Looking More Carefully at Parallel Lines
Can you prove it? Making assumptions in geometry is commonplace. This resource requires mathematicians to prove the parallel line postulate through constructions. Learners construct parallel lines with a 180-degree rotation and then...

Light My Fire!
Students draw a diagram that shows the law of reflection. For this physics lesson, students investigate the relationship between the angle of incidence and angle of reflection. They explain how light travels as it reflects on a surface.

Reflection of Light With Two Plane Mirrors- Double Mirrors Placed at a Number of Angles
Students place two plane mirrors at different angles to experiment with reflection. They make kaleidoscopes and periscopes.
Curated OER
Angles and Arcs
Students discuss the sum of central angles and use string to create them on circles. They find the measure and length of both minor and major arcs.
Students give examples of concentric, similar, and congruent circles and congruent arcs.

Try Angle
Does practice make perfect or just improvement? Scholars practice drawing a triangle on an Etch-A-Sketch. They learn about the part of the brain that controls sensory-motor integration and apply that to an analysis question.

How We See Things
Students study light. For this lesson on light, students discuss how flat and angled mirrors reflect light and draw a picture showing how a mirror reflects light into an eye.
Curated OER
Reflection
Eighth graders use a stencil to make a figure with which they discover the horizontal line of reflection, the vertical line of reflection, and the diagaonal line of reflection using coordinates.

Reflecting and Observing on the Field Trip to the Pond
Students create an informative caption for photographs taken on a field trip to a pond. For this pond ecosystem lesson, students take photographs and create captions for them. Students write a reflective essay on a picture they feel...
Curated OER
Laws of Reflection
Students experiment with mirrors to explore the Laws of Reflection. In this experimental lesson students develop their own experiments and follow a list of assigned steps then report what happens in their activity.
