Final Exam Review Key
Metals, Non-metals, Metalloids, Elements, and Compounds
1. What is the difference between malleability, ductility, and conductivity?
Ductile (most metals can be drawn out into thin wires)
Malleable (most metals can be hammered into thin sheets)
Conductivity (the ability to conduct or transmit heat, electricity, or sound)
2. How can you tell the difference between an element and a compound?
Elements are pure substances that cannot be broken down into any simpler
substance. A compound is 2 or more elements that are chemically combined.
3. Salt or NaCl, is an atom, element or a compound? How can you tell?
Compound- Na (Sodium) and Cl (Chlorine) are chemically combined.
4. What is the most abundant element in the Earth’s crust?
Oxygen
5. What is the most abundant element in the Earth’s atmosphere?
Nitrogen
Energy
1. Describe the potential and kinetic energy in a roller coaster.
2. Create a flow map that shows the energy transformation in a flashlight.
Chemical
Electrical
Light
3. Draw a picture to represent each of the following: conduction, convection and
radiation. See conduction, convection, and radiation ppt. on netschool.
4. Draw pictures to represent an object being pushed on by balanced and
unbalanced forces.
Rock Cycle, Plate Tectonics, and Density
1. Draw the 3 types of plate movements and geologic events that occur at each.
(Divergent, Convergent and Transform)
DIVERGENT (SEA-FLOOR SPREADING): PLATES ARE MOVING APART. AT
DIVERGENT BOUNDARIES RIFT VALLEYS AND MID-OCEAN RIDGES FORM..
CONVERGENT: PLATES ARE MOVING TOWARD EACH OTHER. MOUNTAINS AND
VOLCANOS CAN FORM.
TRANSFORM: THEY ARE SLIDING PAST EACH OTHER. THEY CREATE FAULTS
AND EARTHQUAKES.
2. Draw the pie slice model of the Earth’s layers and label each layer:
(Crust, Lithosphere, Asthenosphere, Mantle, Outer Core and Inner Core.)
3. Draw and label the major tectonic plates.
4. What is the density of a rock that has a mass of 10 g and a volume of 5 mL?
Density=Mass/Volume
10/5 = 2 g/mL
Force and Motion
1. Circle the ramp that requires the least amount of energy to move the piano.
2. Draw a distance-time graph to represent something moving fast, slowing
down, and stopped.
See Motion Graph ppt. on netschool.
3. Calculate the speeds of cars C and D.
Speed = Distance/Time
Car C - 60/2 = 30 km/h
Car D - 120/2 = 60 km/h
Space
1. What force keeps planets orbiting the Suns and moons orbiting planets?
Gravity
2. List the inner (rocky) planets and list the outer (gas giants) planets.
Inner (Rocky) Planets: Mercury, Venus, Earth, Mars
Outer (Gas Giants): Jupiter, Saturn, Uranus, Neptune
Life
1. Describe the 3 domains and what kind of organisms would be found in each?
Eukarya: have a nucleus (eukaryotic), most are multicellular, can be
autotropic or heterotrophic
Archaea: don’t have a nucleus (prokaryotic), live in extreme habitats,
reproduce asexually, unicellular
Bacteria: don’t have a nucleus (prokaryotic), can be found anywhere,
reproduce asexually, unicellular
2. What is the difference between an autotroph and a heterotroph?
Autotroph: organisms that make their own food or producers
Examples: Algea, Plants, Trees, Shrubs
Heterotroph: organisms that feed off of or consume other things for energy
Examples: Humans, Animals, Most Bacteria, and Fungi
3. What is the difference between asexual and sexual reproduction?
Sexual Reproduction: Two organisms unite and there is an exchange of DNA.
The offspring will share traits of both parents.
Asexual Reproduction: Reproduction that occurs without an exchange of DNA
from two organisms such as binary fission or budding.
4. List the 4 Kingdoms of the Domain Eukarya, and state if the majority of
organisms in that kingdom are prokaryote or eukaryote, heterotrophs or
autotrophs, unicellular or multi-cellular. Give 3 examples of organisms that
belong in that kingdom.
Characteristics of the KINGDOM PLANTAE:
Multicellular, do not move, autotrophic (make their own food),
complex, cell walls in their cells
Examples of Organisms in this KINGDOM:
Multicellular algae, mosses, ferns, flowering plants, trees
Characteristics of the KINGDOM ANIMALIA:
Multicellular, move, heterotrophic (eat their food), complex
Examples of Organisms in this KINGDOM:
Sponge, jellyfish, humans, insect, fish, frog, bird
Characteristics of the KINGDOM PROTISTA:
Unicellular and Multicellular, can make their own food (autotroph) or
eat their food (heterotroph), most live in water (in moist areas like
soil or bodies), oldest Eukaryotic organisms
Examples of Organisms in this KINGDOM:
Amoeba, Diatoms, Euglena, Paramecium, some algae (unicellular)
Characteristics of the KINGDOM FUNGI:
Multicellular, most do not move, hetertrophic (food is digested outside
the “body” of the fungus)
Examples of Organisms in this KINGDOM:
Mushroom, mold, puggball, bracket fungus, yeast
