The Video below is part 2
Fake or real, that’s the question. News about dogs transmitting the coronavirus actually makes a big impact on owners, shockingly some pet owners abandon their pets or even kill their pets. Found out more by watching the short video.
I wonder how we will film the kind of ad like video and another wonder is if we have enough time to do this, since filming can be a bit hard since we are separated and also if we separately film and the file is too big to send then that is a problem.
I feel like that one way to engage our audience is that the introduction has to hook the viewer, or else the viewer may not be interested, another way to engage the viewer is to pop out facts that make viewers feel shocked and surprised, another way we might use is to give information to viewers so they can learn new facts.
My biggest fail for this project was accidentally starting the whole chain reaction when I did not want to. The problem was that I had to be very careful not to knock down the dominoes or a marble, but I learned from my mistake and stopped the problem, instead, I used a blocker so whenever I start a new section I use a block and place it between dominoes so they don’t knock down. In the end, my project was successful.
My original goals for today was to finish building and finalizing The Cereal Machine first, then record the machine and fix any mistakes during the chain reaction, and possibly start making the video for the exhibition.
My challenges for today was that I had problems with the video, when I imported the video everything seemed fine, but when I realized that the video somehow skips a small part I knew that the clip or Imovie happened to it and skipped. My other problem is that when I imported the video I had already cleaned up the area where the contraption was, so if I wanted to re-record I would have to restart all over again.
A goal for tomorrow is to finish editing the video I am preparing on Friday.
My original goal for today was to start building the ramp and fix any loose or unstable ramps, and if I finished
the wall-mounted section I can possibly start a bit of the section on the floor, after building just 1/2 of the contraption I will work on Blog Post 3.
Some challenges I face while I was building was that sometimes I would accidentally knock over dominoes on accident and everything would fall down, but then whenever I was working on a new section I used a cube to block dominoes from tumbling if I accidentally knock some down. Another challenge was space, I originally thought that I wouldn’t have enough space, but once I figured out that I had even more space.
Today I started the wall-mounted Rube Goldberg contraption and also the contraption on the floor, and almost finishing the whole contraption, tomorrow I can finish building the contraption and start finalizing the contraption, and possibly film the contraption.
I am trying to find out ways to make a successful Rube Goldberg contraption with the materials I am limited at my house and to do so I am going to test different objects that I could use in my contraption.
Some challenges I will face is the lack of space, I only have access to the 3rd floor of my house but only 1/3 of the floor, but it might not be enough to set up the Rube Goldberg contraption, so I might have to simplify my idea later on. Another challenge is some materials, mainly I am lacking tracks for my marbles to roll on, so I will keep finding more materials I can use to make some tracks.
Some hopes I have for this project is that I hope that I will complete in time and run the contraption successfully, this means that I would have to keep testing and testing so that when I do the final test it will be successful, I also hope that while I am building I can maybe add on to my original plan so that the contraption is more interesting.
What is a Rube Goldberg Machine?
A Rube Goldberg machine, named after American cartoonist Reuben Garrett Lucius Goldberg, is a machine designed to perform a simple task in an indirect and overly complicated way. Usually, these machines consist of a series of simple unrelated devices, one example could be the pulley. The pulley can change the direction of force, for example, one side of the pulley would be heavier than the other side will start moving up, in this case, the weight of the object is a marble. Usually, a Rube Goldberg machine has a goal, the goal could be getting the marble from point A to point B, or it could perform a simple task.
The Rube Goldberg machine was named after the American cartoonist Reuben Garrett Lucius Goldberg, best known as Rube Goldberg. Rube Goldberg was born in San Francisco (July 4, 1883) and died in New York in (December 7, 1970). Rube Goldberg’s cartoons were based on complicated gadgets that could perform simple tasks indirectly. Goldberg is the inspiration for international competitions known as Rube Goldberg Machine Contest which challenges participants to create a complicated machine to perform a simple task.
This picture is an inspiration of what I might want to do, this shows a Rube Goldberg machine mounted on a wall. I chose this picture as an inspiration because I really like how not only does it look simple but I like all the elements on this Rube Goldberg contraption, but I would like to make a few changes to some tracks and extend the Rube Goldberg machines with dominoes, more chain reaction, etc.

As Project Collision shifted due to the Covid-19 virus from a collaborative school project to an individual home project, a big challenge that I faced was finding the right material for my parachute, this was a very large problem considering if I did not find the right supplies for my parachute it could have affected my data I was gathering. To overcome this challenge, I found some of the supplies that were required for my parachute, at first, I thought that I did not have enough, but when I finished building, I still had so much left.
Before this project, I used to think that I would not finish in time due to the Covid-19 virus and also the lack of time due to the holiday, but now I think that I am on a good track keeping up with everyone else in my group and I feel more confident. For example, I thought that the Blog Posts were going to take up a lot of time and take out the time for building the parachute, but in the end, I managed to handle the Blog Posts well and could keep up with my group.
Looking back on Project Collision, I learned that collecting multiple pieces of data is important during this process. For example, if you are trying to find accurate data testing numerous times and finding the average makes your data more accurate. One area where data supported my thinking was, although the speed increased a bit the accuracy seemed like it was getting better as the parachute size increased, and my data set in my data table supported my thinking.
Project Collision 5
Although it has been quite a challenge, for example, school is still temporarily closed due to the coronavirus, I managed to solve all my problems lately. Our company, Technical, promises fast and efficient delivery. Within your package you will receive tech accessories that you have ordered, we promise our products will not get damaged in the process. To ensure that the package is safe, my partner and I are building prototype parachutes to test which size the parachute is the best for landing softly and accurately. Our goal is to drop the package within 50cm close to the target, which we have conducted several tests at home.
The items held constant in the trials were the material of the string, the length of string and the material of the parachute. The material of the string was yarn in substitute for the fishing line, the material of parachute was LDPE plastic which we decided was a substitute for nylon. A change in our design iterations is the size of the parachute which my partner and I have decided the parachute size to be 38cm, 48cm, and 58 cm in diameter.
The bottom parachute is the 58cm parachute in diameter, the constant is the strings and the material of the canopy, I did not really have any challenges during the production process. The parachute at the top is 48cm in diameter the material is also the same as the 58cm parachute, again there were no issues during the production process. The 38cm parachute is the parachute at the top, the parachute canopy was not transparent but still, the same material and the strings were not yarn but a substitute for yarn. For this first design, I had some trouble finding the right type of string but eventually found some. I thought my sister did not let me use her yarn when I made the parachute, but after persuading a lot I got yarn for my second and third designs (48cm and 58cm).
This data table includes the size of the parachute in diameter, (38cm, 48cm, and 58cm) the speed of fall in meters per second, the three trials, the averages and medians from the drops, and the accuracy of the fall (Left, Right, Center)
A challenge I faced with the drops was if my trials were accurate, so I had to re-test a lot in order for my data to be correct. A positive from my drops was that I had enough materials for my drops. If I ran out of LDPE then I would have had to either use another type of material or just restart and test with another material. For the 38cm parachute the average was 1.67 m/s and the median was 1.68 m/s, the average for the parachute that was 48cm was 1.31 m/s and the median was 1.35 m/s, the average for the 58cm parachute was 1.32 m/s and the median was 1.26 m/s. For the drops for the 58cm and 48cm parachute, there were some outliers in the data set, the data set from the 58cm parachute was 1.05, 1.26, and 1.66, the minimum and maximum are both outliers. The data set for the 48cm parachute was 1.4, 1.17, and 1.35, the minimum and maximum are also outliers. The reason that there might have been outliers might have depended on when the parachute deployed, because when the parachute is deployed later in the drop the speed will increase, but if the parachute deploys at the start the speed decreases.
Evidence:When I started testing my first parachute, I realized that the parachute did not land anywhere near the target. Since the spill hole lets the parachute land more accurate by letting some air through the hole, but still landing slowly. This reflects it might have meant the spill hole was too small, so that it did not land that accurate. When I tested the 48cm and 58cm parachute I realized that it was much more accurate when it dropped, when I started testing both they were starting to land within the 50cm range.
Trial 1 = Left/50cm Trial 1 = Center/50cm
Trial 2 = Center/50cm Trial 2 = Center
Trial 3 = Center/Right Trial 3 = Left center/50cm
Reasoning: The reason why this could be happening is that the spill hole increased during each build, so the accuracy got better. This relates to Newton’s 3rd Law: For every action, there is an equal and opposite reaction. For example, since when I added a parachute to the box, the drop velocity decreased. This meant that when the parachute dropped the air resistance was letting the parachute drag or slow down, the spill hole is to let the air resistant pass through so not only does it drop slower, but it becomes more accurate when the box drops.
