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.
A 5-Star Customer Review of Chemistry on a Budget at amazon.com states:
“[S]traight forward, to the point, using household chemicals… this is the lab book for you.
I teach high school chemistry and this is exactly what I was looking for. Labs included simple household chemicals that could be easily found. Nice format, easy to follow along procedures, and touches on every topic of our chemistry curriculum.”

“Farm manure could be a viable source of renewable energy to help reduce greenhouse gas emissions that cause global warming.
Researchers at the University of Waterloo [in Canada] are developing technology to produce renewable natural gas from manure so it can be added to the existing energy supply system for heating homes and powering industries. That would eliminate particularly harmful gases released by naturally decomposing manure when it is spread on farm fields as fertilizer and partially replace fossil natural gas, a significant contributor to global warming.”
“In a paper published in January  in the International Journal of Energy Research, chemical engineer David Simakov and his team proposed a technology that can convert manure into natural gas with the potential to heat homes, power factories, and supplement diesel fuel. …
The benefits of renewable natural gas are twofold, according to Simakov. For one, it’s biogenic, meaning it’s from a biological rather than fossil source, making it more easily replenished. It also doesn’t add more net carbon-dioxide to the atmosphere when it’s burned for heating.
The researchers developed a computer model of a 2,000-cow dairy farm that converts manure into biogas by starving it of oxygen. This biogas can be used to power generators, using 30 to 40 percent of its energy potential. But by feeding the biogas hydrogen gas (which the researchers suggest could be generated via wind or solar power) and running it through a catalytic converter, Simakov and his team hope to convert it to natural gas, utilizing most of its energy potential and significantly decreasing the greenhouse gas emissions."
“Researchers want to take those benefits a significant step further by upgrading, or converting, biogas from manure into renewable natural gas. That would involve mixing it with hydrogen, then running it through a catalytic converter. A chemical reaction in the converter would produce methane from carbon dioxide in the biogas.
Known as methanation, the process would require electricity to produce hydrogen, but that power could be generated on-site by renewable wind or solar systems, or taken from the electrical grid at times of low demand. The net result would be renewable natural gas that yields almost all of manure's energy potential and also efficiently stores electricity, but has only a fraction of the greenhouse gas impact of manure used as fertilizer.
‘This is how we can make the transition from fossil-based energy to renewable energy using existing infrastructure, which is a tremendous advantage,’ said Simakov, who collaborates with fellow chemical engineering professor Michael Fowler.
The modelling study showed that a $5-million investment in a methanation system at the Ontario farm would, with government price subsidies for renewable natural gas, have about a five-year payback period.”
