Algebra II Class Activity
Students in Mrs. Drinkwalter’s Advanced Algebra II class ran an experiment to test the elasticity of a rubber band. They used a paper cup and glass gems to put stress on the bands. They took measurements with a ruler. Their tools were primitive, but after taking 20 + measurements a mathematical trend did materialize. They used technology to calculate a regression line to model their results and then used computer software to print a graph as well.
