Lecture Text: Asking About Life 3 rd edition Tobin and Dusheck

Cramming is a sure path to failure ! Read ahead Attend class and pay attention!! Review within 24 hours Study a little at a time Study often “Do something” with the material : make flashcards, draw diagrams, make up songs.

Come out of your shell and ask questions!

“Ferret” out the information to the study guide.

Find a “Study Buddy” !

Think! Don’t just “parrot” back the information!

Where to look for help Use the study guides and on line helps Tutoring center LSE 203 Form a study group Counseling center Disability Services Ask your teacher !

Classroom Etiquette Turn off pagers and cell phones ! No tobacco use of any kind Be considerate of others: Take out what you bring in. Talk to me, NOT your neighbor! Do not ask for grades over the phone or internet.

Academic Integrity  Use Professional ethics  NO:  Plagiarism  Cheating  Allowing others to copy from you  Penalties can be severe !!

Science begins with questions Scientific Method Hypothesis – “an educated guess” about how something works  Must be testable to be useful  Can test by experimentation

What makes a good experiment? Control (s) Test group(s) Results:  Can only disprove the hypothesis – can never “prove” that it is true  Use statistics because responses can differ  Causation vs. correlation  Was your experimental design flawed?

Theory Is the “best guess” we have at this time A set of interconnected hypotheses that have withstood repeated experimental testing.

How are all organisms alike? Made of organized parts Made of cells Perform chemical reactions Obtain energy from their surroundings Respond to their environment Mature (change) over time Reproduce Have a common evolutionary history

Homeostasis : maintaining a constant internal environment in spite of changes in the external environment.

Cells Prokaryotic cells lack a nucleus and membrane-bound organelles (bacteria) Eukaryotic cells contain a nucleus and have organelles

How do organisms differ ? 3 Domains : Archaea, Eubacteria, Eukarya Kingdoms: Protista, Plantae, Fungi, Animalia Phylums, Classes, Orders, Families, Genera, Species Adaptations Evolution Natural Selection
