Sugar dissolving in water is this type of change.
What is a physical change?

These are the 6 forms of energy related to changes in matter that were discussed in class.
What is kinetic, potential, chemical, electromagnetic, electrical, and thermal energy?

This is why the mass of a candle does not disappear while burning
What is the law of conservation of mass states that no matter or mass can be destroyed during a chemical change, therefore the candle has simply changed forms
200
This is a single kind of matter that is pure, meaning it always has a specific makeup- or composition- and a specific set of properties.
What is a substance?
200
This is the formula for Volume.
What is length x width x height (l x w x h)?
200
This is the difference between a physical change and a chemical change.
What is a chemical change creates a new substance while a physical does not?
200
Visible light is an example of this kind of energy.
What is electromagnetic energy?
200
This is the difference between an element and a compound.
What is an element is a pure substance that cannot be broken down and a compound is two or more elements chemically combined that can be broken down.
300
This is what it is called when atoms combine to form larger particles (the same atom combining or two different atoms combining).
What is a molecule?
300
This is the formula for Density.
What is Mass/Volume?
300
This is the FULL definition of the law of conservation of mass.
What is the fact that matter cannot be created or destroyed in any chemical or physical reaction?
300
This is the type of energy of electrically charged particles moving from one place to another.
What is electrical energy?
300
This is one example of a mixture that is a solution and one example of a mixture that is not a solution.
Answers may vary:
Solution: Gatorade, salt water, sugar water, koolaid, air, etc
Not a solution: salad, dirt, cookie, concrete, pizza, etc
400
This is the kind of mixture you get when you mix sand, rocks, and water to make concrete.
What is a heterogeneous mixture?
400
This is the order (from bottom to top) that these liquids would separate because of their Density:
Water = 1 g/mL
Alcohol = 0.8 g/mL
Molasses = 1.4 g/mL
Motor Oil = 0.9 g/mL
What is Molasses, Water, Motor Oil, Alcohol?
400
This is the definition of energy.
What is the ability to do work or cause change?
400
As you push your bike up a hill and then ride it down, this is the 2 changes in energy that you would undergo.
What is potential to kinetic?
400
This is why weight is not considered a constant measurement of the amount of matter an object contains.
What is because gravity can change depending on where you go, but mass always stays the same.
500
This is the BOOK definition for an element.
What is a pure substance that cannot be broken down into any other substances by chemical or physical means?
500
These are the 3 common units of volume.
What is liter (L), milliliter (mL), and cubic centimeter (cm3)
500
Ice melting is an example of this kind of thermal change.
What is an endothermic change?
500
These are the two rules in regards to changes in energy during a chemical change.
What is during a chemical reaction, chemical energy may be changed to other forms of energy. Also, other forms of energy may be changed to chemical energy.

DAILY DOUBLE
Calculate the Density of the following items using the following volumes if they are all 10 grams in mass:
Alcohol: 12.7 cm3
Corn syrup: 7.25 cm3
Cooking oil: 10.8 cm3
Water: 10 cm3
Then label them from most dense to least dense using the correct labels for density.
What is corn syrup (1.8 g/cm3), water (1.0 g/cm3), cooking oil (0.93 g/cm3), and alcohol (0.79 g/cm3)
