GradingI believe that your grade should not depend on how bright the members of your class are, or
how hard they work in the course. I am using my professional judgment to set the standards that must be met: the class itself should not set the standards. Your grade should reflect your performance, no one else‛s, with respect to the subject matter in biology. If you are in a class with high achievers, you should not suffer for it. Nor should you profit by finding yourself among classmates that are poorly prepared or choose not to do the work. I do not want you to feel that you are competing with your classmates, but yourself. Learning should be cooperative, at least part of the time. I do not want to discourage you from helping each other, not copying or giving someone the answers but actually helping your classmates by forming study groups. I use the grading scale listed below. With this scale, the student will be able to calculate how he or she did on each test, assignment, quiz, or project.

Chapter 1 The Science of Biology
1.1 What is Science
Inquiry ActivityPage 2Follow directions
Once your groups are finished. Answer questions in the "ThinkAbout It" and be prepared to have a discussion about the activity
What you should have learned???1. Be more precise, exact, or specific.2. Writing procedures that can be replicated allows other
scientists to repeat the experiment to see if the same results occur every time.
ObjectivesExplain what is the goal of science?Explain what is a hypothesis?
Look at these pictures below, write 5 questions a biologist might ask about these picture.
ScienceAccording to your book it is an organized way of using evidence to learn about the natural world. Looking for patterns and connections that occur between events.
What else is science?Observing the natural worldCollecting data???
Goal of Science?The goal of science is to investigate and understand the naturalworld, to explain events in the natural world and to use those explanations to make useful predictions.
Science SkillsSmall groups
Without using any scientific thinking, be creative and explain why it rains.
clouds are cryingriver in the sky
Now, suppose someone does not believe your explanation. Could you supply evidence to support your explanation?
probably not, Why not???
There is no way to gather evidence, there is no way to observea cloud that is "crying"
Remember that scientists propose explanations that can betested by examining evidence.
Scientists use a method to get a problem solved.
Scientific Method
1. Problem/Questionwritten in question formwhat are you trying to solve
2. Research/ObservationsQuantitative uses numbers or measurements to collect dataQualitative does NOT use numbers or measurements in dataData information collected from the observations
used to make inferences logical interpretations based on knowledge or experiences, an explanation to your data
3. Hypothesisproposed answer to our questionmust be testablescientists develop hypotheses from prior knowledge,
inferences, and even imaginations4. Procedures
Step by step directions5. Experiment
Carry out your procedures6. Observations/Record
What did you see?What happened?Record data make data table, graphs, charts
7. Analyze/InterpretWhat is your data telling you?
8. ConclusionAccept or reject your hypothesis
How do they decide? Scientists accept or reject a hypothesis by evaluating the outcome of a controlledexperiment or by gathering more data
Include data and research in conclusion
Look at Figure 15 on page 6What are some other questions that might be asked about this discovery?
Male or Female?How did the person die?How old was the person?Where might the person have been going at the time that
he or she died?
How could we find the answers to these questions?Xray, dissecting the body
Scientistsskeptics question ideas and hypotheses
12 How Scientists Work
They follow the Scientific Method
Biologists questioned "life".
About 400 years ago, it was believed that dead things could produce living things.
What does generate mean?to bring into existence
What does spontaneous mean?without preparation, just happens
Spontaneous Generationnonliving produced living things
for example:maggots from meatmice from grainbeetles from dung
Scientists tested these beliefs by using the Scientific Method
Refer to Figure 18 page 9 and Figure 110 page 11.
What do these experiments suggest?Their Hypotheses
Redi tested maggots on meat, flies produce maggots
Spallanzani boiling would kill all living things
Results????the jar with flies produced maggots, the other did not
the opened jar had microorganisms in gravy
Each experiment contained variables:Controlled Variable/Variables
all components of experiments are kept the same
Manipulated Variablecomponent being tested, variable changed in experiment
Responding Variableresults, what happened in response to the changed variable
Controlled Experimentall variables remain the same in the experiment except for one
Theorydeveloped after evidence has been collected from numerous experiments
allows scientists to make proper hypotheses when conducting experiments
no theory is considered the only truth

13 Studying Life
Key Concepts1. What are some characteristics of living things?2. How can life be studied at different levels?
Compare the two objects and note similarities and differences between them.
Collaborate your findings and develop a paragraph of what makes one object a living thing and the other object not.
Clock Animal
This is what our year is going to cover...Living things in a variety of ways.
Biologystudy of living things
bio = livinglogy = study of
Characteristics living things share:
******KNOW ALL OF THESE******
1. Living things are made up of units called cells.Cell is the smallest unit of an organism that is consideredalive.
2. Living things reproduce.Sexual Reproduction cells from two different parents uniteAsexual Reproduction single parent produces offspring
identical to itself3. Living things are based on a universal genetic code.
Genetic Code written in a molecule called DNA4. Living things grow and develop.
Have a pattern of growth, division of cells, undergo differentiation to perform different functions
5. Living things obtain and use materials and energy.All animals must take in food for energy. The animalbreaks down or builds up material is called metabolism.Plants produce food through photosynthesis.
6. Living things respond to their environment.An organism responds to a stimulus.
7. Living things maintain a stable internal environment.The process of homeostasis maintains a constant internal conditions.
8. Living things change over time.Basic traits do not change, but over time organisms evolve or change
Look at figure 115 page 1617 You do not need to copy this.
Look at the bear and the salamander.What characteristics of life do both of these organisms exhibit?
all eight characteristics
How are these two living things similar, and how are they different?
both animals, living traits
different structure, size, habitat and many other ways
How does the salamander obtain the energy it needs to live?eats other organisms
Where do the redwoods and other plants obtain the energythey need to live?
photosynthesis
All starts with the sun for both animals and plants.
What about growth in living and nonliving things???growth of a child vs. growth heap
both grow but a child will develop and become "organized"
Do organisms always grow and develop at the same rate?no
When do organisms stop growing and developing?The process goes on at different rates but does not completely stop until death.
Branches of Biology20 questionsgold fish
During this little game, you conducted an investigation just likescientists do.You were presented with a problem and you needed to ask questions (the right questions) to reach the solution.In most cases the answers were available, sometimes they were not. As a scientist, figuring out the questions to ask is the mostdifficult part in the investigation.Different branches of biology ask different questions.Look at Figure 119 page 21
Levels of OrganizationMolecules, cells, groups of cells tissues, organs, and organ systems, organism, population, community,ecosystem, biosphere circle of life

14 Tool and Procedures
Key Concepts1. What measurement system do most scientists use?2. How are light microscopes and electron microscopes similar? How are they different?
Metric Systemused by scientists to collect data
use ladder on wall
Refer to page 24 for Common Metric Units
Practice1 kilometer = meters130 meters = kilometer5000 milligrams = grams.45 liter = milliliters2500 milliliters = liters0.017 grams = milligrams3.5 metric tons = kilograms2.8 liters = cubic centimeters30,000 milliliters = cubic centimeters
Microscopes Appendix D (page 1070 1071) picture and techniquesLight microscopes
produce images that are magnified by focusing light rays
