Rube Goldberg #5 Our Finished Product

We FINALLY finished our Rube Goldberg! I’m so happy. We worked so hard on it and even after watching other people having to change their tasks we didn’t have to and that also made me happy. We have a finished Imovie that I will show you right there. I hope you like it. I’m just so proud of ourselves and my whole class because this wasn’t an easy project but sometimes you do need an extra challenge and this was definitely a fun challenge. If you made this, then after all this work, trust me, you would be proud too.

I hope you have enjoyed this and maybe even try this task.

Rube Goldberg #4 Challenges/Struggles

As we were building our Rube Goldberg we faced many challenges. Sometimes one of our steps wouldn’t work, or we couldn’t get something to stay put. This post will walk you through our challenges of building our Rube Goldberg.

Our first challenge was trying to actually focus. Now you might be thinking “What kind of a challenge is this?” But let me tell you, while with your friends your brain basically tells you “Have fun! Your with your friends no one cares about work.” And you have to make sure you tune that part of your brain out. The first few times, this was challenging for me and my partner, but as the days went on and the due date was coming closer, and closer, we got more focused. Eventually we did finish and we think it went great.

Our second challenge was changing stuff around mid-build. We had to do this because, sometimes before you even try it you have a feeling something isn’t going to work and, the more you think about it, the more it seems like it won’t work. For example, our springboard. At first when we thought about it in our heads we thought it was going to be unique and awesome. But, we weren’t thinking of the actual mechanism. Once we built it, we ended up with a spring glued to a piece of cardboard and, we both knew it wasn’t going to work. This is just one example but there are so many more that it would take a VERY LONG blog post just to name a few.

Our third challenge was finding the right places to put things. This might sound weird but there is a definite struggle with this. Heres and example: We had a pulley. This pulley held very heavy things. Our original plan was to hang it up on the ceiling, but that DID NOT end well. We almost tore a hole in my ceiling. So ten we had to switch the place of the pulley and while we only switched the place of one thing, that one thing was very important. So as we switched that, we had to switch everything else around

These are only a few of our challenges but there are many more…

Immigration Filming

Today in class, we were filming for our immigration project. Our teacher said that it was more of a testing day and that it was ok if we didn’t get any filming done. So, my group was trying to find a good angle with the camera. We tried it up close, which didn’t work because then you could see even, the slightest smear on the characters. Then we tried far away. The problem with that is, that when we have the camera far away we have a broader view. So with that broader view, we could see the background behind it, (as in the lockers). So we decided we could put paper on the sides. We didn’t want green paper because, with a green screen the picture we have as a background would also spread to the sides. Eventually, we decided to put back paper o the sides. The reason being, that we didn’t want a color that would pop out and black, being so dark, is a perfect color because it wouldn’t pop out at all because, most of our pictures and backgrounds are black and white.

Once we figured that out I had to find out how to use the green screen. I figured out how just fine. But, it wouldn’t work. I tried making a folder of images on the desktop and once I tried to insert it into the app, it wouldn’t show up. So, as you do (hopefully) I asked for help. A kid in my class helped me and taught me how to insert the picture for the background and now, we are pretty much all set for filming. I do hope that we will be able to finish on time!

Rube Goldberg #2 Steps & Energy

As you already know if you have read my previous post, we are doing a Rube Goldberg Machine project in class. We have to write down a materials list and a written plan down on paper. We also had to see what energy transfers throughout our project. Here is a list showing my groups steps and the energy between the steps.

  1. Rc car going down a ramp = potential energy ➡kinetic energy
  2. Hitting car thus pulling off the weights = energy transfer = kinetic energy from rc car to plastic car to string. This leads to the weight being pulled off
  3. Since the ball was sitting on a spring board that had potential energy. Then it was kinetic energy when the weights were pulled off.
  4. The ball hits the cup that is balanced on a piece of wood. The cup has potential energy that is then transformed into kinetic energy when the balls knocks the wood out from under and the cup falls.
  5. The pulley which also has kinetic energy is put into action then the books drop on the lever which is now uneven opens the laptop because the higher side is on the side of the laptop.

This may not be very clear and may not be how this project will be when it is done but, I intend to make 2 more posts. One further explaining the process of this Rube Goldberg project ( as in showing pictures of our plans and clearing up what they are, what different designs we have, what we might reconsider, etc.). Another showing a video of our finished product and explaining the changes we had to make.

Rube Goldberg

In class, we have started a project called Rube Goldberg. Now as some of you may not know Rube Goldberg was a person. His real name was, Reuben Garrett Lucius Goldberg. He was a cartoonist, author, sculptor, engineer and inventor. We now have machines that we call Rube Goldberg machines. That is what we are building in class. We have detailed sketches and research. We have to go through the whole design process. Testing and re iterating. We still have to finish building. Next post I will try to show pictures.

My Comparing Essay

In class we are writing essays. As you may know already there are different types of essays. There are persuasive essays, narrative essays, descriptive essays, expository essays, and comparing essays. As you already know from the title, this is a comparing essay. I am using two Patricia Polacco books. My Rotten Redheaded Older Brother and Chicken Sunday. I hope you think highly of my essay.

In books, people change. It is an essential part of literature. Novels, short stories and even picture books all have this trait. The books, My Rotten Redheaded Older Brother and Chicken Sunday, by Patricia Polacco, are both great examples of this. The characters in this book aren’t always what they seem. The children, in both these books are perceived in a way that makes them seem “rotten” or “foul”.

In the book, My Rotten Redheaded Older Brother, Richard (The rotten redheaded older brother) starts out as a very mean and competitive older brother. He always tried to become better than his sister at any competition. He would also always make things competitive. Richard taunted Tricia. He would say” And I’m 4 year older than you! Always have been, always will be!” But then, at the end, Richard finally made peace with his sister, because Tricia “Did something special”. This shows that Richard wasn’t what he seemed to be.

In the book, Chicken Sunday, multiple characters are misperceived. One of whom, was Mr. Kodinsky. He was misperceived in a way that made him seem grumpy and crabby. Yet, once he found out about the truth he forgave the kids almost instantly. Another few characters that are misperceived are the kids. But, the kids are only seen in a different way by Mr. Kodinsky. This is because, to Mr.Kodinsky, it looks as if the younger children threw the eggs at his door, not the older ones. But at the end, both, the kids and Mr.Kodinsky seem to show their true colors.

The theme that runs through both of these stories, transcends into life also. In life, people aren’t always what they seem. Sometimes, someone can seem mean and grumpy, yet with a little pushing from the right person, they can become one of the nicest people you have met. Or, vice versa. These two books are great examples of this and show exactly how this idea can be brought into general life.

 

My Writing Expedition Thus Far

My writing has been a great expedition. I came in to 5th grade thinking it would be the same type of writing. But now, when I look back to what we’ve written I’ve realised we have tried so many new things.

This year was the first year I have made an Infographic and an article. I have written non-fiction but an article is different. It is like telling a story but with facts and dates and basically reporting what we know so far. There are also things I was already familiar with and I really disliked them. The writing that I am most proud of is my constitution project. The reason, I did something I like and conveyed the information I wanted to convey in a fun way. I also enjoyed it a lot because I also got to build. I included my building into my writing by going back to it. I didn’t like the essay’s because they aren’t something where I can just search for my information on the web. Instead, I have to think of a statement that sounds somewhat philosophical, which I don’t particularly enjoy.  

I look back and realize I have grown a lot as a Writer.

Constitution project

In class we are doing a constitution project. We have two cubes that we roll to find out what topic we have and how we will present it. My topic is technology of the constitutional era. We had to go more into detail about the invention we were going to talk about so I  picked a suspension bridge. I will present my information by using an app called “Explain Everything” Where we label and caption pictures and videos. And since I really like to build my teacher let Me build a model of a suspension Bridge. I am making it mostly out of wood and I am using some cement, metal wire, and screws. I am going to start building today. I just hope I will finish in time.

Redesigning our Rocket

This is our revised rocket

After the first launch my group had to redesign our rocket. Our first step was to analyze the problem. Our problem was that our wings were unbalanced. This was because we only had 2 wings. We also thought it was a little top heavy so we had a lot of debates of if we should keep the extension we had before or take off. We decided we would cut it shorter and put it on the rocket. But we also didn’t know if we should 3D print our nose cone or keep the one we had before. At the end we decided we would add more wings, take away the extension, and 3D print our nosecone. Redesigning was actually very fun and I cannot wait to launch our revised rocket.

 

 

Rocketry Launch No.1

In school we have been doing rocketry. Yesterday we had our first launch and everyone was excited. We have recorded data and made graphs to see which groups rocket went the highest, and which groups went the lowest.

Based on the data, Blasting Rockets (My Group) launched lowest yesterday in the field with ≈ 20 m, and J.E.X.L launched the highest with 57.5 m.

Our rocket didn’t go that high compared to other rockets. Why didn’t our rocket go high? The reason is that, the rocket had a 2nd bottle extension.* The extension was to attach the nose cone. We thought it wouldn’t add that much weight because it was hollow. Our hypothesis was incorrect. The extension made the rocket top heavy which made it go in a U shape*. We also only had 2 wings, which made it unbalanced. The mix of those was bad. The reason it was bad is, when we only had 2 wings it leaned a little towards the right. The extension made it fall even more towards the right and eventually it turned completely over and fell at a very low height.

In the second launch, I think we should take away the extension and add more wings. Adding wings will add stability, and taking away the extension will take away that extra weight.

I learned there are different ways to launch water rockets. At first I only knew about the liquid nitrogen and the cork and base. I learned there is also a launch pad with a bike pump. The launch pad is the one we used.

I only have one question now; Will our rocket go the highest after the revisions?
