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

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

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

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

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

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

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

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)
