Delta, Delta, Delta
Source Institutions
In this experiment, learners construct an equilateral triangle using graph paper, a pencil, protractor and ruler. They also make a "laser triangle" using a laser pointer and front-silvered mirrors.
Polarized Light
Source Institutions
In this optics activity, learners experiment with polarizers (small dark rectangles) to examine light intensity.

Beam Me Up!
Source Institutions
This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

How Thick is Your Hair?
Source Institutions
In this activity on page 13 of the PDF, learners use a laser pointer (with known wavelength of light) to measure the thickness of a human hair.
