Term | Definition |
energy | the ability to cause changes in matter |
potential energy | energy that an object has because of its position or its condition |
kinetic energy | the energy an object has because of motion |
electrical energy | energy that comes from electric current |
mechanical energy | the total potential and kinetic energy of an object |
chemical energy | energy that can be released by a chemical reaction |
thermal energy | the total amount of kinetic energy of the particles in a substance |
temperature | the measure of the average energy of motion of particles of matter, which we feel as how hot or cold something is |
heat | the energy that moves between objects of different temperatures |
static electricity | the buildup of electric charges on an object |
electric current | the flow of electric charges along a path |
conductor | a material that lets heat or electricity travel through it easily |
insulator | a material that does not let heat or electricity move through it easily |
circuit | a path along which electric charges can flow |
series circuit | an electric circuit in which the electrical charges have only one path to follow |
parallel circuit | an electric circuit that has more than one path for the electric charges to follow |
balance | a tool used to measure the amount of matter in an object, which is the object’s mass |
control | the experimental setup to which you will compare all other setups |
evidence | information collected during a scientific investigation |
experiment | an investigation in which all the conditions are controlled to test a hypothesis |
investigation | a procedure carried out to carefully observe, study, or test something in order to learn more about it |
microscopic | too small to be seen without using a microscope |
opinion | a personal belief or judgment based on what a person thinks or feels, but not necessarily based on evidence |
Science | the study of the natural world through observation and investigation |
scientific method | the different ways that scientists perform investigations and collect reliable data |
spring scale | a tool used to measure force |
variable | any condition that can be changed in an experiment |
accurate | in measurements, very close to the actual size or value |
matter | anything that has mass and takes up space |
volume | the amount of space something takes up |
solid | the state of matter in which a substance has a definite volume and a definite shape |
liquid | the state of matter in which a substance has a definite volume but no definite shape |
gas | the state of matter in which a substance does not have a definite shape or definite volume |
relative density | it determines whether one substance will sink or float in another substance |
solubility | the ability of a substance to dissolve in another substance |
mixture | a combination of two or more different substances in which the substances keep their identities |
solution | a mixture that has the same combination throughout because all its parts are mixed evenly |
force | a push or pull, which may cause a change in an object's motion |
gravity | the force of attraction between objects; such as the attraction between Earth and objects on it |
friction | a force that acts between two touching objects and that opposes motion |
balanced forces | forces that cancel each other out, because they are equal in size and opposite in direction |
unbalanced forces | forces that cause a change in an object's motion because they don't cancel each other out |
