Flashcards in Class 2 Intro to science Teacher Notes Deck (19):
1

science

process of using reason, observation, experimentation to determine things about universe that can be verified as true by other independent observers

2

scienctifi cmethod

obsertvations, hypotheses, predictions, expxerimentation,

3

iterative process

experiment/observation leading to refining our hypotheses, new predictions, further testing

4

parsimony

prefer simplest explanation for set of observations

5

fact

understanding of natrual universe that has been well established by careful and repeated inquiry

6

provisional

accepted as true but w/knowledge that there may be additional evidence collected in future contradicting understanding

7

scientific theory

related set ofhypotheses that together form a broad ranginging, testable explanation about some fundamental aspect of natrue

8

inductive reasoning

bottom up - specific observations leading to general conclusions - logic flows from specific to general

9

deductive reasoning

top down - general premises to conclusions about specifics, logic flows from general to specific whereby basic premises about operation of universe allow you to reach new conclusions

10

levels of biological organization largest to smallest

biosphere, ecosystem, community, population, individual, organ sys, organ, tissue, cell, organelle, molecule

11

two views on hthe levels of biological orgnaizaiton heirachy

atomism/reductionism, emergence

12

atominism/reductionism

everything at higher levels can be understood by examining lower levels

13

emergence

this view puts forth that each higher level has properties not possessed by lower levels, emergent properties arise in two ways - interactions among parts of a level, aggregations have collective properties not posesed by lower levels

14

evolution is the _____

GUT - grand unifying theorem of biology - nothing in biology makes sense except in light of evolution

15

evolutionary process responsisble for both

unity of live, diversity of life

16

natural selection

causes adaptive evolutionary change

17

basics of natural selection

if there are hertiable variations among individuals in a population, these differenes ultimatly lead to differences among individuals in terms of how many ofspring each variant produces, there will necessarily be an increase in the frequency of the type that reproduces better

18

proximate level questions -

"how questions" - understanding mechanism underlying phenomen

19

ultimate level questions

why questions, questions aimed at understanding reproductive benefit of particular traits
