A simple lab to test how the speed of dropped coffee filters changes as the height is increased. As students raise the height of the filters, speed will increase (up to a point, known as terminal velocity), where after the speed will remain constant. Students will need to calculate their results, create a distance-time graph and a speed-time graph to represent their data, and write a conclusion of their results.
Materials needed: coffee filters, stop watch, meter stick.
Main topics: calculating speed, graphing distance vs. time, graphing speed vs. time, interpreting graph and lab results.
Quick, easy, and effective in demonstrating and practicing speed. Great for middle school or introductory high school courses.
