Basics
A possible, testable explanation for one or more observations or a suggested testable answer to a question.
What's a hypothesis?
The smallest chemical unit of an element
What's an atom?
The number of protons in an atom
What is an atomic number?
A point against which motion is measured.
What is a reference point?
After analyzing data scientists write detail explanations that include graphs, results, errors, and conclusions.
What is a lab report or scientific report?
The gathering of information using senses or the aid of instruments.
What's an observation?
The smallest unit of a chemical compound, composed of two or more atoms bonded together
What's a molecule?
The ratio of a substances mass to its volume
What's density?
The distance an object travels plus the direction from the starting point.
What is displacement?
The tendency for an object to change its velocity.
What is inertia?
A factor that can change in an environment.
What's a variable?
Anything that has mass and takes up space
What's matter?
An atom or group of atoms that has a positive or negative charge
What's an ion?
The change in an objects velocity over time
What is Acceleration?
This quantity is measured in meters per second and tells you how quickly and in what direction the object is moving relation to a reference point.
What is velocity?
A logical conclusion drawn from observations, previous knowledge, and available information.
What's an inference?
The energy an object has due to its motion
What's kinetic energy?
Compounds made of only two elements
What's a binary compound?
The ratio of the total distance traveled to the total time of the trip.
What's an average speed?
Frictional force that acts upon a stationary object that opposes the initiation of motion.
What is Static friction?
A well-tested explanation of a phenomenon in the natural world.
What's a Scientific Theory?
The force of attraction between molecules of the same substance so that they tend to stay together.
What is cohesion?
A chemical reaction in which two or more substances react to form a single compound
What's a synthesis reaction?
A physical measurement that contains only magnitude and does not contain directional information.
What is a scalar quality?
The careful, systematic study and investigation of a subject to discover new information, facts, or principles.
What is Research?
