We don't accept negative vibes here move along.

Drop 1

In Project Collisions, I am creating a system to deliver first aid kits by drones. The drone will release the package from a height up to 10 meters and my job as an engineer is to develop a solution so that the package is protected in its fall.

For Drop 0, a package with the dimensions of 22 by 26 by 7 was dropped from a height of 5 meters. Below is a photograph of the package:

The package will hold:

a first aid kit with alcohol pads, band-aids, bandages, cotton pads, medical tape gloves, a mask, tweezers, a mini blanket , and most importantly instructions, items are organised like this:

<insert image of your drawing of the inside of your package>

The purpose of Drop 0 is to get baseline data about our package. The group developed a testing procedure so that we can be consistent on how data is collected throughout the design cycle.

Since I wasn’t there during the drops, my teammates noticed that most of the time the delivery package hit the force plate, it would always hit the sides or the corners of it. The following Data was collected:

 

The average time it took for our package to fall the 5 meters was about 1 sec. Using LoggerPro, we plotted out the fall of the package.

After the Package fell, it kind of hit one corner of the force plate and bounced off.

A force plate at the bottom of the drop was used to collect data on the impact force of the package. Our group was kind of successful in terms of accuracy, because out package landed on top of the force plate only leaning a little to one side, but if did not fall of onto the table. As a project metric for accuracy, we want our project to land as close to the target as possible, because in some cases the person in need might not be able to get near the med kit if it is at a far distance or got stuck in a tree.

The average force on impact was about 120 N.

 

As a project metric, our group has decided to build a parachute big enough to reduce the force by 25%.

Summary: Project Metrics

Our team has decided that the three most important criteria to design towards accuracy, velocity and force. Below, each metric is described, and the goals were determined by data from Drop 0.

  • Accuracy: The distance in cm from our target + within 10 cm of the force plate
  • Velocity The speed of the fall + 50% velocity reduction
  • Force: How hard it hits the ground + we want to try reduce the speed by 25%

 

 

Our group is now building the first prototype. I hope that using a parachute won’t reduce accuracy and just float away.

Project Collisions: Blog Post #1

On Monday, January 7, I began Project Collisions with an egg drop. This design challenge was to drop a raw egg from a height of 5 meters without breaking it. A material list with items to purchase was provided. My First Design was to attach many crumbled paper balls around the egg out of A4 papers and I wanted to put a parachute on top but I decided to get balloons instead which wasn’t a very good Idea.

Then, working in a group we decided to put the egg into a balloon with crumbled up newspaper and A4 papers, but however the egg didn’t fit the balloon so we had to change our whole plan. Our second design was just to wrap the egg with many layers of crumbled up newspapers and surround it with straws and plastic little army men. The balloon we had was basically useless to us, so we just tied it to the top.

As the egg was dropping , I didn’t know what to think, because I was scared and I didn’t know why.
I already knew that we’ve messed up because our first design failed because we had to quickly put something together to launch the egg drop.

And our design was unsuccessful because the papers that we put around the egg were too thin so the egg fell right to the ground and cracked.

Next time, I would try making a big parachute for my egg because I saw other teams try it and some of them actually succeeded. And the reason why I think so is because the air pushes the parachute back up, and creates a force opposite to the force of gravity, slowing the object down when falling.

Project Collisions is using the idea of drone delivery. During my research, I found out that some people needed to find a faster way to deliver.  For example people who are in need of blood and fast, thats why a blood and other medicine donating company called FlyZipline started using drones to deliver blood and vaccines to nearby hospitals and homes.

Through out this project, I hope to learn how to safely deliver an egg from a 10 meter fall.

Stories of da future review

Looking back on Stories of the Future, I learned that we won’t have a very pleasant future in 2050, because we all are going to die .There are many  problems because of the overpopulation: we will be suffering from global warming, environmental pollution, habitat loss, Holocene extinction, lack of space and natural resources such as fresh water and others. For example, in humanities we talked about what it would look like for a ten-year-old to live in the year 2050. We wrote a story about what we think that will happen and presented it to the 4th and 5th graders.

In Science I learned that our bodies need energy to survive and we get energy from oxygen and nutrients that go into our cells (through our blood streams) and turn it into energy. We get oxygen by breathing air and nutrients by eating food. For example, Glucose is a nutrient that carries energy in their bonds and once it breaks, it releases lots of energy inside our cells. For example, in the science investigation, TITLE, we measured our heart rates while doing different exercises. The results showed that as the intensity of exercise increased, so will your heart and breathing rates. Before this project I used to think that all the difficult problems will be solved by 2050 and that everything is going to be ok, but now I think that we are all going to suffer and die because we won’t solve food and pollution problems. For example, a lot of people won’t get enough food and starve to death. the people who will have food, will get food poisoned because of the plastics that float around the sea and get eaten by other animals. 3. I think that we are also going to run out of space to live and grow crops. We are going run out of water and die.

Looking back, I am worried about the future. But I also grew as a scientist, because I learned how to model, write claims and supporting evidence to make it believable.

Lol..

 

 

What? So What? Now what?

What?

A huge  problem we will be  facing in 2050 is the growing population. And that is because according to the article ” Overpopulation Effect – Everything Connects”  we will be suffering from global warming, environmental pollution, habitat loss, Holocene extinction, lack of space and natural resources such as fresh water and others.

So what?

And since our population is at 7 billion and continues to grow, soon enough by 2050  we will be at 9-10 billion. Overpopulation will create revolutions and civil wars, which in turn will produce a constant flow of refugees.

Now what? 

One thing you can start doing is to save water and food, and try recycling plastics?

Stories of the Future: Day Zero

  1.  What are the three most urgent problems that need to be solved by 2050?
  • Overpopulation
  • Global Warming
  • Plastic recycling

2.    What are two wonderings or questions you have about the future?

  • I am wondering what the year 2050 look like?
  • What are we going to do against global warming? How are we going to solve global warming?

3.  Do you have an optimistic or pessimistic view of the future?

  • Pessimistic

4. Looking back on today…..

5. How do water, food, and communities connect?

  • Population grows
  • running out of space
  • water pollutes, air pollutes
  • running out of clean water
  • running out of resources

6.      I used to have a pessimistic view of the future, but now I am even more pessimistic about the future because if we don’t solve                  any of these problems, we’re going to die. We’re going to be running low on clean water because if the air pollutes the water                    pollutes and if we run out of clean water there will be no clean water to grow crops and  if we want to grow crops we need a                      more space,  to feed the world, and that means less space for the people and because the population is growing we are slowly                  running out of  space and soon we will all be squished on tiny planet  called earth.

Make It develop and Plan

Today we made our prototypes out of cardboard, Ivy and I were very excited to finish our prototype we were so looking forward to making it we have our paper prototype all planned out and we also wanted to create this super cool marble effect on the iPhone case.

 

marble effect

our iPhone X prototype

 

But as we were trying to get the shapes right over and over again we got very frustrated we realized that making an iPhone case was way too hard to make so I came up with another idea.

I decided to create a tissue box. I completed the prototype out of cardboard. I used hot glue to glue the sides together and then used black masking tape to decorate the outside. I realized that there were other students creating this exact product, so I want to change my final product. 

I’m going to make a small and simple desk organizer for my family. But I think that I won’t be able to finish my final project because I only have one more day left. And I still have problems with gluing the parts together so I have to do my best and try to finish my final product.

 

My second sketch prototype
