The Top 75 ‘Pictures of the Day’ for 2012 *Update: The Top 100 ‘Pictures of the Day’ for 2012 have just been published. Click here to check out the most up-to-date post! After the positive reception from last year’s “Top 50 ‘Pictures of the Day’ for 2011“, the Sifter promised to highlight the top 25 ‘Pictures of the Day‘ at the end of every quarter, eventually culminating in an epic Top 100 for 2012. It’s hard to believe we’re already into the final quarter of 2012. *Please note the photographs themselves were not necessarily taken in 2012, they just happened to be featured as a ‘Picture of the Day’ this year. Enjoy! Collection Online Featuring nearly 1600 artworks by more than 575 artists, the Collection Online presents a searchable database of selected artworks from the Guggenheim’s permanent collection of over 7,000 artworks. The selected works reflect the breadth, diversity, and tenor of the Solomon R. Guggenheim Foundation’s extensive holdings from the late 19th century through the present day, and are continually expanded to include a larger representation of the museum’s core holdings as well as recent acquisitions. In addition to highlights from the Solomon R. Learn More about the Collection

Levantine Arabic Levantine Arabic (Arabic: اللهجة الشامية‎, al-lahjah aš-šāmiyyah), is a broad dialect of Arabic spoken in the 100 to 200 km-wide Eastern Mediterranean coastal strip.[2] It is considered one of the five major varieties of Arabic.[3] In the frame of the general diglossia status of the Arab world, Levantine Arabic is used for daily spoken use, while most of the written and official documents and media use Modern Standard Arabic. It is part of Eastern Arabic that includes Mesopotamian Arabic and penisnsular Arabic along with Levantine. On the basis of the criterion of mutual intelligibility, Levantine Arabic could be regarded as a self-standing language (with different variants or dialects as explained below), as distinct from other members of the Arabic language family such as Egyptian Arabic, Maghrebi Arabic or Peninsular Arabic, in the same way as French, Spanish, Italian and Romanian are all descended from Latin but are separate languages within the family of Romance languages.

FREE -- Teaching Resources and Lesson Plans from the Federal Government Density Tower - Magic with Science at Steve Spangler Science Start your column by pouring the honey into the cylinder. Now, you will pour each liquid SLOWLY into the container, one at a time. It is very important to pour the liquids slowly and into the center of the cylinder. Make sure that the liquids do not touch the sides of the cylinder while you are pouring. It’s okay if the liquids mix a little as you are pouring. The same amount of two different liquids will have different weights because they have different masses. To test this, you might want to set up a scale and measure each of the liquids that you poured into your column. Density is basically how much "stuff" is smashed into a particular area... or a comparison between an object's mass and volume. The same goes for the small objects that you dropped into your density column. In the materials, we had you grab a bunch of miscellaneous tiny objects. When all the liquids and small objects have been added to your density tower, you will have what appears to be a magic column.

A List of Books | 623 of the Best Books Ever Written Schools Should Teach Science Like Sports Suppose you wanted to teach children to play baseball or softball. How would you go about doing it? One approach might be to sit them down and start having them memorize the rules of the game, the dimensions of the field, the names and statistics of past players, and a host of other facts. You would stop teaching them periodically to review the material in preparation for multiple-choice assessment tests. The students who showed a great aptitude for memorizing large numbers of facts could go into honors classes where they would memorize even larger numbers of facts. At the end of the process, without ever leaving the classroom, how well do you think the children would be able to play baseball or softball? Why have we thought that this process would work with teaching science to children? The Next Generation Science Standards (NGSS) are intended to be a cure for this approach. Here is an example of one performance expectation, taken from high school Earth and space science courses:

Iraqi Arabic Mesopotamian Arabic, also known as Iraqi Arabic, is a continuum of mutually intelligible Arabic varieties native to the Mesopotamian basin of Iraq as well as spanning into central and northern Syria,[2] western Iran,[2] southeastern Turkey,[3] and spoken in Iraqi diaspora communities. In its various forms, it is the official vernacular of Iraq.[citation needed] History[edit] Due to Iraq's inherent multiculturalism as well as history, Iraqi Arabic in turn bears extensive borrowings in its lexicon from Aramaic, Akkadian, Persian, Kurdish and Turkish. Varieties[edit] Different Arabic dialects in the Arab world Mesopotamian Arabic has two major varieties. The southern (Gelet) group includes a Tigris dialect cluster, of which the best-known form is Baghdadi Arabic, and a Euphrates dialect cluster, known as Furati (Euphrates Arabic). Distribution[edit] References[edit]

Proton NMR Table The broad ranges shown at the bottom of the chart (orange color) are typical of hydrogen bonded protons (eg. OH and NH). These signals are concentration and temperature dependent. Inductive deshielding effects of electronegative substituents are roughly additive, as the following data suggests. Furthermore, the longer-range influence of such substituents is apparent (although diminished) in compounds such as CH3-CCl3, d = 2.72 ppm, and CH3-C(OR)3, d = 1.46 ppm. Anisotropic effects are common in p-electron systems, and are often responsible for atypical chemical shifts. The 14 p-electron bridged annulene on the left is an aromatic (4n + 2) system. Conjugation of a double bond with a carbonyl group perturbs the carbon resonances of both groups. Examples of the effect of multiple substituents on a carbon atom are shown in the following table.

Understanding Science BanksyInside - A Digital Magazine Dropping What's Fresh on the Web The mysterious Banksy just released some new paintings on his website. You heard it right, Banksy painted on a canvas. All Banksy fans will appreciate. Here are a few of my favourites. 5 Quick Tips for Secondary Classroom Management That Actually (I Promise You!) Work This fall I will begin my sixth year of teaching, which is still weird to see written down because it seems like just yesterday I was struggling through my first. (And second. And probably third, too, for good measure.) Classroom management was my biggest struggle in those beginning-teaching years. I went in suspecting I would have classroom management in the bag because I'd had pretty extensive experience working with kids from babysitting, being a camp counselor and other volunteer-type roles. In my first year, I had no procedures in place and thought that my students wouldn't learn if I wasn't always nice to them. In my second year, I overcompensated for my leniency the previous year and behaved somewhat like a dragon. My third year is when things started to even out. Classroom management isn't like following a recipe, where you follow exact steps and end up with a beautiful finished product. 1. A quiet voice is way more effective than a loud one in the long run. 2. 3. 4. 5.
