Testing

Hello, for the next few months, I will be updating my blogs on photos I have been taking during my ELO trip ( Beijing Through the Lenses ). I am looking forward to have lots of fun and at the same time improving my photography skills.

Reflect & Share

Give an overview of your design process, sharing the product & your learning.

We were happy with the outside appearance of our prototype. This is called an ornithopter which is meant to show the energy conversion between elastic potential energy and kinetic energy. The wing gets the signal to flap when the user rotates the propeller to the connected rubber band, and when the user releases it, the energy transfers into kinetic energy resulting in a movement of the prototype. One scientific thing I learned about this prototype is that it was pretty cool how just using a small rubber band would help the whole toy to function and fly for so long, which made me wonder if almost all of my house toys needed energy conversion to function well. Furthermore, I also learned that being careful in all the small details is really important while doing these engineering projects. Where every measurement, material, size, tool, etc could affect any small parts of the product, which then would affect the big results and may lead to not reaching the expectations you want.

Use the rubric & your own success criteria to discuss the strengths and weaknesses of the product.

Looking at the rubric to assess myself, I think overall we did a pretty good job. Our prototype does satisfy the success criteria but only two out of three. As written in the previous blog posts, our success criteria were…

-The ornithopter should be able to fly for at least 7 seconds 

-The ornithopter should be able to flap its wings successfully 

-The quality of the ornithopter should be able to hold up to 10 trials without breaking down

Our prototype was able to flap its wings successfully and was strong enough to hold up to 10 trials without breaking down. But one weakness of our product is that even though it was able to flap successfully, only one wing was able to do that, thus our prototype wasn’t able to actually fly into the air at all which. 

Explain how and why your toy/device meets the design specifications.

Our toy definitely meets the design specification because it shows clear energy conversion of elastic potential energy and kinetic energy. From the expectations we gave, the toy does have a pretty cool and creative appearance which we wanted it to have to draw the attention of the kids and many other users. Furthermore, our toy is also environmentally friendly as we decided to not use any plastic and instead used wood, sticks, and paper, which are materials that could be renewed and are biodegradable to the environment.

Other reflections: What are you most proud of? What was most challenging?

One thing I’m really grateful for and proud of is my partner and I’s teamwork and communication through building this hard and high technique/skilled toy. There were times when we wanted to give up on this project and start a new and easier one, but the patience and positive mindsets my partner and I had grabbed us from the “I give up” mindset and actually worked out pretty well. Even though the prototype couldn’t function well, I’m still really proud of the effort and strive my partner and I had put in to finish building this toy. The most challenging part of this unit was definitely building the toy. There were a lot of small parts of the building process that needed highly skilled techniques to make the mechanism work, so we need to do everything step by step and not mess up on any of the steps. One specific challenge I remember was drilling a small hole into the small wooden sticks, where these were to connect the wires to the propeller and so we had to make sure the hole wasn’t too small or too big. Due to the thin and tiny wooden stick, we needed to be extra careful when drilling, and when the hole was too big or small, we had to do the steps over and over again which was really challenging.

Create & Improve

Reflect on your prototype. What were some strengths? What needs refinement?

Our prototype overall came out pretty to what we expected from our plan and blueprints. Some strengths I thought were that the toy was able to show the obvious energy conversion (elastic potential energy to kinetic energy) and at least one of the wings was able to move successfully. Another strength was that our toy was actually really built from the wood material we used, it was stronger enough to hold and so I’m guessing if the two wings worked out correctly, it may fly into the air successfully as well. However, some parts that would need refinement was the propeller and the wings. The reason we thought of why only one side was moving successfully was because of the connection between the propeller and the wings, this might be because of the detailed steps we didn’t consider or because of the different materials we had compared to the original video.

Outline the feedback you received from peers. Share some changes you will make as a result of this feedback.

Some feedback we received were:

Strength:

“I like how your design looks like a peacock. I think it is really colorful and attracts young people.”

“I think the design is really creative.”

“The envision is great and the idea is pretty solid.”

“I like how you guys used duct tape to wrap around the pointy end of the stick.”

Improvement:

“One thing you guys could improve is the appearance. Even though the toy looks really good, but the combination of the glue and strings that were used to connect the bent wire with the wood piece created a big lump, and so it might make it look not really aesthetically pleasing.” -Adding on to this feedback, one way I thought of improving was to firstly change the materials (but also needed to carefully consider if changing the materials would make an impact or not). Then because the glue created a big lump, next time we could try using super glue or adding less hot glue to make it look a bit more pleasing.

“I wonder if you could bend the paper clip again and so that it will be in the opposite direction to the existing one, then hook up the wings, and see if it would move.” -Adding on to this feedback, I think this could probably work. Bending the paper clip again may stop blocking the connection between the propeller and the wings and so that it could rotate successfully.

Develop & Plan

Define and Inquire

What is the purpose of your device/toy, how does it function, and who is your user? 

My partner and I decided to build a peacock-flying ornithopter as our toy. The energy displayed by this toy is elastic potential energy that transforms into kinetic energy. The ornithopter’s ability to fly results from the elastic band’s ability to gain potential energy when it is twisted by the rubber band because it is connected to a spinning propeller that is attached to the toy’s wings. Our user of this toy is mainly for around the age of 7-14 kids; as my partner and I carefully considered about the safety concerns and if it was easy or hard for them to function with.

What is the environmental impact of your product and is it durable and safe?

Since wood is renewable, the majority of our materials are also environmentally beneficial. Unlike other building materials (like steel, plastic, metal etc), wood doesn’t deplete the resources that nature offers.  Wood is a resource that can be continuously grown and collected because it essentially stands alone. But, because our toy is made of incredibly lightweight and delicate materials, our toy most likly to become less durable. Nonetheless, this then results our toy to be extremely safe because it doesn’t have any sharp ends that would harm its users, and also because of how light the ornithopter weighs.

What precedents inspired you? What did you take away from them & how did it inform your choices?

The various flying toys that were created on YouTube gave me the inspiration. All of these toys gained elastic potential energy in order to be able to fly, which I thought was really interesting and wanted to try if it would work for my product.

How are you making your product original and/ or using creativity?

We kept the product original as we changed some of the materials they used. For example instead of cutting plastic bag for the wings, we used paper to keep our product more environmentally friendly. On the other hand, we made our toy look more creative by making our ornithopter into a peacock, which we believed may draw children’s attention to and interest them in our toy more.

Mood Board: Exploring Themes for Scenic Design

My mood board represents a type of phobia: fear of being alone. The term for this fear is autophobia or monophobia. For someone with this condition, being alone, even in a typically reassuring environment like home, can cause intense anxiety. People who suffer from autophobia or monophobia believe that they need the company of another person or groups of people in order to feel secure and comfortable. I paid thoughtful consideration to the color, emotion, background, or setting of each of the 30 photographs as I looked for them in order to find ones that would best express my phobia to the audience. As you can see, my overall first impression of the theme or mood of my board is probably depressed, lonely and/or dark, etc.

Marine Pollution

Introduction: 

Today, many environments are being polluted by humans across the globe. If I asked right now, I’d estimate that more than half the people on the street would know about marine pollution. Why? Marine pollution is a type of pollution that terribly harms marine animals through daily human actions. Today’s world sees a big problem with marine pollution, which is problematic as this not only harms the marine environment but makes a massive impact on our lives as well. 

 

What Are Some of the Cause and Effects of Chemicals and Trash? 

Marine pollution has five causes: the main two being chemicals and trash. According to Important India, among the major polluters of the world’s oceans are plastic bags, aluminum cans, trash and other human waste. Recent discoveries found a massive trash island piled up together near the Pacific Ocean, which shows the severity of the problem. Based on information from Important India, trash and littering are known to hurt animals by choking them. Marine animals, like fish and turtles, are increasingly dying from choking on trash or being unable to digest it–plastic has been found in their stomachs on a regular basis. Another cause of pollution is chemicals. There are two different ways chemicals can get into the ocean. First, when it rains, chemical compounds get washed into rivers, where they are carried to waterfalls and eventually end up in the ocean (Espinoza). The second way is through industrial processes (Sensorex), for instance, lead, oils, phosphates, asbestos, nitrates, and petrochemicals. As a result of toxic chemicals, our oceans are becoming more acidic. These toxic substances harm marine life like fish, marine mammals, and marine plants and corals as well (Important India). In addition, they can reduce oxygen levels. Seawater is full of dissolved oxygen, however decomposing sewage and other biomatter in oceans can result in a condition known as ‘hypoxia’ or oxygen depletion. This makes it hard for oxygen loving marine life – plants, fish and animals – to survive in the ocean (Important India).  

 

Ways We Can Solve This Problem! 

As time passes, the ocean becomes more polluted by humans, which leads to the death of almost one million marine animals every year (Sea Turtle Conservancy). Therefore, we must act quickly to minimize future deaths of marine animals. A few solutions were provided by Oceanic Society, they talked about a few points for us to help solve the marine environment from getting polluted.  

Reducing Your Use of Single-Use Plastics 

Using single-use plastics, such as bags, water bottles, straws, cups, utensils, dry cleaning bags, and takeout containers, could be reduced. As an alternative to single-use plastics, there are two ways. One is to avoid using single-use plastics and two is to purchase and carry reusable versions. These would include reusable grocery bags, produce bags, bottles, utensils, coffee cups, and dry-cleaning garment bags.  

Recycling  

Recycling single-use plastics whenever possible. Not only does this reduce the amount of plastic getting into the ocean, but it also helps to clean the marine environment by removing debris. Swimming in the ocean becomes more conductive as a result, as no plastic will get in the way of swimmers, prevents animals choking from plastic, and the ocean does not become polluted with plastic particles.  

Staying Away from Microbeads 

The ocean has become a more polluted area due to tiny plastic particles called microbeads. Our sewer system allows microbeads to easily enter our oceans and waterways, and they have an adverse effect on hundreds of marine species. Microbeads can be found in face scrubs, toothpastes, and body washes. We humans can help by using items that do not contain plastic microbeads which prevents microbeads from entering the marine environment.  

Participate In Activities That Help Clean the Beach or River 

Participate in, or organize, a beach or waterway cleanup in your locality to prevent plastics from entering the ocean. A direct approach to reducing ocean plastic pollution is one of the most rewarding. A simple cleanup of the beach or waterway can be done on your own, or you can participate in an international event, such as the International Coastal Cleanup, or you can simply collect plastic waste on your own. 

 

Why Should We Help? 

We should help because first oceans support life on Earth since they’re the largest ecosystem on the planet. Because the ocean is so closely interlinked with the earth’s other ecosystems, if the ocean becomes polluted, it will affect not only marine life but also plant life and human life (Marine Conservation Institute). Another reason why we should care about marine pollution is how it influences the weather and climate. “The ocean absorbs about a third of carbon dioxide produced by humans… [and] also buffers us against the worst fluctuations in climate, by directly absorbing heat (Mustoe biog).” So, without a healthy ocean, the air we breathe everyday will be affected and climate would become more unstable. Ultimately, we should do the right thing protect our oceans, our animals, and our ecosystem.  

 

Conclusion: 

Chemicals and trash affect the natural environment negatively. Each year, millions of marine animals and seabirds die from marine pollution. With people all starting to help the environment, together we can make a whole new healthy environment for marine lives and ultimately ourselves, “Even the largest avalanche is triggered by small things (Vinge). ”

7 solutions to marine pollution

Marine Pollution. www.nationalgeographic.org/encyclopedia/marine-pollution/.

-the ocean is being flooded by 2 different pollution: chemicals and trash

-they come from land source and is often blown/washed to the ocean

-the increased concentration of chemicals, such as nitrogen and phosphorus, in the coastal ocean promotes the growth of algal blooms, which can be toxic to wildlife and harmful to humans

-fishes become tangled and injured from the trash, and some animals mistake items like plastic bags for food and eat them.

-solutions to marine pollution include prevention and cleanup

-disposable and single-use plastic is abundantly used in today’s society, from shopping bags to shipping packaging to plastic bottles

-cleanup after yourself, don’t throw trash everywhere

-more than sixty countries have enacted regulations to limit or ban the use of disposable plastic items

common causes

human, litter and human waste:

plastic bags, aluminum cans, trash and other human waste constitute a major pollutant of the world’s oceans. a huge ‘island’ of trash roughly the size of Texas was recently found in the Pacific ocean for instance, demonstrating the vast scale of this problem

dissolved greenhouse gases:

greenhouse gases from human fossil fuel consumption are making the sea more acidic

 

effects of marine pollution

oxygen depletion-makes it hard for oxygen loving marine life plants, fish and animals to survive in the oceans

higher acidity-toxic chemicals would make our oceans more acidic, this poisonous marine life and harms fishes, marine mammals, marine plants and corals.

choking marine life-small pieces of plastic and other litter were found in the stomach of animals

spoiling birds feathers-oil spills coat the feather of the marine birds, as a result they would find it hard to stay afloat as their feather get soggy, and they would also find it difficult flying since their feathers are full of oil

dangers to human health-human swimmers and water sports lovers can become endangered by swimming in a polluted sea

-marine pollution affects more than 817 animals species

-plastic is one of the most common causes but their are more

-waste we produce on land reaches the ocean by: littering, oil spills, toxic chemicals agricultural runoff, ocean mining, etc

-these effects the animals and us humans for example: depletion of oxygen content in the water, effect of toxic wastes on marine animals, failure in the reproductive systems of marine animals, contamination of the food chain, effect on human in heath, disruption to the cycle of coral reefs

-some ways you can prevent trash washing in the ocean are: picking up trash and properly dispose it, reduce reuse recycle, educate people around you tell them whats happening to the oceans by the actions they make

My Mexican Revolution Journal 1910-1920

In this project, we were told to write a journal based on the revolution we chose. We had to have 3 entries that shows the 3 main/important dates during your revolution. I hope my journal would give you an image on important events that happened in Mexico, and how the revolution affects the people and its country.
