Task · part of 2. Energy forms and conversions: explain three, then build one
2(b). Build a system that makes at least two energy conversions
Required
And explain it to your counselor. Two conversions, not one, which is what rules out the simplest builds.
Notes and warnings
Note. AT LEAST TWO conversions, which is the constraint that matters. A solar cell driving a motor is two (light to electrical, electrical to mechanical). Anything that just moves energy from one place to another without changing its form is none.
