We use mass and volume and plot them on a graph making 3 lines. We discuss why something might sink or float due to its density. We graph 3 objects, Water with a density of 1, a pencil with a density of 0.5 and a rock with a density of 2. This could be given to honors Algebra or Earth Science students or be used as guided practice with regular education students. It makes density more real life than just using numbers. It includes using the literal equation D=M/V and also the slope formula. I created this to show relationships between math and science and why each one is important for the other.
