Variable controlled or manipulated by the scientist during an experiment or investigation.
Independent Variable
This cannot be broken down into simpler substances by chemical reactions.
Element
any substance with a pH less than 7. Tastes sour.
Acid
A pull force that exists between any two objects that have mass.
Gravity
A factor, trait, or condition that is affected when another factor, trait or condition is changed in a scientific experiment. What is being measured in the experiment.
Dependent Variable
Two or more elements chemically combined
Compound
any substance with a pH higher than 7. Tastes bitter.
Base
Speed and direction of an object.
Velocity
Anything that is held constant (or unchanged) during an experiment. It is not a point of interest to the experiment but is controlled because it could influence or change the outcome.
Control Variable
Pure Substance
pH of 7. Example: Water
Neutral
a change in the position of an object compared to another object
Motion
A prediction based on background knowledge saying what is expected to happen in an experiment; an explanation as to why something happened based on what was observed
Hypothesis
A mixture that is the same throughout
Homogeneous Mixture
When an acid and base combine, they create this type of reaction.
Neutralization reaction
Gravity, Electricity, Magnetism
A plan of inquiry that uses science process skills as tools to gather, organize, analyze, and communicate information.
Scientific Method
Mixing gravel, pebbles, and sand in one container results in this.
Heterogeneous Mixture
a scale with a range of 0 to 14 that is used to measure the acidity or alkalinity of a solution
pH Scale
a force that opposes the motion of a body across a surface or through a gas or liquid.
Friction
