Day 1 - we played with primary colors and ghost colors. When you look at the red circle for 30 sec or so and then look at a white piece of paper, you see a light blue circle appear (for the yellow, you see a light purple one and for the blue, a light orange/yellow one). Quite fascinating!
Day 2 - We talked more about complementary colors more in depth.
Day 4 - We experimented with the classical dispersion of light by a prism. Always beautiful to watch!
We changed our daily schedule quite a bit. I will post about this soon.
