I created this discovery-based geogebra activity for my standard 8th grade math class to work through the question of how changing heights and radii affects the volumes of different solids. The activity involves students changing different dimensions of solids and observing then explaining the affects the changes had. It relies on students already knowing the volume formulas and perhaps having a general understanding of where those formulas came from.
This resource includes the powerpoint I used for the class period (including a warm-up and closing graphic organizer) and an editable packet of guiding questions to accompany the activity. The activity itself is public on the geogebra website. This resource is the printable materials and powerpoint that I have made to go along with it.
**I did not create the appellates on geogebra. Their creators are cited on the webpage. I compiled the various appellates, edited them to suit the activity, and then added questions.
