For the 2018-19 school year, buy a copy of the lab book Chemistry on a Budget. It’s a great resource for your class!
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.”

“In October 2017, Drew Wynne collapsed inside a walk-in refrigerator at his coffee business in North Charleston, S.C. By the time his business partner found him crumpled on the floor, Wynne was dead. He had suffocated on a chemical called methylene chloride.
The 31-year-old's death is one of dozens blamed on popular paint removers sold under the brand names Goof-Off, Strypeeze, Klean Strip and Jasco among others.
In recent months, some retailers have said they will stop selling products that contain methylene chloride, also known as DCM, and a second chemical, N-Methyl-2-pyrrolidone, or NMP. …
The EPA began a risk assessment of methylene chloride in 2014. In January 2017 the agency proposed banning the use of methylene chloride and NMP in paint removers. In the proposed rule, the agency wrote that the chemicals posed "unreasonable risks" to consumers.
Since 1980, more than 50 deaths had been attributed to methylene chloride, according to an investigation by the Center for Public Integrity and Slate.
But the proposed rule has yet to become an actual ban. Methylene chloride manufacturers opposed it, and in public comments in the spring of 2017, the Halogenated Solvents Industry Alliance urged the agency to delay it, saying the regulation would have a ‘devastating impact on consumers and small businesses.’ A spokesperson for the industry group, Faye Graul, declined to comment for this story, and the major U.S. manufacturer of methylene chloride, W.M. Barr, did not respond to interview requests.
Today, it's still legal to sell products containing both chemicals. Health and safety experts caution consumers to avoid using them — especially indoors.”

“Halogenated solvents are solvents which contain a halogen such as chlorine, bromine or iodine.
HSIA focuses on the most popular halogenated solvents, the chlorinated solvents:
- Dichloromethane, or Methylene Chloride
“Exposure to methylene chloride, also known as dichloromethane, has been associated with a higher risk of cancer and neurological and liver problems in workers, according to a 2014 assessment conducted by EPA. It also found that consumers who use methylene chloride paint strippers face short-term risks of neurological effects.
Environmental and consumer advocacy groups are encouraged by EPA’s decision to finalize the proposed ban on methylene chloride in paint-removing products. ‘It is vitally important that EPA move quickly to implement a ban,’ says Sarah Vogel, vice president for health at the Environmental Defense Fund. EPA should follow procedures to guarantee a permanent ban and ensure that ‘these products are promptly removed from store shelves,’ she adds.”
“Why ban methylene chloride? Methylene chloride is highly neurotoxic, and acutely lethal. There have been over 50 deaths from acute exposure over the last thirty-five years – though many more likely have gone unreported. Many of these deaths have been associated with the use of methylene chloride-based paint stripping products in confined spaces. Recent CBS news segments have covered the tragic stories of Kevin Hartley and Drew Wynne who both were killed in separate incidents in 2017 while using methylene chloride-based paint strippers.
The EPA fact sheet on the ban cites not only lethal risks from acute exposures to methylene chloride from use in paint and coating removal products, but also a host of other acute and chronic health impacts, like harm to the central nervous system, liver toxicity, and cancer.
Despite the serious risks to human health and the availability of safer alternatives, products containing the chemical remain on shelves across the country.”
“The Environmental Defense Fund says 50 people have died from exposure to methylene chloride in such products since the 1980s. The chemical has also been implicated in three deaths, including Drew’s, since the proposed ban. The Tennessee man who died was reportedly working as a professional, refinishing bathtubs in Nashville. We reached out to the EPA to find out when the agency will take action, but we did not hear back.
We also reached out the manufacturer of the product Drew had been using at the time of his death. But after repeated attempts, the company did not respond. Its product does include a clear warning about its potential dangers on the back label. Its website says it’s the largest manufacturer of solvent, removers, fuels, cleaning and prep products. …
We did talk to a Pennsylvania family who sued the manufacturer of ‘Goof Off’ nearly 20 years ago. Judy and Wayne Steiner say their son Brian was 30 years-old when he was using a similar product by the same company to refinish a car. They say he had a heart attack and survived. But they say he continued to have heart problems until he died from another heart attack five years later. The Steiners say the company settled the lawsuit and although it did not admit to any wrong doing, they thought the issue had been resolved.”
Another report of a death due to methylene choride is reported below:
“Joshua [Atkins] was a snowboarder, a climber, and most of all, he loved freestyle BMX biking. …
But in February , Joshua Atkins was visiting his mother in South Connellsville, Fayette County, and died suddenly. He had been removing paint from his BMX bike with a chemical paint stripper. Lauren Atkins found him after she came home from working a late shift. …
A toxicology report revealed her only son died from methylene chloride inhalation. The chemical is an ingredient in paint strippers sold at hardware stores, and is also used commercially. According to data compiled by the group Safer Chemicals, Healthy Families, methylene chloride has been linked to at least 64 deaths since 1980.
Beth Kemler with Safer Chemicals, Healthy Families says things changed a couple of weeks ago when a delegation of people whose family members had died from methylene chloride inhalation met with EPA administrator Scott Pruitt in Washington.
‘They told Joshua’s story and also the stories of their loved ones who they had lost,’ Kemler says. ‘And just two days later, EPA actually issued a press release saying saying that they were going to move forward on finalizing the proposal.’
But Kemler and others aren’t waiting for the EPA. They’re pushing for retailers like Home Depot and Lowe’s to stop carrying products that contain methylene chloride now. In an emailed statement, Lowe’s says the chemical ‘has historically been the most effective product option for removing paints and varnishes efficiently,’ and that the company does provide several alternatives that don’t contain methylene chloride. Critics of an outright ban say better labeling could help keep people safe.
But Maureen Swanson with the Learning Disabilities Association of America, says beyond these documented fatalities, there are other risks to using products that contain methylene chloride, and another common chemical called NMP.
'Pregnant women exposed to these toxic paint stripping chemicals have babies who are at higher risk for learning and developmental problems including A.D.H.D like behaviors,' she says. 'EPA states that children in the home when methylene chloride is used can suffer permanent learning impairments.’
Swanson says there is no reason for stores to delay removing products that contain these chemicals from their shelves.
In June , Lauren Atkins will travel to the Lowe’s shareholder meeting in Charlotte, North Carolina to share the story of her son’s death, and ask the company’s CEO to ban methylene chloride products.”
“Safer Chemicals Healthy Families fights for strong chemical policy, works with retailers to phase out hazardous chemicals and transform the marketplace, and educates the public about ways to protect our families from toxic chemicals.
Our coalition of 450 organizations and businesses is united by our common concern about toxic chemicals in our homes, places of work, and products we use every day.”
