Cool Site For Middle Schoolers

I found a site that can be useful to middle schoolers. It is known as http://www.Chem4kids.com . It is an interactive, educational and fun site. It is also a colorful site. Andrew Rader sponsors this site. This site has lessons and quizzes about science topics. It also has test resources and related links to other websites(geography4kids). These related links are at the bottom of a lesson. Also, the site has a link to math lessons. This site provides basic information about any science topic(ex. matter, biology, atoms). At the bottom of the page there is a google search tool where you can type in what you want to search/find. There are some positive and negative aspects about this site:

Positive Aspects:

* you can learn about different science topics

* there are quizzes and tests you can take

* about 20 questions for a quiz, more than 35 questions for a test

* experiments that you can try out

* you can prepare for the NJASK, GEPA, CTY for John Hopkins, assessments in school

Negative Aspects:

* one paper per lesson /topic

* there are no project ideas

* only one test or quiz for a topic

This site has a lot of uses. Students can prepare themselves for the NJASK, GEPA, CTY for John Hopkins, assessments in school. Teachers can look at this site and get ideas for lab experiments. Students can get homework help from this site. Students will learn basic information about science topics. Also, the website launched a new math link. You can get practice from reading the lessons the website gives and doing their tests. I would recommend this website, because there are soooo many uses.

Bizarre Catastrophes Happening in the Universe

WHAT'S GOING ON IN THE UNIVERSE!

There is the latest news about our universe which is bizzare, but true. http://www.foxnews.com/story/0,2933,322254,00.html has the latest story. The site I got the story from said, and I quote " Huge clouds of gas, galaxies all crash into each other, rip each other apart--- but over millions of years. The deeper astronomers gaze into the cosmos, the more they find it's a bizarre and violent universe." Reseachers had a meeting where they talked about "baby" stars to "rogue" black holes. As you can see, one topic that was mentioned was about black holes. The odds of one of these black holes swallowing up Earth or the sun is somewhere around 1 in 10 quadrillion in any given year. One researcher had presented her theory about these black holes. She says," It's an odd universe we live in. No one should be worried about these black holes. " Scientists are finding that not only are they improving their knowledge of how did this all start and where is it all going, they also are running into hard-to explain, cosmic quirks( An unpredictable or unaccountable act or event). At the meeting, scientists also talked about an approaching gas cloud. The scientists say and I quote, " The cloud has a mass 1 million times that of the sun. It is 47 quadrillion miles away. But it's heading toward our Milky Way galaxy at 150 miles per second. When it hits, there will be fireworks that form new stars and "really light up the neighborhood. But don't worry. It will hit a part of the Milky Way far from Earth. The giant cloud has been known for more than 40 years, but only now have scientists realized how fast it's moving. It is moving so fast that we can see it sort of plowing up a wave of galactic material in front of it." Astronomers unveiled a giant map of mysterious dark matter in a supercluster of galaxies, they explained that the violence of the cramped-together galaxies is so great that there is now an accepted vocabulary for various types of cosmic brutal behavior. The gravitational force between the clashing galaxies can cause "slow strangulation," in which important gas is gradually removed from the victim galaxy. "Stripping" is a more destructive process in which the larger galaxy tears gas from the smaller galaxy, "harassment," which is a fast fly-by encounter.

Because of this discovery, I am more interested in space and astronomy. The universe is awe-inspiring!!!!
