a variable that changes depending on some other factor; the variable that is the data we are measuring.

a variable that does not change for the duration of the experiment...it makes it "fair."

a statement that answers your question

scientific data to support the claim

ties together the claim and the evidence

anything that has mass and takes up space

properties that can be seen without changing the object, using your senses

a pure substance composed of 2 or more elements that are chemically combined; represented by chemical formulas, ie. H2O or NaCl

a change in which a new substance with different properties is formed/created

production of a gas, change in temperature, production of a solid precipitate, or change in color

the ability/inability to burn

the ability/inability to react with air, water, etc.

a change that affects one or more physical properties of the object but does NOT change the identity

an element that can be classified based on physical properties of hardness, luster, ease of malleability, conductivity, and ductility

an element that lacks most of the physical properties of metals

an element that has both metallic and nonmetallic properties

the ability to be pounded into thin sheets

the ability to be shattered and broken into pieces when pounded

the way matter reflects light from its surface, matter that reflects a large amount of light is shiny, and matter that reflects little light from its surface is dull

the ability to be pulled into thin wires

matter that allows electricity to flow through it

matter does not allow electricity to pass through easily

a naturally occurring solid, made up of elements

how well a substance will resist scratching by another substance; 1 being the softest to 10 being the hardest

a pure substance that is composed of the same type of matter throughout and cannot be divided into simpler substances through normal processes
