Wednesday of this week students MUST turn in the General design for experimental Design worksheet for their science fair project.
Science Fair Schedule of deadlines:
Week ending October 17th, 2014: Students should now have an idea how to conduct their experiment and what research needs to be done.
Week Ending October 24th, 2014: Wednesday of this week students should have completed to turn in the completed General scientific experiment sheet. General layout for a scientific experiment template. Hypothesis should be in the If/Then format.
Week ending October 31st, 2014 (Thursday and Friday) Students should have their background research completed and in rough draft form WITHOUT the conclusion. Turn in for review. This written paper should include all background information on their chosen idea and subject and include; why this project interests them and what they hope to find out through their experiment. It should incorporate ALL of their source materials properly cited using quotation styles within the document... EXAMPLE... (Allison, 2014) . It should thoroughly explain their preparations, materials used, procedures and discuss what they think their hypothesis will show. Discussion should include how this will benefit the future and what the next steps they will take in the process. Final draft will be about 2500 words, 12 point Times New Roman font, double spaced. There will be a Title page, Abstract, and Works Cited page created in Easybib. (MLA style)
ALL STUDENTS SHOULD BEGIN THEIR EXPERIMENTS NOW!
Week ending November 7th, 2014 (Thursday & Friday): Student should have their rough draft science mini board completed and ready to be graded. I will check over the boards and make suggestions for improvement
Week ending November 14th, 2014 (Thursday & Friday): We will go to the media center and students will create their title page, Abstract page and their Easybib works cited page.
Week ending November 21st, 2014 (Thursday & Friday): Student projects are due including the mini board, the word processed research paper in a plastic or folder cover. Students should indicate if they have a desire to go on to the county science fair at this time.
Week ending November 28th, 2014 (Thanksgiving Week) Students will take their boards home and begin working on their big boards for the county fair or finalize their mini board for the school science fair.
Week Ending December 5th, 2014 (Thursday & Friday) Students will give a 3 minute oral presentation in front of the class about their project.
December 10th, 2014 5:30pm to 6:30pm School science fair in Media center. Parents and families are welcome to attend!
Today's Lateral Thinking question:Dee Septor, the famous magician, announced that without the aid of any equipment, or assistance, he would walk on the surface of Grass Lake. The following Sunday the crowd came out and witnessed Dee Septor do exactly as he promised. How could he manage this feat without the aid of any special equipment?

History of Atomic Theory (ADV).The Making of the Periodic Table
We've finished up our discussion of scientists and how our current idea of the atom came to be the way it is. Check out the PM update tonight for a review of those guys and their discoveries. Today we began looking at the periodic table. This is Chapter nine in our textbooks. We began going over the worksheet The Atom. By the end of the period today, I will collect the first page of this packet. It should be competed front and back.
The worksheet: Atomic Basics. Is for the Advanced classes. It will be used as we begin our discussion today. It is expected that students will read through the section on the Periodic table (Chapter 9) in their book and use the notes I gave them to complete the sheets.
If laptops are available we will visit this site and learn a little bit about how atoms are constructed. Build an Atom
Here is a link to my Power Point so students have the notes! The Periodic Table
Periods 1,2,5 & 6 Are to read Chapter 9 section one and completed the section review Which will be due Tuesday when class begins. Do the work right on the pages and tear them out and return to me by placing them in the homework baskets. Read pages 339- 347 and do the reading checks as well as the Foldable listed on page 343. Do the Try it activity on page 347.
Periods 3, & 4 Should complete Atomic Basics (All classes)
The Atom and the Periodic Table.(Advanced classes only)
Watch these two videos on matter.

Cool Website Alert
The Adopt an Atom project that was listed in the blog Monday of this week is postponed! We are not to the point in class where we are ready to begin this yet. STAY TUNED!
We currently are covering the materials from Chapter 8 in our text book. Students who are out sick or need extra practice should review Chapter 8 beginning on page 306.
For Wednesdays and Thursdays quiz know the following:
Democritus- 400BCE First idea of a small uncuttable particle called Atomos. No scientific evidence, simply though
Aristotle- 400BCE Did not believe in atoms, but said there were 5 basic elements, Air, Earth, Fire, Water, and Aether that made up everything. No scientific evidence, just thoughts. This was our model of the atom for over 2000 years!
John Dalton- 1800's School teacher who studied gases came up with 5 ideas (supported Democritus'ideas). He is the Father of the Atomic Theory 1. All matter is composed of atoms. 2. Atoms cannot be created or destroyed. 3. All atoms of the same element are identical.(different types of elements have different types of atoms) 4. Chemical reactions occur when atoms are rearranged. 5. Compounds are formed by the combinations of two or more different kinds of atoms. first person to use the scientific method to prove his ideas.
J.J Thompson- 1901 English Scientist who worked with the Cathode ray tube. Atoms CAN BE divided. Named the electron- a negatively charged particle in an atom. His model is called the plum pudding model and his atom was a hard sphere that was mostly positive, but had the electrons embedded in this positive stuff. Electrons can't move.
Earnest Rutherford-Late 1800's Friend of Thompson and was trying to prove Thompson's model of the atom. Used the Gold Foil experiment where he fired alpha particles (+) at a piece of gold foil with a detector scree set up around it. He expected the beam to pass right through the foil (because Thompson's model said the atom was mostly positively charged). Instead the alpha particles were deflected at strange angles. Rutherford discovered and named the proton (a large + mass at the center of the atom), and realized the atom is mostly empty space.
Bohr- 1920's Responsible for moving us to the modern model of the atom (The Bohr model) Said, electrons(-) can only exist on very defined energy levels he call shells/ orbitals. Electrons cannot exist between shells, but CAN be moved up to another level by giving an electron (-) a very small amount of energy he called a quantum
DeBroglie- 1920's. Said electrons(-) and other forms of energy can be either particles OR waves and we should think of them as waves. We can think of an electrons energy better by looking at it's wavelength instead of the quanta it has.
Heisenberg- 1920's Heisenberg Uncertainty Principle which states you can't know both the speed and position of an electron but you can know one or the other.
Schrodinger- 1930's. Described the wave equation that unified several theories and said that we cannot pinpoint any electron within an atom but that electrons could be found in very distinct areas of probability within what he called the electron cloud. Father of the Electron cloud model of the atom. Gave us Schrodinger's Cat postulate that says atoms exist in a state of superposition until our observation forces nature into a course of action.
James Chadwick- 1930's. Discovered the neutron. A large particle with no charge at the center of an atom that stays near the protons and eeps them from bumping into each other.
