Inverse square law- BTEC Applied Science

This lesson is based on the inverse square law for Applied Science (Extended Certificate). It introduces the idea of attentuation which forms some of the basis for understanding the mathematics behind the equation for the inverse square law. It also includes main activities such as a demonstration in case practical equipment is not available to explore this concept, presenting results in a graph and calculations using the two equations required in for this lesson. Mark schemes for each activity as well as hints for calculations are also provided.
