On our upcoming matter test, students will have to calculate the density of an object given the mass and the volume of the object. I just put a quick practice activity together for any students who are interested in reviewing this skill:
The video embedded in the practice activity goes into deeper detail, demonstrating how to calculate mass if given the density and the volume of an object. That skill isn’t covered on the test. The only calculations your children will have to do are the calculations modeled in the first few minutes of the video: Determining density given the mass and volume of an object.
Hope this helps,
