SSH - Germany
... First time posting .
Anyhow after seeing the amount of people studying Germany for the prelims , my first few posts will be about that chapter. Being such a huge topic , this will be split into 3 main parts. Today's post will be about the rise of Nazism in Germany. (Each post shall be written as if it was an SEQ btw)
Rise Of Nazism In Germany
5 Main Points
- Nazi Propaganda
- Great Depression
- Weakness of the Government
- Fear of Communism
- Hitler's Personal Qualities
1st Point - Nazi Propaganda
One of the reason why Nazism became prominent was due to spread of Nazi Propaganda in that period of time. Goebbels , who controlled the propaganda often used clever methods to spread the Nazi Message. An example of this can be seen when Goebbels used the media (posters, radio, television) and even rallies where he played patriotic songs which advocated National Socialism. Furthermore, he used propaganda to put other parties in a bad light, and at the same time elevating his party status in the country. This resulted in the party becoming prominent as it convinced a sizable amount of Germans to support the party. Thus making Nazi Propaganda an important reason of why the party rose to power.
2nd Point - Great Depression
Another important reason of why the party rose to power was due to the effects of the Great Depression. When the Great Depression occurred many factories were closed down, and this caused not only a shortage of consumer goods but also a huge shortage of jobs. Needless to say, a period of economic crisis soon occurred in the country. Many of the unemployed felt that the polices of the Nazis not only gave them a way out of their hardship, but also a way to make the country stronger. Therefore, the great depression is an important reason, as it caused many people from all walks of life who were affected by the crisis to look and support the Nazi party. Thus an important reason as to why Nazism rose to power.
3rd Point - Weakness of the government
Also another reason why the party came to power was due to flaws of the government. The government was often hindered in it's policy making and ruling of the country due to the system of proportional representation. In this system, the members of the parliament would often be split in the Percentage which the party received in the election. This often resulted in constant bickering within the government itself, and thus the government was often unable or too slow to solve the problems of the countries. An example of this can be seen during the Great Depression where the government was unable to implement polices to solve the problem of huge unemployment among the people. This resulted in the Germans losing faith in the system of democracy, and caused them to turn to the Nazi Party which was seen as the complete opposite of the government; strong and united.
4th point - Fear of Communism
Another reason as to why Nazism became prominent was also due to the exploitation of communism. During this period of time, the party often spread propaganda concerning the communist party. An example of this was how the party often said that communism would take away the wealthy possessions. This resulted in many of the people (rich) to fear communism. Thus the rich began to support the party. Consequently, many of wealthy donated money to the party allowing the Nazis to hold more rallies and often gain new supporters for their cause. Thus the fear of communism gave rise to the Nazi as it allowed them to gain even more supporters and also gave them more funds to spread their message faster among the people.
5th Point - Hitler's Personal Qualities
The final possible reason why the Nazi party was able to gain so much power was also due to Hitler's Personal qualities. Hitler among many other things was a brilliant political speaker. He often used to his advantage during rallies to captivate the audience. An example of what he did was to promise them that he would be able to restore Germany to it's former glory. Furthermore he promised to lessen the economic problems of the people. He even went to the extent of using clever techniques to make the Population support him and the party. Thus making it an important reason of why he rose to power as it allowed the party to gain a huge following which supported the party whole heartily.
These are main points of why the Nazi party rose to power. Several points are of course interlinked but can be easily be separated to ensure you have sufficient points for the essay. Also there may be several points i left out when i was doing this...
Hope this helps for your revision.

Chemistry SPA Skill 3
The following are some of the things I took note of during Mr Alex Lee's Revision with us on the 1st of July.
-----------------------------
3.1 Planning an Investigation
1. Aim
2. Approach
3. Variables: Varying & Constant
(Mr Lee's advice: do a draft)
-----------------------------
3.2 Planning & Procedure
4. Apparatus & Chemicals
5. Procedure
6. Results
7. Conclusion
-----------------------------
1. Aim
- think of what is the "big picture"
- usually, it can be copied from the worksheet title
2. Approach
- what are you measuring?
- what is the chemical reaction?
- what are the key variables?
"To measure/record the volume of gas collected in a fixed amount of time, when a fixed mass of CaCo3 is allowed to mix with hydrochloric acid of concentrations o.8M (A1), 1.0M (A2) and 1.2 (A3)."
- Start sentence with "measure" or "record"
3. Variables
- List ONE varying and SEVERAL controlled variables
note: be specific (don't use 'amount')
- when using time, mentione time "for what?" (for example, time taken for x reaction to finish)
- when using temperature, use "initial temperature"
tips on choosing a quantity to measure
Speed of Reaction: Measure time take for....
- a solid to completely disappear (easiest)
- a precipitate to form (for slow reactions)
- a fixed volume of gas to be collected
4. Apparatus & Chemicals
- You may specify SPECIFIC ITEMS
- for example, "three micro test tubes, each containing o.30 grams of magnesium powder"
- example 2: "three 2cm magnesium strips, eaqually cut"
this saves you the trouble of making it another step in the procedure =)
5. Procedure
- Don't forget preparation of material
Do NOT write in your procedure
"Identify a key source of error"
"Record your results in a suitable format"
6. Results
- Provide a table to show results
- Fill in values for the independent variable, but NOT results
(Don't forget UNITS)
- Mr Lee: DON'T NEED GRAPH
7. Conclusion
- How your results will provide and answer to your aim
- Use "if" because you do not know the results!
--------------------------------
Mr Lee's Suggested thought process
Read -> Construct Aim -> Visualise Experimental Set Up -> State Variables -> Construct Approach -> Construct Procedure
Voila!
---------------------------------
NOTE:
I did this out of "the kindness of my heart" (sound familiar?)
Please do not use this as an excuse to not pay attention to class and take down your own notes. Each of us hears things differently and tend to take down only things that have significance to ourselves. This means that I may have missed out some points Mr Lee may have mentioned (even my attention span wavers after a while) and you may have jotted down reminders to yourself that are important to yourself but of no significance to me. So, make the best you can out of this, but don't start slacking too much in class =) Good luck for Chemistry SPA Skill 3!

Common Mistakes in Chemistry Part One
Finally, the reason why I started this Blog. Henceforth I will be posting snippets of useful information from the tiny little notebook I carry around that is packed with information. Remember when Mr. Glenn Wong used a lesson to talk about common mistakes made in Chemistry? I copied almost everything down even though none of the mistakes were mine. The same goes with many other subjects, and from time to time I will post information I feel you guys will find useful. Use it well, and get your A's =)
-----------------------------------------------
Chemistry
- "Unsaturated" refers to "An Organic molecule with C=C bonds"
Note: Beware of using the term double C-C bonds because this could mean just mean a C-C bond here and another C-C bond there. The above mentioned definition is the safest.
- SPELL OUT chemicals unless asked for formulas
- When asked for Partial Structures in Organic Chemistry, don't forget to add the brackets and the 'n' symbol.
- There will be NO WRITING OF STATE SYMBOLS BELOW FORMULAS. Instead, write them beside the chemicals otherwise they will be disregarded (according to Mr Wong this is the latest change from MOE or someone higher up so don't complain)
- Ionic and Half Equations REQUIRE state symbols
- The term "precipitate" only refers to reactions between two MIXTURES. Whereas "residue" is used in filtration.
- Mole Calculations require 3 Significant Figures. HOWEVER, during your working, you may come across big values. If they have to be used later, keep them up to about 3 Decimal Places to be safe.
- Final answers during calculations involving Enthalpy Change should be kept exactly. One way to check the answer is that if you know the reaction is Endothermic/Exothermic, you will know the answer should be positive or negative respectively. COMBUSTION is EXOTHERMIC.
That's all for now. If you liked this post, don't bug me when I'm copying stuff down in class, and I'll happily share my notes.

Photos for the Blog Title Picture
See that nice photo of a mountain at the top of the page?
Wouldn't it be great if all of us were at the foot of the mountain?
I think it would. So send me some decent shots of yourself, preferably above the waist WITH CLOTHES ON, and I'll slowly add you guys into the picture, and when it's finished I'll put it up =)

Regarding Names & Authors
In response to the request on the Cbox for all of us to use our real names, YES, please use your real names as well as making sure that if your name is shared by another, include your surname.
On another note, I have sent an email to Jon Poh, to invite him as another Blog author to help post on History and SS. Once I have Joel Khoo's email, the same invitation will be sent. This post is also a call to those of you interested in helping post tips and other things. I already have several positions that I would be glad if some of you could help out with, such as an Activities Planner who can use this Blog to plan class activities, whether they be for leisure or for school-related purposes. Another person could help regularly update the Announcement Board too. I am also ready to give the Cbox account name and password to anyone who is willing to help monitor it to prevent potential spam.
Anyone interested should let me know.

27-28 May SPA Key Sources of Error
NOTE: The key sources of error mentioned below are speculations. Also, do remember that in Physics SPA we are allowed to write as many answers as possible and they will give us marks for one correct answer. For Chemistry SPA, we are allowed ONLY ONE answer. Always remember to write what the errors lead to. It is advisable to rephrase the answers mentioned below to fit the context of the question in the actual exam.
Physics: (topic is Light)
-Involving mirrors
There is glass in between the area where the light ray strikes at the mirror and the silvered surface (where the light ray is reflected), leading to inaccurate angles of reflection recorded.
The mirror is light and is easily shifted by accident, leading to inaccurate drawing of lines for the light rays.
-Involving pins
The pin holes are too big for a pencil to pass through accurately, leading to inaccurate drawing of lines for the light rays.
When pins are required to be placed at the edge of the glass block or mirror, the pins cannot be placed exactly at the edge of the block, leading to inaccurate drawing of lines for the light rays.
- Involving lenses
The exact point where a clear image is formed cannot be defined exactly (for reasons similar to that of comparing colours to the colour comparison chart in Chemistry), leading to...
Chemistry: (topic is Metals)
This topic is somewhat difficult due to the broad scope of possible experiments. I will try my best to cover as many possibilities as possible
- Involving reaction of metals with time as a variable
The stopwatch cannot be started at the exact time when the reaction begins due to human reaction time (remember those experiments involving the small test tubes?), leading to inaccurate timings recorded.
- Involving reactions of metals with heat as a variable
There is heat loss to the environment, leading to inaccurate readings of temperature change in the solution.
It will be great if you guys could inform me of any other possible answers that I have missed out, and I will edit this post accordingly. Good luck, and feel free to ask questions.
