Prompt #1: Electronics and Computers 3/24/11

Analog signals are different from digital signals because an analog signal can be made by something that has information, for example a person body temperature; it gives information about the persons’ health. An analog signal also changes very smoothly. A digital signal changes very rough. They change in bumps or steps. CD players and digital clocks are examples of digital signals. Semiconductors are useful in electronic devices because their electrical conductivity can be controlled by adding impurities. Diodes, transistors and integrated circuits are used in electric circuits.

Since almost a century now, NASA has discovered many new things around the universe. They have discovered 9 different planets, the sun and the moon. One of those planets they have discovered is called Mars. NASA workers have landed rovers on to Mars. This all could not be able to happen unless communications were sent to the rover and to the astronauts to know where they are going and what to do. Also, considering that you need electricity to even fly a space craft, none of this could have happened without it.

Bharat : I liked how you dived right into the material. I liked how you explained things with detail but when you explained them you didn't spend a whole paragraph explaining one concept which was good.

**Prompt #2: History of Rockets** 4/5/11 Period 1

=
In this reading, I learned a lot about rockets. The Chinese set a bamboo stick filled with gunpowder on fire to create explosions during religious ceremonies. Once they noticed it exploded, they started experimenting even more. Soon after, they attached the bamboo to an arrow and launched it with a bow. They realized they just needed to guide the rocket. They didn't need to shoot it with an arrow When China was at war with the Mongols, in 1232, they used this New Rocket. =====

In 1898, Konstantin Tsiolkovsky, a Russian school teacher, had a theory of space exploration by these rockets. Tsiolkovsky is the reason we have researched and learned so much about space. The moon, the sun, Earth, and now even Mars.

An American scientist, Robert H. Goddard, built the fist successful flight with a "liquid propellant' rocket on March 16, 1926. During WW2, Germany built the V-2 rocket, which was used against London in the war. The V-2 was a small rocket compared to the ones we have today though it was big when it was made around WW2. Both the US and the Soviet Union realized that these rockets were a big help as a military weapon. Both of the countries kept experimenting and making more rockets.

**5/15/11** <span style="color: #1f85e5; font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; font-size: 130%;">The nose cone helped the rockets airflow. The body tube holds the recovery system which holds everything inside the rocket. Once the rocket reaches its apogee, the recovery system (the parachute) will pop out of the body tube. The launch lug is what guides the nose cone in a straight line. The motor mount is what keeps the motor in the same place so it doesn't move and mess up the direction of the rocket. The three fins help the rocket go straight, too. If one of them fell off, the rocket would change direction. Last but not least is the rocket motor. The rocket motor is filled with gun powder which is lit on fire during the ignition.

//<span style="color: #000000; font-family: Arial,Helvetica,sans-serif; font-size: 130%;">Ms. Mc: Good job! You left out the recovery wadding (-2) and a figure # and title (-1). Your ink also shifted on your diagram. 17/20. //

<span style="color: #fd840d; font-family: Tahoma,Geneva,sans-serif; font-size: 160%;">Log Prompt #6:

What is a Quark? What types of quarks are there? A quark is an elementary particle. There are six types of quarks, known as flavors: up, down, charm, strange, top and bottom. Up and down quarks have the lowest masses of all in the universe.

What is a Galaxy? How did they form? A galaxy is any large collection of stars that can be recognized as a distinct physical object. Galaxies were formed by the Big Bang. The Big Bang, as seen in Figure 2, was the beginning of the solar system. For many thousands of years, the universe was too hot for any galaxies to be made but once it cooled, stars and planets appeared.

//Ms. Mc: Good answers and pictures. Needed to refer to figure 1 in your text as well. 9/10//

The scientific term robot was first introduced in the 1940's in a short story written by Isaac Asimov where he included the Three Laws of Robotics. A robot is an artificial person who acts and has the same duties a person would.**

The Ultimate was installed in the 1960's to lift hot sheets of metal. Most robots these days are built to perform jobs that humans are physically not possible, such as lifting hot sheets of metal or giving someone surgery. Robots are also more reliable, precise and accurate. **
