Physical Science Research paper?
I missed a lab and am now able to write a 5 page (minimum) research paper to make it up. It’s for a non-major physical science class. He said it can be anything that relates to physical science but gave us some options of: history of physical science, environmental issues, physical science in industry, or biographical sketches of a famous scientist. Since I’m not too familiar with the subject, I’m having a hard time finding a topic to write about.
If anyone has any ideas, it’d be greatly appreciated!
The Expert answers:
Search on how environmental elements like water, air … Can tolerate and absorb a fairly large amount of pollution.
Paul asks…
How far out of the spotlight has climate change been pushed?
And more importantly, what are the future prospects for carbon emission reduction policies and other man made global warming reduction measures?
According to Newsweek, the outlook is rather grim for what over the last couple of years has been the number one environmental agenda issue, the hot potato so to speak. Here are some interesting snippets:
“…controlling the global climate turned out to be a lot more complicated than the advocates of fierce and fast CO2 cuts would have us believe.”
“…economists disagree widely on whether the cost of the current set of policies, such as carbon caps and green-fuel subsidies, is justified by the avoided damage from warmer temperatures.”
“In many ways, green projects have become just another flavor of grubby interest politics. Biofuels have become a new label for old-style agricultural subsidies that funnel some $20 billion annually to landowners with little effect on emissions…”
“A new climate realism would more carefully weigh the costs and benefits of emissions controls, and look at other options beyond the current set of targets. The new debate will be more pragmatic and include a broader mix of policies.”
What are you thoughts on the source article? http://www.newsweek.com/2010/07/12/a-green-retreat.html
Dana – Let me guess, 97% of certified and chartered economists support cap and trade. The 3% who don’t are either unqualified, retired, haven’t published in years or are economy-deniers like Bjorn Lomborg.
I patiently await the publication of the supporting study/poll. However, it will be fascinating to see if it’s published in a peer-reviewed economy journal or a climate journal.
virtualguy – I believe it was written by Wilt Chamberlain.

If Copenhagen didn’t deflate the expectations of the AGWers nothing will.
The very governments they hope to initiate change, walked away washing their hands.
Like rats deserting a sinking ships, they will hope that the world will forget about this conundrum called climate change.
Daniel asks…
do you know ways on how to apply “conservation of mass” in our daily lives?
our prof is making us do this report about our experiment on conservation of mass. do you know any activities/ways/applications wherein the concept of conserving mass is used in our day to day activities..(like a social issue, environmental issue..etc.) ex. experiment on icecream making: featuring “selecta”/”magnolia”… <— something like that… tnx!
The Expert answers:
Water may be frozen, melted or turned to steam with zero change in mass. Ordinary chemical reactions result in no change in mass (only nuclear reactions change mass). Burning gasoline (in a car) combines oxygen with hydrocarbons to form CO, CO2, and H20 vapor (ignoring NOx’s) and the weight (mass) of the gasoline and oxygen exactly equals the weight of the products of combustion. Eating and metabolizing ice cream does not result in a net change in mass (although a person’s weight may change because he does not exercise enough to produce sufficient CO2 and metabolic water).
Joseph asks…
What can I do to protect the environment?
Most people are concern of environmental changes and issues like pollution or global warming. What can we do? We are millions, if all of us can do something, even if is the slightiest one, we could help.
There is always something we can do. Half of electricity produced in USA, is the result of burning thousands of tons of coal per generating plant. Every second tons of Carbon Dioxide is expelled to the atmosphere. We can try not to use electricity unnecessarilly.
I remember most police cars in many towns in USA, are running idle their motors in the police park lots. “Just in case” they said. USA is the biggest consumer of fossil fuel. Many scientist have said there will be a point of no return in 50 years or so. Oceans will be uncapable to absorbe that much Carbon Dioxide. Algae, coral and plancton will die. Global tempereature will rise. It could be the next global extintion, all caused by humnans. But humans can think and take awareness fo this. We cannot wait for this to happen
The Expert answers:
I wouldn’t worry. The “pollution” cars supposedly kill the o-zone layer with have been coming from volcanoes and other things of natural for thousands of years. The ozone layer has dealth with it just fine up until now.
William asks…
Can I take a Honda Element from California to Canada when I move?
I am moving from California to Canada and wanting to buy a Honda element before the move. Can I take it with me over the boarder and register it in canada? My dad seems to think that there will be issues with the smog and environmental laws, since he thinks that they differ from the US to canada. Any ideas where I can get information on this? Thanks in Advance!!
The Expert answers:
Honda Elements are built in North America…Marysville, OH to be precise. Check the Canadian owners threads on the forum at http://www.elementownersclub.com If you don’t find what you’re looking for post this question there. The EOC is a very active and helpful site with tons of information from enthusiastic owners.
