Method Write a 6 step (minimum) method to describe how to obtain valid results for the ramp experiment. 1. First we set up the ramp at a height of 10 cm. 2. Then we practiced to identify any problems. 3. We timed how long it took for the car to travel down the ramp. 4. We repeated this 3 times in order to identify anomalies and calculate a mean. 5. We changed the height and repeated steps 3 and 4 6. We did this every 10 cm between 5 cm and 50 cm
