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.”

“Sri Lanka’s government announced the implementation of a ban on the production and sale of plastic bags effective Friday, September 1,  after the collapse of the island's largest dump led to a rubbish disposal crisis. The ban will reportedly not be enforced until January 2018, and also covers the use or manufacture of expanded polystyrene. Those in violation of the ban will face two-years imprisonment and/or a fine of 10,000 Sri Lankan rupees (USD 65).
The government stated it would replace plastic bags with reusable cloth bags, however there has been widespread opposition to the ban. Sri Lanka's polythene manufacturers claim that around 345,000 employees would lose their jobs.”
BTW, polythene is also known as polyethylene.
“Rotting garbage piled up in many parts of the capital, [Sri Jayawardenepura Kotte], after the giant rubbish tip collapsed in April , crushing dozens of homes and killing 32 people.
Many blamed the haphazard use of plastic, which was also cited in flash flooding in the capital after storm water drains became clogged.”
“Polythene and Styrofoam is used by local shops to wrap lunch. Polythene shopping bags [are] also widely used in supermarkets and shops.
Shopping bags will be replaced with reusable cloth bags under the new law, the Central Environmental Authority said. “

In response, President Maithripala Sirisena banned the sale of plastic bags, cups and plates, as well as the burning of refuse containing plastic.”
“Local residents have complained that piles of garbage have been left uncollected in the capital with the government vowing that it would clean up Colombo and its outskirts soon.
Sri Lanka is also facing its worst ever dengue epidemic with over 225 patients killed and over 80,000 infected.”
What is dengue?
“With more than one-third of the world’s population living in areas at risk for infection, dengue virus is a leading cause of illness and death in the tropics and subtropics. As many as 400 million people are infected yearly. Dengue is caused by any one of four related viruses transmitted by mosquitoes. There are not yet any vaccines to prevent infection with dengue virus and the most effective protective measures are those that avoid mosquito bites. When infected, early recognition and prompt supportive treatment can substantially lower the risk of medical complications and death.”
“Sri Lankan soldiers dug through rubbish with their bare hands Saturday to pull out victims after a huge garbage mountain collapsed on their homes, killing at least 15 people.
Four children were among the dead following Friday’s incident at Kolonnawa on the northeastern edge of the capital, Colombo national hospital spokeswoman Pushpa Soysa said.
The 300-foot (91-metre) high dump came crashing down on neighbouring homes…as the country marked the traditional new year.
Local residents have complained that piles of garbage have been left uncollected in the capital with the government vowing that it would clean up Colombo and its outskirts soon.”
“The short term measures also include the ban on the manufacture, import or sale of containers, plates, cups, spoons made of polystyrene, the ban on the sale of processed or cooked meals packed in polythene containers and the promotion of paper, cloth or reed bags or biologically degradable plastics for customers when purchasing items in stores, prohibition of burning polythene and plastic in open places introduction and promotion of biologically degradable polythene and plastics.
Tax concessions would be provided to import machinery for the manufacture of biologically degradable plastic and a cess tax of 15% on the import of plastic raw material and goods.
In the long term the use of recycled plastic products would be banned.”
