Surface A
Surface B
Surface C
Surface D
A student sets up an experiment using the ramp below to test how
friction would affect how far a car would travel after leaving a ramp.

the height of the ramp
the color of the car
the mass of the car
the type of surface on which the car rolls

Friction
Opal wants to conduct an experiment on some steel balls that are different masses and sizes. She has books, ramps and different steel balls. Opal wants to test this question: Will the steel ball with the most mass travel to the bottom of the ramp fastest?
Which setup should Opal choose to help her test this question?
A student wants to test the force of magnetism by placing objects on top of a piece of cardboard and then moving them with a magnet placed under the cardboard.
Which items will help the student with this investigation?
A paper clip, a thumbtack, and a toothpick
A paper clip, a piece of paper, and iron filings
A piece of foil, iron filings, and a nail
A nail, a paper clip, and a iron filings
A student is conducting an experiment on magnets. The picture below shows the student holding magnet 2 and pushing it towards magnet 1.
Which of the following will most likely happen to magnet 1 as magnet 2 is moved closer?
Magnet 1 will move under magnet 2.
Magnet 1 will move toward magnet 2.

gravity
Students in a science class are conducting an investigation to determine the amount of force needed to move a 10 kg mass. Their teacher instructed them to conduct the investigation 3 times and record their data with each trial.
Why would the teacher want the students to do the investigation more than one time?
To help them understand their results
So they could practice their procedure
To increase the reliability of their results
Class time was too long to only do the investigation once
