Weather Fronts

Cold Front: The cold front moved in quickly and and pushed against the warm air creating clouds and then from the clouds came precipitation.

Warm Front: The warm front moved in slowly and created cumulus clouds and cirrus clouds above the cumulus clouds and then it precipitated.

Stationary Front: A cumulonimbus cloud was created when the warm and cold air met in the middle and that caused precipitation.

Occluded Front: The warm air got caught between the cool air and that caused a cumulonimbus cloud and then came precipitation.

London-Type Smog

One hundreds years ago in London, England the people burnt coal in factories and houses. This caused the air to be polluted with soot and smog. London-type smog forms when particles in coal smoke combine with water droplets in humid air. Today people in London burn alot less coal, therefore the air in London is much cleaner than one hundred years ago.

Earth's Atmosphere

Unlike the moon Earth as a very protective atmosphere. Earth been impacted by the same amount of meteorites as the moon , but Earth has an atmosphere so the crater washed away in a short time. On the moon though a crater can stay on the surface of the moon for 4 billion years. Earth's atmosphere can also keep heat in it and keep heat out which makes it possible for humans to live on Earth. The ozone layer protects Earth and the life on it from ultra violet rays. The moon can't keep its own heat in or out without an atmosphere so the temperatures on the moon are very extreme. Earth can also hold gases in its atmosphere. This makes it possible for human existence. Earth's atmosphere is suitable for living things it can hold in gases and heat, therefore it is different from the moon.

Space Exploration

Space Exploration

The Science Of Rockets
Since the late 1950's NASA has used Atlas rockets. With Atlas rockets NASA is able to launch probes into space and satellites into orbit around Earth. Atlas rockets have been used in many missions for governmental and commercial enterprises.
The Space Program
NASA or The National Aeronautics and Space Administration began in 1958. Apollo 13 was launched on April 11, 1970and only spent 6 days in space. Instead of space rockets they launched probes into space.
Exploring Space Today
A new type of small robot for the International Space Station is called a personal satellite assistant floats next to an astronaut. The robot is powered by solar cells. The robot has not only camera and light but also a videophone.
Using Space Science On Earth
NASA says less than 1 percent of the U.S. budget is spent on the space program. NASA stresses its contribution to the country's economic welfare because many people think the funding should go towards education or medical research.

Phases, Eclipses, and Tides

Gizmo Summary

Based on my observations the two factors that cause seasons are the tilt of Earth's axis and revolution. The revolution of the Earth causes seasons because as it revolves around the sun the axis points in different directions. So one hemisphere is getting more direct sunlight than the other therefore it is warmer or cooler in one hemisphere then seasons are caused. The seasons in the two hemispheres of the Earth are always opposite. The tilt of Earth's axis causes seasons because the tilt makes one hemisphere receive more direct sunlight. In conclusion the tilt of Earth's axis and revolution of Earth around the sun cause seasons.

Perspective

The book Zoom by Istvan Banyai is a really cool book. I have never seen anything like it. Zoom just has pictures and on each page there is a bigger picture. It challenged my mind to make inferences about what would be on the next page based on what was on the page before.



Zoom changed my perspective almost every page. The first thing I saw was a red jaged picture and I thought it was the sun. But then the page turned and it was a rooster head. Each time the page was turned there was a bigger and a differrent perspective. My perspective changed rapidly throughout the book.

Scientists have to look at data from all different angles, depths, and perspectives to understand it. For example scientists study space close up and far away. To make sure you arent revealing false information you have to look at every detail and research about prior information. Stars look like little lit up dots and planets look like brighter stars from Earth however in space planets are incredible masses. We have discovered what we know about space from science.

Enigma Box

Scientists use skills like classifying, inferring, observing, predicting, and making models. During the enigma box activity I used scientific skills. I observed what was happening with the water going in the box and coming out. I also inferred what was going on inside of the box. After that I made a model of how the box actually looked inside.

While my teacher poured the water into the enigma box I observed that the box had a big hole and a small hole in the top of the box. On the bottom of the box there was a small tube. My teacher continued pouring the water as she poured water dripped out of the small tube in the bottom. When all the water was in the box the water started rushing out of the tube. This is what I observed from the enigma box.

What's on the inside of the enigma box? I think there is a spiral tube inside of the enigma box. When the tube is full all of the water just rushes out, but it drips until it's full.

The box actually has a tube inside of it. The tube is looped and one side goes outside of the box. When water fills the tube to a certain point it flows out of the tube that is outside of the box.
