To throw away or get rid of something Dispose
To keep something from happening Prevent
Steps followed during an experiment Procedure
The part of an experiment that you change Variable
Problem, Hypothesis, Materials, Procedure, Observations, and Conclusion Scientific Method
Noticing something about the world around you Observation
Using clues to find the answer Inference
To put into groups Classify
The scientific process used to answer questions by collecting data; you change one variable and everything else stays the same Investigation
An educated guess that is backed by reasonable information Hypothesis
Information found during an investigation that is recorded and organized Data
The end of the investigation where you determine if your hypothesis was correct Conclusion
How much matter is in something. Measured in grams using a triple beam balance and always stays the same Mass
How much space something takes up. Measured in liters or milliliters. Example: Graduated cylinder Volume
Measures temperature. How hot or cold something is in Celsius Thermometer
The ability to float. Typically due to its shape or because it is less dense than water Buoyancy
The amount of molecules in matter that effect whether or not it is buoyant Density
The measurement of the pull of gravity of an object Weight
A force that pulls towards the center of a heavenly body Gravity
Parts of an object that can be observed using the five senses Physical Properties
Solid, liquid or gas Phases or States of Matter
A change from one form to another without creating a new substance (ice melting, cutting paper, shredding cheese) Physical Change
A change that produces a new substance (metal rusting, vinegar and baking Soda reaction, food molding) Chemical Change
Anything that has mass and takes up space (solid, liquid, gas) Matter
A particle of matter made up of two or more atoms Molecules
The basic unit of matter Atom
Matter that retains a definite size and shape: The molecules are packed together tightly Solid
Matter that retains a definite size, but not a definite shape Liquid
Matter that does NOT retain a definite size or shape. The molecules are far apart and move rapidly Gas
100° C Boiling Point of Water
0° C Freezing Point of Water
The temperature at which point a substance changes from a solid to a liquid. 0° C is the melting point of water Melting Point
The point at which water turns to water vapor Evaporation
The point at which water vapor turns back to water Condensation
Property of matter that does NOT change. It stays the same Constant Property
The force of attraction or repel between 2 objects usually metal (iron, nickel, Cobalt & steel) Magnetism
A force that causes objects to pull together Attract
A force that causes objects to push back or away from one another Repel
Two or more substances that when mixed together can be separated easily (trail mix, fruit salad) Mixture
Two or more substances that when mixed together can NOT be separated (salt water, sweet tea) Solution
Something that can be dissolved (sugar, salt) Soluble
The liquid that does the dissolving (water) Solvent
A process using a strainer to separate the larger particles in a mixture Filtration
Allows the dense materials to sink to the bottom Settling
To add solid or gas to a liquid so that the particles get so small you can no longer see them Dissolve
The individual substances added to a mixture Ingredients
Stored energy. No motion is taking place. This depends on an object's position. Ex. A ball NOT rolling, a still roller coaster at the top of the track, a book on a shelf Potential Energy
The energy of motion. This depends on mass and speed. Ex. A book falling or a ball rolling Kinetic Energy
The force in which two things rub against each other (It causes things to heat up and slow down) Friction
A push or a pull Force
To apply a force on the Surface of an object Pressure
A change in the position of an object Motion
The ability to do work (potential, kinetic, chemical, mechanical, electrical, heat, light and sound) Energy
Work done from something that with moving parts Mechanical Energy
A material that allows heat energy or electricity to pass through it easily (usually metal) Conductor
A material that does not let heat energy or electricity pass through it easily (plastic, rubber, cloth, wood, Styrofoam) Insulator
Another word for heat Thermal
Energy produced by the Sun Solar Energy
The movement of thermal energy through space Radiation
Able to withstand heat Heat Resistant
To take in or soak up Absorb
The movement of heat energy through liquids and gases in currents. Heat rises when it cools then it sinks (lava lamp) Convection
The flow of electrons through a conductor or path. Will produce light, heat or sound Current Electricity
A closed path that electrons flow through, made up of a source, path, switch and resistor Circuit
Electric charge that builds up on an object and instead of flowing as a current, it creates a spark Static Electricity
Electricity from a battery, solar, cell, fossil fuels or wind generators Source/Cell
A wire that a current flows through Path
Turns a circuit on and off Switch
The object you want to work (light, TV, radio) Resistor/Load
temporary magnet made of Wire wrapped around a piece of iron hooked up to a battery Electromagnet
An electric circuit in which electrons have only one path to take. If one light goes out or is removed, they all go out Series Circuit
A circuit where the electrons have many paths to take. If one light is removed the other lights will still work and will get brighter Parallel Circuit
The bouncing off of light rays from a surface (Enters and exits at the same angle) (Mirror, still water) Reflect
The bending of light as it moves from one material into another (Rainbows, pencil in water) Refract
The mixture of Colors of White light broken into their individual colors of the rainbow (ROY G BIV) Visible Light Spectrum
Thicker in the middle, makes objects look bigger Convex Lens
Lens is thinner in the middle, makes objects look smaller Concave Lens
Clear, all light can pass through Transparent
Cloudy, some light can pass through (Wax Paper, Stain Glass Window) Translucent
No light can pass through (Trying to look through a wooden desk) Opaque
Created when molecules vibrate. The closer the molecules the better sound travels. Solid Carries sound the best Sound
Back and forth motion of a substance that produces sound Vibration
