As a physical science teacher, one of my jobs is to teach my students how to measure like scientists. This includes, but of course is not limited to, distance with a ruler and mass with a balance. That is why I like to do a lab with the density blocks very early in the year. You use the rule to measure the length, width, and height of the blocks (in this case they're cubes, but hopefully sometime the Resource House will get some non-cube blocks) to calculate volume. They get practice using the triple beam balance finding mass. Finally they get to calculate density and put the blocks in order by density. A fun and engaging way to learn about the importance of measurement. Oh yeah, it's totally free too (thanks Resource House).
