    When we study density we need to know mass and volume. I make an analogy of mass being amount of students in the room and volume is the size of the room. And then we discuss what if we make the room smaller--would we get more squished or less squished (density). I don't know if this helps you or not but it helps my students visualize it. Also, I would take out the triple-beam balance and have students measure mass and then take out a ruler or graduated cylinder to measure volume. Bring food items to class and have students read the label to find out it's volume (and sometimes mass is on there too) so they get an idea of different volume sizes. Definitely hands on activities exploring mass and volume really helps students to see the difference.
