Rube Goldberg Post #4

Now that I am making a new machine, I need a new sketch. I used the videos to help me draw my sketch. I knew that it was a good strategy to work backwards. I tried, but I could’t really think of how to tip over the cup of food. Then I decided that I’ll just work form the beginning. I thought that it would be really hard, but it was actually pretty easy.
My first step is me pressing the button. The button then makes the car go on the track. Then the car will hit the clear tube. There is a paper role that has a string tied to it. On the other side of the string is a little tire. The tire on the string is wrapped around the paper role. The clear tube stands next to the tire to keep it from swinging. When the tube falls down, the tire on the string swings. Then the tire hits the dominoes, which hit each other. The last domino has a string attached to it. The string is also a stopper for the marble on a ramp. When the last domino falls off the table, the string goes down with it, causing the marble to go down the ramp. Then the marble shoots the ball and knocks down the cup of food.
I hope that this will work.

Rube Goldberg Post #3

When I was testing my Rube Goldberg, I realized that it didn’t work well. The track was sliding, the car wasn’t going around the loop. It just wasn’t reliable. I was really upset because I worked pretty hard on it, but I knew that my machine had to work almost all the time. I had to be reliable.
I didn’t have many more ideas, so I looked at some examples of Rube Goldberg machines to help me out. The video helped me a LOT. It gave me many ideas. Then I had to sketch it. I took some parts that I might need to make my new ideas work. After some hard thinking and testing, I finally had a poster of my new Rube Goldberg machine.
My goal is to make the food in the cup fall in the dog bowl. Then my puppy, Sierra will eat her dinner. I have 13 steps.  Now that I have all of the parts, I will start to build.

I finally decided what I was going to do. I don’t know exactly what my goal is, but I have a pretty good idea. I already know almost all of the steps and my sketch is almost done.
The first step is that I press the button. That causes the car to go around the track. Then the car hits the cup, which makes the ball fall out. Then the ball hits 2 small balls. Then each ball hits a domino, which hits more dominoes. Each path of dominoes leads to a different step.

Rube Goldburg Post #1

Kids in my class are working on a Rube Goldberg project. Some kids are working in groups, and some our working solo. I am working solo. Many people like to work in groups, and so do I, but I chose to work alone because it would be easier to focus and get work done.
It took me a little while to figure out what I was going  to do since I was on vacation for a little while. Most people had already decided who they were going to work with and what their goal would be. I on the other hand didn’t even have  good idea of what we were supposed to do.
Since I already was kind of behind, I thought that it would be best to work alone and not have to worry about scheduling.

Reflection on Rocketry Presentation

Today we presented our rocketry presentation. I was so nervous, I had butterflies in my stomach. I couldn’t believe that I had to do the overview and my group’s presentation. . I’ve never had to give big presentation like this and I was worried that I was going to totally mess up.
When I finished the overview, I was relieved. It was very scary, but it wasn’t as bad as I thought. Then I got very confident for my big presentation.
It turned out that the big presentation was a lot harder. I still got through it, but we all stuttered once or twice.
Giving the presentations was really fun, but I’m glad it’s over because it was hard and nerve-racking. It’s too bad that I still have to do the overview again tomorrow for part 2 of our share.
This is our presentation:

My Colonial Book Reflection

I had so much fun making my new Colonial America Book. I enjoyed researching colonial battles between the Native Americans and the Colonists. It was also fun, but challenging, formatting and fitting everything in my colonial book. I had a great experience.
I did the same topic as Noah, but in the end, the two presentations came out pretty different. Check out his book.
When I researched, I used 2 books and one website. I read the book, Blood On The River By Elisa Carbone and The Real Story of The Weapons and Battles of Colonial America by Kristine Asselin. The website that I used was
