Right now, most school budgets are depleted for the 2015-2016 class year. My book, Chemistry on a Budget, contains inexpensive chemistry labs that could be useful. You can buy this lab book for $23 at amazon.com or lulu.com. Check it out!
There are two versions of each lab, one with a ten-question conclusion and one with directions for a full lab report. This way the teacher has the option! Each lab is two pages to allow for one two-sided handout.
It will take a week or so to get to you, so Order Now!

Methane [CH4] has been leaking at a storage facility in the Santa Susana Mountains in California -- this was first reported on October 23, 2015.
The following article contains video footage of the methane (CH4) gas leak.
One family has already filed a lawsuit – residents are reporting symptoms of dizziness, fatigue, coughing and irritation in the eyes and throat, and bleeding.
"A broken injection-well pipe about 500 ft (152.4m) below the surface is believed to be the culprit behind the leak, reports say. Pipes like this are used by utility companies to insert gas into the ground for storage until a later time when it can be withdrawn and sold for use. It is not known why the pipe ruptured."
“Gov. Jerry Brown declared an emergency last week for the prolonged blowout that requires the utility (Southern California Gas Co.) to cover the costs and instructs state regulators to protect ratepayers.
The well is one of 115 in the Santa Susana Mountains where Southern California Gas Co. [SoCalGas], a division of San Diego-based Sempra Energy, stores natural gas in a vacant oil field about a mile and a half underground. It is the largest natural gas storage facility west of the Mississippi River and can provide energy to all of Southern California for a month."
“It’s a combination of oil and gas companies failing to monitor and maintain aging infrastructure and a lack of oversight of the oil and gas industry. For too long, we have gone without federal and state standards that require sufficient leak and safety inspections for oil and gas facilities, and industry has shown it can’t be trusted to fix the problem on its own.
When leaks do occur, they may go unnoticed indefinitely, since methane is colorless and odorless." https://www.edf.org/climate/aliso-canyon-leak-sheds-light-national-problem
“To stop the leak, the utility company...is drilling down 8,000 feet and using a relief well to intersect the leaking pipe and plug it up. Crews are being very careful, drilling just 20 feet a day. Still, SoCalGas announced they expect to have the leak plugged by the end of February.”
“Methane itself poses no long-term health risks, but a severe natural gas leak can cause short-term symptoms, including dizziness, fatigue, nausea, headache and irregular breathing. Officials believe the ailments community members are experiencing are from an odorant added to natural gas to make it detectable.”
“ ‘Methane [CH4] is in a category of greenhouse gases known as short-lived climate pollutants,’ California's Air Resources Board [ARB] says on its website. "These types of gases remain in the atmosphere for a much shorter period of time than longer-lived climate pollutants, such as carbon dioxide (CO2); but when measured in terms of how they heat the atmosphere, their impacts can be tens, hundreds, or even thousands of times greater than that of carbon dioxide."
[As reported on January 20, 2116,] “[a]ir quality regulators agreed… to scrap a proposal to capture and burn off some of the methane spewing into the air from a subterranean pipeline rupture that has forced thousands of Los Angeles residents from their homes since October . … The stench of odorized methane fumes has sickened scores of people and led to efforts to temporarily relocate more than 6,000 households from the Porter Ranch community of northern Los Angeles at the edge of the leaking Aliso Canyon gas storage field.”
The following article summarizes this issue into 5 facts that may be useful for classroom discussion:
I have written about several ecological accidents/ concerns over the past few months. This was not to be alarmist, but to inspire discussion in your classes about the cost/benefit of maintaining infrastructure and the potential cost/benefit of cleanup of past toxic disposal.
I have stated before in the blog post “Current Event – Radioactive Waste from WWII” dated 10/30/2015, that you might want to coordinate with the corresponding Social Studies teacher(s) because these clean-up decisions are made by elected representatives within budgetary limits. Your students will be tax-paying, voting citizens very soon and will have a voice/choice with their representatives and town/cities where they live!
