Science Basics
A statement that can be tested through an experiment.
What is a hypothesis?
Anything that has mass and takes up space.
What is matter?
Mass divided by volume.
What is density?
The state of matter with a definite shape and definite volume.
What is a solid?
The center of an atom.
What is the nucleus?
Information collected using your senses or tools.
What is an observation?What is the independent variable?
A characteristic that can be observed without changing a substance.
What is a physical property?
The metric unit commonly used to measure mass in our density lab.
What are grams?
The state of matter with a definite volume but no definite shape.
What is a liquid?
The positively charged particle inside an atom.
What is a proton?
The variable a scientist changes on purpose.
What is the independent variable?
The amount of matter in an object.
What is mass?
The tool used to measure the mass of an object.
What is a balance?
The state of matter with no definite shape or volume.
What is a gas?
The negatively charged particle inside an atom.
What is an electron?
The variable a scientist measures.
What is the dependent variable?
The amount of space an object takes up.
What is volume?
The method of finding volume by measuring how much water an object pushes aside.
What is water displacement?
The change from a liquid to a gas.
What is vaporization (or evaporation/boiling)?
The particle inside an atom that has no charge.
What is a neutron?
An explanation based on observations and evidence.
What is an inference?
The ability of a substance to dissolve in water.
What is solubility?
The density of an object with a mass of 20 grams and a volume of 5 cubic centimeters.
What is 4 g/cm³?
The process in which particles spread from an area of high concentration to low concentration.
What is diffusion?
The total number of protons and neutrons in an atom.
What is the mass number?
