  1. Speeding Ticket By: the Purple People Eaters (Bailey Killman, Adrianna Martins, Maddy Pate, Jessie Longbrake) Period 8 Station 3

  2. Focus Question • Will the type of surface affect how far the object will push the note card?

  3. hypothesis • If we use the counter top , the object will push the note card farther! Our object on the counter top

  4. Supplies • 2 Science books • 1 Marble • 2 rulers • 1 roll of Tape • 1 piece of construction paper • 5-6 note cards

  5. BACKGROUND information • We know… • Friction is created when two or more surfaces/ objects are touching and turn KE into thermal energy. • PE (Potential Energy) is based on position and mass. • KE (Kinetic Energy) is based on speed and mass. • Newton’s law of conservation say’s that energy can’t be created or destroyed. But can change in to a different type of energy. • Gravity is the force that pulled the object down the ramp. • We saw potential energy when the marble was on top of the ramp. When gravity pulled the marble down the ramp the marble’s Potential energy decreased, as the marbles Kinetic energy increased. Although we didn`t feel the thermal energy, we saw friction slowing the note card down. We witnessed Newton’s law of conservation when the marbles PE turned into KE.

  6. Independent Variable • We are going to change the texture of the surface.

  7. Dependent Variable • We are measuring the distance the marble pushes the note card.

  8. Constants • Keep the size of the ramp the same • Starting point of marble • Starting point of note card Starting point

  9. Procedure • Step 1: We gather all our supplies • Step 2: We will put the ruler at 25 cm • Step 3: We always make sure the index card is against the ruler every trial or when we change the surface. • Step 4: Make sure the marble starts at 6 cm • Step 5: Remembering our safety during the lab.

  10. Our Data Table

  12. Conclusion • If we use the counter top the object will push the note card farther than on construction paper. Our hypothesis was wrong. Our data tells us the opposite on the construction paper the object went 7cm (that’s the average) while on the counter top it only went 6 cm. What really happened was the friction of the construction paper let the marble push the note card farther while the counter top had more friction that stop the note card faster. What will happen if we use wax paper and Jell-O?
