September 18, 2013 – Bell Work
• Sketch the map
1. Sketch the map
2. Copy the questions
3. Choose your answers
4. Explain each answer
characteristicsDefinition
• Collection of traits that form the way an organism looks
Facts/Examples/NonExample• We inherit our traits from
our parents• So do other organisms • 50% from each parent
organism• EX: hair color, body shape,
skin color• NONEX: acquired traits such
as playing a musical instrument
Memory Pictograph
chemical change
Definition• Change in a substance that
produces a new type of substance with new chemical properites
Facts/Examples/NonExample• Happens because of chemical
reactions• Chemical bonds are broken
and/ or new bonds are formed• Cannot be reversed – new
substances formed• EX: fire, rust, baking soda &
vinegar• NONEX: physical change such
as change in size by cutting paper or wood
Memory Pictograph
chemical weatheringDefinition
• Process by which rocks are broken down by chemical changes
Facts/Examples/NonExample• Man-made or natural• Dissolves rocks• Acids do most of the
weathering and erode the surface of the rocks
• EX: acid rain• NONEX: rocks eroded by
wind or frost action which are both mechanical weathering
Memory Pictograph
Acid rain
wears down
surface by
chemical
action
chlorophyll
Definition• Chemical that is used by plants
during photosynthesis
Facts/Examples/NonExample• Gives plants their green
color• In chloroplasts of plant cells• Allows plants to produce
their own food• EX: all plants • NONEX: animals do not
produce their own food
Memory Pictograph
chromosomeDefinition
• made of strands of DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms
Facts/Examples/NonExample• Humans have 46 chromosomes• 23 chromosomes from each
parent• “blueprint” of how to build (or
repair) a particular organism• EX: eukaryotes have
chromosomes in the nucleus of the cell
• NONEX: prokaryotes have DNA but not inside of a nucleus (prokaryotes do not have a nucleus)
Memory Pictograph
climax communityDefinition
• Last step of a natural process called succession
Facts/Examples/NonExample• Takes a long time• Lake dries up, becomes a
wetland, then a meadow, then shrubs, then trees then forest
• Can stay as a forest for many years
• EX: U of M Dearborn hiking area is a beech-maple climax community
• NONEX: people cut down all the trees and change natural pattern
Memory Pictograph
closed circuitDefinition
• Electrical circuit in which electricity can flow freely
Facts/Examples/NonExample• Wires are fully connected
into a path for electrons to flow freely
• Light bulbs can light up• Battery is source of electron
flow• EX: flashlight switched on• NONEX: open switch,
broken wire, or burned out light bulb
Memory Pictograph
cold bloodedDefinition
• Animal whose body temperature changes with the environmental temperature
Facts/Examples/NonExample• Body temperature is not
constant• Body temperature changes
with temperature of its environment
• Warm and cold extremes can kill the animal
• EX: reptiles, amphibians, fish, invertebrates
• NONEX: mammals, birds
Memory Pictograph
cold frontDefinition
• Occurs when cold air mass moves warm air mass upward
Facts/Examples/NonExample• Brings cold and unstable
weather• Can be fast or slow• Can form dangerous clouds
quickly and lead to severe weather
• EX: cumulonimbus clouds (tallest and possible tornado producers)
• NONEX: warm front – rain likely and less severe
Memory Pictograph
communityDefinition
• Group of different populations living in the same place
Facts/Examples/NonExample• Groups of organisms affect
each other in the community
• Creates a unique area• EX: forest community, pond
community, meadow community, coral reef community
• NONEX: population refers to just one species in a community
Memory Pictograph
competitionDefinition
• Interaction between 2 organisms over basic resources such as food, water, shelter, mates
Facts/Examples/NonExample• The more adaptations an
organisms has to its environment, the less it needs to compete
• Some animals change their habits to have less competition
• EX: invasive species outcompeting native species, deer feeding at different times or on different plants
• NONEX: mutualism
Memory Pictograph
compoundDefinition
• Pure substance made up of 2 or more different elements that are bonded together
Facts/Examples/NonExample• Have chemical and physical
properties not like the original elements
• Always has a chemical formula• EX: salt (NaCl), water (H2O),
carbon dioxide (CO2)• NONEX: elements are made of
just one type of atom, mixtures are made of different materials next to each other BUT NOT BONDED TOGETHER
