Forces Acting on a Spring

Teaching elastic forces in your physics class is a snap with this resource! Scholars compare the stretch of rubber bands with differing width, then measure the stretch of a spring and calculate force. In a whole-class experiment, wire is attached to the ceiling and stretched by adding weights to the loose end. When the weights are removed, does the wire return to its original length? Materials lists, procedures, background information and assessments are all provided for your convenience.
