This Instructable integrates a MyStemKits problem-based learning activity aligned to the NGSS and Common Core Standards. This model eliciting activity (MEA) will help students tackle real-world problems as they balance budgetary constraints with finding the most-optimal design, all while overcoming unforseen circumstances that may change the procedure students use to determine the best solution. In the end, students are challenged to design and test their own boats, using Tinkercad to model a 3D-printable boat.

Estimated Instructional Time: 3-4 class periods, 50 minutes each
Estimated Boat Design Time: 1 class period, 50 minutes
Lesson Plan Abstract:
Students will be engaged in a hands-on activity to test the efficiency of various cargo boat designs. In testing, students will collect data using 3D-printed boat models and determine which design is superior in terms of total cargo mass. Students will explore scientific approaches, engineering design, and mathematical applications, namely developing a procedure to select a boat while meeting several constraints. In part 2 of the activity, students will have the opportunity to design their own boat prototype.
