Albert and I did a well drawn sketch of our rube Goldberg. The sketch is easy to follow and labeled with letters. The sketch is accurately represented. We had six simple machines that were labeled correctly and had a well-written explanation for each. There was some human assistance beyond the initial start. Our machine has eleven steps that were labeled correctly. There were six simple machines. The apparatus was completed.

Rube Goldberg and Simple Machines

Rube Goldberg 

Rueben Goldberg was born on July 4th 1883 in San Francisco . In 1900 he graduated from Lawrence High School. In 1907 he moved to New York and worked for several newspapers. He married Irma Seeman in 1916 and had two children, Thomas and George. On his “Rube Goldberg Machine” work, he would spend over 30 hours on each piece with close attention to precision regarding the lines and details.

His cartoon strips were popular but the work that gave him unforgettable lifelong fame was the character he created, Professor Lucifer Gorgonzola Butts. 

1. What are the relationships between forces and motion? F*M=AF=M*A 
Newtons first law: An object at rest will stay at rest unless another object is acted upon it.

2. What are the variables that affect motion and force? It is affected by the initial speed and acceleration and the most important is gravity, air friction, surface friction. All of these forces are proportional to the mass of an object.

3. How does Newton’s three laws describe the motion of a moving object? 

4. How does gravity impact objects?
The formula for gravity is G= 9.8 m/s. 
Gravitational pull is G*m1*m2/r^2 
If the object is big then the gravitational pull will be stronger than if there were too small objects.

       I learned a lot about Three Newton Laws. Before i did not know anything about the laws. Now I know all sorts of things like the 1st law of how an object in motion stays in motion unless acted upon another force. I also learned about the second Law of motion. F=MA which is Force= Mass*Acceleration. Finally i learned about Newtons 3rd law  which is for every action, there is an equal and opposite reaction.
Action-retraction forces

Museum of Science

When our physical science class visited the museum of science we saw a lot of things. The first thing that we when to go see was the Fantastic Forces show. There we learned how newtons cradle works. We also learned about momentum and the lady that presented the show demonstrated the show showed us with a bowling ball. When she was trying to be funny she was awkward. When we went to the lightning show i did not like it that much. I learned where to hide when there was lightning.

Gives energy for cells by breaking down sugar molecules which change into energy
