  1. Welcome Back to Science! January 30, 2012

  2. Do NOW!!!! ***THIS MUST GO IN YOUR SCIENCE NOTEBOOK! MAKE SURE YOU LABEL AND DATE THIS “DO NOW!” • What do you think is the most important organelle in the cell? Why? • Name two organelles that occur in plant cells but not animal cells. • Tell me something really interesting you learned while I was out.

  3. Agenda 01/30 • Science Notebook Check on FRIDAY 02/03 • Review Classroom Policies & Procedures • Science Fair Projects—Due TODAY! • I will still accept through the week with point deductions • Presentations Start tomorrow—unless you want to present today • Introduction to Protists • What is a Protist? • What are the different types? • How are they alike? How are they different? • Why exactly do we need to know this? • Test Corrections: Due on Wednesday 02/01

  4. Mrs. Ward’s Classroom Policies & Procedures A review since we have been apart for so long….

  5. When you get to class… • Enter quietly • Sit down in your assigned seat as quickly as possible. • If the desk are moved (which I do frequently based on the day’s activities) find an available seat. This is a free day and I am allowing you to choose your seat. • Start on your DO NOW! There should be no talking! • WHEN THE SECOND BELL RINGS, IF YOU ARE OUT OF YOUR SEAT YOU ARE TARDY!!!

  6. Bathroom Policy • Once a week during science • Don’t ask if: • You’ve already been this week • You don’t have an agenda • Mrs. Ward is teaching (aka “on the rock”) • Bathroom Policy includes Lockers and Water Fountain Breaks as well

  7. Phones, Music, & Food • Use some common sense. If I see it, I am going to take it. I do not want to take your things, so please don’t make me. I have let too many people get away with eating and listening to music. • Food—I am going to throw it in the trash and it is gone forever. • Phone/iPod—You can get it at the end of the day or your parent/guardian can come get it • I am going to start finding academic activities that allow you to use your phone technology. I can only do this if students do not abuse this privilege.

  8. Dress Code • Please follow the dress code. It is my responsibility to make sure you are doing so. I do not want to be a “nag” about your shirts and hoodies. • You know the dress code. Don’t make me remind you constantly. Is it really that hard to tuck in a shirt? 

  9. Transitions/Group Work • Quietly and Quickly…otherwise we will be forced to only do individual work and lectures. How boring is that? • Labs…You should be on exceptional behavior.

  10. 5-4-3-2-1Countdown • When you hear me start the 5-4-3-2-1 countdown… • CLOSE YOUR MOUTH • STOP MOVING • EYES ON ME • AWAIT DIRECTIONS • Let’s PRACTICE!

  11. Other General Guidelines I should not remind you… • STAY IN YOUR SEAT. If you need to get up or have a problem, just raise your hand and ask. I am very flexible with your needs. • DON’T TALK WHEN I AM “ON THE ROCK.” • The constant interruptions are making it very difficult to get through the lesson and onto individual and group work.

  12. Other General Guidelines I should not remind you… • SERIOUSLY…I should not even have to say not to throw things. SERIOUSLY. • DO NOT YELL OUT…EVEN if it is related to science class!!!! I want to hear from you, but not when you are calling out.

  13. FINALLY…Yes, Finally… • I dismiss the class, not the bell. • Stay in your seats and sit quietly until I dismiss you. • I will not write passes if you are late to your next class because you are being held.

  14. UPDATES What you need to know

  15. New stuff while I was out… • My wiki is finally up and operational • The address is: http://annaward.cmswiki.wikispaces.net/ • I’m working hard to make this a cool space for our class • Go check it out! • Parent letters • Easy 100 quiz grade • Return ASAP • No later than Friday, 02/03

  16. Science Fair Projects • Due today • If you want to present today, raise your hand • 5 presentations a day until we are done! • Students in my Cougar Time will present during CT • Take 3-5 minutes to tell us about your project • Remember, an accompanying Power Point or Prezi earns you 5 EXTRA POINTS!

  17. Presenting Tomorrow: • Cougar Time: • Luis, Ana D., Ahriana, Kevin, Evan • 2nd Block: • Charles, Diamond, Mariah, Sarah, Dianelys • 3rd Block: • Brian, Alex, Ana A., Alfie, Jonathan C. • 4th Block: • Arlette, Nora, Emanuel, Hemerson, Quinasia • 5th Block: • Shikim, Jaly, Tyana, Jakel, Atif

  18. Introduction to Protists So what is a protist anyway?

  19. A protist is…(write down the stuff in blue in your science notebook) • Protists belong to the Kingdom Protista, which includesmostlysingle-celled organisms that do not fit into the other kingdoms. Characteristics of Protists: • mostly unicellular, some are multicellular (algae) • most live in water (though some live in moist soil or even the human body) • ALL are eukaryotic (have a nucleus)

  20. How are they classified? Protista = the very first Classification of Protists: • how they obtain nutrition (How they eat!) • how they move

  21. We will be studying 4 types of protists: • Amoeba • Paramecium • Euglena • Volvox

  22. Amoeba • An amoeba Moves using “false feet” or pseudopodia • Eats food by surrounding and engulfing it • Does not make its own food (heterotroph) • Movie of an amoeba eating: http://www.youtube.com/watch?v=ojrkxmD6tT8 • Movie of an amoeba moving: http://www.youtube.com/watch?v=7pR7TNzJ_pA&feature=fvwp

  23. Paramecium • Moves using hair-like Cilia • Has two nuclei • Ingests through a mouth pore • Stores food in food vacuole • Releases waste through an anal pore • Heterotroph like the amoeba • Paramecium moving & eating: http://www.youtube.com/watch?v=zS0f82ZJtvk&feature=related

  24. Euglena • Characteristics of both plants & animals • Has chloroplasts to produce food through photosynthesis (autotrophic) • Has light sensitive eye spot • Can also surround & engulf food • Has whip-like flagellum for movement • Video of Euglena: http://www.youtube.com/watch?v=ZHZZKwrYm4g

  25. Volvox • A type of algae • Actually form large spherical (like a ball) colonies of single-celled organisms • AS MANY AS 50,000 in one colony! • Although they are all individual organisms, they work together to act like one multicellular organism • Can digest food (heterotroph) as well as produce their own food through photosynthesis (autotroph) • Have flagellafor movement • http://www.youtube.com/watch?v=He9FSeGRi3A&feature=related

  26. Test Corrections…Due WED! • Please make corrections on your test in a different color ink. • Turn it in for 10 additional points on your test. • I will give students a chance to retake the test in class. • Once again, it is due on WEDNESDAY.

  27. 3-2-1 Ticket out the Door • In your science notebook (remember…I am checking on Friday) please write down the following: 01/30/12 3 Things you Learned Today 2 Things you are still confused about 1 Thing you would like to know more about
