Light & Images. Ideas in Science. Notes for Teachers.
Murphy, Pat, Ed.
This teaching guide provides background information, instructions, and copies of sample cards needed for an image walk, a series of demonstrations and activities that reveal the images carried by sunlight. The three cards are used: (1) to demonstrate that sunlight passing through holes of any shape create round spots of light--images of the sun; (2) to reflect sunlight and make images of the sun, and to demonstrate that a large square hole acts like a collection of small holes; and (3) to study the array of images that result from an array of holes. The cards, originally printed on cardboard, include outlined areas indicating punchouts needed to accomplish the demonstration activities. Also provided are activities which extend the image walk, continuing the process of discovery using pinhole viewers and a slide projector. (JN)
