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

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 n Tutoring center LSE 203 n Form a study group n Counseling center n Disability Services n Ask your teacher ! n

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 Ø NO: Ø Ø Plagiarism Ø Cheating Ø Allowing Ø others to copy from you Penalties can be severe !!

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

What makes a good experiment? Control (s) n Test group(s) n Results: n ¨ 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 n A set of interconnected hypotheses that have withstood repeated experimental testing. n

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

n 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) n Eukaryotic cells contain a nucleus and have organelles n

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