Identify which of the following are experiments, and if so, what kind of experiment.
Describe what should you be looking for in the data.

TESTING PROCESSES
Myth busters episode on whether it is possible to shoot a ball out of the back of a car at the same speed the car is moving forward so that relative motion is zero.

What was the investigative question?
What type of experiment was used?
How many trials were competed OR how many experimental units?
How was the data collected? What measurement tools were used?
What analysis was completed?What conclusions were made?
IDENTIFY AND DESCRIBE STEPS IN THE INVESTIGATION
