This investigation allows learners to see the effect on volume when you change one, two or all three dimensions. It was designed as a self-study activity (and can also be used as an assessment but there is no investigation in term 3/4) but I have also used it very successfully as the backbone of my lesson.
Learners need to be familiar with the Volume of a prism, pyramid and cylinder.
BONUS: I have added notes about 3-dimensional shapes as a free extra. I use this as the introduction to the chapter. Learners keep the info sheet next to them for the rest of the chapter in order to look up the formulas quickly.
