CCS Social Studies - May - June 2014

CCS Social Studies - May - June 2014

8th Grade social studies students have been focusing on the 4-I's: industrialism, immigration, inventions, and imperialism.  Each "I" influences the others throughout the late 1800s and early 1900s.  Students debate whether figures like Rockefeller, Carnegie, Vanderbilt, and Morgan are captains of industry or robber barons.  How does the wealth inequality of the Gilded Age compare with the wealth inequality of today?  Is the video in this link ( https://www.youtube.com/watch?v=QPKKQnijnsM&sns=em ) propaganda?  What does the data indicate?


Extra credit opportunities for 8th grade students include: 1) researching and presenting on one of the presidents from the Gilded Age (Grant, Hayes, Garfield, Arthur, Cleveland, Harrison, McKinley), 2) Create chapter questions for the book Children of the West, or for the book, Immigrant Kids, 3) Complete the World War I internet search packet.

In 6th and 7th grade social studies (both blue and gold groups), students have recently completed their unit on the conclusion Middle Ages, and are learning about the rebirth after some dark times!  The Renaissance
unit focuses on the big ideas that the arts, philosophy, science, and literature flourish during this time.  It was also a time when people were looking back at what was lost (neo-classical).  These new humanist ways of thinking resulted in challenges to the established religion of the Catholic Church in the time period we call the Reformation.  Could the Reformation have happened without the Renaissance?


Extra credit opportunities for 6/7th grade students include: 1) teach chess to someone outside of middle school, 2) create a modern or local chess set, 3) write an extension of your "pilgrim's" tale, 4) illuminate a medieval letter, 5) create additional Renaissance revolutionaries trading cards, 6) add captions to the medieval comic strip.

Updates from the Math Room

6th Grade

The 6th graders have spent the last several weeks focusing on geometry. We're currently focusing on three dimensional figures. This has allowed for a lot of hands on learning, which is always fun! The other day, as an introduction to surface area, we cut apart empty cardboard boxes to make nets. By looking at the nets, students are able to see each part that makes up the total surface area. We'll be finishing up the year with our last unit on statistics! 

7th Grade

The 7th graders have also been focusing on geometry. We just finished our unit on angle relationships and triangles. We had fun playing with "anglegs" to discover the rules for side lengths of triangles. We're now moving on to two-dimensional geometry. The students will be doing some fun activities with circles where they will discover the formula for circumference and area on their own! They will also be working with one of their favorite values - pi! 

Pre-Algebra

The Pre-Algebra class just wrapped on their unit on statistics. We learned about measures of center and measures of variability. We also learned about biased vs. unbiased sampling methods and which methods are most appropriate. We just started our probability unit. Probability always leads to fun activities involving dice and coins, which they have already experienced! 

8th Grade

The 8th graders just finished up our unit on the Pythagorean Theorem. Students were able to find the missing side of a right triangle or determined if three sides made a right triangle. It was a quick, but fun, unit that the students really enjoyed. We are now starting our congruence and similarity unit where students will study transformations and their affects on shapes. It is always fun to create patterns and designs using transformations! 

Algebra

The algebra students are in the middle of their unit on quadratic equations. We are currently focused on factoring trinomials to solve quadratic equations. This had been challenging, but they're getting the hang of it with lots of practice! As we get close to the end of the year, they will start to prepare for their final exam at the beginning of June!

News from the Science Classroom!

6th and 7th grades!

Having done an excellent job on their science experiments for the science fair, students are now taking on the study of basic chemistry.  They have been studying characteristic properties of substances.  They learned how to measure mass with triple beam balances, and to measure volume by water displacement, or by measuring length, width and height.  They used these skills to help them calculate the density of many different metals, woods, and plastics.  Then they were able to identify "mystery substances" using the density.

We have also been talking about other properties, such as boiling point and freezing point (and trying to imagine how hot it is when metals "freeze" into solids, and how cold it is when oxygen "boils")  We explored the idea of solubility, and how some substances dissolve easily, and others don't.

We posed the question, "How do we use characteristic properties to separate substances?"  Students were challenged to use their knowledge of properties, to separate a mixture of sand, salt and sawdust.  We worked on connecting the names of the properties (density, solubility, and boiling point) to the differences that made it possible to separate them.

Lately, we have been learning about atoms and elements.  Students are thinking about just how small an atom is, and trying to make sense of the fact that they are too small to see, but we have evidence that shows us their properties.  We are distinguishing between elements (made of one kind of atom) and compounds (made of more than one kind... chemically bonded together)

Our study of the periodic table is aimed at helping students know how to use it as a reference tool (not memorize it)  We have been exploring what all the symbols and numbers mean.  We wondered, together, why it is such a strange shape, with some elements sticking out at the top.  Students were given data on each element, and asked to organize it themselves, based on as many different pieces of evidence as they could. They discovered that it's organized by atomic number and atomic mass AND by what the elements combine with and whether they are metals, non-metals or metaloids.

This past week was particularly fun for students (and me too).  We have been looking at the differences between chemical changes and physical changes, and thinking about how chemical changes make new substances.  We saw pure sodium metal react violently with water (it catches fire and explodes), and talked about how sodium, combined with a poisonous green gas (chlorine) makes plain old table salt!  We also burned paper, saw chemicals combine to produce color changes, saw other chemical combinations produce gasses, and 7th graders even saw chemicals produce heat or cold.  Our objective is to see the difference between a physical change and a chemical change, and to understand that after a chemical change, there are new and completely different substances.

Upcoming is another "figure it out yourself" lab (known as student "inquiry" in educational circles)  involving several chemical reactions.  Students will see four chemicals mixed, and evidence of several chemical reactions.  Their job is to figure out which combinations of substances cause which reactions.

Soon we will turn our attention to weather, including how we measure pressure, humidity, temperature and wind, as well as how and why air moves, how clouds form, how we know when and where storms occur, and other weather-related learning.  I am excited to look at data from our new electronic weather station, right at the school!


8th Grade!!

Throughout the year, 8th graders have been working on honing their informational writing skills.  Scientists do experiments, but they also need to communicate clearly about them, and synthesize information they read about science topics.  Clarifying one's ideas, enough to write clearly about them, is an important skill.  The 8th graders wrote about the physics of roller coasters in the fall, they wrote about why planets orbit the sun, and why there are eclipses in the winter, and now in the spring, they are writing about a genetic disorder.

We have worked on a concise, clear, get-to-the-point writing style, that is different from story writing, and different from argument writing.  We have worked on shortening our sentences, but using several short sentences in a row to get across a complex point.  We have worked on coming right out and saying what needs to be said, with specific detail, but without too many extra words, and without introductory phrases that don't say much.  Some students began the year with run-on sentences that included up to seven commas.  They are learning to break apart complex sentences, and achieve a clean, crisp, concise style.  Others started with such "concise" writing, that they left out most of the important detail that needed to be described.  They are writing less vaguely now, with more specific terms, and fewer missed details.

I am so pleased with their efforts!  The difference in their writing from the beginning of the year to now, is truly inspiring.  They get many comments on their papers from me, and often feel somewhat overwhelmed. However, the improvements in the quality of their informational writing on the whole should make each of them very proud.

Our genetic disorder essay is currently in its third revision.  Still to come, is the writing of a narrative story about a patient (fictional but realistic) who has the genetic disorder they wrote about.  I will be looking for connections to their research, but also a sensitive, dramatic and realistic portrayal of the real life issues that face patients and families with these genetic disorders.

Happenings in the Spanish Room

Despite the cold weather, eighth graders ushered in la primavera with Cascarones. Cascarones are confetti-fillled hollowed-out eggs that you crush on top of somebody's head.  This tradition, already popular in Mexico, is expanding to other Latin American countries.  Cascarones often appear during Carnival celebrations, Easter, Halloween, Cinco de Mayo, and even during weddings.  Having an egg cracked on your head is said to bring good luck.  Whether or not this is true is open to question.  However, I can tell you that it did create a colorful trail of confetti leading from the ball field to the classroom.

Eighth graders will be starting their final unit of study next week.  The focus of this unit will be on leisure time activities in Spanish-speaking countries.  Discussions about Hispanic art and music will be an integral part of this unit.  During the week of June 2-6, eighth grade Spanish students will take a final exam.  This is the same test that is given to all level I students in the region, including those at the high school.  It covers the material studied this year and is a requirement for any student entering Spanish II.

Sixth and seventh grade Spanish students are working on an interdisciplinary project combining technology skills and Spanish.  Mrs. Nelson introduced the students to the project via a catchy "Billy, la Bufanda" video on YouTube (see the blog entry below).  Students are preparing the animation under the guidance of Mrs. Nelson and will work on the Spanish narration during our class time.

Seventh graders will start their final unit of the year - FOOD!  We'll talk about the traditions surrounding food in various countries and compare the eating habits and diet of various Spanish-speaking countries to our own.  There will be some opportunities to sample different dishes created in and out of class.  Seventh graders are also required to take a final exam.  This test is actually the mid-term exam that is given to level I Spanish students at HVRHS in January.  Review will take place during the week of June 2-6;  the exam will be administered the following week.

On the Tuesday before vacation sixth graders traveled to Kent.  There they participated in a Zumba workshop.  Under the tutelage of Wanessa, a vivacious instructor who hails from Brazil, the students learned multiple Latin American dances.  We also learned a bit about the history of the salsa, cumbia and merengue.
The favorite dance among the students appeared to be the Capoeira, an interesting blend of Brazilian martial arts, music and dance.  A special shout out to Juan, Haley, Luke, Lucas and Arieh who boldly stepped forward to lead the class in the dance.  Wanessa was quite impressed, and so was I!  A special treat for me was listening to Juan as he conversed so beautifully in Portuguese with Wanessa!

I'd like to take advantage of this forum to recognize Roxy (grade 8) who has been very generous with her time.  Not only does she help in the Spanish room with the first grade during her Flex time, but she also assists me with a Pre-K Spanish class that meets after school.  Roxy's patient, thoughtful manner coupled with her knowledge of young children and Spanish, have made her a valuable asset in the Spanish room.  Muchas gracias Roxy!
