Properties of Life • 1. Cellular Organization – all living things show an orderly structure • Cell Tissue Organ Body System Organism http://www.google.com/imgres?q=cellular+organization&start=48&num=10&hl=en&client=safari&rls=en&biw=1302&bih=898&tbm=isch&tbnid=j0aySELoctAMNM:&imgrefurl=http://www.rci.rutgers.edu/~uzwiak/AnatPhys/APFallLect5a.html&docid=BaIdaJgB_Zx8VM&imgurl=http://www.rci.rutgers.edu/~uzwiak/AnatPhys/APFallLect5a_files/image001.jpg&w=640&h=480&ei=HugfT7KnOIObtwf-5sDPBQ&zoom=1&iact=rc&dur=462&sig=104895510269790948438&sqi=2&page=3&tbnh=168&tbnw=224&ndsp=26&ved=1t:429,r:21,s:48&tx=87&ty=66
Properties of Life • 2. Reproduction – all organisms have the ability to reproduce • How does an amoeba reproduce? http://www.tulane.edu/~wiser/protozoology/notes/images/ciliate.gif

Metabolism • Energy use for body/cell functions • Input of energy (food) output of heat or movement (Show Energy Ball) http://t2.gstatic.com/images?q=tbn:ANd9GcQFHkEyZ0yAoGwT-YTTX8BcP_fAfVDkuaMrHEowRIb-lQR7p9LVfQ http://t3.gstatic.com/images?q=tbn:ANd9GcQkgWl3-6zvrim2YaKsnUIhzdP6JKUU-2WJgBwM2ZF0SyJu1z-_6w
Properties of Life • 4. Homeostasis – maintenance of stable internal conditions in spite of changes in the external environment (text) • Making changes to survive (Nash) http://t0.gstatic.com/images?q=tbn:ANd9GcQMcHfDdi6rHq72gIjgzGOdg3wtxP9eGN9NnBD9w4URqtZQflsPiw http://t2.gstatic.com/images?q=tbn:ANd9GcSCWTTcpuU0vGvF7mFy-zdUDg0HFglPo_0R82LqBlMCmPTuNgnrjw
Properties of Life • 5. Heredity – the passing of traits from parents to offspring (Text) (Why you look like your parents (Nash)) • Gene – sets of inherited instructions for making proteins • Mutation – a change in the DNA of a gene http://t2.gstatic.com/images?q=tbn:ANd9GcRwHOJUeFB8XBH6Tg8njxrHIVGyStW4NDypBa5yex1PUK1VpPz8fQ http://t3.gstatic.com/images?q=tbn:ANd9GcQ-o29vNSxfdWyYcfjl9y1LUWUMIRgQj-eESB4oDWLQqbr5Y0w_
Properties of Life • 6. Responsiveness – response to the environment • Stimulus – triggers a response • Smell, sound, taste, touch • Response – reaction to a stimulus • Running from a diffusing smell http://t3.gstatic.com/images?q=tbn:ANd9GcQIuLHi8zihjwJi8xVmnKXeLSSZfdUiQXKquTF7ULQRCpacdRXx http://www.google.com/imgres?q=getting+bit&hl=en&client=safari&rls=en&biw=1302&bih=898&tbm=isch&tbnid=Z_bUfVfRes6flM:&imgrefurl=http://www.eurweb.com/2011/05/bedbugs-now-carrying-superbug-germs/&docid=DZjHIibRXrOz2M&imgurl=http://cdn.eurweb.com/wp-content/uploads/2011/05/bed_bug2011-med-wide.jpg&w=450&h=364&ei=G-ofT-2QKImCtgfO6p2rBQ&zoom=1&iact=rc&dur=276&sig=104895510269790948438&page=2&tbnh=159&tbnw=197&start=23&ndsp=25&ved=1t:429,r:5,s:23&tx=146&ty=50
Properties of Life • 7. Growth and development • All organisms get larger over time http://t3.gstatic.com/images?q=tbn:ANd9GcT6I-YraHSgv5RZ3nUlrWXQMWWj62pPlW0Yr6QRY44e_walkPgbnv6jL6nZ http://t1.gstatic.com/images?q=tbn:ANd9GcSVIRB8wIP64v2P8POhQn6Qf0iwFbT_2oeb0Ogrxl7dsstfSxRDvg
The Scientific Process • OBSERVATION, OBSERVATION . . . • 5 Steps to the Scientific Method • 1. Observation • 2. Forming Hypothesis • 3. Experiment (to test hypothesis) • 4. Collect Data • 5. Drawing Conclusion / Analyze
4. Data Collection / Analyze • Two Types of Data Collection • 1. Qualitative - observation • 2. Quantitative - measurement • Ex. Is my experiment Qualitative or Quantitative?
Is it bad if your hypothesis was not correct? • No • Accidental Discoveries • X-rays – late 19th c. German scientist putting things in front of radiation saw his bones on the wall • Penicillin – A. Flemin 1928 saw that mold had infected a petri dish of growing bacteria, and it was killing the bacteria • Artificial sweetner, during medical research, scientist did not wash their hands • Microwave ovens – 1946 a magnetron melted a candy bar in engineer P. Spencer’s pocket • Potatoe chips – 1853, Chef Crum customer complained about too thick so . . . • Accidental – careful • Bill Nye and accidents

Living in Harmony With Our Environment • World Surface Area 196,940,000 sq. mi • World population 6,730,000,000 • World Population Chart • Use of Rainforest • Deforestation (medicine, species, oxygen) • Groups to educate or stop this • Waste Production • Waste Composition • Trash Trivia
Living in Harmony Cont. • What can you do? • Reduce, Reuse, Recycle • (Does order matter activity) • Does order matter? ABSOLUTELY • (1) REDUSE (2) REUSE (3) RECYCLE • (See example glued to board)
Biology Can Bring the World Together • Can you name something that has brought multiple nations together for a positive effort? • Human Genome Project • Took 15 years, 1990-2005 • Map the entire human genome
