Turn in your FINDS Research Model today


Science Fair Schedule of deadlines:
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:

Suppose a squirrel is behind the trunk of a tree, which,it keeps between itself and a hunter who is circling the tree. In this case does the hunter actually walk around the squirrel? Explain why or why not.

The Making of the Periodic Table Part 2: How to use the tableChemical and physical properties Beginners.

Today's Class:

Students finished work on their cereal atoms Periods 1,2,3,4,5 after receiving a few notes on the periodic table.

Period 6 received their notes on the periodic table

The Anatomy of the Periodic Table

As you are probably well aware, in the periodic table, elements are arranged in order of increasing atomic number. The 18 vertical columns of the table are called groups or families, while the seven horizontal rows are called periods and correspond to the seven principal quantum energy levels, n = 1 through n = 7.

On the right side of the periodic table is a dividing line resembling a staircase. To the left of the staircase lie the metals, and to the right of the staircase lie the nonmetals. Many of the elements that touch the staircase are called metalloids, and these exhibit both metallic and nonmetallic properties. Study the diagram below and memorize the names of the different types of elements, because you will definitely see questions about these groupings on the test!

Metals are malleable, ductile, and have luster; most of the elements on the periodic table are metals. They oxidize (rust and tarnish) readily and form positive ions (cations). They are excellent conductors of both heat and electricity. The metals can be broken down into several groups.

Transition metals (also called the transition elements) are known for their ability to refract light as a result of their unpaired electrons. They also have several possible oxidation states. Ionic solutions of these metals are usually colored, so these metals are often used in pigments.

The actinides and lanthanides are collectively called the rare earth elements and are filling the f orbitals. They are rarely found in nature.

Uranium is the last naturally occurring element; the rest are man-made.

Nonmetals lie to the right of the staircase and do not conduct electricity well because they do not have free electrons. All the elemental gases are included in the nonmetals. Notice that hydrogen is placed with the metals because it has only one valence electron, but it is a nonmetal.

Here are some specific families you should know about, within the three main groups (metals, nonmetals, and metalloids):

Alkali metals (1A)—The most reactive metal family, these must be stored under oil because they react violently with water! They dissolve and create an alkaline, or basic, solution, hence their name.

Alkaline earth metals (2A)—These also are reactive metals, but they don’t explode in water; pastes of these are used in batteries.

Halogens (7A)—Known as the “salt formers,” they are used in modern lighting and always exist as diatomic molecules in their elemental form.

Noble gases (8A)—Known for their extremely slow reactivity, these were once thought to never react; neon, one of the noble gases, is used to make bright signs.
Students finished creating a three dimensional model of the element they were assigned.
This is Chapter nine in our textbooks.

Here is a link to my Power Point so students have the notes! The Periodic Table

Today's homework:

Periods 1,2,5 & 6 Are to read Chapter 9 section three and prepare for discussion or to ask questions.
Periods 3, & 4 Should complete
The worksheet: Atomic Basics.The Atom and electron levels. is for the Advanced classes. This will be due Wednesday of this week, completed. (Information can be found in chapters 8 & 9 in our book.)

PM Update:

We currently are covering the materials from Chapter 9 in our text book. Students who are out sick or need extra practice should review Chapter 9 beginning on page 336.
