ADA Accessibility: Inverse Trigonometric Functions
Ramp up using trigonometric ratios. After receiving a request to check school ramps to verify they meet ADA requirements, groups calculate the angle of the incline on ramps on campus. They report their findings via a letter to the...

Automobile-Accident Reconstruction
Learners investigate an accident and relate it to math. In this trigonometry lesson, students measure the accident scene, the friction produced, and the speed from the skid marks. They create a poster of their findings.
Curated OER
Roll It! Creating an Entrance Ramp
Students explore the concept of triangles. In this triangles lesson, students are to propose a plan for a ramp at their school. Students use the Pythagorean Theorem and trigonometry to determine the length, height, and angle...

When a Ruler is Too Short
Students measure distances using parallax. In this math lesson, students explain how this method helped astronomers with their studies of the solar system. They determine the length of their arm using parallax and compare it with other...

Meiosis
Using yarn and chenille stems, lab groups collaborate to model mitosis and meiosis. Brief background information and a vaguely written procedure comprise this outline. More instruction needs to be provided to learners about cell division...

Lab for Truss Design and Testing
Students design and build their own truss. In this physics lesson, students calculate the forces and maximum load. They complete a full scale diagram of their design.
