We wanted to see if we could pop a balloon. My group has not
calculated the mechanical advantage. The energy that we used is that we do not
know what it is because we didn't get to that point. We did not have any
difficulty until we got to a point of where we didn't know what to do next. We
did use four out of the six simple machines. We used incline plane, wedge,
wheel and axle and lever. I drew out all of the draft of out project
but I didn't do the final drawing of the project. One of my partners and I did
pretty much all of the hard part. We had 11 steps to be able to pop a balloon. A.
Car goes down a ramp and one of us hits it B. Car hits the golf ball C. Golf
ball goes down the first ramp D. Golf ball goes down the second ramp E. The
metal bar falls on the fork. F. The fork flings the wooden block up G. The cube
knocks the domino's over H. The domino's hot the ball over so it falls off the
table. I. The ball lands on the sew saw J. The see saw pushes the pin over K.
The pin pops the balloon.

“Rube Goldberg and Simple Machines”.
1. Rube
Goldberg is
employed by the New York Journal America until his retirement in 1964 where thereafter he made bronze
sculptors. He makes sculptures of things.
He makes scripts of what he did. He created many things The
Weekly Meeting of the Tuesday Women's Club, Lunatics I Have Met, The Candy Kid, Mike and
Ike, Boob McNutt, Lala Palooza, Foolish Questions, Sideshow,
Father Was Right, I'm the Guy, and They all Looked Good When They Are Far Away.
2. “Journal Entry: Energy Transfer and
Simple Machine Learning”.
3.
| Inclined Plane-A plane is a flat surface | |
| Wedge- a wedge is actually a kind of inclined plane | |
| Screw- take an inclined plane and wrap it around a cylinder. | |
| Lever-an arm that "pivots" (or turns) against a "fulcrum" (or point). | |
| Wheel and Axle- moves objects across distances. | |
| Pulley- a cord wraps around a wheel. |
4. For
each simple machine, provide instruction for calculation of mechanical
advantage.
Lever: MA = length of effort arm ÷ length of resistance arm.Wheel and axle: A wheel Has a lever on one arm and rotate it.
Pulley: Pulleys change the direction of a tension force on a flexible material.
5. For
each simple machine, upload a picture depicting the simple machine.

6. Write a
brief description of types of energy and how energy changes.
Nonrenewable Sources of Energy is it is gone
forever.
Renewable Sources of Energy is it can be used over
and over again.

Newtons quiz
1. What are the relationships between forces and motion?
The relationships between forces and motion is the potential energy that will be given. Force is the amount of pressure that is being given. The motion is the the movement being applied. An example is the the car.
2. What are the variables that affect motion and force?
The gravity is affecting the motion and the force. The speed is depending on weather if the gravity is being affected.
3. How does Newton’s three laws describe the motion of a moving object?
The first law is whatever is in motion stays in motion. The second law is it will only move if theres a net force or an unbalanced force. Newtons 3rd law is for every action so there will be an equal or opposite reaction. You have to put all 3 parts of the Newton's laws to explain this.
4. How does gravity impact objects?
This can push something toward things. They might be going out but instead they will be going in. This happens to things if theres a different mass or acceleration.

Proving Newton's Second Law
Proving Newton’s Second Law
Question- What is the relationship between force, mass, and acceleration?
Materials used
·
… Car, weight,
books, protracker, 2 spring scales, and a table
Hypothesis- I think that they will way pretty much the same.
Procedure-
11. Collect Materials
22. Set Up
33. Make sure I had my journal and pencil
44. Make a graph in my journal
55. Start our lab
66. Pull weights up the ramp 9 times with the spring scale
77. Calculate the acceleration
88. Clean up materials
99. Graph the data which means on 1 graph mass
(x) and acceleration (y) and then on the 2nd graph angle (x) and Acceleration
(y) and it’s a line graph
110. Answer the questions in my journal
111. Put away my journal and pencil
Results
Data Table
Graphs of Data
Conclusion and Analysis- They were the did the same thing
with the graphs because ours went in a straight line.
1. What happened when you kept the mass the same and changed the angle?
It stayed the same and it didn't change.
2. What happened when you kept the angle the same and changed the mass?
It did the same thing as the whole time.
3. What was the relationship did u notice?

Museam of Science Feild Trip
Fantastic Forces:
During this part we had a show. We saw the pencil try to go through a piece of wood. Then we saw the pencil be put in the machine and then it went through the wood. Then we saw the forces of the bowling ball also called Newman cradle. Then we saw that the cup didn't work pushing it across the floor. Then we did the cup with plates on top of it and she pulled a napkin from underneath. Then she did the same thing with the water in the cups. Lastly I like show everything for most of the time worked and was cool.
Engineering Design, Bobsled Activity:
My bobsled worked the whole time but I did fix it to after I went. I used fabric and 2 small clips. Then I put in four batteries in it on the front of it. Mine worked and I was surprised it did. Mine did not have any problems at all.
The Lightning Show:
I liked the show even though I have seen it before. I liked everything that he did. There was not anything I didn't like at all. I learned that there is 120 little thing that the 2 balloons popped over. I would recommend it to do that again.
Audiokinetic Sculpture:

Audiokinetic Sculpture:
The ball I followed went left to right. It made a trigger sound when it went down. All of them were simple machines and it went down 3 times. Then it encountered all of the balls. They started at the top and went all different ways.

Energy
I think it was different because it was something I have never done. I think that I learned that the kinetic is different from the potential. This is something I would do again. I think that it was was different from just taking notes. I would recommended it to do it again.

Chemistry
Proteins contain Carbon, Hydrogen, Oxygen, and Nitrogen. It also had 20 or more amino acids joining. Then it provides a structure and transport cells in or out. Lastly it helps fight off diseases.
Lipids store more energy and wont dissolve in water. Then it steroids act like a messenger. Lastly they are made from gysoral heads and have a double or tripe bond.
Carbohydrates are made from Carbon, Hydrogen, and Oxygen. Then it is a main energy source and break down sugars. Then a large molecules of many monosachrides are called pollysachrides.
Nucleic Acids contain Carbon, Hydrogen, Oxygen, Nitrogen, and plus Phosphorus. Then it is formed by bonding of individual units called Polynucleotides.
