The project has an authentic purpose and a clear audience outside of the classroom. Instruction and learning of important science content is integrated into the project.

Students launch bottle rockets at the end of a physics/math unit, to apply what they have learned.

• A: Project/ Assignment

• B: PBL

Answer explanation

This is a fun activity—but it’s not a PBL project. It’s missing many key elements of “main course” projects. (For more details on what to include in projects, check out the Essential Project Design Elements of Gold Standard PBL.)
