Astronaut symptoms

Yesterday in Science class I learned what happens to an astronaut in space.

Normally, gravity pulls blood to your legs. But in space the blood is not pulled to the ankles, legs and feet. It is free to flow wherever. A lot can go to the face.

We decided to try this out ourselves. You can see the differences after and before.

To do this lay down and elevate your feet and relax. Blood will flow from your legs to your head. Your eyes will be glassy. Notice no wrinkles when the face is full.

Astronauts also have other things happen to them in space. Muscle deteriation and bone deteriation can happen after just 6 days. It will take some time back on earth to get
everything back to normal, this is why astronauts need to exercise. If an astronaut doesn't exercise properly their bones could never recover.

On Friday I learned about Hitler.

He was great at rousing the emotions of the German people. He convinced them that the Jews were at fault for Germany's problems. He was viewed as a god. His assistant used only positive propaganda to inspire the Germans. He made a program kind of like the boyscouts to desensitize the children so they wouldn't have any compassion for the people they were killing. In the Hitler youth organization they brainwashed the kids to believe what hitler was promoting. The girls also had an organization. They danced and did artistic things which they enjoyed. They learned to cook and clean and become good mothers.

Not all the youth believed what Hitler was selling. There were several groups who met at night to come up with ideas for anti-nazi propaganda. Some groups just wanted to be like English teenagers listening to music from America and dancing during the nighttime.

But most of the people who heard Hitler in Germany fell in love with his ideas. He was truely a smart speaker. He got Germany on his side.

He was mostly a very bad person. He wanted to create the master race. Blond hair and blue eyes were the best features a person could have. He wanted to make a race of only tall and attractive people. He preached that he was mostly Ayrean (the master race), but he didn't look like the typical Ayrean. The other races were meant to serve the master race in his eyes. Even lower than that race was the "Sub-Humans" which included Jews. He wanted to kill them. He had Dr. Josef Mengele perform expieriments to improve the Ayreans.An example of an expieriment is injecting acid into peoples eyes. Dr. Mengele got away to South America where he lived until the 1980's.

Today in school...

Today I learned how to make a cloud in a jar.

  1. Fill a quart jar about 1/8 full of warm water

  2. Light a candle and blow it out inside the jar to trap the smoke.

  3. Hurry and close the jar up with the lid, but make sure you have trapped some smoke

  4. Place some ice on top of the lid

  5. Wait for 3 minutes

  6. Slowly open the lid, you should see a cloud.

How it works:

The warm water rises as the cold air on top sinks. It condenses on the smoke, which is the condensation nuclei. It is impossible for condensation to take place with out condensation nuclei. This happens in our atmosphere. The condensation nuclei in our atmosphere is dust particles. Now you have a cloud.

Pretty cool or not? If not , it was still the coolest thing I learned in school today.
