Exploring Diffraction - Science is Everywhere

What exactly is Diffraction?
Diffraction, coined by Francesco Maria Grimaldi in the 17th century, the term refers to the bending of waves around obstacles and openings. The term diffraction comes from the Latin diffringere, which means ‘to break into pieces’, and quite fittingly describes light breaking into different directions. Diffraction is quite different from a related term, refraction, which describes a change in direction, wavelength and speed of waves as they travel from one medium to another.

Phenomena-based teaching grounds scientific concepts in a context most students can relate to.
• Provide the vital understanding of ‘why’ a phenomenon occurs and make comprehensive engagement a priority for your lessons.
• Encourage autonomous learning by sparking questions, provoking discovery, and guiding investigations that will prepare them for future STEM education.
• Use cross-cutting concepts that all students have a reference for, simultaneously addressing equity across learning styles and abilities.
