1 Biology- the Study Of Life Chapter 1, Section 3

2 Taking Notes Summarize! Duplicate important diagrams Center important headings on your page Write page numbers, if given in notes Listen for teacher’s cues (“hint, hint”)

3 Time Management Use your planner Find time each day to review your notes/do worksheets, etc Don’t procrastinate! If you don’t understand- ASK!!!

4 Study Habits STUDY!!!! Be prepared for class- pencil & notebook Make-up all missed work Review your notes before every test or quiz Study with Mozart (classical music) =)

5 Make your textbook work for you

6 Let’s begin...

7 What is it? Biology is the “study of life” –“Bio-” = life –“-logy” = study of Enormous scope –space –time

8 Understand… cell level

9 Understand individuals…. traits

10 Appreciate beauty…..

11 Appreciate… individuality

12 Understand we have things in common

13 Understand…... behavior

14 Understand…. Social skills

15 Understand……Systems

16 More pictures of systems….

17 Understand.. World … and World around us

18 "Those things are better which are perfected by nature than those which are finished by art." - Cicero, Roman Statesman

19 Biology is Changing & Developing Genetics and cell biology revolutionizing medicine & agriculture Molecular biology new tools to trace origins and dispersal of early humans. Ecology is helping evaluate environment Neuroscience & evolutionary biology reshape psychology and sociology

20 Since Biology is about life… what is Science? Science means “to know” in Latin Scientific Method specifies a process used to find answers there are many different approaches

21

22 Chapter1, Section 3, pg14-17 Scientific Process (a.k.a Method) –Make observations –Ask questions –Form hypothesis –Test hypothesis (retest, retest, retest) –Develop theory

23 No set/definite method Make observations Ask questions Form hypothesis –Make prediction Test hypothesis Develop theory

24

25 Problems scientists face Not being objective –Changing data Haeckel falsified drawings of embryos –Personal beliefs environmental movement –true science? –Conservation biology Extent of effort genetics of panther problem

26 Variables, pg 17 Key Terms I ndependent Variable- what “I” control to be different Dependent Variable- what is measured or recorded. My “data” Control- NO independent variable Standard- what is kept the same through the experiment

27 The Pea Story… Farmer Jon has 4 plots of land, 1 acre each. He wonders how the amount of fertilizer will affect the height of his pea plants. He puts no fertilizer on the first plot, 20 lbs on the second plot, 40 lbs on the third plot, and 60 lbs on the 4 th plot. And then he waits……

28 Lets Grow Peas… For all plots 1 acre garden Same amount of water Same amount of sunlight What was Different? Fertilizer amounts 20lbs of fertilizer 40lbs of fertilizer 60lbs of fertilizer No fertilizer 2in 6in10in18in The Farmer recorded Height of plants

29 Sooo…. For this project Independent Variable- amt of fertilizer Dependent Variable- height of plants Control- No fertilizer Standard(s)- size of plot, amt of water, amt of sunlight

30 Keys to a Good Graph Independent variable goes on X axis Dependent variable goes on Y axis Include your units Title

31 Practice Amt of fertilizer (lbs) Height of plants (in) Fertilizer affects Plant Height

32 Lets Try again… Scientists were studying two Florida sea turtle populations- one in New Smyrna Beach and one in Melbourne Beach. The scientists tracked the turtles and counted the number of eggs in each nest as the turtle laid them. Independent Variable?Dependent Variable?

33 Graphing Practice They found that, on average, nests on the Melbourne beaches contained 115 eggs and nests on the New Smyrna Beaches contained about 100 eggs. Location of nests Average number of eggs Title
