Thought Questions:
 

1. Describe your thought process as you developed an initial idea for your egg-catcher.

My thought process was to find out the best way to absorb the energy that was running through the egg and soak it all up as well as I could with all the materials I had. We also needed to improve the whole that the egg was being dropped into. We took these ideas and put it into one structure. We cut holes near the bottom of the cup and strung straws through them. Then on top on the straw we put a piece and a half of paper that was shredded up and fluffed it up on top of the straws. Then with our four popsicle sticks we taped them o the bottom of the cup so it could be more stable. With the half piece of paper left we warped it around the top on the cup so that we could aim the egg in easier.

2. Describe what changes you made to your design as the competition went along. Tell why you made those changes. Include a detailed and labeled sketch of your best design.

Some changes we made to our structure where that when we started out we didn't have the cone on top and the straws near the bottom, and one big thing was that on the bottom of our cup where we put the popsicle sticks we stacked them on top of each other making it unstable because each stick is on a different level instead of being flat on the bottom. Things we changed were on the bottom we had rubber bands stretching for side to side on the cup. We decided to put straws in for the rubber bands because the rubber band would make the egg bounce back up in like the straws did. When aiming came in, we did not have the best aim, we figured out that we didn't need as much fluffed up paper so we only used a sheet and a half of paper and the rest we put on top to improve our aiming.

3. Give a second-by-second descriptive account of your most successful trial.

Our most successful trail was when we had the string lined up right on target on the cup and Scott's hand was not shaking at all but still. I was at the bottom, where the cup was waiting for the egg to be catch. I just got done fluffing up the shredded paper and walked away slowly not breaking Scott's focus. We both looked at each other, i started the countdown 3, 2, 1, he dropped the egg right into the middle of the cup. It was so silent not a crack could be herd.

4. Describe the difficulties you had with this project. (e.g. Did you give your best effort?  Did you have trouble with design?  With equipment?  With construction? With execution?)

During this project Scott and I gave our very best effort from day one to the last day. We focused on what would be the best way for the egg to land perfect in the cup, with out cracking. Our biggest trouble with this project had to be getting the straws through the cup perfectly. We had the use a lot of different cups so we could get it perfect. Every time the straws would make bigger and bigger holes leading to the bottom of the cup. Making the straws no good. After a long time discussing how to fix this problem we came to an agreement by putting a piece of tape under the straw so it could not move down when the egg is caught.

5. Tell what you could have done to improve your egg drop project performance?

Scott and I could have improved our aiming techniques a lot better. Our aiming wasn't too bad but after looking back we could have made it a lot better. In fact after the day that we finished Scott made this outstanding way to improve our aiming. He brought aiming to a whole new level with this device. With it we could have maybe set the record for highest egg dropped

6. Describe the motion of your egg mathematically* and by creating at least one graph. [*Note: include average speed, acceleration, momentum, and force of impact calculations. Show three steps.]

When the egg is being dropped it goes through three different steps. Acceleration, momentum and force of impact. When the egg is dropped it moves through different steps. 1. Starts to accelerate to different speeds. 2. The movement of speed increases the momentum until it reaches it final speed. 3. Once the egg is dropped the is a force of impact that hits the the egg catcher and the egg hopefully lives to see another day. Everything will be different from different heights  The egg moves through these stepped every time it is dropped.

Calculations

Speed= 3.5m/0.67sec            5.22m/s

Accel.= 8m/s/0.67sec           11.94m/s/s                                                

Momentum= 0.0654*5.22     0.34kg*m/s

Force= 0.0654*11.94             0.781N  

7. Discuss how momentum played a major role in this project.

Momentum played a role in this project because each time you move up, the momentum gets increased by a certain amount of time. Each drop you have to make up for the speed by improving you egg catcher by a littler so it won't get smashed at and you have to make a whole new egg catcher.

8. Describe the forces acting upon your egg from the time it was in your hand to the time its drop was complete.

When the egg was being held in Scott's hand the egg was getting pulled down by force. Then once he let go of the egg the force came in and took it down at a rapid time all the way to the surface. As we moved up each meter and a half the force began to become stronger when it was dropped. It had more time to pull it down with greater force. Then when the egg is hopefully caught the force is stopped because the egg can't go down any farther.
9. Make TWO connections between the egg drop project and concepts from Chapter 2 of the science textbook.  Be creative and think with depth.
Friction
When the egg is dropped into the catcher it starts to gain more and more speed. After falling, it finally reaches the egg catcher. With all of my modifications to the cup, there is enough friction so that when the egg enters the cup that it will slow the egg down and catch the egg safely.
Weight
Each egg has a good amount of weight. When the egg is dropped from a certain amount of meters the eggs weight then shifts and starts to head toward the cup at a rapid past. The egg shifts is weight in mid air because the yoke get's pulled down, when inside of the eggs shell.

Guided Learning 1st Trimester Skills for Success Review/Reflection

1. Look back over your blog entries from this year and make sure you have tagged/labeled them with one or more of the following 5 Skills for Success.

• Work Hard & Persevere
• Learn
• Collaborate
• Communicate
• Solve Problems

2. Write a new blog reflection that answers the following questions with complete thoughts that are explained and supported by evidence.

1. Which of the five Skills for Success is your biggest strength? Why? The skill I think is the biggest strength for me is collaborate because I am very good at saying what is on my mind to the teacher or in a group project.
2. In which of the five Skills did you show the greatest improvement during 1st trimester?  I showed the most improvement in learn because before I would always get distracted and not pay attention and then I would not know what we we had to do. So I really worked on learning everything so I wouldn't have to ask stupid questions.
3. Which of the five Skills do you need/want to improve the most? Why? I need to work on Solve Problems a lot more because sometimes I don't finish everything through. I need to go and get more help when I have an opportunity.
4. What specific actions will you take in order to improve? Going to seek help from my peers instead of trying to finish everything really fast and not doing the best I could on the whatever the assignment is.
5. What resources/assistance will you take advantage of in order to improve? I will use my Guided learning the most I can to get help on work or ask questions on assignments. Also I can get help during Study Support.

AWESOMENESS

Motion test reflection

Discuss how successful you were on each of the four sections of the test. Give evidence.
     I was very successful on the test. Each section I did very good. I used the techniques to remember each thing on the test. The Multiple choice I only missed one question. On the Calculations I didn't do to bad, I knew most of the questions but made some silly mistakes. The writing section I tried my best on each question, I could have gone into depth on each question a little more. Overall each section I got at least 3/4 of the questions right.

Explain how you could be more successful on the next science test.
     I could be more successful on the test by reading over everything more than I did on that last test. On the next test I will look over it more and after I am finished and really make sure that i'm not making and careless mistakes. Some techniques I could use on the next test could be finding little ways to remember stuff.

Compare this test and the marshmallow challenge. What do these two activities tell about you as a learner.
     In the marshmallow challenge I would approach questions quickly and over come them as fast as I could so that I could work through them. In the test its a lot different I have to study everything more and really take my time to figure how to do it and what everything is. I can't just go out and throw ideas out and hope they work.

Middle East Reflection

What makes the Middle East an important region historically and currently?

     The Middle East is historically important because there where all these wars in the Middle East a long time ago. The U.S has noticed all these wars and it makes them very tense because it hard for us to start to trust them. Now the Middle East is very important because that is where we get most of our oil from there. We also have a lot of troops their so we always have to be careful of what we do, because if we start to attack and wipe out places they could raise the price of oil and it would make every one have to pay more.

How has its physical geography shaped its cultures and history?

      Every year at the Fertile Crescent the snow melts from the mountains and the Tigris and Euphrates rivers flood. It takes all of the soil and brings it down to the valleys where it's spread out.This makes everyone want to move there and grow their crops in the rich soil. The mountains are a good barrier so the people couldn't get attacked as easily. Only some cultures survived the harsh area. The Taurus Mountains separated empires too. Mountains have always divided people and helped people to escape to the mountains. One example is the Christians who escaped when they were getting prosecuted. The waterways have shaped the culture because they had to ship goods at places like Mediterranean Sea and Red Sea. 

How can I effectively research reliable facts about geography, history, and current events? 

     There are many different ways to find out good reliable facts about geography, history, and current events. The ways I like to use to find facts are by going to video clips about whatever I am studying and find out information about. I think its a lot more easier to understand then to just read word after word about your topic, but it's just a personal preference. One other way is reading and making sure that is a good website and not just some fake stuff about your topic. Finding reliable facts is just a little bit more challenging then finding videos because all though that there are fake videos its easier to tell the difference then by reading it off a website.

SCRAVID reflection

SCRAVID was a great to help with reading. i used the methods some but not as much as i would like to in the future. I used them while reading Enders Game by Orson Card. The stradegies are: summerize, make connections, re-read, ask questions, visualize, infer, and decide. I have to re-read a lot because i have a hard time understanding the book sometimes so it causes me to re-read. I also like to make connections to real life. Making connections helps me better understand also because it might make me think about whats happening in every day life compared to whats happening in the book. I think the SCRAVID stradgey will help me read books in high school and in college a lot better. In Enders Game i re-read a lot because a lot of different people talk in the book so i had to understand who was talking. I make connections usually to events that happen in my life and that i live. I hope to get better at these stradegies and maybe it will help me become a better reader.

Interim Science Reflection

Well all of the x's I put down where closer to the developing but when I really started to compare Mr. Lammer's and my x's together I noticed that his where all more toward Proficiency then my where. The only one that was pretty much in the same spot was "Communicates thoughts and ideas by was of writing and oral presentation." The biggest difference that were different was "Solves 8th grade design/engineering challenges," when we first started out I thought that everything had to be perfect, but once when I got done with the Jet Car challenge I got a lot better at just going with the flow and failing at first then fixing whatever needed to be needed. I have improved a great amount on "Collaborates with peers and science teacher," because I always put my thoughts out even if nobody uses them. Also I listen to what another peers say, and   always try to include their ideas in anyway.

Painting

Starting from the beginning of the year, i have really started to take an intrest in Painting and drawing. Mr. Congo has shown us some really cool art pieces that i think are awesome. I am starting a new painting of one of my favorite skiers named Ian Compton. He is in a really cool position skiing so i picked it out and that the painting im going to do. I really hope that it turns out great!

Root word reflection

Well in the Test i did not do as well as i thought i was going to do. I studied long for two nights.

Some reasons i think i did bad:

• Didn't quiz me self enough
• Got distracted during studying
• Got nervous and didn't have enough confidence 

What to do, to do better on the following tests:

• Get a peer to help quiz me on the test
• Study for a bit longer
• Not get nervous
• Really think every question through 

Jet car

Jet Car

    In the past weeks we have been learning the techniques and putting them to test for a jet car. For example, one of techniques was to plan out many different designs then find out which one succeeded and failed. This is a not a ordinary jet car though its a car made out of two straws, four mints, one kabob stick, one index card, and as much tape as you want. Then you have to design a “jet” car out of these supplies. The class really had to find out how the motion of the car really worked, which was a big challenge.

    After all the test my farthest distance was 8.36 meters which is an A+, I think that the grades were very fair, because you have to master the model of your car. It took lots of hard work to find that one model that worked the best. All in all i think it was very smart to have your grade be the distance that your car travels.

    The perfect Balloon jet car would be measured out completely so its very symmetrical. The wheel would have to be very smooth and can be easily rotated. Also you balloon has to be pointing in the exact spot so it can move with a high amount of speed. The last and most important is that the axles have to be very tight and they can’t move and turn your car. Thats the hardest part usually the axles are wiggly so it turns the car.

    Your car always is reaching different speeds from point A to point B. The speed is the heart of your care. You have to have a good heart to get that speed that you want. Everyone once in while you would have to get a new balloon because they get weak after pushing all the air out previous times. The distance was what determined if your car was put together correctly, it will show in the grade that you get.

    On my run that a got a A+ on. it had a amazing run. It curved out to the desks and then curved back right into the last little hallway changing speeds all throughout the run. I thought it was going to be horrible because it started off really slow then speed up to a very fast speed, and then the last boost moved the car to the right spot to reach my goal. It shows that all the speeds can really change your mind quickly as you watch your car, first the think its horrible then all the sudden you get relieved with an amazing boost of air to push the car to its destination.

    One problem i had while making and testing my car was that the wheels were too loose and would wiggle and run the car into the wall. Another one is that whenever i got a balloon i would use it way too many times and get really old and not strong. They way i fixed the wheels being loose what getting a good amount of tape and putting them on either sides of the wheels so they can still roll but not turn alot. I fixed the other was by not filling the balloon all the way up because it would spin the car out and also make the balloon worst, it surprisingly helped out alot because every run was solid and a good pace to get the to the 8 meter spot.

    A real-life problem that a car maker would face would be making everything too complicated because you get too caught up on these little problems when you are missing this obvious  problems. This happened to me alot because i would make a “cool” design but it would be a total fail. A way to help make that not happen is make a simple one then work on making it look fancy from there.

    

    I learned that with hard work and perseverance that you can earn the grade that you want. During the beginning i got a A- and stopped for awhile then once i saw that everyone was getting past the 8 meter spot i stepped it up and started the really try hard to beat peoples records.
   
    On the following projects i am going to start planning ahead and making alot more prototypes and really experiment with everyone. I had a trouble sticking with one creation and really testing them, it seemed like i just wanted to get a good grade and be over with it. I’m going to make my self really think about everything i make and make sure that i was really thought it out.

Fall Overnight Reflection

During the overnight was a fun way to grow with our class. We got to have fun games that wear also away to learn during these games. Everyday we had different goals to concur every day. My favorite part of the overnight was when we got to be a 3rd world country and get to cook to for our country using the supplies we got. I thought that it was a really good experience to  bond with your team and be able to see what people strengths are. We also got to experience how hard it is to survive when you are a 3rd world country. Over all i thought this was a very good overnight the best so far and i look forward to have other good ones like this one

Jet Car Reflection

In this project we had a certain amount of supplies and test me could do. We would have to make our own cars a try to get a certain time, distance, or do a jump form table to table. I made a car and i am able to say i succeeded in this project. It took me many tries to get the perfect run. I got 8.36 meters. It took a lot of fails to get the perfect run. Then trick that made my car very good was balancing it out, because if it is slanted a little bit one way it will turn one way and not be straight. You fail some and you win some, but i just got lucky and won this one.

I have put a jet car into motion. My farthest is 7.47. MY grade is an A.


2) What is your opinion on the Balloon Jet Car project so far? Which challenge are you planning to complete?
This project was a really fun brain twister. You think that the most complicated version of a jet car will work, but in the end the simple car worked the best for me. The hardest part about is was that figuring out why it was turning a certain way.


3) Which of these statements best describe you?

1. “I have mastered the balloon jet car challenge!”
2. “I haven’t mastered this challenge yet but I am close.”
3. “I wonder if I will be able to master this challenge.”
4. “I am very frustrated and I am sure that I will not master this challenge.”

• my wheels roll freely with little friction
• my wheels don’t wobble-this one
• my car is not too heavy or too light
• my car is carefully built-this one
• my car does not turn easily
• my effort has been outstanding…I have worked outside of class on the project- mostly this one
• my effort has been consistent…I do not socialize when I should be working-most of the time
• my effort is ongoing…I plan to persevere to success

5) If a jet car travels 6 meters in 9 seconds, what is the car’s speed?
1 meter in 1.5 seconds




6) Is the answer in #5 an average or instantaneous speed? Explain.
It’s an average because it starts at 0 the reaches different speeds throughout its time from point A to point B.



7) What extra information is needed in question #5 to turn the speed answer into a velocity?
Away from Mr.Lammers desk (Aka South) and towards the door.
