Digestive System

   I found my picture HERE.

You have all kinds of of body parts and when you eat there is a process called the digestive system. The digestive system is where the food goes to one place then goes to another place and all of the healthy stuff stays in your body because you need the stuff but all of the unhealthy stuff doesn't stay in your body. When you take a bite and swallow it, it goes down into your esophagus then goes to your stomach then it goes into your small intestine into your large intestine then all of the stuff your body needs stays in your body but the gunk that doesn't belong in your body comes out.

I found my info HERE and HERE.

What Causes Gravity?

I have been researching about gravity and it said that gravity is one of the four fundamental  forces of the universe and is considered a non-contact force. The first person to describe it were people could understand what gravity was, was Isaac Newton. Isaac Newton used the universal law of gravitation to describe how gravity works. He gave the foundations of physics. The greater the mass and the closer the two objects are, the stronger the force of gravity. Also Isaac Newton was the first person to find out what gravity was. After Isaac Newton found gravity Albert Eisenstein came along and  he stated that gravity was simply a curvature in space-time created by a mass object pretty much in the same way a piece of cloth would be curved if it was stretched out and a heft object was placed on it. Other people who studied gravity are...Henry Cavendish, Stephen Hawking, Galileo Galilei, Pierre De Fermat, and Christiaan Huygens.

John Dalton

John Dalton

        John Dalton is the man you can thank for chemistry class. He came up with a theory that all gases can be turned into a liquid. He said that with low temperature and high pressure that a gas can become a liquid. In 1803 he published the Law of  Partial Pressures which is used by every college chemistry student and more. Dalton grew up as a great man with a hard and limited education. Dalton was born on September 6, 1766, in Eaglesfield, England. Both of his parents were Quakers.Dalton grew up as a great man with a hard and limited education. Even though they were Christians they were seen as dissenters which made his education hard. Although he was once a principal after he started teaching himself mathematics, Greek and Spanish. John Dalton made a change in how we see gases.

Wind Power

   Have you ever been driving through the middle of nowhere on a long road trip and seen some huge spinning fans? Those are windmills (wind turbines). Windmills harness the wind to generate electricity.

   The turbines usually have three main parts.
       1. The Stem (The pole that connects to the ground)
       2. The Rotor (The part that spins with the blades on it)
       3. The Nacelle (The gearbox with the generator inside)

   How they work: One of my sources said "A wind turbine works the opposite of a fan. Instead of using electricity to make wind, it uses wind to make electricity."  The flowing of wind makes the transmission spin to make the generator turn to make power.

   Wind is a very green source of energy and I hope that more people in the world can use it.

Hydraulic machines

For Christmas my cousins gave me a hydraulic machine set. Hydraulic means run by water. A few days after Christmas we used the kit and made hydraulic judo bots. It took a few hours to make them but we finally did it. After we made them we spent hours using them to fight the other robots. Next time we have 4th grade class I will bring two hydraulic robots with me and explain how they work (maybe only one). We used a website called instructables.com. This website tells you how to make a lot of hydraulic things and other experiments.
