| 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 |
