The purpose of this experiment was to see how mass would affect the flight and how trigonometry could be used to measure the height of the apogee. To allow the rocket to fly, the solid rocket engine is burned, and gasses are expelled very quickly out the bottom. According to Newton’s third law, every action has an equal and opposite reaction, so the rocket soared upward very quickly. It was hypothesized that the less mass a rocket has, the higher its apogee would be. This was because the less mass something has, the less inertia affects it. With less fuel used to overcome the inertia of the rocket, more fuel can be used for acceleration, causing the rocket to fly higher. The rockets mass and apogee have no relationship with the data. The hypothesis was incorrect because the mass of the rocket seemed to have nothing to do with the apogee height. A rocket with the mass of 44 went higher than a rocket with a mass of 41.5. The relationship between the points is no relationship. A rocket with a mass of 42.1 went 98.3 meters while a rocket with the mass of 41.5 went only 96.6 meters.

Include at least 2 pictures that you have uploaded to supplement your written work. Don't forget to give them a figure # and title and refer to them in your paragraphs (i.e., "As seen in Fig. 1 . . .). Your final log entry should contain:

1) The date of your entry. 2) A two paragraph summary of robot history (can be longer). 3) Two reasonable sized pictures (see entry 2 below for more information). 4) Correct spelling & grammar.

May 2, 2010 The idea of robots goes back as far as the time of Greeks and Romans. The god Hephaestus was said to have built golden robot maids. Humans have always wanted automated machines to make life easier for us. Robots are the answer. The word Robot comes from the Czech word robota meaning servitude. Many of the first robots were just used for entertainment purposes. Later, weaving machines were created, and could be contorled by punch cards. Robots weren't used in industry until 1959, when they were demonstrated at M.I.T. Two years later, the first automated robot was used in General Motors car factory. The Rancho Arm was created to help handicapped people because it has six joints, and works like an arm.

Robots have gone a long way from back then. They are much more sophisticated and are now used to help with space exploration. They have been used to help in all sorts of ways. There are even humanoid robots now. They look and act like humans. Robots help people everyday, like helping them walk, to helping them do simple tasks if they are handicapped. Robots are helping us everywhere.

__Written Explanation of Code__ (Write first in Word, then cut and paste onto your page.) a. In a short paragraph, explain what EACH block in the code specifically tells the robot to do. For example, the second block is a movement block that tells the robot to move forward for 1 rotation at 75% power and then brake.”

Date: May 7, 2010 Challenge: Cha CHa slide

The point of the challenge was to make the robot do the steps of the dance Cha Cha Slide. The robot did the dance in time with our verbal commands.

media type="custom" key="6079375" Video 2: robot Cha


 * Figure 1: Cha Cha Code**

The first block is a movement block. It has the power set to 75%. It is also set to turn left. The second movement block has its power also set to 75%, but it goes straight. The third block is set at 75% and to move backwards. The fourth block is the same as the second block: 75% and straight. The fith block is set to 75% power, but moves right.


 * Figure 2: Cha Cha Code 2**

The first block is a movement block set to 75% power. It tells the robot to move left. The second block tells the robot to move left also. It has the power set at 75%. The third block tells the robot to move forward at 75% power. The fourth block is set to move right, at 75% power. The fith block tells the robot to move forward again, at 75% power.


 * Figure 3: Cha Cha Code 3**

The first block tells the robot to move backwards at 75% power. The second block tells the robot to move forward now. Also at 75% power. The third block tells the robot to move backwards again at 75% power. The fourth block tells the robot, at 75% power, to spin right 1000 degrees. The fith block, also at 75%, tells the robot to spin left this time for 1000 degrees.




 * Figure 4: Cha Cha Code 4**

The first block is a movement block the tells the robot to go backwards at 75% power. The second block is a display block, which tells the robot to display a smiley face. The thrid and final block is a wait blcok, that tells the robot to wait and keep the smiley face displayed on the screen for three seconds.

__Life__ Review your notes about the characteristics of life. In a proper paragraph describe the characteristics a living thing must possess. Include one picture that pertains to the characteristics of life. Next, spend some time researching how we can detect life on other planets. Write a proper paragraph on the scientific methods you could use to discover life on another plant. Include one picture that pertains to finding life on another planet.
 * SLMM - Log Entry 8 **

Your final Wiki entry should contain: · A title describing the contents of the entry · 1 paragraph summary of the characteristics of life · 1 reasonable-sized picture related to the characteristics of life · 1 paragraph summary of how life can be detected on other planets · 1 reasonable-sized picture related to detecting life on other planets · Correct spelling & grammar

To be truly alive, you must be made of cells, need materials, homeostatic, respond to stimuli, reproduce, grow, adapted, and respiration. Cells are the fundamental building blocks of all living things. There are two types of cells: animal cells and plant cells. It must need materials like water, minerals and air. They also must be homeostatic. They must be able to stay about the same internally while the enviroment around them changes. Another thing they must do is respond to stimuli. They do not necessarily have to move from one place to another as plants cannot move, but plants still move/grow towards the sunlight. Thus responding to stimuli. To be alive, you must reproduce. You must be able to sexually reproduce, as mammals do, or a-sexually reproduce, as bacteria and some plants do. You must grow through your life from a simpler form to a more complex form. Also, to be alive, you must be adapted, to help your own survival. The point of adaption is to make living easier. Finally, you must respirate. Reperation is releasing the energy in the chemical bonds of sugar through combustion.
