Get students thinking like real engineers with this engaging Sink It or Save It! STEM Challenge Journal<\/strong>.<\/p>\n

In this activity, students are challenged to design, build, and test a floating boat<\/strong> using simple materials\u2014while learning key science concepts like floating vs sinking, density, and buoyancy<\/strong>.<\/p>\n

This isn\u2019t just a worksheet\u2014it\u2019s a complete guided STEM experience<\/strong>.<\/p>\n

Students will:
\n\u2714 Ask questions and define a problem
\u2714 Brainstorm and design solutions
\u2714 Build and test their boats
\u2714 Measure and compare results
\u2714 Improve their designs
\u2714 Reflect on their learning<\/p>\n

All structured using the Engineering Design Process<\/strong>, making it perfect for inquiry-based and project-based classrooms.<\/p>\n
