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 !

Science begins with questions

Scientific Method Hypothesis – “an educated guess” about

how something worksMust be testable to be usefulCan 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 differCausation vs. correlationWas 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
