Grade 3 students were introduced to simple tools and design strategies before diving into a trans-disciplinary project (Science & Technology, Social Studies, Mathamatics, Language and The Arts). The culminating activity was to design and build a new landmark for a specific location in Ontario. The new landmark would have to stand the test of time, and would need to serve an important purpose or function. The entire process was spread over several months. A trans-disciplinary unit plan, as well as several templates that may help students to track their progress through the Engineering Design Process have been included.
