High schoolers determine the linear equations of the density of water and oil by collecting data on the mass of various volumes of each liquid. They construct scatter plots from the data and use these to write the linear equations for...

Pupils explore the physical properties of density. In this hands-on lesson, students calculate density and distinguish between intensive and extensive properties.

Fifth graders record measurements and calculate the volume. They select and use appropriate units and procedures to measure volume # use tools such as technology to solve problems
