Investigating Volume

I found a fun activity to challenge students to investigate what volume is. My students were successful in using the algorithm, but, did they really understand the difference between volume and capacity?

I must admit, I wanted to make this challenging by using the word ‘vessel’ instead of box. One pair of students wanted to make a cylinder, while others used origami skills to make a ‘sturdy’ box…but were they using as much paper as possible?

I told students that we would experiment with puffed rice and MAB (pictured) before they began. I was surprised to see one pair make a cylinder but they rethought their decision when they tested their vessel with cubes! What happens to all of the empty space? Is the calculation accurate?
