This is the perfect LAB for Calculating Average SPEED! Students will race toy cars down a ramp to compare each Trial's Speed with the Average SPEED of all Trials. Always in Scientific Method, this LAB allows for Self-Directed, Hands-ON work with Calculating Speed and Average Speed. It also has students draw a Force Diagram of the Toy Car perched at the top of the ramp, as well as inference where there are Balanced and Unbalanced Forces on the car. I use this LAB every year during my Calculating Average SPEED Unit, and it also has students GRAPH their Trials and compare them to the Average SPEED of all the Trials. All that is needed is: toy cars, "ramps" of folders, books, or boards, and a timer, stopwatch, or clock with a second hand. I have even left a "graph paper" area for calculations so that students will be reminded to used lined paper for calculations! I hope this helps you ROCK the Science in your CLASSROOM! It will be part of my new Calculating SPEED complete 5E's+way more UNIT and LAB Set, or you can get it by itself here! Let me know if I can help in any way!
