This lesson's primary focus is to introduce high school students to the concept of Elasticity, which is one of the fundamental concepts in the understanding of the physics of deformation in solids. The main learning objectives are: (1) To understand the essential concept of Elasticity and be able to distinguish simple solids objects based on degree and extent of their elastic properties; (2) To appreciate the utility of the elastic force vs. deformation curve through experiments; (3) To be aware of potential sources of error present in such experiments and identify corrective measures; and (4) To appreciate the relevance of Elasticity in practical applications.
