1st: Write down your TALE 2nd: Put your homework in the middle of your desk 3rd : Bellringer – Sept 10 A cube has a side of 5 cm. It has a mass of 250 grams. The density of the cube is… a. 50 g/cm3 and will float in water b. 2.0 g/cm3 and will float in water c. 50 g/cm3 and will sink in water d. 2.0 g/cm3 and will sink in water 2. Oil floats on water. The most accurate reason for this is… a) oil is less dense than water b) oil is immiscible (does not dissolve) in water c) oil is both less dense and immiscible with water d) water is heavier than oil

Notecards! As I told you yesterday, today is the last day. Once we get going with what we are talking about today, raise your hand and I will come and check your cards. If you don’t show my your cards by today, you will get a ZERO

To sum up yesterday’s lab… The regular Coke is the only can that should have sunk All other Cokes: Diet Coke, Coke Zero, Diet Coke with Splenda…should have floated This is because Coke is the only one with real sugar. When you use “fake” sugar you have to use a lot less. There is more sugar in the regular Coke, making in more dense than the others.

Science Fair Like it or not…

Before we begin… You may NOT!... Kill animals Feed, touch, or molest animals. Have any sort of project involving vertebrates (animal with a spine) Feed, feel, touch, taste, molest, kill, maim, tick off, or hurt people. Make nuclear weapon models (this goes for bombs and firearms too) Do experiments using poisons

Dates (Subject to Change) Hamilton Science Fair – Early Jan. Proposal papers – Sept. 22nd Research Paper – Dec. 14th Final Project – Jan. 11th, 2011 HISD Science Fair – Feb. 2011 SEFH Science Fair April 7-9, 2011 Not sure if we’re competing in this one. Finding out soon.

How will I grade it? Poster Board = Test Grade Journal = 2 quiz grades Research Paper = Test Grade Paper Work = Test Grade Model = Extra Credit 100 points to tests grades Abstract = Extra Credit 100 points to quiz grades. If you are planning on being in the Hamilton Science Fair, this is required! Be Warned! If you are in a group you will get a grade based on what your group turns in!

Today’s Agenda Before you leave today, you must: Group or individually??? Partners must be in THIS class! I have final say on groups – NO CHANGES Please be responsible in choosing your group – this is a VERY big percentage of your grade! Begin brainstorming Science fair Ideas! You must have 5 ideas you’re interested in by the time you leave class Projects must be quantitative (quantity, hard data, numbers) Must follow guidelines stated earlier Follow your interests! Think about questions you would like to answer. Projects must be approved by SRC

Getting Started! If you’re going to do a group, visit your friendly neighborhood lab assistant and let them know who your partners will be. Wait in line quietly and patiently! If you’re flying solo, come and let that lab assistant know!

Worksheet On the worksheet start jotting down your ideas for the science fair on a separate sheet of paper. Pick your favorite one and write a paragraph on the worksheet about what you are think about doing. This will be due back to me by Tuesday. I will return next white Friday.
