Space Exploration Essay

So the question that we are asking ourselves are how much is space exploration really worth to human society? Does it outweigh the costs? What are the benefits and what are our limitations? At the end, we will find out. I think that we could benefit a lot from space exploration because for example, if anything happens to our earth, if we searched the space we might find a new place to go to. Also, we might find some new species of life form. Another thing that we could find, is materials such as the rocks on the moon… etc. But even though I think these would all be great ideas, there are some costs too. It might happen for example that the engine is dead, or something happens to the rocket, like on the video we watched with the teacher going to space, the whole crew could die. I think that sending people to the moon and other planets is a great idea, because like I said, we could find new species, and we would become even smarter than we are now. But I think that only doing Earth-based research isn’t a good idea because like that we can only learn about our planet, and we wouldn’t know anything else about the rest of the universe. I don’t think that we shouldn’t learn about earth at all though, because if we do, we wouldn’t know to predict what can happen to it. So I think that it is important that we do both.

If I had to chose 5 top things my country would work on, the first thing would be medical studies, because with medical studies, we would find out about new medicine, and it would make our life a bit longer. The second thing would be education, because without education, nobody would have the knowledge to do all the tasks, especially medical studies! The third thing would science studies, because like that we could make new technology, and sell them to other countries for money so we could spend it on other things. The fourth thing would be transportation, such as airports, marines… etc. Like this tourist would come to our country, and we would get a lot of money on that. But like this we would import and export materials. And the fifth thing that I think would be important is space exploration, because with that, we could find new things, and then sell them to other countries. Also we would get better knowledge of space.

In conclusion, I think that space exploration is very important to human society, because we would find out more about the universe. It does outweigh the costs because with space exploration, like I said before, we can find so many things we can now only imagine! And there are much more benefits then limitations!

Reasons for the seasons Lab Report

1.     If it is winter in the Northern Hemisphere, the southern hemisphere will be getting the direct light, since the earth is tilted, but if it is summer in the Northern hemisphere, then there will be the direct light!

2.     During the summer they get direct light and during winter they don’t get direct light.

3.     You would get more heat and it would be hotter

4.     It will always be hottest near the equator since wherever the heat is going towards, it will always hit the equator, and it is the coolest at the poles, since there is where the least amount of heat goes, which then makes it cooler than in other places on the planet

5.     At summer, the tooth pick will be longest, since that is when the heat is headed towards you (depending where in the world you are) and in the winter it will be shortest because at that point is when not a lot of heat is headed toward you, and makes it cold (and the tooth pick short).

6.     They are related because they are the places that the sun rays hit the earth

7.     Since the earth is tilted on its axis (23.5^o), if the sun’s rays are headed to the southern part of the hemisphere, that is where it will be summer, since it’s the part of the earth that is getting direct heat from the sun. But, since in the northern part of the hemisphere there is no direct heat, there will be winter because there is less heat. And also the other way around. When the direct heat is going towards the Northern hemisphere, then there will be summer and in the southern hemisphere there is no direct heat so it will be winter.

 

 

Solar Storm

On Thursday March 8^th, the biggest solar storm hit us in the last 5 years! On Friday morning, the solar storm changed its direction, and hit earth massively as it travelled 4.5 million mph towards the southern side of earth. Luckily for us, this only made some little disrupts, and didn’t harm any of the satellites, electric grids, and GPS systems. The only thing that it did do was cause some auroras to happen in places like Michigan, Seattle, Alaska, New Zealand, Minnesota and Australia. On the grid, from G1 to G5 with G5 being the most powerful, this solar storm was rated G3. The largest solar storm to hit earth was in 1859. The Northern Lights where so powerful that they could be seen all the way up where Cuba is! And the Southern Lights were also so powerful that they were able to be seen all the way down in Santiago, which is in Chile. In some parts of the USA it was so bright that you could read your newspaper without turning on the lights because of how bright the aurora was! Luckily, back then there were no GPS’s and satellites to be broken, but some of the USA equipment was burned.

Zebras Bug Repellent

Zebra’s striped skin is what their bug repellent is. Scientists first thought that their stripes where to get away from predators, because in a herd, it’s hard to recognize what one zebra is! The study was led by a group of Swedish Scientists. The first clue they found out, is that dark horses got bit more than light colored or white horses. Since we know that the zebras are born black, and get their white stripes as they grow, so the made a theory that that is why zebras aren’t attracted to flies. They tested it by taking a black horse, and took white paint, and painted him so he would have white stripes like zebras. Their result was that not many flies went to bite him, but they did go for the rest of the horses that were not black and white. Even though the theory makes 100% sense, it has never been tested on a real zebra. If it is like this, then another question the scientist will have is why did zebras develop the stripes and horses didn’t, even though they are close relatives. Scientists think because in Africa, where the zebras are from, are a lot of horseflies, and there aren’t much horses there, the zebras had to get the stripes, and horses didn’t!

Urban Farming

We have found out that by the time year 2050 comes, there will be an additional 9.1 million people! It will be very hard to feed everyone in the world. 70% of all people will be living in the city! The idea of urban farming has been going on for a while, but never really happened, until now! In Sweden, a huge skyscraper was built for the urban farming, but also for scientist from all around the earth to come and share their ideas and improve urban farming. In this skyscraper, the temperature is made by a machine that helps them, and the city’s air, because it absorbs the carbon dioxide from nearby buildings and uses that to create the temperature, to weather it needs to be cold or warm. If everything goes as planned, they will begin farming in 12-16 months! If it turns out a success, then they will start making these buildings all around the world so that there would be urban farming in other countries, and not just in Sweden! If this all works, it would get rid of the food crisis in the next 40 years!
