This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).

In this lab (Activity #1 on page), learners explore how we see color.

In this activity, learners test the Law of Reflection based on experimental evidence. Learners produce raw data and explanations based on their data: pencil tracings of incident and reflection rays.

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color.

This simple hands-on activity demonstrates why the sky appears blue on a sunny day and red during sunrise and sunset.
