The trend in fashion are like cropped t-shirts and scrunchies. But it takes 2700 liters of water how to make a single one of those fashion trends. Non-biodegradable fabric can last in landfills for up to 200 years. Rethink how you dress and shop. You can use the online help for clean shopping! One of the main points of the article is, if you grow out of clothes every two weeks, donate your past clothes to a website to donate to homeless or clothes-less people. Making one pair of jeans is like driving 69 miles a car, so stay fashionable, yet eco-friendly!
This is not breaking news. Climate change is happening all around the world, and it’s especially affecting the fashion industry. We haven’t talked about climate change in science in the three years I have been at Hackley School. You have to be aware of the clothes that you buy. So yet again, stay eco-friendly!

People killed at least 300,000 humpback whales from the 1700s to 1950. They did this for their meat and blubber. There is now some really good news. In the South Atlantic, the population of humpback whales is now 25,000. That’s 93% of how much it was before the 1700s. In the 1700s, it was 27,000. This is happening because in the 1980s, people were banned from killing humpback whales. These new counts were done by people on ships. Humpback whales do still face some challenges.
This is breaking news. I chose this article because I love animals. The information in this article is important to the world because humpback whales are nature. This relates to when we learned about animals in first grade.

Have you ever heard of the Great Pacific Garbage Patch? It is no mountain or pile, in fact it is an area created when all the trash left on the beach at high tide gets sucked in and spit out in this area. This patch is off the coast of San Francisco Bay leading into the Pacific Ocean. This is not just some little area of trash, it is in fact one of the largest areas of trash in the ocean! This patch takes up about two times the size of Texas. And there are about 1800 million pieces of trash added to the pile each year! Yes it is true that eventually all the plastic breaks and trash breaks down, but then It turns into something called microplastics. Microplastics are little pieces of plastic that are the remains of the trash that has already broken down. These microplastics are so small that they are invisible to the naked to the eye. Therefore we cannot see them without a microscope. After that, they get stuck in other fish’s food along with turtles, seals, whales and many other sea animals. Therefore they will die because their stomachs can not break down these miniature pieces of plastic.
This article is important to me because I love sea animals and I always worry that they will become endangered. They are a very important part of our ecosystems and world. and this is not the only patch there is, there are SO many more all around the world. And this is something that has been going on for years, but the newest parts are the worst are more recent than others. Hopefully marine biologists can fix this problem so it does not continue. And that is why I think that this article is important.

This article is about cleaner shrimp. Cleaner shrimp clean dead skin off other sea creatures and eat it. The sea creatures the shrimp clean are called clients. The relationship between the shrimp and the client is mutual. The fish feeds the shrimp and the cleaner shrimp gives the fish a touch-up. Pacific cleaner shrimp, found in the Red Sea, do a dance if they see bigger fish. The shrimp dance because the bigger fish might be predators.
This article has changed the way we look at cleaner shrimp because shrimp usually get eaten by bigger fish, but cleaner shrimp don’t. I picked this article because the words under the picture sounded interesting. This information in the article is important because cleaner shrimp aren’t studied as much in the ocean.

Physicist Justin Burton became curious about bubbles when he saw some boys on the road blowing huge bubbles. He thought they were incredible. So when he got back home, he took a big bubble wand and started blowing. Scientists have been studying the physics of bubbles for a long time, and now Burton has created a new bubble recipe and can share what makes the bubbles stretch without popping. The secret ingredient is a polymer. A polymer is a chain of the same molecule made by chemically linking blocks. Burton says the polymer that’s called guar works the best for making giant bubbles. Guar also is used to thicken foods like ice cream!
The biggest bubble ever blown used guar and had a volume of 96.27 cubic meters which could fit about 13,545 basketballs inside it. What is interesting it that that huge bubble only used about one cup of bubble solution. So I’m guessing when we have a small amount of solution”,” we could use that to make very big bubbles!
Laurent Courbin, another scientist studying bubbles, said, “Polymer molecules added in soapy water not only increase the viscosity of the liquid, but also change the specific way it flows.” He did several different experiments with bubbles. For his first experiment, he tested how thick they were. To do that, he had to make a device that could create a bubble and hold it. After it was in place, he shone a light through it. It was a special light called infrared light. If they used a visible or regular light, that would go through the bubble without changing. (That is why bubbles are transparent, because regular light shines through them.) Infrared light gets absorbed by liquid. By measuring the amount of infrared light that gets through, scientists can calculate how thick the bubble is. Next Courbin did experiments on how far bubbles could stretch. They did many experiments and found that adding guar or any other form of polymers makes bubbles stretch more.
I chose this article because I like bubbles, and I also think physics is very interesting. It is important because bubbles are probably going to be a lot bigger now. The companies that make bubbles will add a type of polymer to their bubble solution, and they will keep trying to make them bigger and better. In the past, bubbles were just something to play with and not ever studied scientifically. Now, science has researched bubbles and discovered a lot about them.

This article is about how Greenland is affecting global warming. It contributes the most to global sea level rise. Greenland is surrounded by ice, and a lot of that ice is melting, therefore adding a lot of water to the sea. Almost 70% of the human population, and most major cities, are less than 100 miles from the coast. Scientists calculate that over the past 50 years, Greenland’s melting ice has added at least an inch of water to the world’s oceans, and the melting is increasing in speed. If climate change isn’t stopped, then by 2100, enough of Greenland’s ice would melt to raise sea levels by a 12 inches. Life on the coasts would be greatly affected by 12 inches of rising sea levels. Scientists are trying to figure out if the ice is melting from warm water or from warming atmosphere.
I chose this article because it is important to our world, and if humans don’t stop climate change soon, it will not be reversible. Our life on Earth will be destroyed if that happens. This article is important to science because it gives an example to scientists about what is going to happen when climate change increases.

How Antarctica is melting from above and below
Global warming is causing the glaciers to melt. The face of the ice mountains is melting into light blue lakes. Warm water rivers under the weak parts of the ice are causing them to melt. For the last ten years researchers have been studying the blue water lakes. Recently a new study was written. More research is needed to understand the harm of the lakes and rivers.
I chose this article because it is interesting to me. It explains that houses close to the ocean (including one of my houses) could flood when the sea level rises. Global warming is not breaking news because scientists have known about global warming for a long time. This article is important to science because scientists could try and figure out some way to stop the ice from melting. This information is important to the world because it will help people and scientists stop global warming. This relates to our measurement unit because the scientists were measuring how long, how wide, and how deep the lakes were.

This article is about how people have three different colors of fat in their bodies. One of them is called white fat, which stores energy through fat which is used later. Brown fat, on the other hand, burns quickly. It has a lot of mitochondria in it which burn fats, sugars, and proteins. Mitochondria are the powerhouse within cells. They also have a lot of iron in them, and that is why the fat is brown because iron is brown. Beige fat gets its color because it is white fat that in the cold weather turns beige because mitochondria starts to develop in the white fat. Because the mitochondria has iron which is brown, it mixes with the white fat cells so it makes it beige. People with more brown fat tend to be thinner than people with less brown fat.
Scientists discovered that people with more white fat tend to be fatter, and it can lead to obesity, diabetes, and other diseases. Scientists used to think that brown fat was just in animals that hibernate in the winter. They discovered that people have brown fat, too. Scientists also discovered that the cold can make people’s white fat turn beige. When fat turns beige, the fat starts to burn which can make you skinnier. Scientists are trying to figure out how to help people turn their white fat into beige fat. They also discovered that melatonin helps to turn white fat beige.
This article is about how brown fat and beige fat can help people become healthier and how scientists are trying to figure out how to do this. I chose this article because I thought that it would be interesting to learn about the different types of fat that people have inside their body and how it can help heal some diseases. This article relates to the other article I wrote about because it talks about how important melatonin is. It is important to the world and changes the way we look at old evidence because we used to think that there was only one type of fat in humans. Finding out about brown and beige fat in humans may help people lose weight. We didn’t know that white fat can change into brown fat.

When researchers started looking into the diseases that are affecting koalas, such as chlamydia and different cancers, it led them to realize that viruses are getting into the koalas’ DNA. These viruses can get into DNA and cause changes in evolution. The scientists in the article are researching a koala retrovirus called KoRV. KoRV is a disease in the same category as H.I.V. It is being passed from generation to generation in the sperm and egg cells. During the research, they found some important details by studying koalas in different regions of the world. Some koalas in the southern region of Australia have a damaged version of the retrovirus, KoRV. These animals are healthier, so scientists want to do an experiment to try to put this damaged virus in the DNA of the retrovirus, KoRV, and see if it will make the sick koalas in the other regions get better.
The KoRV retrovirus seems to be bringing back old viruses from the past that could change the future evolution of these animals. I chose this article because it is interesting that something happening today could affect the development of these animals and possibly lead to a decrease in the koala population. Hopefully by doing experiments with the damaged version of the retrovirus, the scientists will be able to find a way to fight back against the KoRV retrovirus and assist these animals to become healthier and help the population grow.

Jellyfish are soft and umbrella-shaped sea creatures with tentacles. Jellyfish have a lot of physical abilities that might teach us and help us discover things. The problem is, if we want to catch the jellyfish to do research on it, it is so soft that if we simply touch it we might damage it. Scientists created a robot that has silicone claws or fingers that trap the jellyfish, since the silicone is soft it won’t damage the jellyfish as much. Nina Sinatra is a mechanical engineer at Harvard University in Cambridge, Massachusetts. A mechanical engineer is someone who uses gadgets with moving parts to create new things. She designed a submersible (something that can go underwater) robot with silicone fingers that swell with water to trap the jellyfish without smooshing it. The robot is designed with a 3D printed palm that looks like a box. The fingers are made up of silicone which is soft and also a stiffer layer of nanofibers. The fingers have a little channel inside of them so water can flow through them, so when a jellyfish comes towards it, it can fill with water and bend to “hug” the jellyfish. In the beginning, they made the hand with 4 fingers, but then the jellyfish squeezed its way out. So to correct the problem, they added more fingers. The robot fingers use a force of a newton which is approximately the weight of an apple on the palm of your hand.
The scientists want to study the robot in the ocean, but this will require equipment that can withstand the pressure of the deep sea. They think the robot will successfully catch the jellyfish and will hold up against the pressure of the water, and its materials won’t weaken from the water. They also hope that in the future, it could include sensors and samplers to grab DNA and cameras to take photos. Nina Sinatra says that robots don’t need to be made out of hard metals or materials; they can also be made out of soft, foamy or squishy materials.
I think that the robot that ‘hugs’ jellyfish is good because we can explore the sea and find new information that we can use to help us later on. it’s also good because now people can come up with ideas to create robots in new materials that might be able to help us with a lot of new things. It teaches us that robots aren’t just big chunks of metal. We can make robots that can go on land, air, and sea that need to be gentle and not harm the creatures they are trying to catch. It doesn’t relate to anything we’ve done or learned in science.
