Variables Unit Vocabulary Crossword Puzzle

QUESTIONS LIST:

• capacity : amount a container holds when filled up.
• density : how close atoms and molecules are packed together.
• mass : the amount of matter that makes up an object.
• volume : similar to capacity. the amount of space a container occupies.
• buoyancy : a force in liquid that pushes an object up.
• oscillation : a repeated swing or swivel action.
• negative : the type of relationship that exists when the independent variable increases and the dependent variable decreases or vice-versa.
• gravity : a force that pulls an object down. in a pendulum it pulls the bob back toward the equilibrium point.
• control variable : things in an experiment that can change but are kept the same.
• positive : the type of relationship that exists when both the independent and dependent variables increase or both decrease.
• special case : the type of relationship that exists when either independent or dependent variable stays the same.
• dependent variable : what is counted or measured during the experiment.
• variable : anything that can change.
• independent variable : the one thing in an experiment that is allowed to change.
• period : one complete swing of a pendulum (away and back).
• matter : anything that takes up space and has mass. all objects are made of it.
• pivot point : the fixed point of a pendulum.
• bob : the mass or weight that is suspended in a pendulum.
• pendulum : a bob suspended from a pivot point so that the bob swings freely.
• inertia : a force that pulls an object out (away from the equilibrium point).
• displacement : movement (if relating to water, it is = the mass of the object that moves the water.)
• equilibrium point : when a bob is at rest.
