Engineering Worksheet: Part 1 Test

Engineering lesson 8: Part 1 test: what engineers do · Set 499 · 40 questions

Engineer's tip (Find the topic, use the idea): Find the topic: invention, branch, design step, limit or goal, testing, teamwork or tools. Use that lesson’s rule — the design process order is ask, imagine, plan, create, test, improve. For number questions, write the calculation before you answer.
