media type="custom" key="15397482"Human Heart and Circulation 2 Please review these videos so you know how your heart works "by heart." Stop these videos as you wish to complete your own explanation, that is narrate the entire process, when you are ready; use your notes and what you learned in class as well; thank you. You will be asked to do an oral narration in class for a quiz grade. Also be prepared tp answer questions after your presentation. Due date TBA. Ms. Kahn 2/24/2012

April 23, 2012: Review Homework for the day you return to school: Watch this ( video 0.) and be ready to discuss. The vidoe appears here on top of the two circulation videos. =April 7, 2012 Post: DNA MADE OF CANDY EXTRA CREDIT PROJECT FOR APRIL!!! =

ALL BIOLOGY ONE STUDENTS: If you . .want to raise your grade, construct a candy DNA and bring to class
=[|EXTRA CREDIT CANDY DNA]. Bring it in by Wednesday April 11 for up to 100 points of Extra Credit, depending upon correctness and quality. Any sincere effort through April Break will earn you at least 20 extra credit points. Click the link above for explicit and perfect directions.= Make sure there is a hook on yo ur modle candyDNA so it can be hund in the classroom for all to see.

= = = = = **WATER Study Guide** **Review ALL 4 SECTIONS BELOW FOR WATER QU**IZ ** : This should make up the basis of a really good guide** for you once you have completed all parts: Watch video again/ fill in portion below/and then review and study Short PowerPoint. After that, you have only diffusion and osmosis to deal with--- that's number 4. END. Study, Study, Study. I am available to stay after school Thursday Dec 8 for a full review. Plan on staying for at least half an hour or so: It will begin at 2:15 pm in room 113.= 1. This is the part of the Modern Marvels WATER that you will need to know for this quiz! Remember to rescreen the first part of this through 3 minutes and 5 seconds. That's all you will need from this source. You may want to view it several times, though, until you learn what you need to.

2. FILL in SECTION You will still need to fill in the answers to this (some did this in class--but now that you know more do a better job--and ask me, the teacher, about anything you do not know BEFORE the day of the QUIZ). WATER QUALITIES: BE SURE YOU CAN ANSWER ALL FIVE QUESTIONS INCLUDING PARTS A AND B FOR EACH QUESTION: Simply:__You must find and explain at least one example of each of five unique qualities of water to show how that quality is essential to Life on Earth.__ Your explanations and writing must make sense to a sixth grader and to an adult—both. A. How is each qualitiy critical to life on earth? Also explain the quality if you need to. B. Make sure you answer this question in a full sentence or two and then provide at least one precise __example__ from real life.

1.Quality: Ice is less dense than liquid water A. B. 2. Quality: Water has a high surface tension (cohesion of water –sticks to itself))  A. B.  3. Quality: Water exhibits capillary action (adhesion of water- sticky to other substances)  A. B.  4. Quality: Water is can be exposed to large changes in temperature while its temperature remains stable* (* This may be expressed in different “words” in your sources- but meaning the same thing)  A. B.  5. Water is an outstanding solvent (because it is a polar molecule); it is called the “Universal Solvent”  A.B.  3. Below: Open a scanned version of the PowerPoint on Water to review information -- also, there is one page after that you will want to "redo" in advance of the quiz-- create /draw a model of the water molecule- include protons and electrons:  4. Osmosis and Diffusion Finally: LOOK IN YOUR NOTES AND PACKET....Know the definition and characteristics of diffusion, osmosis, and be able to show which way water molecules will flow via osmosis in a variety of solutions (for example, salt water, plain water, and the like). Also know the meaning of : Dynamic equilibrium, solute, solvent, semi-permeable membrane, area of lesser and greater concentration/s. Know what kinds of diagrams and arrows mean: flow out, flow in, and dynamic equilibrium. Understand when a cell is hydrated and when it is dehydrated. Know what can happen to plant and animal cells with too much or too little water in them. END.
