ability to react
When a substance has the potential to react with acid, oxygen or water; a chemical property.
The smallest unit of matter. ex. a carbon atom
a change in matter that results in the formation of new substance with new properties
a property of matter that describes a substance based on its ability to change into a new substance with different properties; reactivity
a process in which chemical bonds are broken and atoms rearranged. During the process a new substance is formed.
2 or more elements combined to make something new,
Ex. Na (sodium) + Cl (chlorine) = NaCl (salt)
To change from a gas to a liquid; a physical change.
The measurement of how much mass of a substance is contained in a given volume; compactness of matter.
A pure substance that cannot be broken down into smaller parts. Composed of identical atoms.
To change from a liquid to a gas; a physical change.
Ability of a substance to ignite, causing fire or combustion; chemical property.
A state of matter with no definite shape or volume; a physical property.
A state of matter that has a definite volume but no definite shape; a physical property.
The amount of matter in a substance; a physical property.
Anything that has mass and occupies space; a physical property.
To change from a solid to a liquid. Phase Change; a physical change.
A chemical reaction in which a substance, such as iron, combines with oxygen to form a new substance.
A change in the state of matter. ex. going from a solid to a liquid; a physical property.
A change in matter that does not result in a new substance or change of identity.
A property of matter that can be observed or measured, without the identity being changed.
A state of matter distinct from solid or liquid or gas and present in stars and fusion reactors.
The substance(s) that are formed/released in a chemical reaction.
A state of matter that has a definite volume and a definite shape; a physical property.
State of Matter or Phase of matter
The state in which matter can exist: solid, liquid and gas; a physical property.
The measure of the amount of thermal energy in a substance; a physical property.
The appearance and feel of a surface; a physical property.
The amount of space an object takes up; a physical property.
Finding similarities or differences between groups - no control group
Explain the results of the experiment and make inferences about what you think happened.
The group that is not changed in an experiment, used for comparison to the experimental group. The IV is not changed.
Variables in an experiment that are kept the same so they do not affect the results.
Table that organizes data collected during an experiment.
The variable being measured in an experiment, called the DV.
Collecting data by observing - no IV, DV, or hypothesis.
The group where one variable is changed on purpose. The IV is changed.
An investigation that includes all the parts of the scientific method; such as the IV, DV, hypothesis, constants, and controls
Visual representation of data that can show trends or comparisons.
Educated prediction; what you think will happen during an experiment.
The variable in an experiment that is manipulated or changed by the scientist, called the IV.
A guess. To assume something is true, usually based on reasoning or previous experience.
A fact. Act or power of noticing something by using one or more of your senses.
A well-defined question answered through performing an experiment. Written: How does the __IV__ affect the __DV__?
Assigned to a number to express the method of measurement used (ex. cm)
A component of the experiment that is changed, measured or kept constant in an experiment.
The living or once living material in an ecosystem. ex. Dead trees, yard clippings, wood chips, bark.
Energy stored in the chemical bonds of molecules and compounds... energy that is given off during a chemical reaction. ex. A battery, a match (light/ heat), burning coal, gas in a lawnmower
A container in which plants and other organic matter decay to be later used by gardeners as a fertilizer to enriching soil.
Conservation of Energy
Energy is conserved. This means that energy cannot be created or destroyed, it transforms from one form of energy to another. ex. radiant to electrical
The break down or rotting of organic matter through the action of bacteria or fungi; decomposition.
Energy made available by the flow of electrons through a conductor.
The ability to do work or cause change. ex. types of energy: Hydroelectric energy, Solar energy, Nuclear energy.
Energy-rich substances formed from the remains of dead plants & animals. ex. Coal, oil, petroleum (gas) & other natural gases.
Energy from the heat in Earth's interior.
Potential energy associated with gravity. This varies with height. Greater height = greater gravitational potential energy
Any living or nonliving thing in the environment of which there is a limitless supply. ex. Sun, Soil, Water
The energy of motion.
Energy from the motion of matter. ex. a moving toy (*May be stored like in a spring or stretched rubber band.)
A natural resource that is not replaced as it is used because it takes hundreds of millions of years to form. ex. Fossil fuels (coal, oil, & natural gas).
The energy stored in the nucleus of an atom... released during a nuclear reaction.
Stored energy an object has because of its position or shape. ex. A car waiting at the top of a ramp (not moving).
Energy that is transmitted in the form of (electromagnetic) radiation. (light) ex. Solar energy
A resource that is naturally replaced in a relatively short time. ex. Sunlight, wind, trees, water, biomass, hydrogen, geothermal.
The internal energy of a substance due to the movement or vibration of its atoms or molecules. (heat)
To convert one form of energy to another. ex. A battery powering a flashlight converts chemical energy to radiant energy.
Process by which, in a fluid being heated, the warmer part of the mass will rise and the cooler portions will sink.
Form of heat transfer where heat energy is directly transferred between molecules through molecular collisions or direct contact.
Energy that is radiated or transmitted in the form of rays or waves or particles.
triple beam balance
tool used to measure mass
tool used to measure liquid volume; also used to measure the solid volume of an irregular object.
ruler or meter stick
tool used to measure length and regular volume of a solid objects
The measuring system based on the meter, liter and gram as the base units of length, volume and mass.
Pictures that warn about hazards: chemical, heat, electricity, or procedural. Ex. Clothing Protection Safety; Eye Safety, Chemical Safety, and Sharp Object Safety
An open cylindrical container with a pouring lip; used for mixing larger amounts of substances
