The solar system

Our solar system consists of an average star we call the sun, with eight planets moving around the sun which they are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. It includes also satellites of the planets which are the moons, Comets, asteroids and meteoroids. I will just focus on the sun and the planets.

The sun is the richest source of electromagnetic energy in the solar system, and mostly we got it from heat and light. The mass of the sun is very huge with 1.98*10³⁰ Kg approximately, with 99.85% of all masses in the entire solar system.

nto two part; inner planets and outer planets. The inner planets are the first four planets starting from the nearest planet from the sun which is Mercury, and it is the smallest planets in the solar system. Venus, earth and mars comes after it. The outer planets are the last four planets starting from Jupiter which is the biggest planets, and Saturn, Uranus and Neptune comes after it.

From 1930 until 2006, Pluto was classified as a planet. But after that, the IAU decided to exclude Pluto from the planets and added as a member of a dwarf planet with other 4 dwarf planets because in some points it crosses the orbit of the neighbor planet.

report for presentation

Presenting students:   1-Mohamed Adnan     H00099357

Venue: class W113

Starting time: 4:00

End time: 4:16

The topic was about industrial revolution. Mohamed introduced the topic, but it wasn’t that good because he didn’t mention all the main points that they were going to talk about; he just gave us a background of the industrial revolution as an introduction. Mohamed had good eye contact with the audience, as Ahmed did. Mohamed was standing to the right of the screen and at the same time Ahmed was standing to the left of the screen. Both of them weren’t using note cards, and this is an advantage for them as they could remember all the points that they were talking about. Both of them were speaking in a clear and a loud voice with nice smiles and good confidence.  Ahmed had many hand gestures while he was talking, so he could put across the information to the audience clearly. Mohamed always started the new points and then Ahmed completed the idea.

About the power point, the slides background was simple and clear. They didn’t put any notes on the slides, only a title and a picture for every slide, which were seven slides. So they didn’t depend a lot on the power point, and I think that it is a bad thing on a presentation.

Finally, I think the presentation was very good in general, because of the new information we learnt. One of the important things is that both of the students were sharing all the points, which meant they were working together in all the main points. After the presentation they answered all the questions that they were asked.

Reflection of our meeting

As I was the chairman, I started the meeting by introducing the minutes taker who was Ali Hadi and the participant who was Abdulla Marzouq. I set the time of the meeting and selected the points that we were going to talk about. We discussed about the global warming, reasons, consequences and solutions for it. We agreed on all the points except one point in the solutions. In the meeting, I tried to find a workable solution, not a solution that can’t be done. Every person in the meeting put his ideas in detail and the others commented on them, saying if he agreed or disagreed. At the end, we listed the main points that we had come up with. I think our meeting was organized so that every person participated with his ideas equally.

Meeting of Global warming

Date of meeting:         21/06/11

Time of meeting:        2:55 PM

Venue:                          Abu Dhabi Men’s College in W104

Group members:

·         Chairman: Mohamed Ahmed

·         Minute taker:   Ali Hadi.

·         Participant: Abdulla Marzouq

Agenda:

1- The reasons for the global warming.

2- The consequences of the global warming.

3- Making people aware of the global warming

4- Using another fuels instead of petrol and diesel.

5- Using public transport.

The Chairman Mohammed called the meeting to order at 3:00 PM

1-      The reasons for the global warming:

Ali said there are two main reasons of the global warming which are humans’ activities and natural reasons. Mohammed and Abdulla agreed with Ali, but the chairman said we will not discuss about the natural reasons because we cannot find a solution for them. Abdulla said one of the human activities is that humans use cars, airplanes, and trains for transportation. And this transportation causes the CO2 in the air which causes the global warming.  

2- The consequences of the global warming

·            The chairman Mohammed said let us turn our attention to the consequences. Ali said “the high temperature leads to the spread of pests and diseases that the insects transmit such as malaria.” Abdulla pointed out that the high temperature causes melting of the massive glaciers that raises the sea level, so it’s very dangerous for people who are living on the islands and near the coast. The chairman Mohammed agreed with the two consequences and he said let us move to the most important part with is the solution.

3-    Making the people aware of the global warming

·          Abdulla asked if we can make aware all the people around the world about the danger of the climate change. Ali pointed out that it’s difficult to raise the awareness of all the people because some regions don’t have enough means of communications. The chairman said if we make aware as many people as we can, that would be enough to reduce the dangers of the global warming. Ali said the best way to make aware many people is by T.V or Internet because it’s common between the people. Abdulla and Mohamed agreed with this solution.

4-       Using other fuels instead of petrol and diesel.

·         Abdulla suggested using other sources of power that have not bad effects in the environment such as solar power, wind energy and water energy. Mohammed and Ali didn’t agree with Abdulla because it’s not very viable because it’s not practical and the oil is very cheap.

5-       Using public transport.

·         The chairman said let’s see another solution that’s workable. Ali suggested using public transportation to reduce the use of the cars. For example, metro, public buses and electric trains.

The chairman Mohamed said that these are good solutions to reduce the pollution which is an effect of global warming, and he said we should list the output of the meeting.

·                  In conclusion we thought that:

1-      Global warming is a very dangerous phenomenon in the world.

2-      Making the people aware is a good idea to make them deal with this phenomenon.

3-      Using other fuels is not a viable solution.

4-      We liked the idea of using public transportation.
