Scientific Method
Word Definition Pictures
Problem A question to be considered, solved, or answered
Hypothesis An idea about the solution to a problem that can be tested or investigated
Research The method of collecting information and data about a topic being studied
Procedure A set of steps to follow to perform a specific task
Materials The items needed to conduct an experiment
Variable (independent) The one factor changed in the experiment
Variable (dependent) Factor that changes as a result of the independent variable
Data A group of measurements, facts, or statistics recorded about an experiment
Analyze To organize and examine data using narratives, charts, graphs or tables
Conclusion The last part of an experiment where the findings are summarize
Measurement and Metric
Word Definition Pictures
Weight The measure of the force of gravity on an object can change / location
Mass The amount of matter in an object, does NOT change
Volume The measure of how
Density The amount of mass in a certain volume Density = Mass / Volume
Meter The base unit for length in the metric system Meter stick
Liter The base unit for volume in the metric system Graduated Cylinder
Gram The base unit for mass in the metric system Triple-beam balance
States of Matter
Word Definition Pictures
Matter Anything that has mass and takes up space
States of Matter A physical property of matter; solid, liquid, gas, plasma
Phase Change A change from one phase to another by adding/ taking away heat energy
Condensation The process of changing a gas to a liquid by taking away heat energy
Evaporation The process of changing a liquid to a gas by adding heat energy
Freezing The process of changing a liquid to a solid by taking away heat energy
Melting The process of changing a solid to a liquid by adding heat energy
Chemical Change Change where 1 or more substances are transferred into something new
Physical Change Change where the form is altered but NOT transformed into something new
ATOMS
Word Definition Pictures
Atom A small particle that makes up most matter
Element A substance made of only 1 kind of atom/ can NOT be easily divided
Molecule The smallest part of a compound that still has the properties
Compound A substance made of two or more elements are combined chemically
Nucleus The positively charges central core of the atom (P/N)
Neutron An uncharged particle located in the nucleus of an atom
Electron Small/fast invisible, negatively charged particle that travels around the
nucleus of an atom
Mixture Substance formed when 2+ substances come together but does NOT
combine
Pure Substance A substance that can NOT be separated - unique chemical & physical properties
Melting Point The temperature at which a solid melts to become a liquid
Boiling Point The temperature at which a liquid becomes a gas
Energy
Word Definition Pictures
Energy Ability to cause change or motion: to do work
Kinetic Energy Energy in motion or use
Potential Energy Stored energy
Fossil Fuels Combustible organic material derived from the remains of former living things
Convection Transfer of heat by circulation: hot air rises, cold air sinks
Conduction Transfer of heat between touching parts
Radiation Energy emitted as particles or waves
Climate Change Long-term change of the Earth's climate: changes due to an increase / decrease temperature
Conductor Allows heat to flow
Insulator Stops/ slows down the flow of heat
Speed
Word Definition Pictures
Acceleration Change in speed, increase or decrease
Direction The line or path along which something travels
Distance Length of a path an object travels, usually measured in meters
Motion Movement, change of position
Speed Rate of motion calculated by: Speed = distance divided by time
Velocity Description of the motion of an object, both speed and direction
Astronomy
Word Definition Pictures
Eclipse The total or partial blocking of one celestial body by another Sol= Sun,
Lunar = Moon
Ellipse Elongated, closed curve that describes Earth's yearlong orbit around the Sun
Gravity A mutual physical force of nature: causes two bodies to attract each other
Moon Phase Change in appearance of the Moon due to the positions of the Moon, Earth, Sun
Orbit Curved path of a satellite a combination of the satellite's forward movement and
Earth's gravitational pull
Revolution Earth's yearlong elliptical orbit around the Sun 365 1/4 days
Rotation Spinning of the Earth on imaginary axis creates = illusion of day/night 24 hrs.
Tide Regular movement of the level of the ocean caused by the pull of the Sun, Earth and Moon
Tilt The state / position of being sloped
