Welcome to Biology Mrs. Erin Oxendine

Goal To prepare you for the EOC Must score a Level 3 or Level 4 It is a graduation Requirement I have high expectations because I WANT YOU 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.

Examples Identify 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.

Designing Investigations

The greater the amount of soap in a soap and water mixture, the bigger a soap bubble can be blown.  Design an investigation to test this hypothesis.  Identify the variables  What exactly will be changed? How will it be changed?  What exactly will be measured? How will it be measured?

The farther a ball drops, the higher it will bounce.  Design an investigation to test this hypothesis.  Identify the variables  What exactly will be changed? How will it be changed?  What exactly will be measured? How will it be measured?
