Reflection: Adjustments to Practice Rolling into Summer or Elves at Work - Section 4: On Your Mark, Get Set, Go!


When I initially asked students why did the vehicle veer to the right or left, most students would state factors beyond the vehicle system. For example, one student said it was a crack in the floor. Another students said the ramp wasn't straight.

I did not anticipate that students would consider these factors. During our 'debriefing' at the end of the lesson, I scaffolded the discussion to include what vehicle elements could cause the it to veer left or right. 

We also discussed how we could make a more fair test by covering the cracks and checking that the vehicle is facing straight on the ramp. I will be discussing both of these variables when students test the vehicles they build.
