Welcome to Mrs. Enders’ Biology 11 Class

Welcome to Grade 11 Biology! This year, we delve into science skills, molecular interactions, evolution, organism organization, and ecology. Remember key concepts from last year's chemistry and biology, and get ready for new challenges. We'll cover various topics such as cell functions, DNA structure, natural selection, and ecological relationships. Active participation, respect for each other and the environment, and consistent work are crucial for success. Bring your supplies and commitment to make this a great year in science!

  1. Welcome to Mrs. Enders’Biology 11 Class

  2. Welcome to Grade11 Science!What do you remember from last year? • Chemistry • Parts of the atom, naming compounds, reaction types, acids/bases • Biology • Food Web, nutrient cycles, Ecosystems • Physics • Radioactivity, velocity, acceleration, scalars/vectors • Plate Tectonics • Wegener, pangaea, earthquakes

  3. Why are you here? Why is science important? Activity: - You can tell the temperature outside by counting cricket chirps - Kinking an electrical wire - Drinking water cures disease - Spaghetti farming Neil Degasse Tyson…

  4. Answers: • Cricket Chirps • Kinking an electrical wire • Water • Spaghetti farming

  5. How to make this year great…

  6. Class Rules and Expectations: 1) Respect Yourself and Others - Don’t do anything to harm yourself or anyone/thing else. -Treat others like you like to be treated.

  7. 2) Respect Effort and Learning - NO IPODS/MP3’s allowed! - Attendance is mandatory – if you are away, bring a note ASAP! - Don’t be late!!

  8. Do your homework to the best of your ability – neatly and on time!! - Bring all supplies to every class! Check the website: daily.

  9. 3) Respect your community and the Environment: - Clean up after yourself - Be careful with borrowed equipment/books - No gum is allowed - Food and closed drinks are allowed as long as they don’t cause a problem/mess

  10. So what are we learning about this year? • 1) Science Skills/Processes of Science (Approx 1 week and ongoing through the course) • A) What is science? • - Scientific Method • - Presenting and interpreting Scientific Data • Graphing, designing experiments

  11. 2) Interactions at molecular and cellular levels - Cell structure and function - (A)sexual reproduction - Energy transformations in cells - Single and multi-celled organisms - Viruses/Bacteria 3) Evolution - basic structure of DNA - agents of evolutionary change - adaptation, natural/artificial selection - genetic modifications - Convergent/divergent evolution and speciation - gradual change model vs punctuated equilibrium 4) Organism organisation - Levels of organization (taxonomy) - Binomial nomenclature - Domains vs Kingdoms - Trends in complexity among life-forms

  12. - Plant Biology - Green algae - mosses - ferns - gymnosperms - angiosperms - monocots and dicots - Animal Biology - Different phyla (families) – classify and compare - comparing how different animals - reproduce - eat - excrete - advantages and disadvantages to different life functions

  13. 8) Ecology (if time permits) - Succession - Producers vs consumers – food chain/web - energy flow in the ecosystem - Populaitions, growth, carrying capacity, steady state - Symbiotic relationships

  14. Marking your work... • Class work – 80% of your overall mark. • Final Exam – 20% of your overall mark. • Your overall assessment(mark) will be based on Tests/Quizzes, so it will be greatly to your advantage to take advantage of the practice opportunities – i.e. homework.

  15. Marks Breakdown…

  16. Supplies • A 3 Ring binder with paper and dividers • Dividers can be organized as you like – I suggest the following… • Notes • Homework/Assignments • Labs • Quizzes/Tests • Scrapwork

  17. Pencils, Pens (Blue and Red), Eraser, Scientific Calculator, Ruler • Other supplies will be mentioned as needed. Please bring all supplies to every class!!!

  18. Grade Breakdown • A = 86% – 100% • B = 73% - 85% • C+ = 67% - 72% • C = 60% - 66% • C- = 50% - 59% • Fail = Below 50%

  19. In Summary… Come see me or another teacher for help as soon as you have problems Let’s work together to make this a good year!
