Comparing two different types of cars while making a finish line

Dear Bloggers,

Years 3 and 4 made two identical cars and timed how long they took to move dowan a ramp. The reading were taken 3 times and the students calculated the average.

One car remained untouched, acting as a control, and the other was changed.  Changing one variable at a time, the stuents used a fair test to see whether the changes they made made to the car mader it go faster or not. We then discussed what made made the experimental car travel faster.
