100
Anything that has mass and takes up space.
What is matter?
100

a characteristic of matter that can be observed or measured without changing the identity of the matter

What is a physical property

100

a change in size, shape, form, or state in which the matter's identity stays the same.

What is a physical change

100

a change in which substances change into other substances with new physical and chemical properties

What is a chemical change?

100

This is equal to the number of protons each element has

What is the atomic number?

200

a small particle that is the building block of all matter.

What is an atom

200
This is the formula for density.
What is D=M/V?
200

This is when matter skips from a state of gas to a solid without becoming a liquid

What is deposition?

200

5 chemical properties

reactivity, oxidation, flammability, acidity, toxicity

200
These are three ways to increase the rate of a chemical reaction.
What are to increase the: temperature, concentration, or surface area?
300

The number of these always differs in atoms of different elements; their number is unique to each element

What are protons?

300

Name 5 physical properties of matter

mass, volume, density, conductivity, boiling and melting point, solubility, magnetism, ductility, malleability, viscosity, luster, color, taste, odor

300

This happens to the particles of a substance when thermal energy is added .

What is the particles get excited and start to move faster and farther apart, their attraction begins to weaken?

300

These are the 4 signs of a chemical change discussed in class.

What are bubbles, odor change, color change, formation of gas or solid that is not a state change, and energy or temperature change?

300

These are examples of one: element, compound, and mixture.

What are... carbon, H2O, and pizza?

400

This is the chemical formula for a compound with 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms.

What is C6H12O6 (glucose, a product of photosynthesis)

400

This is a physical property that usually can't be used to separate mixtures, but will tell us if it is electrical in nature.

What is conductivity?

400

This substance undergoes sublimation in fog machines on Halloween

What is CO2 (dry ice)

400

This is the definition of "concentration."

What is "the amount of a substance in a certain volume"?

400

These are two size-dependent physical properties.

What are mass and volume?

500
This is the difference between a heterogenous mixture and a homogenous mixture.
What is that a heterogenous mixture is unevenly mixed, while a homogenous mixture has different substances that can't be seen by the naked eye.
500
These are two size-independent properties of a matter.
What are density and melting point?
500

This law was used to "check our work" in the Oreo cookie lab and will be revisited when we talk about balancing chemical equations.

What is the Law of Conservation of Mass: "Matter is neither created nor destroyed"?

500

This is the balanced chemical equation for creation of carbohydrates from carbon dioxide and water during photosynthesis.

What is 6CO2 + 6H2O -> C6H12O6 + 6H2O?

500
This is a way to separate a mixture of sand, sugar, and water.
What is to filter the sand from the sugar/water mixture then to boil the mixture and leave the sugar behind?
