An important aspect of science education involves helping students learn to read and communicate scientific information and arguments. In this note, I would like to share a resource that I have come across which I have found to be a useful tool for helping students improve those skills, learn content material, and acquaint them with a great…

A simple low cost demonstration experiment is performed using common apparatus in order to show various flexural patterns and to give a dynamical measure of Young's modulus. (Contains 4 figures.)

This paper tries to demonstrate that it is not reasonable to judge the quality of pictures that a camera can produce just by the number of pixels that the sensor has. It does so by trying to relate the number of pixels in a picture to the resolution that the eye can see at various distances away from prints of different size.

Uses a diode array spectrometer to explain why blue objects appear red when viewed through the yellowish amber lens of "blue blocking" sunglasses. (JRH)

The effect of background color on the perception of color by students is discussed. Explanations on why students only see certain colors when viewing colored marks on a blackboard through different color filters are provided. (KR)

Describes an in-depth, comprehensive method that enables students to understand the basic concepts of visual perception. (JRH)

Uses a projector, a prism, and two screens to demonstrate the composition of white light and detect color. (MDH)
