Science / In Latin means to know or to discover / Based on Direct Observations and a Testable Hypothesis / Measureable / Not a ‘belief’ / In Latin means to know or to discover / Based on Direct Observations and a Testable Hypothesis / Measureable / Not a ‘belief’

3 major Themes / Evolution-life ‘evolves’ or changes over time / Information transfer- from within an organism, organism to organism and from the environment to an organism. / Energy transfer-continuous input of energy / Evolution-life ‘evolves’ or changes over time / Information transfer- from within an organism, organism to organism and from the environment to an organism. / Energy transfer-continuous input of energy

Living vs Nonliving Organisms…. / Are composed of cells / Grow and Develop / Perform and regulate chemical activities / Respond to stimuli / Reproduce / Evolve and adapt to the environment / Are composed of cells / Grow and Develop / Perform and regulate chemical activities / Respond to stimuli / Reproduce / Evolve and adapt to the environment

Systematics (study of diversity and relationships of organisms) * Domain / Kingdom / Phylum / Class / Order / Family / Genus / Species * Domain / Kingdom / Phylum / Class / Order / Family / Genus / Species
11
Domains / Eubacteria / Archaea / Eukarya - (Eukaryotes) / Eubacteria / Archaea / Eukarya - (Eukaryotes)
12
Kingdoms / Eubacteria - bacteria / Archaea - Archaebacteria / Eukarya - Animalia, Fungi, Plantae, Protista / Eubacteria - bacteria / Archaea - Archaebacteria / Eukarya - Animalia, Fungi, Plantae, Protista
13
Major Themes / Evolution - Populations will change ‘evolve’ over time / Information Transfer-cells must communicate with each other and from parent to offspring. / Energy For Life - continuous supply of energy / Evolution - Populations will change ‘evolve’ over time / Information Transfer-cells must communicate with each other and from parent to offspring. / Energy For Life - continuous supply of energy
14
Species evolve / Natural selection drives the evolution of organisms (finches, pests, superbugs) / Darwin’s Origin of Species in 1859 / Variations by mutations / New discoveries in genetics have given support to the evolution theory / Natural selection drives the evolution of organisms (finches, pests, superbugs) / Darwin’s Origin of Species in 1859 / Variations by mutations / New discoveries in genetics have given support to the evolution theory

Energy Pyramid / Producers / Consumers / Decomposers / Producers / Consumers / Decomposers
16
Energy Pyramid / Producers - Autotrophs - Photosynthesis / Consumers/Decomposers - Heterotrophs / Primary consumers - Herbivores / Secondary consumers - carnivores / Teritiary consumers - carnivores (What would a venus fly trap be???) / Producers - Autotrophs - Photosynthesis / Consumers/Decomposers - Heterotrophs / Primary consumers - Herbivores / Secondary consumers - carnivores / Teritiary consumers - carnivores (What would a venus fly trap be???)
17
Energy Pyramid / What supplies the initial energy? / Where is energy converted? / When/Where is energy lost? / What happens when an organisms dies? / What supplies the initial energy? / Where is energy converted? / When/Where is energy lost? / What happens when an organisms dies?
18
Scientific Method / Problem/Question / Research / Hypothesis / Experiment / Data Gathering and Analyzing / Conclusion / Problem/Question / Research / Hypothesis / Experiment / Data Gathering and Analyzing / Conclusion
19
Scientific Method cont. / After experiment is repeated, then publish findings and limitations. / Experiment and findings must be supported by others-Peer Review / After experiment is repeated, then publish findings and limitations. / Experiment and findings must be supported by others-Peer Review
20
Hypothesis / Two Types / Null Hypothesis / Directional Hypothesis / Two Types / Null Hypothesis / Directional Hypothesis
21
Hypotheses (see next slide first) Effect music has on the growth of plants. / Effect music has on a person’s ability to retain information while studying. / Effect music has on 17 year olds ability to retain information while studying. / Effect music has on 17 year old males ability to retain information while studying.

22
Experiment / Must include a control for comparison / Must be appropriate sample size / Must be repeatable / Two types of variables: / IV-independent variable / DV-dependent variable / Must include a control for comparison / Must be appropriate sample size / Must be repeatable / Two types of variables: / IV-independent variable / DV-dependent variable
23
Avoiding bias / Blind study / Double blind study / Blind study / Double blind study
24
Data / Must be recorded unbiased / Use standard deviation to determine if data from the variable is statistically different. / Must be recorded unbiased / Use standard deviation to determine if data from the variable is statistically different.
25
Conclusion / Not important if hypothesis is correct or not. / Information learned about the question is what is important!!! / Not important if hypothesis is correct or not. / Information learned about the question is what is important!!!
26
Science Theories The longer a theory exists in time and/or the more effort to prove it false the stronger the theory becomes.
