Sleeping? No! That's what a teenager would say if u asked them. There are lots if kind of dreams. There are fantastical, boring, weird and a lot more. No one actually knows why we are dreaming, but some dreams can be related to studying something new. Scientists made new studies, in a connection between sleeping-time dreams are better memory in people if they learned something new. So just practice, practice, practices, and start sleeping on it. :) (WARNING: This doesn't mean you’re allowed to sleep during class!) In this study 99 college student the age of 18-30 each spend an hour trying to figure out the virtual maze. This maze was hard every time they had to start in a different place each time they tried. They also had to picture of a tree and remember where the saw it. There was a 90 minutes of a five-hour break, one half of the college student was told to take a short nap, and the other half was told to stay awake. The students that were awake were told to tell what’s in their thoughts. The other group of people was asked what was there dream before and after the sleep. The scientists wanted to know about NREM ("rapid eye movement"), or non-NREM, what happens during REM sleep. This time of sleeping usually bring weird or bizarre dreams to the sleeper, even though dreams can happen in all two modes of sleep. Four out of 50 people said that there dream was connected to the maze they did before. Some dreams were about the music that was played when they were working on the maze, and others were seeing people in the maze. When the 4 people tried the maze again after the nap they were able to the tree faster than before. One of the scientists thought the dream doesn't help to learn. He said that it's the other way around. All 4 of the people who dreamed about the maze did very poorly for the first time.
This is a blog for Science Class. I will put most of the things I will do here.

Antarctica warms, which threatens penguins
Do you like penguins? If you do then I have a bad news for you. In Antarctica the temperature is going up, and that’s not good for penguins. Scientists these times they are studying the climate because it changes too often there. But, at the South Pole and Lake Vostok it’s getting colder and not getting warmer. A group of scientist looked more into the data where they found this information, some of the data went back 50 years, so they decided to estimate of temperature and make a new data table the new data table showed that West Antarctic Ice Sheet has been warming. This place takes up about one-quarter of the whole continent. West Antarctica is warming about 0.17 degrees Celsius per decade. East Antarctica had cooled slightly between 1957 and 2006 but now it’s warming up. Drew Shindell said “The new results … indicate that there’s warming related to greenhouse gases on all seven of Earth’s continents” Melting ice can easily make disaster for the continent’s wildlife. A data of gathered at a penguin rookery showed that when sea ice was average of 11% the penguin population was really bad. At that time the penguin population was half of the normal. Even if the melting slows the population will be the same. Other research showed that Terra Adélie can only host 400 breeding pairs by the end of the century. Forty years ago there was a big different, it was 15 times as now.

Living Things and the Environment
Now, search for and embed a video showing a living thing in its environment. What would happen if we took away one or more of the living or nonliving factors in its environment? Which factors could they survive without?
Look at (at least) two of your classmates blog posts. Respond to them in their comments section under their post about either their answers to the questions or the video they have posted. Email me the names of the classmates who you respond to.

KWL: Living Things
- I know that a living thing have to have cells
- It have to excrete waste

Goals for Science Class
- I don't want to have late works.
- I want to know more about Science.
- I want to do better Current Events.
- I wanna be more organized then last year with my notebook, because last year my note book was so bad.
