    student – erasable magnet boards work
—  Student designs identify where instruction
    was missing or weak
—  Provide a re-usable device
—  Make the job go faster with icons
—  Icons get returned to the board
—  Inexpensive and effective

—  Challenge 1: make a realistic portable SHW
    teaching platform that teaches the WHYs
—  Challenge 2: Make it constructible so
    students can put it together and then
    watch what happens & diagnose & fix:
      ◦  Leaks, entrained air & cavitation
      ◦  Siphon actions
—    Challenge 3: Make it so it will work outside
      and get HOT so students can see:
      ◦  Flow rates & temperature deltas
      ◦  Pump pressure patterns
      ◦  Drainback flow regimes
      ◦  HX characteristics
—    Challenge 4: Make it see through

—  Comprehension     – this is obligatory
 ◦  Understanding the whys before the hows
 ◦  Illustrating the theory with DIY tools
 ◦  Math (with sensitivity runs) = Whys
 ◦  Students explain what you just presented
 ◦  Team exercises for inter-student learning
 ◦  Manipulatives are an excellent and cheap tool
 ◦  Demo devices are excellent learning tools

—  Contexturalizeyour content to their
 lives and experience
