Q2First of all, something dense than water sinks such as metal and something less denser than water floats such as air but how does a boat made of metal float well if an object is heavier than the amount of water that is displaced or is something that is very dense the object will sink like the bowling ball and if the object is lighter than the amount of water it is displaced or something not very dence the object will float like a boat so if we put the grain on the boat, it will be less dencer than the water, therefore science has solve the problem of how to get the wheat over a large river

https://www.youtube.com/watch?v=nMlXU97E-uQ

the problem that Science have to solve is why do things sink and float

PROBLEM:

the problem is addressed as that boats made out of metal is a lot denser than the density of the water, making it nearly impossible for the ship to float. Concluding, that we couldn't have the needs that are shipped across sea, in order for our health.

SOULUTION:

the principles oof this problem is density, every thing has a density, depending on their material, in order to solve this problem, we have to know what the waters density is, And if the density of the thing is less than the water, the thing will float. take a cargo as an example, the density of metal altogether is more than the density of the water, making it sink, but while the cargo is mostly made out of air, that makes the density less, and that is why a ship will float. A second thing is that the floating ability is often called buoyancy, it will make other things float. while that is there, the boat contains lots of that, witch causes the water level to rise, and causing the boat to flow equally.

when boats con't float, I can cause us a lot of problems for us, like, not having the needed needs we need I our life. Not to mention how we can travel across the waters, aside from air planes. therefore, a floating boat is really important

Why things will float and sink on water is based on its density, if its density is greater than water, the object will sink, if else, it will float on water

1. What problem has science been used to address?

   people need to travel using ships. 

   The problem is they think ships is so big and will sink but in the en they put a lot of air to make the ship float  

2. Identify and summarize the scientific principles that have used to solve the problem.

The video tells us that normally if the thing have less mass it float and if it have more mass then it will sink but for boat it has air in it so it will float

COLD.

1. What problem has science been used to address?            the problem is what happen when people get cold?

2. Identify and summarize the scientific principles that have used to solve the problem.

   we found out that our cloth has some material that can keep us worm

   
   

1. Discuss how science helps us not to feel cold.

   Answer:According to Christopher Minson, a professor of human physiology at the University of Oregon, there is hope. “Absolutely, people can adapt progressively to cooler temperatures,” he says. “Humans have become very thermostatic. We go from our perfectly heated or air-conditioned house to our perfectly heated or air-conditioned cars to our perfectly heated or air-conditioned work.” This, he believes, is not healthy. We’re not exercising the mechanisms we use to keep warm, and our perception of acceptable temperatures has become unnaturally narrow.

   Essentially, says Minson, humans are big bags of water and meat. “What keeps us warm, really, is our metabolic rate: how much energy we’re producing.” But there are physiological differences meaning that some have to work harder than others to maintain their core temperature.

   “Men in general are going to have a bit more muscle mass than women,” says Minson, “so this helps them stay a little warmer.” This is because having more muscle increases your basal metabolic rate – your capacity to burn energy from food. It helps explain the modern phenomenon of “sexist” office air-conditioning, whereby the temperature is perfect for most men, but chilly for most women.We put our bodies under immense strain while training for and competing in trail races and ultramarathons. Time and again, our bodies exhibit what can only be described as remarkable adaptation to that strain. Many of these factors are environmental in nature, such as heat and altitude, both of which we’ve written about at length in this column. But what about the cold? Do humans have specific ways of handling cold weather? And what does that mean as you tackle cold-weather training and racing?

   The answer is yes, we do adapt to the cold! Well, to a degree. In this article, we explore what the scientific literature knows about how the body reacts and adapts to being in cold environments. So, grab those hats and mittens and let’s get out there! 

   When compared to other mammals, humans are pretty maladapted to surviving and thriving in extreme and/or chronic (prolonged and/or repeated) cold. Yeah, that’s a fairly grim start, but nevertheless humans have developed numerous behavioral and physiological adaptations to mitigate cold exposure and to thermoregulate as needed. This means maintaining thermal balance by reducing how much heat is lost to the environment and by increasing heat production within the body

2. I think science can make some materials that can make us warm.

   Answer:A new fabric created by a team of US scientists could be used to cool or warm up its wearers depending on how hot, cold or sweaty they are.

   The material has the potential to create clothing for sports from running to alpine skiing, which adapts and keeps people the ideal temperature.

   When conditions are warm and moist, the fabric allows heat to pass out, and when conditions become cooler and drier it reduces the heat that escapes.

3. How science can make, and another thing is how to find a materials?, and maybe the materials will be expensive.

   Answer:Both the global research community and federal governments are embracing a move toward more open sharing of the products of research. Historically, the primary product of research has been peer-reviewed journal articles and published technical reports. However, advances in information technology, new 'open access' business models, and government policies are working to make publications and supporting materials much more accessible to the general public. These same drivers are blurring the distinction between the data generated through the course of research and the associated publications. These developments have the potential to significantly enhance the value of both publications and supporting digital research data, turning them into valuable assets that can be shared and reused by other researchers. The confluence of these shifts in the research landscape leads one to the conclusion that technical publications and their supporting research data must be bound together in a rational fashion. However, bringing these two research products together will require the establishment of new policies and a supporting data infrastructure that have essentially no precedent in the materials community, and indeed, are stressing many other fields of research. This document raises the key issues that must be addressed in developing these policies and infrastructure and suggests a path forward in creating the solutions.

2: the scientific principles that is shown is the change of density. Since everything got density and the density increases when the object is bigger and since the ship is so big it also got a really dense density. When the density of the object is bigger than the density of water it will sink.By adding air to the ship we can make the density smaller and will make the ship float.

People feel cold because heat will run out from your body therefore your body can't maintain your body temperature and caused over 3 million people to die each year, so clothes are created. Usually hoodies will limit the temperature from coming out of your body and helps you to keep the temperature in your body. However, if you wear too much clothes, your body will be over heated and feel ill.

The solution for this problem is to make and wear warm clothes to keep heat in your body from loosing heat and dying.

Why many people got sick and be sick?

2. solution:

3. Maybe the solution can be: To eat more food to be more warm, but don't eat cold food, then you will be more colder! M

2:Maybe science can make something that if you Operate something then it will be warm.

3:you can make a bag that Furry outside and waterproof inside.Then you can put warm water inside then it will be hot.

Q1. Why we feel cold.

Q2. You can wear puffer jackets or gloves. But some schools may have a rule for no other jacket than the school jackets. Since its winter you can wear it.

https://byjus.com/question-answer/why-does-a-ship-made-of-iron-and-steel-float-in-water-whereas-a-small/#

The problem is that people feel too cold in winter, which will cause frostbite, fever, Hypothermia, and even death.

2. SOLUTION

Threw science we can design special jackets to keep the heat from spreading and would not be as cold. Threw history we designed multiple inventions to keep warm inside and outside. For example:WWW

3. IMPLICATION

[2]people create some materials that can defend cold, some are used to make our jacket that wear during cold seasons.

[3]after researching, I found that wools, acrylic wools, polyester fleece and other materials that used in jackets can defend cold and keep the heat inside when we wear it in cold weather.

2.Identify and summarize the scientific principles that have used to solve the problem.

Our normal response to cold temperatures is to move blood away from the skin to keep the internal organs warm. In people with Raynaud's phenomenon, that natural response is extreme. The tiny blood vessels get severely narrowed, and blood flow to the skin drastically drops, most often in the fingers and toes.

why do we feel cold

2:solution

wear some warm cloth or go in. the house

3:implacation

so ,to feel warm ,we could wear warm clocth and stay inside

we need to go travel by boat ,but the metel is very hevei .

2:solution

The answer to why ships can float comes from the famous principle of Archimedes which says that the net upward force on an object immersed in water is equal to the weight of the water displaced by the object. If a large object like a ship is lowered slowly into water, it will displace more and more water until the weight of water displaced equals the weight of the ship, at which point it will stop dropping and “float”. If, of course, the ship is too heavy (say it was filled with too much steel or other heavy stuff) then the weight of water displaced will never equal the ship’s weight and it will never float (it will sink like a stone).

3: implication ?

4:citation

https://www.royalsociety.org.nz/150th-anniversary/ask-me-questions/why-can-ships-float/

The problem is that some ships don't float, and so people can't transport from one place to another, and so cargo and goods can not be transport.

2. SOLUTION

So now people don't use Materials that have very high mass, so they float.

3. Finding

The more mass there is the harder is will be to float.

4.

1. The problem is that we feel cold when we stay outside too long. that is the problem because if we feel cold, we might get sick.

2.There are some materials that help us not to feel cold. and scientists use those materials to solve and to make jumpers, socks and jackets. The jumpers, socks and jackets help us not to feel cold.

3. Some good materials are so expensive. So poor people can not buy the jumpers, socks and jackets. and good materials are hard to get.

2.A balloon filled up with gas would only go up in the air if it is filled up with a gas whose density is lower than air as the fluid with higher density always settles down.

The problem that science has addressed is that if the boat does not float on water, people could not travel to different countries using water transportation, because if a boat that is made out by metal is more denser than the density of the water, but the boat that is made out by wood is less denser of the density for water. For concluding, I do not suggest people travel on the sea, because it is dangerous and easy to get sink

Solution:

The scientific principle used to solve this problem by saying that this problem is mainly concept with density. Everything has density. Density is the amount of matter and mass inside an object. To solve the problem, we need to know that water also has density, so we need to make Sur that if we add an object on water, it could sink because of their density. So we need could a wood boat to travel on the ocean, because that boat is less denser for water rather that a boat that is made our from metal, the density is different so the percentage that they could float or sink is different.

Feeling cold is problem because it will make you uncomfortable if the temperature is not extremely low. If the temperature reduces you might shiver and have clumsy movements and poor judgment. If the temperature is extremely low it can lead to death because the body is unable keep warm.

How science solved this problem

Scienctists have developed materials that can help keep temperature in a person's body. Materials with good insulation [insulation in clothing is by trapping tiny pockets of warm air close to the skin. Air is a poor conductor of heat, and is therefore ideal as an insulating element. The air contained in an insulated clothing item will block heat from escaping from the body, and the more trapped air there is, the higher the insulating factor].include jackets and also things made out of wool. Also things like wetsuits that trap water instead of air. but the best jackets at protecting you from the cold are Parkas because they are designed to provide maximum warmth and protection from the elements. These winter jackets are typically longer and more insulated than other types, making them ideal for extreme cold weather conditions. and this jackets works by trapping body heat close to the skin to keep you warm

Explain the finding

The material traps and keeps warm air next to the body to maintain the body temperature. andusually have a flap that snaps over the zipper. This reduces cold entering through the teeth of the zipper and keeps your core warm – protecting your vital organs and arms simultaneously.
