Below are the steps to construct the four different 3D objects.
After students construct all four geometric shapes, have them complete the accompanying worksheet which basically asks them to measure the dimensions and determing the volume of the figures using the formula for volume of a rectangular prism: V = l x w x h and volume of a cylinder: V =
πr
²h.
Next, hand each group a bowl of popcorn and a cup for transferring the popcorn.
Suggest to students that one hold the rectangular prism as the other fills the
tall prism without spilling the popcorn into the shorter one. If availability
allows, watch students during this part of the activity to see their reactions.
They can now compare their answers for volume with actually how much popcorn fits into each figure. Have them tie everything togather by asking well thought of questions and have them explain what they learned from the investigation.
Overall, this lesson allows students to explore how volume effects different geometric figures.
