1. Blue Answer Key Volume: the amount of space something takes up
Density: how much matter is in a given volume
Weight: mass x gravity
Mass: how much matter is in an object
Length: meter
Mass: kg ; g
D= mass / volume
Largest to smallest: kilo, hecta, deka, unit, deci, centi, mili
Law: says what is ( things fall down = gravity )
Theory: why it is ( land moves because of sea floor spreading)
Hypothesis: an educated guess about a specific observation

2. Red Answer Key
element
row: same number of levels of electrons (first row has one level ect)
Column: number of valence electrons
Atom: smallest part of an element
Because it has an equal number of protons and electrons
Metals: left side Non metals: right side
Protons Electrons Neutrons- neutral
The electrons in the outer most energy level
Number of protons

3. Green Key Ion: charged particle
Positive ions are formed when you loose electrons.
Negative ions are formed when you gain electrons
Covalent bond: bonding between two non metals, formed by sharing electrons
Ionic bonds: a metal and a non metal and are formed by the metal giving the non metal electrons 2
To multiply the entire compound or element by that number
Little number, tells you how many atoms of that element there are

4. Yellow Key Hard, green: physical flammable: chemical
Hard, particles close together
The resistance of a liquid to flowing
Particles are spread out, move faster, take on the shape of container, no set volume or shape
Ionized gas ( charged particles) found in stars and lightening
Vapor: going from a liquid to a gas ; Conden: gas to a liquid
Its more dense
Solute ( salt) Solvent ( water)
Chemical: changes the bonds and makes a new substance.
Physical change: doesn’t do that - it changes the form of the substance but not its chemical composition

5. Black Key
The joining of atoms ( hydrogen fuses together to make helium)
The amount of work that can be done
KE= 1/2 m v squared
Kinetic: motion Potential: Stored
Radio, Micro, Inferred, Visible, Ultra Violet, gamma
Position and mass
A human riding a bike and getting sweaty from it (answers can vary)
Battery to a light ( answers can vary)
E= mc squared
Potential
Kinetic
Hot to cold
Conduction – direct contact Radiation- travels in waves Convection- current
Conductor – lets energy go through Insulator- keeps energy in

6. Pink Key Electric field
Voltage: the pressure from the power source that pushes the current
Amps
Ohms
Volts
Stationary electric charge; created by friction
How many coils there are, the size of the solenoid, different size battery
Series all the lights will go out if one goes out, and only one path, if you add a light to a series it will decrease the other lights
Parallel lights will stay on, two path ways, lights stay the same level of brightness

7. Brown Given speed in a certain direction Distance / time
When speed is maintained
Steady straight incline
Change in velocity
No, your direction and speed don’t change
Distance and mass
1. an object in motion will stay in motion unless acted upon by an outside force 2. Force = mass x acceleration 3. For every action there is an equal and opposite reaction
9. Weight = mass x gravity

8. Purple Key
Mechanical waves have to have a medium to go through ( sound)
The substance in which a wave travels through
Wave vibrating in the direction of the source ( slinky)
Compression the closer together part of a longitudinal wave, rarefaction is the spread out part of L wave
Wavelength is the measurement from crest to crest or trough to trough it is inverse to frequency ( wavelength long frequency is short)
Hertz
The light bends as it enters a different medium
Volume
Decibels
The color that the object reflects ( absorbs all the other ones)
