Earthquake, Volcanoes, and Tsunamis

Hello reader in this science class we are learning about earthquakes, volcanoes, and tsunamis. It sounds very fun and interesting. I can't wait.
    Earthquakes are caused when the two fault lines get stuck and can't move. They also happen when the earth has to much forces. The forces push and pull the rock beneath the earths surface. These are the things that can cause an earthquake.
   Volcanoes are vents, and they are also openings in the earth. Volcanoes are also like mountains that can erupt. A volcano can be a mountain that shoots very hot lava. It can destroy almost anything with it's steaming hot lava.
   Volcanoes change Earth's surface because when they erupt it's steaming hot lava destroys homes, cars, islands, and other things. It can also destroy are body, and that is a very dangerous thing. It changes earth's surface because it destroys our mother earth. It destroys it because it effects the earth by how it harms it.
   What determines a volcano is by how it shoots it's lava. Volcanoes can cause the rock beneath earth to change from a solid to a liquid.

The Nervous System

Hello Readers,

In science we are learning about are nerves. This is an important system in are body.

    The nervous system is important because it is the most thing that helps us. My brain revives information by what you eat and by what you do. There are also nerves that send the food, and the information to your brain. This is how your brain gets information from outside the body. Are body works with are muscles by helping it do things. The things it helps us do is eat, move, and do more things. Are brain works with are involuntary muscles by controlling are nerves. Are nervous system controls our muscles. Those are the muscles that can move with out you even thinking.

Soil Sample

My soil sample is a solution because I was trying to find how much it would weight.

Working as an Scientist: Web Quest 1

My soil sample is a mixture because I could see chex mix and skittles all mix in a bag. I do think my soil sample is a mixture.
       Before I continue to tell you about my experiment, I want to share with you some information that might be helpful. Matter comes in three different states. Those states are, liquid, solid, and gas. Matter also has different properties. Those properties are volume, mass, shape, and color. The two properties that of all the states of matter have in common are mass and volume. Mass is the amount of matter in an object. I learned this by using discovery education science tech-book. Mass is not the same thing as weight. Weight measures the force of gravity on an object. Mass is measured using a balance or a scale. The unit of measurement for mass is the gram. The mass does not change with change of location. However, the weight of an object does change, this is because the force of gravity changes, For example, the gravity on the moon is different than the gravity on Earth. A baseball will weight different on the moon than it does on Earth. However, the mass remains the same because the ball is still made up of the same amount on matter.
          Now that you have some background information lets get back to talking about my soil sample analysis. As I said earlier, I am an environment scientist. I collected a soil sample from a construction sight and analyzed it using the following process:
        1. I collected the soil sample.
        2. I found the mass of the entire soil sample using a scale.
        3. I seperated the contaminents from the soil
