Group 7(Ways to reduce methane, ozone and unburnt hydrocarbons in the environment) by Yee Jian, Yan Chong, Ya Ning, Ming Chung

Here's our video :

And here's our question ---
1) If cars were not invented, will there be less methane in the environment? Explain why?
2) What are the effects of  absence of ozone on the Earth?

And finally here's the Bonus Question!!

1) Explain the relationship between fast food chain stores and dinosaurs with regarding to this chapter.

Group 2 Oxides of nitrogen

Here is our youtube video!

And our open-ended question is:

What are the common sources of nitrogen oxides and

What are the negative effects of nitrogen oxides to the environment?

By Rongxing, Yukai, Matthew and Xiaozhi

Group 5 Ozone and CFCs

This is the link to our video:

Question:
1.Discuss why is Ozone important in the Stratosphere layer.
2.Explain why people living in Australia have a higher chance of getting skin cancer.

By: Htoo(8),Qianhong(17),Jieling(18),Wang Yu(23)

Group 8 open ended question (':

1) Give one word equation on how carbon dioxide is added to the atmosphere.
2) Explain why the increase in concentration of carbon dioxide is a major environmental concern.
3) Explain why methane is a greenhouse gas of greater impact than carbon dioxide.

Group 6: Reduce Sulfur Dioxide, Oxides of Nitrogen and Carbon Monoxide Emission in the Environment

Here's the link to our video http://www.youtube.com/watch?v=5v3FixwnE-0  :)

Our question to you!
What are more ways of reducing these gases in our daily lives?

Group 1: Sources and Effect of Sulfur Dioxide

What is Sulfur dioxide?

• A colourless, pungent gas
• Harmful pollutant (top 6 air pollutants)
• chemical formula of SO2

Sources of sulfur dioxide

•  Natural

1. Release from oceans
2. forest fires
3. biological decay
4. Volcanic activity 

• Industrial 

1. Emissions from industrial facilities 
2. fossil fuel combustion
3. Generating electricity supply

Effects of sulfur dioxide

• reacts with water vapour or other chemicals in the atmosphere to form sulfur based particles which reflect the sun's rays and cools the earth for periods of time (not necessarily a positive effect)
• sulfur dioxide forms haze which reduces visibility
• irritates eyes and cause breathing difficulties as it irritates lungs too
• Forms into acid rain (rain with pH value of 4 or less)

1. dissolves in rainwater to form sulfurous acid                                                                          (SO2 (g) +H2O (l)---> H2SO3 (aq) )
2. sulfurous acid is oxidised in air to form sulfuric acid                                                                   (2 H2SO3 (aq)+ O2 (g) ---> 2 H2SO4 (aq) )
3. Acid rain leaches important nutrients from soil and destroys plants
4. reduce pH value of natural water bodies and kill aquatic life 
5. reacts with metals and carbonates, thus corroding and destroying monuments, statues, buildings and bridges

Open ended question: 

Now that you know about the effects of sulfur dioxide on the environment, how is sulfur dioxide used in our daily lives and how does it affect us be it positively or negatively?

Group 4: Sources and Effects of Unburnt Hydrocarbons and Methane to the Environment

Hi Guys! 

This is the link to our awesome YouTube video hope you guys enjoy it! 

Group 4 AWESOME Video (CLICK HERE) (Watch in 1080p HD for the best quality)

Here is our open-ended question to all of you :)

Unburnt Hydrocarbons and Methane are both produced in our daily lives. 

We all know about the bad effects of Methane and Unburnt Hydrocarbons, but did you know that there are actually good effects too! 

Discuss on the benefits that Methane and Unburnt Hydrocarbons have to our Environment, it can be social, economical or even anything!

Thank You for your time and have a great day ahead!

~Chemistry is AWESOME!~ 

Welcome to the Sec 3 Chemistry Project 2014!

Hi Sec 3s!

Welcome to your class blog for the 

Chemistry Project on Air and The Environment!

All necessary detailed instructions are already given on your Class Google Site. 

*****GENERAL INSTRUCTIONS*****

This blog serves as a central canvas for all groups in the class to display the products of  your hard work! EVERY GROUP SHOULD ONLY HAVE ONE POST containing the following:

1. Group Name and Group Members + Register Numbers
2. Link to the group's YouTube video [using the "Link" function in the blog post composition.]
3. Open-Ended Question from your group for the other groups to respond and discuss

*****THE YOUTUBE VIDEO*****

To get you started, you can click on the following link to view one example of a YouTube video made by your seniors from the Sec 3 cohort of 2013. 

Link: Example YouTube Video from Sec 3 Cohort of 2013

Instructions on how to upload a YouTube video are on your Google Site. 

*****THE OPEN-ENDED QUESTION AND DISCUSSION*****

Each group should also post at least 1 response on every group's  open-ended question using the "Comment" function found below each post. 

For every "Comment" your group posts, remember to sign off with your Group and Members' names! 

Some expectations we have of you when commenting on one another's posts:

• Exercise sensitivity and respect in your discussion - understand that everyone is entitled to his/her own opinions and he/she should be free to express his/her views
• Do not use profanities / vulgar / uncouth language - it is both uncivilised and very rude to do so
• Post constructive, well-thought comments and discussion - do not answer for the sake of it, or parrot what others have said, or simply paraphrase the question
• Observe cyber-wellness - Do not post unauthorized, sensitive or illegal content. Alert the teachers immediately if you see signs of deliberate cyber bullying. 
• Credit all sources that you use to substantiate your discussion - Do not plagiarize blindly. Respect the intellectual property of other people who have posted on the internet. 

Feel free to discuss away!
