1. Begin with a problem or question.2. Learn and collect information about
your question.3. Make a hypothesis: an educated guess about what might
happen; must be able to be tested; not just an opinion.4. Design and conduct an experiment to test your hypothesis.

Organisra= a living thing (plant or animal)Needs: organism's requirements to survive (like food, water,living space); organisms depend on other organisms and theirhabitat to meet their needs (birds use twigs to build nests)Competition: a struggle for a limited amount of resources; anorganism must have a way to get what it needs (food, water,oxygen) or it will die (plants in a jungle compete for sunlight)Ecosystem: the mix of all living (biotic) and nonliving (abiotic)things and conditions in an area (like temperature, animals, etc.)Environment: surrounding conditions; different environmentssupport different types of organismsSpecies= organisms with similar characteristics, live in samearea, and breed with each other (Monarch butterfly) to producefertile offspring; may naturally live (native) or not naturally live(invasive) in ecosystemPopulation: organisms that are of same species, live in samearea, and breed with each other (Monarch butterflies in acertain forest)Community: all the populations that live and interact in anarea (all the animals and plants that live in a certain forest)Habitat: area an organism lives in and gets what it needs (lake)Niche: the role a species has in an ecosystem (squirrelsconsume acorns from trees)Ecological Succession: gradual replacement ofplants and animals over time due to environmentalchanges (new species of trees replace the old treesthat burned down in a forest fire)

Parasitism good (+) bad (-)Mutualism good (+) good (+)Commensalism good (+) no effect
Traits: an organism's characteristics (eye color, height)inherited Trait: characteristic passed from parent to offspringthrough genesAdaptation: trait that helps an organism live and meet itsneeds better; organisms may use colors, smells, or poisons toblend into their habitat or protect themselves
Example: The bad scent of a skunk's spray helps tokeep predators away from it.
Natural Selection: process by which organisms with certainfavorable traits survive and reproduce more successfully thanothersEvolution= changing of a species' traits over many yearsBehavior: the way an organism does something or actsinherited Behavior: behavior an organism is born with; notlearned Example: breathingLearned Behavior: behavior an organism is not born with;must be learned Example: reading

Extinct: if a species cannot get what it needs, it will die out(T. rex dinosaur)Endangered= if a species cannot get what it needs, thenumber will get smaller and over time may become extinctImpacts on Organisra Populations: effects on populationscaused by the amount of food, water, disease, predators, etc.Human impact: humans can change an ecosystem in badways (like through air/water pollution) or in good ways (likeconservation); impacts can be short or long termEnvironraental Changes= changes in the environment canaffect the survival of an organism or species
Example= If a river dries up, the fish will die andthe food supply for bears will decrease. The bearpopulation will decline unless the bears find adifferent food source.
Limiting Factors: factors that control a population's size
Examples: food, water, living space, shelter
Carrying Capacity= maximum population that can live in anarea over a long period of time (controlled by limiting factors)
During photosynthesis, plants transform the Sun's energy (light)into chemical energy in the form of glucose. Animals eat plants(or other animals that have eaten plants) and use the glucose.Carbon Dioxide=Oxygen Cycle: during photosynthesisplants produce the oxygen that animals need; duringrespiration animals produce the carbon dioxide that plantsneed

Nitrogen is needed by living things. Bacteria change thenitrogen in the air into a form that plants can get and use fromthe soil. Animals get nitrogen by eating plants. Decomposersreturn nitrogen from dead plants and animals back to the soil.
Cell= smallest unit of living things- all organisms are made of one or more cells- cells have functions (jobs) that help keep the organism alive- cells contain smaller structures that each have a function
(_cell walls and chloroplasts are structures unique to plant cells)Nucleus: the "brain" of the cell; controls the cell's activitiesand contains chromosomes made of DNAStructure and Function-" the structure (overall makeup of anorganism or a part of it) can help with its function (job)Example: cell membranes are made of layers of fat and proteinwith small pores (structure) which allow the membranes tocontrol what enters and leaves the cells (function)
Diffasion: movement of molecules from area of hiÿherconcentration (amount) to lower concentrationOsmosis: movement of water from areas ofconcentration to lower concentration until cell equilibrium(stability) is reached; the cell membrane (outer layer) controlsthe flow of molecules in and out of the cellTurgor Pressure." pressure inside a plant cell caused by theosmotic flow of water into the cell; allows plants to remainupright; without turgor pressure the leaves would sag or wilt
Homeostasis: ability of an organism or its systems to maintaininternal equilibrium (stability or balance) using chemicalreactions and physical processes (feedback mechanisms)Feedback Response to Stimulus ExampleNegative decreases effect a body that is too hot,
will try to cool itself downPositive increases effect presence of stomach acid
increases its production
Example: Homeostasis - Body Temperature Control
Body Temperature Feedback Mechanism
Too hot sweat, blood vessels dilate(get bigger) to allow heat out
Too cold shiver, blood vessels constrict(get smaller) to keep heat in
Body Systems Work Together to Control Temperaturebrain detects body temperature is too low ÿ
\nervous system sends signals
/ \dermal (skin) blood vessels muscles contract

Living things build and organize themselves from small andsimple (atom) to complex systems (communities).

Atoms are the very small substances (building blocks) ofall matter. The nucleus is the central part of the atom andcontains most of its mass. An atom has three main parts.

(/ (ÿÿ around the nucleus\ "-ÿ J-'--protons (2)
neutrons (2)
Examples: methane (CH4) is made of 1 carbon and 4hydrogen atoms; ozone (03) is made of 3 oxygen atoms
Oeÿpound: substance made of two or more elements
Example: salt (NaCI) is made of sodium and chlorine
ixtÿre: two or more substances blended together;because they do not make a new substance, they keeptheir own physical properties; can be separated

Example: Water's specific heat is about five times greaterthan land's specific heat. Large bodies of water, likeoceans, store large amounts of heat from the Sun. Sincewater heats and cools more slowly than landmasses,temperature differences can cause thermal wind systems(cool air replaces warmer air).
Sea Breeze: daytime wind from ocean to landLaÿd Breeze: nighttime wind from land to ocean
