Warm-up 1/24/12 • Teach the Teacher: Who are you rooting for in the super bowl, or favorite sports team, or best party ordure. • Tell me two things that are important for learning?
Learning Target • Learning Target: Determine if an object is living based on characteristics of life • identify the components of an experiment • Apply the steps of the scientific method to an everyday problem
Safety Success Love and Belonging Freedom and Independence Fun and Enjoyment Valued Purpose The Six Keys for Human needs
What is science? • In latin= knowledge • In dictionary.com= systematic knowledgeofthephysicalormaterialworld gained through observation and experimentation. • Biology book= is a body of knowledge based on the study of nature
Science is… • Creative • Unbiased observations • Unbiased: free from prejudice or favoritism • Fact vs. opinion • Developing theories through experimentation (pseudoscience: astrology)
Science is...(continued) • Expanding scientific knowledge • Challenging accepted theories • Testing Claims • Undergoes peer review • Uses Latin and the Metric System
What is Biology? • In Greek= bio=life, logos=study • Book=science of life • Aka knowledge of life • From how life formed, studying diversity, how life continues, everything
What do Biologists do? • Study the diversity of life • Animal behavior • Ecologists • Research Disease • Develop Technologies • Technology=the application of scientific knowledge to solve human needs and to extend capabilities • Prosthetic legs, mechanical hearts, etc. • Improve agriculture • Preserve the environment
Trash Bball • Rules: 1. must pick up your own trash ball • 2. no throwing at other people unless I tell you can • 3. must make a certain number of baskets to win

Living or Nonliving? • DNA
To be alive these 8 characteristics must exist: • Made of one or more cells • Displays organization • Must have a form, can’t be like the wind • Grows and develops • Reproduces
Responds to stimuli • Stimuli= something causes a reaction • Requires energy • Maintains homeostasis • Adaptations evolve over time
Scientific Method • Ask a Question/determine a purpose • Comes from observing • Form a hypothesis=educated guess • Collect data
Control group=the group not receiving the factor being tested, nothing is done to this group • Independent variable=one part of an experiment that can change, determines the outcome • Dependent variable= factor being measured in a controlled experiment • Analyze the Data Graphs, tables, charts, etc. • Report Conclusion
Procedure • 1. Get into partners • 2. One person wears strings like handcuffs (horizontally). • 3. Other person wears hands cuffs, but vertically and sting is between the first person’s string and body • 4. Figure out how to untangle the string.
Intro Scientific Method String Lab • Identify the independent and dependent variables. • 2) What was the control used in your experiment? • 3) Give two examples of hypothesizes that could have been used to solve the problem.
