magnetic force: the push or pull of a magnet on another magnetic material
properties: qualities or characteristics
permanent magnet: an object that keeps its magnetism after it has been magnetized
attract: to draw objects together
repel: to push apart
magnetic field: an area around a magnet where the magnetic force exists
compass: an instrument used to determine geographic direction on Earth
natural magnet: iron ore called magnetite that has naturally magnetized (lodestone)
temporary magnet: a magnet that does not keep its magnetism
electromagnetism: the magnetism produced when an iron rod is magnetized by an electric
current passing through a wire that is coiled around the rod.

Vocabulary for the week of December 10th
gas: matter that has no definite size or shape, but fills up an entire container
liquid: matter that has a definite size, but not a definite shpe (shape changes w/ container)
solid: matter that has a definite size and shape
condensation: the process in which matter changes from a gas state to a liquid state
evaporation: the process in which matter changes from a liquid state to a gas state
chemical change: change in matter where the chemical properties are changed so a new substance is formed; the
new substance cannot be changed back into its original form

Vocabulary for the week of November 5th
Proton - part of an atom that stays in the nucleus and has a positive charge.
Neutron - part of the atom that stays in the nucleus and has no charge
Electron - smallest part of an atom, has a negative charge and circles the nucleus at high speeds
Ion - an atom that has lost or gained an electron and now has a positive or negative charge
Current - flow of electricity
Circuit - a pathway for electricity to follow
Open Circuit - a pathway with a break that stops electrons from flowing
Closed Circuit - a complete pathway of electrons
Series Circuit - Circuit with only one path available for electrons to follow
Insulator - something that does not allow electrons to flow through it
Conductor - something that allows electrons to pass through it
Static Electricity - electricity that occurswhen electrons build up to make a negative charge on something and can
attract something with a positive charge
Alternating Current - current in which electrons flow in both directions
Direct Current - current in which electrons flow in one direction
