I designed this investigation for my grade 9 learners, after our area was hit by some horrific fires. The investigation was designed in such a way that learners can work through it by themselves, with no preparation or help from the teacher. Everything they need to know is on the investigation, but I left it in Word format so that you can edit it to include locations familiar to your learners.
The questions are set in such a way that learners get to use the Speed/Distance/Time formula in different ways.
