Curated OER
Please Turn Up the Lights!
Eighth graders discuss series and parallel circuits and design an investigation to test a hypothesis on total resistance of series and parallel circuits in combination. After discussion, groups design their experiments, run tests, and...
Curated OER
Radius, Diameter and Area
Pupils identify the radius and diameter of a circle. In this geometry lesson, students calculate the volume and area of a cylinder and circle. They relate the circumference of a circle to Pi.
Curated OER
Unit Circle and Triangle
Students apply the Unit Circle to solve ratios of triangles. For this geometry lesson, students derive the different ratios of a triangle using the Pythagorean Theorem. They find the angles of a unit circle using a right triangle.
