Make density and buoyancy unforgettable with this hands-on Build a Boat Challenge! In this engaging STEM engineering project, students design and build a foil boat using one sheet of aluminum foil and test how many pennies it can hold before sinking. Students will apply density, buoyancy, mass, and engineering design as they create a blueprint, build their boat, test two trials, collect data, answer analysis questions, and improve their design. This fun and competitive activity ends with the e
