A class wants to prototype a solution to carry a cup of water across a model track using classroom materials. Evidence: the class will record measurements before deciding. Which prototype plan uses simple materials appropriately?
A
Using the planned measurements, build a full-size permanent structure for carrying a cup of water across a model track before doing any prototype test.
B
Using the planned measurements, build a simple model of the balanced tray with raised edges, test whether it reduces spilling while staying balanced, and record results for the goal of carrying a cup of water across a model track.
C
Using the planned measurements, use unsafe tools to make the balanced tray with raised edges faster without adult permission.
D
Using the planned measurements, draw only a logo for the balanced tray with raised edges and skip testing the prototype.
