Critiquing a Classmate’s Post

I am going to constructively criticize one of my classmate’s post. The post is called Physical and Chemical Changes. This is the post :

There is a difference between a physical and chemical change. A physical change is a change that does not result in a new substance like a broken vase. A chemical change is a change that results in one or more new substances like burning wood.

I think this post is good because it is an accurate description of Physical and Chemical Changes. However, it is a little too short to be a real summary or paragraph. It is also good that the author used an image along with image credits. I found no spelling mistakes and no grammar mistakes, but one punctuation mistake : The author should’ve put a comma after the word “substance”, both times. The author seems to be an expert at science, and I would show this post to people who need to know about Physical and Chemical Changes, and who also don’t want to read a long essay.

Putting on a Happy Face

In this week’s Be A Mensch, we are learning about Sefer Panim Yafot, putting on a happy face. We were supposed to, with our family, fill out some questions as homework. One of the questions was : “When do you want to try ‘putting on a happy face’?” I said I want to try putting on a happy face in the morning. Then, Morah Liat and Morah Eta said that they wanted us to put on a happy face in a situation where you usually wouldn’t and write about it. Well, this morning I put on a happy face when I woke up, something I usually don’t do. When do you try to ‘put on a happy face’?

Don’t worry : be happy!




My Best Post of the Year

I am here to critque one of my posts, The Jew who did his Share- Einstein. I have chosen it becuase I think it is an accurate biography of the life of Albert Einstein. I believe it was my best post because it has correct grammar and spelling, and it uses a picture.I worked a LONG time on it and am very proud of it. I think I could improve my posts in the future by reading it out loud before publishing it. A goal I want to achieve is getting 100 posts before the summer. Here is The Jew who did his Share :

Albert Einstein the Jew.

You probally heard of Albert Einstein. He was the smartest man in the world, discovered E=Mc2………and a Jew!

Albert was born on March 14, 1879 in Wurrtenberg, Germany. When Little Albert was 6 weeks old, his family moved to Muinch.  He started a Catholic school (they weren’t observant Jews) at age 5. When he was 8, he transferred to the Luitpold Gymnasium. He showed an intrest in mathmetics as a kid.  When his family moved to Italy, Albert had to stay behind to finish school.

In 1902,Einstein and his future wife had a kid, who they gave to an orphanage. He married Mileva Maric in January 1903. Their two sons, Hans and Eduard, were born 6 years apart. They divorced in Febuary 1919. In June 1919, Einstein married Elsa Lowenthal, who died in 1936.

He was awarded a PhD from the Universty of Zurich on April 1905. Einstein was recognized as a leading scientist in 1908. He was also promoted lecturer at the University of Bern. He  quit the job the same year to go to the University of Zurich. In 1919, a man confirmed facts that Einstein discovered, which made him famous. He got a Nobel Prize in 1922, and Einstein was awarded the Copley Medal in 1925.

He eimgrated to the U.S. as soon as Hitler came to power. When WWII started, Albert Einstein warned President Roosevelt that Germany might be making atomic bombs. Roosevelt put him in charge of the Manhattan Project, the one that created the atomic bomb.

Einstein took a job at the Institute of Advanced Study in Princeton, which he held until his death. In May 1933, the Nazis burned his books and works. He discovered he had a reward of death for $5,000 dollars, nowadays worth $90,000.   When other scientists from Germany fled to America, he wrote “I have never felt so Jewish.” Einstein, with other immgrated scientists, warned the U.S. that Germany might  build the atomic bomb, but the first time his warnings were ignored.

He became a American citizen in 1940. In 1952, David-Ben Gurion asked Einstein if he would like to become the Prime Minister of Israel. Albert refused, saying that he “lacked the apitude and experience to deal properly with people and to exercise offical functions.”

On  April 17th, 1955, an internal organ inside Albert Einstein’s body exploded. He didn’t want to have surgery, saying that “  It is tasteless to prolong life artificially.” He also said that “I have done my share.” He was working on scientific papers the next morning when he died at 1 AM. He was cremated the same day, but scientists kept his brain in hopes of discovering what made him so smart.

One of the greatest  people in the world was from a religon that was hurt the most. Just goes to show that it matters by how the personality is, not what color or what language they speak. What matters is how they act.


How Organisms Compete and Survive in an Ecosystem

         Organisms in one ecosystem are called populations. Populations living with other populations are called a community. Another part of ecosystems is the physical environment, which could be the sun, air, water, weather, and dirt. Populations interact with the dirt and sun and water. But to live, each population needs a specific amount of this stuff. The need to get these things leads to competition. To compete in habitats, animals have adaptations.

          Sometimes different populations relate with each other, which is called symbiosis. One kind of symbiosis is called mutualism, where both organisms are helped. Another kind is called commensalism, where one organism benefits and the other isn’t hurt. The last symbiosis is called parasitism, where an organism thrives whiles the other is affected. To survive, prey have to killed by predators (meaning that animals have to be killed). As it is easy to know that predators need prey, it is harder to see that prey need predators. But they do, because if predators would be taken out of the food chain, then the prey would get bigger, and then starve because all the food would be eaten.

    A human population is like a neighborhood or town. But a animal population is a group of animals living in a habitat. A animal community is lots of groups of animals living in, say, a savannah. A human community is a county or state. Also, human competition is when humans and animals fight over land and trees. Animal competition is over water or food.

Turning Ten

On January 3rd, I turned 10! This is especially special to me since I am the youngest in the class. I am going to have a pirate sleepover party. I LOVE pirates, especially POTC. I am inviting Ethan, Justin, and Noah. We are going to wear costumes from Pirates of the Caribbean characters. I am going to be Captain Jake Sparrow (since my name is Jake). I gave all the foods pirate names. For example : pizza- privateer’s prize food. We are going to eat green apples instead of brushing our teeth. We also have to talk like a pirate the whole time. I’m so excited about my birthday!

Happy New Year!

Happy new year to everybody out on the WWW! Now its 2012, I can’t believe it! What is your new years resolution? Mine is to stay on patrols and Knesset. Its also to make an impact in Knesset, because I want to make the year better. I hope to get to 1,000 visitors and 100 posts. This is my 66th post, and right now I have 701 visitors. Thank you to all the commentors and visitors, and I hope that you’ll do the same in the new year!
