- Explaining more about having 3 sex chromosomes, because most 7th graders didn't understand it
I also just noticed that I can change the color of the post on any web browser except for Google Chrome!
Teréz's Reflection post
I think the benefit of a class blog is that you can just look and see what you mist when you are sick and you can check if there is homework if you don1t know or forgot. Another good thing is that people who are not in the school or class can check out what the class was doing what I thing is very interesting. A bad thing is that some people who never check the blog miss their turn.

Iva's Reflection Post
I feel that by now I can write a blog post much easier. I do not have as many problems with technology because I learned that I have to write in everything right away, without copying from a Word document. It is not frustrating me as much. I need to improve in putting in more pictures and writing everything we covered in class and be more thorough.
The benefits of having a class blog is that you can always check it if you are sick, and the non-benefits are that Blogger can give some problems, and that comments get deleted very easily. My comments got deleted quite a few times and that was very irritating.

Thursday 24, 2011
On Thursday’s science class the first thing we did was look at the homework that was due. Ms. D made sure that we understand what we needed to do by going over it.
Tuesday- Apod #3
- Phases and Eclipses lab
Thursday- Reflection post
- Send someone outside of the AISZ community an email with the link to our blog. Make sure to CC Ms.D in it.
All the homework that is due is also on moodle. This picture above shows Cernan Flanked on the moon
After that, Ms. D checked our homework that was due on Thursday, which was:
-How many Apollo missions were there to the moon?
- There were 6 Apollo missions to the moon, but 17 in total.
-How many men officially walked on the moon?
- 12 men have officially walked on the moon.
- Ms.D also wanted us to remember these two people: Neil Armstrong and Edwin Aldrin(Buzz)
- Neil Armstrong: one small step for man, one giant leap for man kind
Another thing that we talked about in class was the ISS and the space shuttle program. The ISS( International Space Station) is a working and living environment. We also talked about that the space shuttle program ends this year.
We ended the class with the Phases and Eclipses Lab. The teams finished drawing the pictures and some even went to the computer lab to finish the summery.
We had had to include 8 drawing of the moon, one of a lunar eclipse and one of a solar eclipse in the lab.(new moon, waxing crescent moon, first quarter moon, waxing gibbous moon, full moon, waning gibbous, last quarter/ third quarter moon, waning crescent, lunar eclipse, solar eclipse)

22/3/11 Science Class
First, we talked about the upcoming homework that is due. This is it:
Sunday, March 20, 2011
Thursday 17th, 2011 - Science Class
Thursday in science class we learned many things;
Ms. D. started off by updating us about the news in Japan; and to know more about it, click here.
Next, Ms. D. showed us an example of a well-done APOD. To write and do well an APOD, we should concentrate more on the subjects hyperlinked, not on the actual picture we choose. Here you can find the Moodle page in which the APOD example is saved.
And this is the website of the Astronomy Picture Of the Day.
Then, we received an article (which is in Moodle) about the satellite MESSENGER, that has finally made it to Mercury.
The satellite was launched in 2007, but because of the speed of Mercury, it took very long for it to actually reach the planet.
At a first glance, Mercury seems very close to Earth and very easy to reach, but it actually travels at an average speed of 106,000 mph (miles per hour), and is very close to the Sun. Also, a curious fact about Mercury is that one side of the planet is extremely hot and the other side is extremely cold. So, the satellite had to have features that could stand both temperatures to get close to it. Scientists from NASA, in order to make MESSENGER reach Mercury, had to speed the satellite up to 65,000 mph and make sure that it could stand extreme temperatures. You can find a video about future movement of the MESSENGER to study Mercury here.
Later on, we looked at some pictures about world time zones and latitude and longitude.
World time zones:
In this picture you can see all the world time zones. They are labelled in different colors, and chosen by the actual country. Every color corresponds to a number listed underneath the world map with the same color. Some countries have time zones labelled as -3 1/2, or +9 1/2, just because the country chose so.
And latitude and longitude:
This picture, then, shows the latitude and the longitude of Earth. The latitude goes from North to South, while the longitude goes from West to East.
After looking at these pictures, we corrected our homework.
The homework was to label summer solstice*, winter solstice*, autumnal equinox* and vernal equinox* in the map we drew in class and to answer these questions:
1) How many different divisions of NASA are there and where are they located?
2) What does ESA stand for, where is it located and what countries are involved in it?
Here are the answers.
1)
- NASA Headquarters: Washington D.C.
- Marshall- Huntsville, AL
- Ames- Moffett Field, CA
- Goddard- Greenbelt, MD
- Johnson- Houston, TX
- Kennedy, FL
- JPL (Jet Propulsion Lab)- Pasaden, CA
- Langley- Hampton, VA
- Glenn- Cleveland, OH
- White Sands, Cruces, NM
- Stennis- MS
- Dryden- Edwards, CA
- Wallops- VA
- IV & V Facility- Fairmont, WV
- Plum Brook- Sandusky, OH
2) ESA - European Space Agency
Headquarters in Paris; Austronauts Centers - Cologne, Germany; Astronomy Center - Madrid, Spain; Space Operations - Germany; Center for Earth Observations - Rome, Italy; Space Research and Tech Center - Netherlands.
The countries involved are: Germany, Belgium, Denmark, Spain, Finland, France, Italy, Ireland, Israel, Luxemburg, Norway, Netherlands, Portugal, Czech Republic, Romania, England, Sweden, Switzerland.
Finally, on Moodle, is posted all of the homework for this week and next week.
Some useful links would be:
The next scribe is Iva.
---------------------------------------------------------------------------------------------------------
*Summer Solstice: occurs when the axial tilt of Earth is most inclined towards the sun, on June 22nd/23rd. (Longer day, shorter night)
*Winter Solstice: occurs when the axial tilt is farthest away from the sun, on December 27th. (Longer night, shorter day)
*Autumnal Equinox: occurs when the axial tilt is neither towards the sun nor far from it. Happens on September 23rd. (Equal night and day, 12h each)
*Vernal Equinox: occurs when the axial tilt is neither towards the sun nor far from it. It happens on March 21st. (Equal night and day, 12h each)
Friday, March 18th
Our homework was to find out:
How many divisions of NASA there are, what they are, and where they are located. Then, we also had to find what ESA stands for, where it is located, and which countries are involved in it.
The answers to our homework were:
There are 15 divisions on NASA (including NASA headquarters). They are:
(Division- Location)
NASA headquarters- Washington DC
Marshall- AL
Ames- CA
Goddard- MD
Johnson- TX
Kennedy- FL
JPL- CA
Langley- VA
Glenn- OH
Dryden- CA
White Sands- NM
Stennis- MS
Wallaps- VA
IV & V Facility- WV
Plum Brook- OH
Second, we went over our homework for the next three weeks.
1. We had a APOD due Tuesday at 8:00. (We can send Ms. D a rough draft on Monday)
2. For Thursday, we have a Ted Talk due, on anybody presenting astronomy related topics.
3. And due Friday, we have our last blog comment due.
For the other two weeks, you can click here and you will be able to see what our homework is.
After that, we talked more about the "super moon" (below),
and then we watched a video about how the MESSENGER entered Mercury's orbit, and how scientists are making it get into Mercury's orbit.
If you click here you will be able to see a few photos, and captions of the MESSENGER around Mercury.
We also watched a video about the moon, were it spoke about apogees and perigees.
An apogee is when the moon is farther away from the Earth, and a perigee is when the moon is closer to the Earth.
We drew a diagram which explained all that. Since I cannot draw the diagram, here is a picture that explains what they are in a simple way.
And that is all that we covered in class on Friday.

Science Class on March 15
In today’s class we did two main things. We talked about Japan and the Earth.
First Miss D. checked our moon homework.
Than she explained to us what happened in Japan in the last few days.
The picture on the right side shows some of the houses that collapsed because of the earthquake and the tsunami in Japan.
The other problem in Japan at the moment are the nuclear reactors which explode. Click here to see how nuclear reactor #3 explodes. It is pretty scary.
After we finished talking about Japan we went on to our actual topic, the Earth. The symbol of the Earth is a circle with a cross in the middle as you can see it on the left side. (If you can't see it click on it and it will become bigger). The four parts stand for the four elements.
Rotation: The Earth spinning around its own exes.
The Earths rotation takes 23 hours and 59 minutes. This happens counterclockwise.
Revolution: The Earth traveling around the Sun.
This process takes 365 1/4 days =365 days and 5 hours.
You can prove that a year is 365 1/4 days long, because of the Lap year every 4 years when 4 times 1/4 day makes one. This is when there is a February 29.
The distance on Earth is measured with longitudes and latitudes.
The prime meridian is at 0 degrees longitude.
The equator is at 0 degrees latitude.
The other two very important latitude lines are tropic of cancer, tropic of Capricorn. Tropic of Cancer is located at 23.5° N and the Tropic of Capricorn is located at 23.5° S.
This webpage gives you very interesting scientific facts about the Earth.
Here are some interesting facts about the Earth.
We didn't have homework, but you can still check out Moodle.
I hope you liked it.

Friday, March 11: The Start Of Astronomy
Astronomy Picture of the Day: March 11
Today during class Ms. D. told us that most people did really badly on the little “What you know about astronomy” quiz, we have to start at the very beginning. Then Ms. D. gave us our debate grades back, and then we went back to astronomy. First Ms. D. gave us our homework.
Homework list:
1. 1.Moon- remember to put the direction of the moon and a picture or description about how the moon looks.
2. 2.The APOD (Astronomy Picture of the Day) –remember that you need to explain the science of the picture that you chose. You can choose pictures from August- December of 2010 and January-March of 2011. After you have chosen a picture and explained the science, you need to tell Ms. D. why you chose that picture (min 3 sentences). After you have done that, email Ms. D. at dani.dipietro@aisz.hr. This is due every Tuesday at 8 am
Link to APOD: http://apod.nasa.gov/apod/archivepix.html
Link to MOODLE for further info about science: http://zagreb.ceesa.net/
After we talked about the homework, we watched a video called Power of 10. Power of 10 talks about the size of the universe. The video showed us how big and small the universe is.
Did you know: If we traveled 10,000 light years away from earth, we will not be able to see the Milky Way galaxy; but if we travelled 100,000 light years away from earth, we will be able to the Milky Way galaxy.

Class of Thursday, March 10th
Wednesday, March 9, 2011
Class of 3/8/11
This was the day which the debates happened. The two topics were; Embryonic stem cells, and genetically engineered children, which are commonly referred to as designer babies. Designer babies are quite literally babies that have been designed. So far all that can be selected for a child to have is; skin color,hair color,eye color, and gender. Embryonic stem cells are cells derived form embryos that can be used to create a cell culture of any type of cell.
Designer babies overview
Embryonic stem cells overview
There are two videos that briefly explain what the two topics are.
At the beginning of class we had fifteen minutes to make final preparations. Most groups printed out their text, organized what was going to happen or made a few final changes to their work.
To be fair Ms. D decided that a game of rock paper scissors would decide who would go first. One person from each of the topics was selected and the winning group would go second. The embryonic stem cell side lost the game and went first. Since it was an informal debate their was no order and when the starting speakers on each side had long introductions Ms. D told them to just convey the points with no accompanying science.
The con team took the approach that it is unethical and costs to much money to research and adult stem cells should be used instead. Adult stem cells are tissue samples taken from an adult who remains alive throughout the testing and then converted to use on other patients.
Example on how Adult stem cells to cure heart injuries
The pro team explained that it had the opportunity to save many lives with just one cell, and that it could be turned into anything and that the embryo most of the time would be aborted anyway so we should use the resource.
At the end there was a class vote. Most of the class thought that the pro had won, one person thought the con had won, and a few including Ms. D didn't know who won the debate.
We then immediately moved on to the designer baby debate.
The con team talked about the theoretical risks of creating babies like this such as eliminating helpful DNA by accident, Upset parents not getting what they paid for with the only 60% chance with the best luck, the wanting to create a pure society, intellectually difference causing gap between designer and natural babies much like the gap between rich and poor, the expense, and genetic war weapons (referred to in the debate as babies of mass destruction).
The pro team disputed the cons ideas by saying it was only theoretical ideas about what could happen. They also burst out laughing at the idea of babies of mass destruction and cast it off as irrelevant. The main point that was brought up was that diseases and mutations would no longer exist because they could be fixed before birth.
The end vote concluded that the pro team won this debate.
With this genetics is officially over and 8th grade is moving into astronomy.
To start this our homework is to record the position of the moon for seven days.

If I forgot a point in the debate please tell me in your comment.

Scribe Post: Feb.28th-Mar.4th
Science classes during the week of Feb.28th-March 6th
March 1st:
First our class has discussed what we were going to need for the finished Inherited Traits Lab of AISZ, which we have already started on Science Day. We should take care of the graph, and make it well organized. Don't forget to have a title for the graph, and don't forget the conclusion paragraph. You must have 5 UVs and 3 CVs.
The Extra-Credit Karyotype Activity is going to be due Thursday March 3rd. You wil have to have all the matching chromosome on an A4 peace of paper and you will have to tell Ms.D if the person is a male/female and if he/she has a mutation or not.
After that we started discussing our new project: The Ethics and Genetics Fish Bowl Discussion. We are supposed to have a team in which we will eighter support Pro or Con-arguments of the themes: Embryonic Stem Cells/Genetics testing on babies.
1.) The embryonic stem cells theme is about taking cells from embryos which could help to heal cancer or other yet not healed sicknesses. But ethnic groups are having problems with that because it might kill embryos which they call life. On the right you can see how embryonic stem cells are produced.
2.) The Genetics testing on babies is mainly about: if parents should be allowed to change the phenotypes (looking) of their unborn child. Some say yes, some no.
Also don't forget to make a bibliography of all your sources you have used (in APA-format).The discussion is going to be 20 minutes per theme and you will discuss on Tuesday 8th March. We took cards which then split us up into 4 groups. Then Ms. D allowed us to go to the computer-lab to get some more general knowledge and first facts for the rest of the class. The picture on the left is suppose to show if people should play around with a baby DNA.
March 3rd:
On this day our teams again went the whole block into the computer-lab to collect more data. And take out the best arguments of the articles we read.
March 5th:
We only had 45 minutes that day and were again allowed to stay in the computer-lab the whole block. People were summarizing their work and finishing up their bibliographies and were ready to discuss on Tuesday March 8th.
You might want to use that Link to Moodle for the directions of the discussion: HERE
