FATHER MOON:
Lunar Myth: Father Moon
o Yasi had a son. One day the boy was playing with a jaguar and was accidentally killed. The jaguar was terrified and ran deep into the forest to hide forever. Yasi wanted to find out who the killer was, but none of the animals would tell him. This so enraged Yasi that he gave the howler monkey a long neck, put spines on the porcupine, and burdened the tortoise with a heavy shell.
Myth Cont.
o Yasi was still furious, so he leaped into the night sky to search for his son’s killer. He searched all across the land and the sky. Each day Yasi got dirtier and dirtier until he was completely covered with soil and leaves. He stopped by a stream to clean himself and rest. Each day he rested, Yasi washed a little bit off his face. Finally he was completely clean, and he resumed the search for his son’s killer.
Myth Cont.
o Yasi is still wandering the skies today, spending half his time hunting and half his time resting. When he returns from the hunt, his face is completely covered in dirt. He washes off a little of the dirt each day until his face shines brightly once again.

7th Grade Benchmark Review for Friday November 12, 2010
1- Please review your notes from class on Gravity. Gravity is a force. When I push down on you that is force being exerted on you. Your mass or the mass of any object is what it is made of. The mass doesn't change even if gravity changes. If you are on a space ship to Mars, your weight will decrease because gravity decreases. Your mass will remain the same.
2- If I throw a rock in the air and it falls, which it will, that is an example of gravity. Me pushing a car on a table is not, and neither is someone driving a car on the highway. An apple falling from a tree is also an example of gravity. Falling, anything falling is an example of gravity.

3- What causes the gravitational force between the Sun and the Earth is their masses. As mass increases so does the gravitational pull between them, but as the distance increases, the force decreases.
4- Larger planets have greater relative strength when it comes to their gravitational pull. The reason you weigh less on the moon is because the moon is smaller and thereforce has a smaller gravitational pull than the EARTH.
5- Once you are outside the Earth's Atmosphere gravitational pull decreases. Remember what I mentioned in class. For only $250,000 you can take a special plane into space, just outside Earth's atmosphere and float around.

6- Your weight on Earth is the force gravity imposes on your mass. It is related to your mass, not your volume.
7- Review why NJ is warmer in the summer. Recall it is not the distance but it is the ANGLE at which the suns rays hit us. SOLAR Angles.
8- In the winter the sun in the sky is the shortest.

8th Grade BenchMark II test on Friday November 12, 2010
1- Brachiopods are marine animals with large shells. They live in Coral Reef, in the Ocean.
This is a picture of a brachiopod.2- Fossils are great assets in history. With a fossil we can carbon date and find out the age of a bone.
We can also use fossils to learn what type of animal or plant lived in a given area. For example, in the Grand Canyon it would not be uncommon to find a fossil of a cactus in the future. This would tell future generations that the Grand Canyon is dry and hot.
Apart from telling you about the climate fossils can also tell you about what types of animals lived in a given area. If you find the fossil of a fish on a sand bed, you can infer that perhaps at one time that area may have been covered by water.
3- Uniformitarianism assumes that the same natural laws and processes that operate in the universe now, have always operated in the universe in the past and apply everywhere in the universe.
4- Sedimentary rocks are the only type of rock that can contain fossils, the remains or imprints of dead organisms. In nature, dead organisms are usually quickly removed by scavengers, bacteria, rotting and erosion.
5- According to fossils that we have found do you know how old the Earth is? 4.5 Billion years. Yes that is older than I your science teacher.
6- Uplifting is nothing more than land being raised to a higher level.
In seeing the video above it's easy to understand why running water, the Colorado River, is the main method of Erosion in the Grand Canyon.
8- The Principle of Superposition states that Sedimentary layers are deposited in a time sequence, with the oldest on the bottom and the youngest on the top. In other words, oldest on the bottom and newest on top. 9- Remember the following careers:
Geologists study Rocks
Archaelogists study fossils
Botanists, study plants
10- As seen in the video above weathering is nothing more than the breaking down of rock. DO NOT confuse it with the WEATHER. It doesn't have to do with weather. A rock can break in good or bad weather.
A great example of weathering ICE WEDGING.. because it breaks down rock, not because it happens in cold weather, remember weathering can happen in ANY TYPE of weather.An avalanche is caused only by gravity, nothing else. Look at the this video of an avalanche in New Zealand. The snow accumulates until gravity eventually just pulls is down the side of a mountain.
11- What is Mechanical Weathering, breaking down rock through a physical process, but Chemical Weathering is breaking is down in a chemical reaction.
Physical weathering would be the lab where be made sand from shaking the stones. Chemical weathering is the lab where we applied the acid to the rocks and it fizzed
We will review this information in class as well and have a the Science Feud Face off for points on Wednesday, be prepared to earn points...

The above link is a discussion taking place at the Grand Canyon regarding this very topic4- Sedimentary rocks are the only type of rock that can contain fossils, the remains or imprints of dead organisms. In nature, dead organisms are usually quickly removed by scavengers, bacteria, rotting and erosion.

The above video shows and discusses fossils and sedimentary ROCKS. You only need to watch the first 2 minutes the rest is pretty advance, but entertaining if you would like to view it. (You don't have to write this statement here if you are writing it to study)5- According to fossils that we have found do you know how old the Earth is? 4.5 Billion years. Yes that is older than I your science teacher.
6- Uplifting is nothing more than land being raised to a higher level.
http://www.youtube.com/watch?v=hSPrzdW88ic (This Video Illustrates the process)
7- Erosion is moving sediments from one area to anotherhttp://www.youtube.com/watch?v=oFnpm4SUF7I
This video illustrates Weathering, Erosion and Deposition in only 60 seconds (VERY EASY TO Understand)In seeing the video above it's easy to understand why running water, the Colorado River, is the main method of Erosion in the Grand Canyon.
