such as Cabri Jr. Learners construct a chord and a diameter that are perpendicular, then measure the bisected chord and notice that both sides of...

Whites, Blacks and the Blues
This lesson enables students to explore and measure the distance between blacks and whites in the past and present United States. By thinking about the intersections of whites, blacks, and others around the blues, students will deepen...
Curated OER
Which Quadrilateral Is It?
Young scholars prove conjectures about geometric figures on the plane or in space using coordinate geometry. They develop fluency in operations with real numbers, vectors and matrices using mental computation or paper-and-pencil...
Curated OER
Acceleration, Drag, Gravity, Motion, Forces, and Friction
Eighth graders build and run mousetrap cars in order to measure distance, time, and mass for their cars. They use these measurements to calculate average speed and kinetic energy, then create a slide show to visually explain how the car...
