📊 Playground Forces Data Collection

In investigation teams, students conduct their planned fair tests using ramps, marbles, toy cars, string swings, and/or magnets. Each student records at least 5 trials in their bound notebook, including measurements (distance in cm or time in seconds), controlled variables, and detailed notes about setup conditions. Students document any unexpected results or deviations from the plan instead of discarding them, and may include labeled sketches of their setup.
