Physics 8A

Refraction summative — tick-list check, then hand in.

Refraction summative — evaluation and improvements (C3–C5).

Refraction summative — the planning sections (B1–B3), then C3.

Measuring refraction — the semicircular block on the protractor card.

Refraction I — why light bends. The marching-band model.

Finishing the law of reflection — completing the angle calculations and the write-up.

L3 — The law of reflection. Specular vs diffuse, then the practical: ray box, plane mirror, protractor — measure i and r and find they are equal, both measured from the normal.

L2 — The electromagnetic spectrum, overview. Seven regions ordered by energy, then nineteen everyday uses sorted into them.

Colour perception — the Beau Lotto activity, following on from the TED talk. Catch-up: this class had not really done the worksheet.
