Finish Strong

The students are undoubtedly excited for the summer break, but they need to successfully navigate through this final week first. Please encourage them to study hard for their exams and finish strong. They have received a review sheet.

Last Week of Algebra I

We are almost to summer! It has been a pleasure to work with all the students this year. This week the students started reviewing for their final exam. We will continue to review for the exam on Monday and Tuesday with the Final on Thursday. They should be working on their final review packet and reviewing their notes to study for the final. As this is their last weekend of the semester, please remind them that their test corrections and any late work is due on Tuesday, May 24th.

Problem #29 Solutions – 9(1+1)+6

 

Problem #30 – The Game of 24 (7, 14, 14, 18)

Problem #30 Solutions – (7+18)-(14/14)

 

Problem #31 – The Game of 24 (1, 4, 18, 24)

Problem #31 Solution – 4(24-18)*1; 24/4+(1*18)

Review Week Begins!

As we move into the final full week of classes, we will first finish up the material of Chapter 12 by completing a translation about the early Roman hero Mucius Scaevola.

After this, finals review will officially begin. Starting on Wednesday, we will spend each day going over one aspect of our Latin knowledge: nouns, verbs and case uses. We will continue to review material leading into finals week.

Work-Energy Theorem this week in Physical Science

Wednesday will be our last day for new material in Physical Science, and we will spend the next three days wrapping up our discussion of work and energy, with focus on the Work-Energy theorem. This will give the students a powerful tool to analyze kinematic systems, and indeed most advanced studies of mechanics focus not on the traditional equations of motion (which, altho valid, prove cumbersome for complex systems) but on the conservation of energy within the system.

For 10 points of extra credit, students can answer the following question:

Last week in class we wrote two formulas relating the height an object falls from and the time it takes to fall. Use a similar approach to write a formula for the work done by gravity on an object with mass m moved with vertical displacement h.

This extra credit is due tomorrow (Monday).

Julius Caesar and Final Exams

This coming week the 7th graders will finish reading Julius Caesar by Friday.  There will be two vocabulary quizzes this week:  the postponed Acts 1-2 quiz will be Monday and Acts 3-5 vocabulary quiz will be on Friday.

Each day in class, students will read assigned parts of the play and discuss questions for understanding, most of which will be assessed on the final exam on Thursday, May 26th.  Homework will focus each day this week on studying the vocabulary words and definitions.

 

The Crisis of the Third Century

Historians of the Roman Empire refer to the period following the death of Alexander Severus in 235 AD to the accession of Diocletian to the imperial throne in 284 AD as the “Crisis of the Third Century.” There were five reasons for this crisis:

  1. Invasions from Germanic barbarians east of the Rhine and north of the Danube and from Sassanid Persians to the Roman Empire’s easternmost border.
  2. The so-called “barracks emperors”—commoners, often from the outskirts of the Roman Empire, who had ascended the ranks of the military and garnered (temporarily) support from the troops—died in battle or were killed by the disenchanted troops who had put them in office. There were twenty-six emperors in this fifty year period.
  3. As a result of civil war, the Roman Empire was divided into three competing empires—the Western Gallic, the Central Roman, and the Eastern Palmyrene.
  4. Given that there had been no expansion since the reign of Hadrian (117-138 AD), the Roman Empire had lost a significant source of its income: conquest. This was compounded by the economic problems of barracks emperors being forced to pay the military to stay in power, paying off barbarian invaders, the expenses of the bread and circuses, inflation as a result of devaluing the denarius, and a decrease in trade.
  5. Plague struck in 250 AD, killing, it was said, 5,000 a day in Rome.

Finishing gravity, starting energy, work, and power this week in Physical Science

This week in Physical science we will be finishing our discussion of gravity, then moving on to the topics of energy, work, and power. In common usage energy and power are often used to mean the same thing, but in science they mean two separate but related ideas: power is simply the amount of energy per unit time. This leads to a somewhat convoluted measure of energy on your electric bill, the kilowatt-hour, which is energy per unit time multiplied by time, thus leaving energy. Work in a physics sense is perhaps the most confusing concept to grasp, since one can exert a great amount of effort but do no work: for example, carrying a heavy box across a room does no work if analyzed at a basic level of physics.

For ten points of extra credit, students can answer the following question and turn it in by Wednesday:

Who is the unit of energy named after, and when was he alive?

Julius Caesar

7th Grade Literature & Composition students will read Julius Caesar through scene 1 of Act III this week.  For each act, students are assigned a part to read aloud in class, which they are expected to practice the previous day for homework.  This may include looking up word pronunciations and practicing reading aloud to work on fluency and voice inflection.

We will have a quiz on Friday over Vocabulary for Acts I-II.  There will be no homework on Wednesday due to the Science Museum field trip.

Bravo!

The concert was a success because of the impressive effort from your children. They looked and sounded great, and they put in the work to have four pieces memorized. Concert reviews were due on May 6th. Thank you for helping your child to get to a concert. I hope it was enjoyable.

This week in class your child received a packet and questions over the Classical era. Over the next few class periods we will discuss the three main composers of that era: Haydn, Mozart, and Beethoven. As the semester comes to a close, please make sure your child cleans his or her recorder according to the directions they have been given.

 

Polynomials

Last week, the students learned how to multiply and divide all types of polynomials. This week, they will have two unusual days and then finishing up their polynomial unit. On Monday, they will be taking a readiness test for next year. Tuesday and Thursday, the students will be reviewing for unit test. Wednesday the students will be going on a field trip to the Science Museum. Friday, the students will be taking their unit test on polynomials. They will need to be able to simplify polynomials, add polynomials, subtract polynomials, multiply polynomials, and divide polynomials.
