Period 8 Station 3
Focus Question Will the type of surface affect how far
the object will push the note card?
hypothesis
If we use the counter top , the object will push the note card farther!
Our object on the counter top
Supplies 2 Science books 1 Marble 2 rulers 1 roll of Tape 1 piece of construction paper 5-6 note cards
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.
Independent Variable We are going to change the texture of
the surface.
Dependent Variable
We are measuring the distance the marble pushes the note card.
Constants Keep the size of the ramp the same Starting point of marble Starting point of note card
Starting point
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.

Counter Top (cm)Contuction Paper (cm)
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?
