Lab-Aids: Investigating Light Module (no Light Stations) Kit
Shadows are almost always present, but most of us haven„¢t ever stopped to interpret them as evidence of light„¢s varied interactions with matter. The six activities in this module allow students to explore the behavior of shadows, light„¢s interactions with matter, and the straight line nature of light. Working with light beams, students quantify the size of a shadow and use shadows to mathematically determine the sizes of objects. The activities in this module (and in the related LAB-P120 and LAB-P130 modules) were developed at the University of Kentucky and include materials designed for seamless use with LAB-AIDS‚® Light Stations. LIGHT STATIONS NOT INCLUDED.
Investigations:
Exploring the behavior of shadows and the straight line nature of light
Characterizing shadows and the effect of different light sources
Working with light beams, and examining light„¢s interactions with matter
Quantifying the size of a shadow
& 6. Two investigations that apply shadows to graphically and mathematically determine unknown sizes of objects
Scientific Concepts:
Light travels in a straight line.
Light interacts with objects in a predictable fashion with predictable results.
