100
a list of steps you follow in a scientific investigation
What is procedure?
100
a simple machine with a wheel with a rope around it; fixed and movable ones are used to lift heavy objects
What is a pulley?
100
A push or a pull
What is force?
100
equal forces acting on an object
What is balanced forces?
100
a force that attracts objects to each other; this force holds you to Earth's surface
What is gravity?
200
the process of asking questions and then doing careful investigations to find the answers to those questions
What is scientific inquiry?
200
a simple machine with an inclined plane wrapped around a rod
What is a screw?
200
A change in position.
What is motion?
200
a force that works against motion, such as the force between a bicycle's tires and a sidewalk
What is friction?
200
the tendency of an object to resist a change in motion
What is inertia?
300
an idea about what may happen in the future; use conclusions and inferences to make predictions
What is prediction?
300
a simple machine with an inclined plane that is used as a tool for cutting or separating things
What is a wedge?
300
speeding up, slowing down, or changing direction
What is acceleration?
300
the measure of the amount of matter in an object; the more mass an object has, the greater its force of gravity
What is mass?
300
anything that has mass and takes up space
What is matter?
400
a graph that shows how data change over time
What is line graph?
400
a simple machine made of two wheels;
What is wheel and axle?
400
a force or push; the state of being in motion
What is action?
400
how far a moving object travels. It is measured in units such as meters and kilometers
What is distance?
400
two unequal forces acting on an object and causing a change in motion
What is unbalanced force?
500
a possible answer to a scientific question; an idea about what might happen in an experiment
What is hypothesis?
500
a bar that turns around a point called a fulcrum; example - crowbar
What is a lever?
500
to pull toward
What is attract?
500
an object's speed in a particular direction
What is velocity?
500
the distance an object moves in a given amount of time
What is speed?
