Five Fast EiE Teacher Tips for Engineering "Marvelous Machines"

Posted by Cynthia Berger on Tuesday, November 24, 2015

2015.11.24_EiE_Simple_Machines.jpgIf you’re teaching “Marvelous Machines: Making Work Easier," EiE's industrial engineering unit, our collaborators at the Science Museum of Minnesota (SMM) have some tips for teaching Lesson 4 (“Improving a Factory Subsystem"). The lesson calls for kids to use what they’ve learned about simple machines in science class to design a model “loading dock” that helps a potato chip factory run more smoothly. Try these five fast tips to save time, reduce classroom chaos, and most importantly, enhance your students’ learning!

  1. 2015.11.24_eie_edp.jpgTake time to IMAGINE: Lesson 4, part 1 engages students in the IMAGINE step of the Engineering Design Process as they design and build a system for lifting potatoes onto a factory belt. Schedule this activity at the end of the day . . . and give extra time the next day for brainstorming and imagining. This approach reduces the pressure on students to roll with the very first idea they think of. You’ll see a greater variety of more imaginative designs.
  2. Make testing part of the PLAN: After students IMAGINE their design, the next step is to get their creative ideas down on paper as they PLAN their design. At this stage, it’s useful to have a couple of test stations already set up, so teams can try out their rough-draft designs before the “official” testing step.
  3. Share data to IMPROVE: Lesson 4, part 2 calls for each group of students to test the loading dock system they designed. Rather than having each team conduct their tests independently, let the whole class observe ALL of the loading dock tests, and chart these results. Your students will be able to use these observations to inform the IMPROVE step.
  4. Remember: It’s not a contest! Students may want to treat the tests as a competition. Remind them that engineers collaborate! The goal is to improve the team’s score, not to compete against other teams. Besides, each team has been assigned a different simple machine (inclined plane, single pulley, double pulley, and so on), so each team faces different constraints.

SMM staff say they find the videos for Lesson 4 of Marvelous Machines particularly helpful! You'll see students who have come up with quite a variety of designs for their “Loading Dock” subsystems, some of which incorporate unconventional materials (for example, tape, or a stack of books).

2015.11.24_Marvelous_Machines.jpgThese tips for "Marvelous Machines" are just a small sample of a very large (and very handy) collection of EiE Teaching Tips offered by SMM, one of our longtime professional development collaborators. Check out the great teaching tips they’ve compiled for these other EiE units:
