For the above, students calculated the densities of various objects using valid measurements, made and analyzed graphs, and studied the relationships between different variables. They also did varied problems to apply what they had learned.
Students further investigated the relationship between mass, volume, and density through graphs. They calculated slopes and wrote linear equations.
