10 AP Biology Lab Safety Tour  Questions?

11 AP Biology The Scientific Method & Experimental Design

12 AP Biology What is Inquiry?  Begins with observations you make about the natural world, followed by a question.  What is causing that?  Use a variety of methods to answer the questions you raise  Lab & field investigations, models, simulations, data sets  Scientific method of investigation is cyclic, not linear…why?

13 AP Biology The Scientific Method: 1. Make Observation 2. Statement of problem, ask a question 3. Hypothesis: propose a tentative answer 4. Design & conduct an experiment (Use quantifiable data  math is extremely important) 5. Use statistical tests to evaluate the significance of your results (Χ 2 test, null hypothesis) 6. Acceptance or rejection of hypothesis.

14 AP Biology

15 Data  Are recorded observations  Can be quantitative or qualitative Figure 1.24

16 AP Biology The Role of Hypotheses in Inquiry  In science, a hypothesis  Is a tentative answer to a well-framed question, an explanation on trial  Makes predictions that can be tested

17 AP Biology  We all use hypotheses in solving everyday problems Observations Questions Hypothesis # 1: Dead batteries Hypothesis # 2: Burnt-out bulb Prediction: Replacing batteries will fix problem Prediction: Replacing bulb will fix problem Test prediction Test does not falsify hypothesis Test prediction Test falsifies hypothesis Figure 1.25

18 AP Biology A Closer Look at Hypotheses in Scientific Inquiry  A scientific hypothesis must have two important qualities  It must be testable  It must have the potential of being rejected "No amount of experimentation can ever prove me right, one single experiment can prove me wrong." --- Albert Einstein.

19 AP Biology Designing Controlled Experiments  In controlled experiments we start with two (or more) groups that are as similar as possible and we devise a method to manipulate only ONE variable.  Independent Variable =the variable that is manipulated  Dependent Variable = the response that is measured

20 AP Biology Null Hypothesis  The premise that any observed differences are simply the result of random differences  When quantified observations, or data, are collected, statistical methods are used to calculate the likelihood that the null hypothesis is correct.

21 AP Biology Designing a Controlled Experiment  Labs, Inquiry, and Lab Reports are a HUGE part of AP Biology  You may work with ONE partner in this activity to review the components of a controlled activity. Each student must complete their own booklet.  At the end, you will practice designing your own controlled experiment.  You will have some class time today and tomorrow, Due Thursday!

22 AP Biology 8/27/13 HOMEWORK  Read through the following Biology Review PowerPoint.  Make sure that you remember/understand EVERYTHING  If not, be prepared to ask questions tomorrow!  This material will be covered on your first quiz!

23 AP Biology Study of Life Themes

24 AP Biology Themes  Science as a process of inquiry  questioning & investigation  Evolution  Energy transfer  Continuity & Change  Relationship of structure to function  Regulation  Interdependence in nature  Science, technology & society

25 AP Biology Science as a process of inquiry

26 AP Biology Science as a process of inquiry  Built on repeatable observations & testable, falsifiable hypotheses

27 AP Biology Falsifiable  A hypothesis is falsifiable if you can design and perform and experiment to show you that it is wrong, if it is wrong (meaning, it can be tested).  EXAMPLES:  Falsifiable – Increasing the amount of water given to a plant will increase its growth  NOT Falsifiable –  Giving a plant more water will make it happier.

28 AP Biology Evolution  Core theme of biology Charles Darwin

29 AP Biology Natural selection  Evolutionary change is a product of the process of natural selection Organisms don’t adapt; Organisms have adaptations.

30 AP Biology "Nothing in biology makes sense except in the light of evolution." -- Theodosius Dobzhansky March 1973 Geneticist, Columbia University ( )

31 AP Biology Evolution explains unity & diversity  Unity  what do organisms have in common & why do similarities exist?  common biochemistry & physiology  evolutionary relationships  connected through common ancestor  Diversity  but why are there differences?  natural selection  adaptations allow different individuals to survive in different environments

32 AP Biology

33 Organizing systems  Making sense out of the diversity  Hierarchical scheme Eastern gray squirrel Sciurus carolinensis

34 AP Biology 3 Domains of Life Bacteria, Archaea, Eukarya EukaryaBacteriaArchaea

35 AP Biology Energy transfer  Life is an open system  need input of energy  energy flows through  energy comes in, energy goes out  need a constant input  need input of materials  nutrients are recycled around & around ENTROPY RULES! DECOMPOSERS RULE, too! nutrients

36 AP Biology Energy utilization You think they’re eating… They’re harvesting energy!

37 AP Biology Continuity & change  Continuity of life is based on heritable information in the form of DNA  DNA – the genetic material – carries biological information from one generation to the next You can make more, a lot like you! TRAITTRAIT

38 AP Biology Structure and function  The alignment of structure & function is seen at all levels of biology organism cell organelle organ

39 AP Biology Regulation  Organisms need to maintain a “steady state” in the face of changing conditions  Homeostasis  achieve this through feedback  monitor the body like a thermostat  turn on when it’s needed, off when its not

40 AP Biology Interdependence in Nature  No organism is an island standing alone  communities, ecosystems

41 AP Biology Science, technology & society  Science & technology must function within the rules of society  ethics

42 AP Biology Themes  Science as a process of inquiry  questioning & investigation  Evolution  Energy transfer  Continuity & Change  Relationship of structure to function  Regulation  Interdependence in nature  Science, technology & society

43 AP Biology Why study themes of Biology?  Biology is an ever expanding body of knowledge  too much to memorize it all  need to generalize  create a framework upon which to organize new knowledge  themes are the key to understanding the nature of living organisms

44 AP Biology Homework  Be sure to write down any questions you may have and bring to class tomorrow!

45 AP Biology Agenda: Wed 8/28/13  Collect any signature pages  Review Data collection & Graphing  Homework – Finish Designing a Controlled Experiment  DUE TOMORROW! ***Quiz 1 will be next WEDNESDAY (9/4/13)  Covers review materials: Study of Life Review, Lab Safety, Scientific Method, Designing a Controlled Experiment/Experimental Design

46 AP Biology Data Tables & Graphing Review

47 AP Biology Working with DATA  When you work with data during an experiment, you need to:  Make accurate and precise measurements.  Account for error in measured values  Develop techniques and consistency for collecting data  Understand the units and properties of the data.  Make observations of trends and patterns in the data.  Produce visual representation of data, GRAPHS and CHARTS.

48 AP Biology Working with Data Continued  When you work with data during an experiment, you need to:  Use mathematical equations to model data.  Use mathematical models to make predictions of trends.  Test the fitness of models using statistical tests.

49 AP Biology What type of graph is best/most commonly used in scientific research?  LINE GRAPH!!!!

50 AP Biology Introduction to Graphing Techniques

51 AP Biology Introduction to Graphing Techniques  Identify the independent and dependent variable.  The independent variable is carefully controlled and varied by a specific amount during an experiment. It is plotted on the x-axis.  The dependent variable must be measured every time the independent variable is changed during the experiment. It is plotted on the y-axis.  Choose your scale carefully (must be consistent intervals). Make your graph as large as possible by spreading out the data on each axis. Let each square grid on your axis represent a convenient interval. Do not number every grid on your axis.  Plot each point as a dark dot

52 AP Biology Intro to Graphing Techniques cont.  Label each axis with the name of the variable and the units of measure. Using a ruler, darken the lines representing the axis.  Use a pencil and a ruler when drawing the axis for your graph.  Title your graph. The title should be short and clearly state the purpose of the graph. The title could include the independent and dependent variables. General the titles are written as the y variable vs. the x variable.  Use a single sheet of graph paper for each graph. Do not use the back of a sheet graph paper.  If you have more than one graph, number each graph in the upper right-hand corner.

53 AP Biology Introduction to Graphing Techniques

54 AP Biology Introduction to Graphing Techniques  Examine the position of your data points. Observe the pattern the data forms on the graph.  From the pattern the data makes on the graph, determine the type of relationship between the x and y variables.  Most times it will be best to use a smooth continuous line called a “ best fit ” line.

55 AP Biology Drawing a “best fit” line.  Your line should go through as many of the data points as possible. Use a ruler (if the line appears straight) and a sharp pencil to draw a best fit line.  When you draw your “best fit” line and the data points do not all fit on the line, draw the line so that there are equal numbers of data points above and below the line you draw. Try to draw the line so that it comes as close to all data points as possible.  This may result in a line that curves!  If it is logical for the data to go through the origin, take your best fit line all the way to the origin.  Draw your best fit line so that it goes a little past your last data point.
