I think that this project not only tested our skills at designing, but it also tested our patience. To get to this finished product it took a long time and we had to keep on testing and modifying. It also tested how well we knew the design process because if you skipped just one step it could throw the whole process off. I think this was a good learning experience and I think that this project was very fun. Maybe if we had even more time then we could make these projects superb.
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.
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…
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!
As I said in my last post, I intended to make 2 more blog posts. This post is to clear up our steps, share our changes in the plans, and explain in pictures what we are talking about. First I will clear up our plan (Look at the pictures below to help).
1-2 : Our first step was to have a robot push a car in the opposite direction of a springboard. On this springboard there are weights keeping the spring down, full of potential energy. These weights are attached by a thick string, to the car. When the car moves in the opposite direction of this springboard, it pulls the weights off with it.
3: The springboard that is now released has a ball on it. When the potential energy turns into kinetic energy the springs leaps up, throwing the soccer ball off.
4: This soccer ball, then hits a piece of wood that has a cup full of rocks balancing on top of it. “Why rocks?” you may ask. This is because we need a weight in the cup. This will be explained more in the next step.
5: The cup of rocks will fall. There are more weights, but, they are held on with velcro, ever so slightly, that even one push or tug of a heavy object will make it fall to the ground. This is where our cup of rocks come in. Once those rocks tug on the weight with velcro (they are attached by a string), the weight with velcro falls to the ground.
6: This weight just happens to be attached to a pulley. On the other end of the pulley is a few books. They were only held up because of the weight on the other side. Since this weight is no longer there, the books fall. This is not the end.
7: The books fall on a lever. A seesaw, basically. And when the books drop on one side the other side goes up.
8: This other side is wedged into a laptop screen, so then when the side goes up it opens the laptop screen.
Our changed plan:
- An RC car pushes a wedge that is on a ramp.
- This wedge is what is holding a plastic car from going down the ramp. The slightest push and the plastic car goes rolling down so when the wedge is pushed the car goes rolling down and pulls the weights with it.
3-8. Stay the same.
Why?: We decided the robot probably wouldn’t have enough power to push the car. This is because if the car is attached to the weights you have to add the weights weight and add that to the car. If you estimate that a small robot probably wouldn’t be able to push that car. But, an RC car is more powerful and, with the car on a ramp we also have the advantage of gravity, because it is easier to make it go down.
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.
- Rc car going down a ramp = potential energy ➡kinetic energy
- 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
- Since the ball was sitting on a spring board that had potential energy. Then it was kinetic energy when the weights were pulled off.
- 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.
- 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.
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.
Poems are short word groups that may sometimes convey an important message, or a regular message, or no message at all. It could just some enjoyable funny poem. This was one of those enjoyable poems. I wrote it because I decided to do something productive for once. Here it is:
Did see the moon glowing bright?
Or hear the crickets throughout the night
Did you see the sun just rise?
Or hear the hawk’s victorious cry
Did you even think to hear
The music the birds bring to our ears?
I hope you enjoyed my quick poem. And you may have seen a message which I have not seen. If it is a good one, that you think could transcend into life, remember it and keep it with you.
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 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.
