Students were conducting a force investigation by rolling a golf ball down a ramp made of wood with different surfaces. They noticed that the golf ball didn't roll as far down the ramp with carpet on the wood as the ramp made of just wood. What causes this to happen?
acceleration
magnetism
friction
mass
Student scientists were rolling a marble down a ramp and measuring how far it rolled. It rolled 56 centimeters. What should the students do to ensure that is the accurate distance?
remeasure to see if that is correct
test different size marbles and measure how far they roll
raise the ramp to different levels and test the same marble by rolling it down
test the same marble by letting it go in the same place several more times
The picture shows student scientists conducting a force investigation. The picture shows the first trial. If the students added another weight and retested it again, what would their focus question be?
Does gravity affect force?
Does mass affect force?
Does friction affect force?
Does volume affect force?
Students conducted an investigation in which they measured the distance a toy car traveled after rolling down a ramp covered with sandpaper or wax paper. Which of these questions can the students answer by analyzing the results of their investigation?
How does changing the height of a ramp affect the distance of toy car rolls?
How does changing the surface of a ramp affect the distance of toy car rolls?
How does mass affect the distance of toy car moves after rolling down a ramp?
How does the design of a toy car affect its movement after rolling down a ramp?
If a student has two magnets, how might it be determined which magnet is stronger?
measure the length and mass of both magnets
submerge each magnet in a bowl of water
examine each magnet to determine the north pole
count how many paper clips each magnet can lift
Match each word with the correct definition.
A well-researched prediction
Hypothesis
The things that do not change in an investigation
Constants
A variable that changes in an investigation
Independent Variable
The variable that results from the change and can be measured or observed in an investigation
Dependent Variable
A set of steps followed to answer a testable question
Procedures
Identify the independent variable in the investigation.
Height of the ramp
Size of the wheels
Distance the car traveled
Speed of the car
Identify the dependent variable in the investigation.
Height of the ramp
Size of the wheels
Distance the car traveled
Speed of the car
Identify two constants in this investigation.
Height of the ramp
Size of the wheels
Distance the car traveled
The car
Suppose that the students added ice as a surface the car could travel on. Which result would you expect to be a distance that the car would travel on the ice in this investigation?
15 cm
35 cm
50 cm
66 cm
