to graduate and move on to bigger and better things.

Requirement• Complete all assignments• 3-ring binder at least 1 ½ to 2 inches• Notebook check everyday of a test• Bound composition notebook for

starters• Highlighter• Optional: coloring pencils

Grading Scale

• Test and Major Projects count 50% of your grade

• 25% is quizzes and labs• 25% is homework and classwork• I do give POP QUIZZES

Rules and Procedures• Refer to the syllabus

• ATTENDANCE Policy– Refer to the syllabus

Portfolio• Your responsibility• Attendance sheet First• Objective Report Second• Remediation Sheet Third• Keep only test and quizzes in the folder• Everything else goes in your notebook.

The Language of Science

• Scientific Vocabulary is a mix of small words that are linked together to have different meanings. If you learn the meanings of the little words, you’ll find scientific vocabulary much easier to understand.

• LET’S PRACTICE

The Language of Science

• Mircometer: small mearsurement– Micro: small– Meter: measurement

• Anaerobic:– An: not– Aero: oxygen

• Dermatitis:– Derm: skin– itis: inflammation, disease

Your Turn Use the table to guess the

meaning of each of the following terms

• Arthropod• Bilateral• Abiotic• Biotic• Cytology

• Hemophilia• Epidermis• Chlorophyll• Monosaccharide• Photosynthesis

LAB SAFETY

Safety Quiz on Friday

• Follow all Teacher Directions• Report all injuries or accidents• No Broken glassware in trash can

– Must be placed in a cardboard box• No eating or Drinking• Use proper lab attire (gloves, goggles, apron)• Pull Acid into Base, Not Base into Acid• Never « horse round » or play during labs

Safety Quiz on Friday

• Never mix chemical unless you are told so• Know the correct way to smell

– Waft the flumes

• Always point the top ends of test tubes that are being heated away from people

• Know location of the fire extinguisher, eyewash station, safety shower, fire blanket

Scientific Method• Make a Observations• State the problem• Hypothesis• Experiment

– Control/Experimental Group– Dependent/Independent Variable

• Date Collection– Quantitative/Qualitative

• Conclusion• Repeat

• Control Group: Use as a comparsion (Placebo)• Experimental Group: Tested group• Independent Variables: something that is

changed, What is tested• Dependent Variable: something that might be

affected by the independent variable– What is observed or measured

Scientific Method

Types of Data• Quantitative Data:

– Numerical Data• Examples: graphs, charts, tables

• Qualitative Data:– Written description– Purely observations

• You use your senses to make observation.

ExamplesIdentify the control, IV & DV

• Students of different ages were given the same jigsaw puzzle to put together. They were timed to see how long it took to finish the puzzle.

• The higher the temperature of water, the faster an egg will boil.

• The temperature of water was measured at different depths of a pond.
