Name______________________________________ Date___________ Friction and Slope Lab
The Challenge: to create a marble maze that will take as much time as possible for the marble to run through the maze from start to finish. 1. What is friction? How does friction affect the speed of an object? Give examples. 2. What is slope? How do you predict slope will affect the speed of an object? Give an example. 3. Using the list of materials you are allowed to use for this project, sort them according to material you think will create more friction (slow down the marble) and less friction (speed up your marble). Material with LOTS of friction
List the type and amount of materials you have chosen to use. (Example: Rubber bands ‐10 Toothpicks ‐20) Materials with LITTLE friction
Draw a diagram of your design. A‐Maze‐ing Marbles Continued 7. What was your theory in creating your design? 8. When you have finished your design, do five “trial runs”. Record your results in the chart below. What is the average time your marble took from start to finish? TRIAL # 1 2 3 4 5 TIME (seconds)
Average time: _______ Seconds 9. What did you discover in examining your design and your classmates’ design? 10. What advice would you give another group who is about to try this experiment? Maliszewski/Alexander 2009
