Description

Get students thinking like real engineers with this engaging Sink It or Save It! STEM Challenge Journal.

In this activity, students are challenged to design, build, and test a floating boat using simple materials—while learning key science concepts like floating vs sinking, density, and buoyancy.

This isn’t just a worksheet—it’s a complete guided STEM experience.

Students will:
✔ Ask questions and define a problem
✔ Brainstorm and design solutions
✔ Build and test their boats
✔ Measure and compare results
✔ Improve their designs
✔ Reflect on their learning

All structured using the Engineering Design Process, making it perfect for inquiry-based and project-based classrooms.
