UNIT B - ELECTRIC CIRCUITS´WORD PROBLEMS


If it wasn´t clair what is a parallel and a series circuit here is another video about how can you apply it to a word problem as we are seeing in class but without values,we search the relationship and then we have to draw the electric circuit as many times as we need .I though it would be a good idea see in a video that introducing values in the relationships we get in class ,we should get the same.So the Don Jesús method is really good because you can apply it in other word problems in the future,you don´t need any values.

UNIT B - ELECTRIC CIRCUITS´WORD PROBLEMS

Here is another video about electricity in general,but also about the electric circuits .                                  
It is a video for children that´s why i liked because it explains many concepts in an easy way but also really  interesting.It can be useful to see a practical application of electricity and also the electric circuits.               
I hope you will like it.

UNIT B - ELECTRIC CIRCUITS´S WORD PROBLEMS

Here is a video you can use to make contrasts between a parallel circuit and a series circuit.                                  I thought it would be interesting to see this ,to improve in the solving method we use to do the word              problems.So it is an easy way to understand it much better because if we don´t know what is a parallel         or a series circuit,we have a great problem to do large word problems.                                                          I hope you will like it and that it will help you a lot.

UNIT B -ELECTRIC CIRCUITS. WORD PROBLEMS

Here is another video about how to solve electric circuit´s word problems in an easy way if someone didn´t understand it very well.I liked this video because it shows 7 tricks or the steps(step by step)of how to solve difficult problems in an easy way. The only difference is that they use numbers and not only the relationships ,but the process is the same.                                                                                                                        
I hope you will like it because it can be useful.

UNIT B - ELECTRIC CIRCUITS WORD PROBLEMS

As we are doing in class know (doing word problems),we have to calculate the voltage ,the amperage but also the resistance in which we have to use our brain a little bit more because we have lots of data and we can make a mistake really easy.
So i found a video about the resistance in a series circuit can work but also how you can get out the value in a word problem.I think it is really good to understand the resistance mechanism in a electric circuit.
I hope you will like it.

UNIT B.-ENERGIES

Then here is another video which explains in detail all the types of energy( 7 types but there are only 8) but it is good to know a little bit more of energies before start to investigate about it.
I hope you will like it because it is really good because of its quality and presentation of the topic(energies)





                 

UNIT B.-ENERGIES


Before start with the unit of energies i thought that it was useful to know what are the energies to have a base about this topic so it will be good .
I liked it because it contain information  from the beginning to the end and it explains it with images.
I hope you will like it.

OTHER-CHRISTMAS


Here is an interesting video about a Christmas Tree established in Mexico City which was 110.35 meters, which corresponds to the height of 40-storey building, and the diameter - 35 meters. Total weight of all metal structures was 330 tons, It is made of steel rods and wire, but consists mainly of electric garlands - 1.2 million colored lights and 80 miles of wires.Now it is on the Guiness book of records.
This video shows it:

OTHER - NEW YEAR´S EVE

Early New Year's Celebrations

The earliest recorded festivities in honor of a new year’s arrival date back some 4,000 years to ancient Babylon. For the Babylonians, the first new moon following the vernal equinox—the day in late March with an equal amount of sunlight and darkness—heralded the start of a new year. They marked the occasion with a massive religious festival called Akitu (derived from the Sumerian word for barley, which was cut in the spring) that involved a different ritual on each of its 11 days. In addition to the new year, Atiku celebrated the mythical victory of the Babylonian sky god Marduk over the evil sea goddess Tiamat and served an important political purpose: It was during this time that a new king was crowned or that the current ruler’s divine mandate was symbolically renewed.
Throughout antiquity, civilizations around the world developed increasingly sophisticated calendars, typically pinning the first day of the year to an agricultural or astronomical event. In Egypt, for instance, the year began with the annual flooding of the Nile, which coincided with the rising of the star Sirius. The first day of the Chinese new year, meanwhile, occurred with the second new moon after the winter solstice.

January 1 Becomes New Year's Day
The early Roman calendar consisted of 10 months and 304 days, with each new year beginning at the vernalequinox; according to tradition, it was created by Romulus, the founder of Rome, in the eighth century B.C. A later king, Numa Pompilius, is credited with adding the months of Januarius and Februarius. Over the centuries, the calendar fell out of sync with the sun, and in 46 B.C. the emperor Julius Caesar decided to solve the problem by consulting with the most prominent astronomers and mathematicians of his time. He introduced the Julian calendar, which closely resembles the more modern Gregorian calendar that most countries around the world use today.
As part of his reform, Caesar instituted January 1 as the first day of the year, partly to honor the month’s namesake: Janus, the Roman god of beginnings, whose two faces allowed him to look back into the past and forward into the future. Romans celebrated by offering sacrifices to Janus, exchanging gifts with one another, decorating their homes with laurel branches and attending raucous parties. In medieval Europe, Christian leaders temporarily replaced January 1 as the first of the year with days carrying more religious significance, such as December 25 (the anniversary of Jesus’ birth) and March 25 (the Feast of the Annunciation); Pope Gregory XIII reestablished January 1 as New Year’s Day in 1582.
New Year's Traditions
In many countries, New Year’s celebrations begin on the evening of December 31—New Year’s Eve—and continue into the early hours of January 1. Revelers often enjoy meals and snacks thought to bestow good luck for the coming year. In Spain and several other Spanish-speaking countries, people bolt down a dozen grapes-symbolizing their hopes for the months ahead-right before midnight. In many parts of the world, traditional New Year’s dishes feature legumes, which are thought to resemble coins and herald future financial success; examples include lentils in Italy and black-eyed peas in the southern United States. Because pigs represent progress and prosperity in some cultures, pork appears on the New Year’s Eve table in Cuba, Austria, Hungary, Portugal and other countries. Ring-shaped cakes and pastries, a sign that the year has come full circle, round out the feast in the Netherlands, Mexico, Greece and elsewhere. In Sweden and Norway, meanwhile, rice pudding with an almond hidden inside is served on New Year’s Eve; it is said that whoever finds the nut can expect 12 months of good fortune.
Other customs that are common worldwide include watching fireworks and singing songs to welcome the new year, including the ever-popular "Auld Lang Syne" in many English-speaking countries. The practice of making resolutions for the new year is thought to have first caught on among the ancient Babylonians, who made promises in order to earn the favor of the gods and start the year off on the right foot. (They would reportedly vow to pay off debts and return borrowed farm equipment.)
In the United States, the most iconic New Year’s tradition is the dropping of a giant ball in New York City's Times Square at the stroke of midnight. Millions of people around the world watch the event, which has taken place almost every year since 1907. Over time, the ball itself has ballooned from a 700-pound iron-and-wood orb to a brightly patterned sphere 12 feet in diameter and weighing in at nearly 12,000 pounds. Various towns and cities across America have developed their own versions of the Times Square ritual, organizing public drops of items ranging from pickles (Dillsburg, Pennsylvania) to possums (Tallapoosa, Georgia) at midnight on New Year’s Eve.

OTHER-CHRISTMAS LIGHTS IN AMERICA

Here is a video about the use of lights in Christmas,especially in America because for many families in the United States, taking a drive to see local light decorations during the Christmas holiday is an annual tradition. One of the most spectacular in the Washington area features more than one million lights. VOA's Deborah Block takes us to dazzling displays at Watkins Regional Park in Upper Marlboro, Maryland.
I hope you will like it.
