6th Grade Energy Voc
6th Grade Science - Miss. Sommer @ Edison Elementary
| Question | Answer |
|---|---|
| Hypothesis | an intelligent guess made before an investigation |
| Theory | an assumption based upon gathered information |
| Constants | all the things that must be kept the same to make an experiment fair and valid |
| Independent Variable | the one thing an experimenter changes in an experiment |
| Dependent Variable | the result the experimenter is looking for |
| Controlled Experiment | experiment with only one independent variable |
| Mean | a number found by calculating the sum and then dividing by the number of figures in a set of data |
| Mode | the number that occurs most often in a set of data |
| Energy | the ability to do work or cause change |
| Potential Energy | energy from position or condition |
| Kinetic Energy | energy from motion |
| Cycle | a series of steps that repeats |
| Force | a push or pull |
| Friction | a force that acts to oppose sliding between two surfaces that are touching |
| Speed | distance divided by time |
| Matter | anything that has mass, takes up space; can be a solid, liquid or gas |
| Mass | the amount of matter in an object |
| Weight | a measure of how hard gravity pulls on an object |
| Gravity | a pull toward the center of an object |
| Inertia | the tendency of an object to resist a change in motion |
| Momentum | a measure of how hard it is to stop an object (depends on the object's mass and velocity) |
| Velocity | speed and direction of a moving object |
| Newton's First Law | an object at rest will stay at rest, an object in motion will stay in motion, in a straight line, at a constant speed unless some force acts upon it |
| Newton's Third Law | states that forces act in equal but opposite pairs OR for every action there is an equal but opposite reaction |
| Volume | the amount of space occupied by an object |
| Meniscus | the bottom of the curved surface of a liquid in a graduated cylinder |
| Density | mass divided by volume |
| Displace | to push out of the way |
| Buoyant force | upward force exerted by a fluid on any object in that fluid |
| Archimedes Principle | the buoyant force on an object is equal to the weight of the fluid it displace |
| Fulcrum | the point on which a lever turns |
