6 BiologyStudy of living thingsIncludes Zoology, Botany, Ecology, etc.
7 Physical Science Big Ideas Matter & ChangeForce & MotionEnergySpace & TimeConstantly change due to new discoveries and theories.
8 Technology Applied science - using knowledge Works with science Discoveries/advances in one lead to advances in otherEx: computerConsistently changing
9 Technology Examples Not just computers and phones Exs: chalkboard, plastics, glass
10 Theory Is a well tested explanation of observation or experiment Never proved, but facts support themExs: Kinetic theory, atomic theory, theory of evolution
11 Law Is a statement that summarizes a pattern in nature DOES NOT explain why (like theory)Exs: Newton’s Laws, Law of Gravity, Gas Laws
12 Scientific Models Is a representation of an object or event Used for things hard to observe directly (airplane, atom, cell)Can be mental, physical, graphic, simulation, drawing, analogy, or mathematical
13 Scientific Method It all starts with a question/curiosity Something you want to better understand or a problem you want to solve
14 Steps Observe Ask Question Hypothesis Test (experiment) Analyze data (conclusions)Revise, repeat, resolve
15 ObservationInformation you receive through your senses (i.e. smell, touch, etc.)Usually leads to the question you want answered
16 Hypothesis Proposed answer to question Usually research subject before making hypothesisHas to be testable
17 Experiments Use exp. to test hypotheses Variable - anything that can change during exp.
18 VariablesDependent variable - the variable that causes a change in another (usually done by you)Ex: TimeIndependent variable - the variable that changes because of manipulation (usually related to what you’re wanting to know)Ex: GrowthUse these to make controlled experiment
19 Conclusions Did you support or go against hypothesis? Support - test again and could lead to theoryReject - revise exp. and test again
