Welcome Back to Science!
January 30, 2012
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.
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
Mrs. Ward’s Classroom Policies & ProceduresA review since we have been apart for so long….
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!!!
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
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.
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?
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.
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!
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.
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.
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.
UPDATESWhat you need to know
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
Science Fair ProjectsDue 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!
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.

5th Block: Shikim, Jaly, Tyana, Jakel, Atif
Introduction to ProtistsSo what is a protist anyway?
A protist is…(write down the stuff in blue in your science notebook) Protists belong to the Kingdom Protista, which
includes mostly single-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)
How are they classified?Protista = the very first
Classification of Protists:
how they obtain nutrition (How they eat!)
how they move
We will be studying 4 types of protists: Amoeba
Paramecium
Euglena
Volvox
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
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
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
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 flagella for movement http://www.youtube.com/watch?v=He9FSeGRi3A&f

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.
3-2-1 Ticket out the Door In your science notebook (remember…I am
checking on Friday) please write down the following:
