Getting Chemistry In The Community Into Your Classroom or Club
I ran a Chem 101 course for three years at a community college serving primarily first-generation students. The materials exist, the ACS publishes them freely, but getting people to actually use them is the harder part. Here is how it works in practice. The American Chemical Society created Chemistry In The Community as a semester-long survey course for students who are not planning to major in chemistry or any related science. It replaced the old general chemistry sequence that most non-science majors suffered through — three hours of weekly lectures on stoichiometry and equilibrium calculations they would never use again. The book covers six main units: structure and properties of matter, chemical reactions, solutions, rates and equilibrium, acids and bases, and an introduction to organic and biochemistry. Each chapter is built around real-world applications, like the chemistry of soaps and detergents, water treatment, or the chemistry of food. The textbook itself is free to download from the ACS website. You do not need to buy it. There is also a separate instructor resource site with lab manuals, demo scripts, and slideshow decks. I found the slides useful but heavily annotated by me — they skip over the mathematical derivation of pH calculations entirely, which frustrated students who had taken AP chemistry and expected rigor. The workaround was to assign the OpenStax General Chemistry chapters on acids and bases as supplementary reading when those students needed more depth.
Setting Up the Course
The official Chem 101 version of this curriculum runs for 15 weeks with three lecture hours and one lab hour per week. You can compress it into a seven-week intensive or stretch it across a full semester with additional projects. I used the seven-week model for summer bridge programs and it worked fine if you cut the lab component down to demos rather than hands-on experiments. The full 15-week schedule gives you time for the culminating community project, which is where the "In The Community" part actually lives — students design and execute a chemistry-related public education activity, like a water quality testing workshop for a local neighborhood association or a demonstration series at a library. The lab manual is available separately. It includes 24 experiments ranging from simple qualitative analysis to titrations using household vinegar. One thing the manual does not cover well is safety documentation for student-written labs. When my students designed their own community project, I had them fill out a risk assessment form before any experiment happened. The ACS materials do not include a standardized template for that, so I adapted one from our institutional IRB process. It added about two hours of administrative work per group but prevented a real incident where a student wanted to test lead levels in tap water using a method that required acid digestion without a fume hood.
Downloading the Materials
The ACS Chemistry In The Community page hosts the textbook PDF, the instructor guide, and the lab manual. Search for "ACS Chemistry In The Community Chem 101 resources" and you will land on the right section. The instructor site requires free registration but no institutional email. Student-facing materials can be shared directly as PDFs without any login barrier. I exported the textbook chapters as individual PDFs and uploaded them to our learning management system so students could access them on phones without downloading the entire 600-page file. Students coming in with zero science background sometimes choke on the quantitative sections. The curriculum assumes high school algebra proficiency but does not explicitly teach it. I built a two-page reference sheet covering scientific notation, unit conversions, and basic algebra rearrangement and distributed it in week one. It reduced the number of students dropping the course due to math anxiety by roughly half based on my enrollment retention comparison across semesters. Another issue is that the labs assume access to a basic chemistry lab with balances, Bunsen burners, and glassware. If you are running this in a classroom without a lab, you can substitute every experiment with a demonstration or a virtual lab simulation. The PhET simulations from the University of Colorado cover most of the key concepts, particularly the acid-base and equilibrium units. I stopped trying to source vinegar and baking soda for the household chemistry labs and just showed the reactions on camera instead. The learning outcomes stayed the same.
Get the Full Details
The biggest gap in the published materials is assessment. There are chapter quizzes available but they are multiple choice and do not align perfectly with the application-focused approach of the textbook. I wrote my own short-answer questions after each unit that required students to explain a phenomenon in their own words rather than select a letter. It took more grading time — maybe twenty minutes per section across a class of thirty — but it actually measured whether they understood the material.
Running the Community Project
The final project is the signature element of this curriculum and the part that most instructors skip because it requires external coordination. The assignment asks students to identify a chemistry issue in their local community, research the science behind it, and create an educational product for a non-specialist audience. Past projects I have seen include a brochure on reducing household chemical waste, a presentation to a retirement community about medication interactions, and a workshop for a local scout troop on water filtration. The key constraint is that the target audience must actually be community members, not fellow students. When I allowed student audiences, the work degraded into textbook regurgitation rather than genuine public communication. I required a preliminary meeting with the host organization or community group before any project work began. This meant students had to articulate their topic and methodology to a real person outside the classroom. Several groups struggled with this in week ten because they had picked overly broad topics like "pollution" without narrowing to a specific chemical or process. I had them fill out a one-page project charter that specified the exact audience, the chemical concept being taught, and the format of the final product. It forced scope discipline that saved weeks of revision later. The rubric the ACS provides is generic. I adjusted it to weight the accuracy of the chemistry more heavily than the polish of the presentation. A poorly designed poster with correct information earned a higher grade than a professionally designed one with a fundamental error. That decision upset some students who had graphic design skills but weak chemistry fundamentals, but it kept the focus where it belonged.
When This Curriculum Does Not Fit
If you are teaching students who plan to take Organic Chemistry II or Biochemistry as prerequisites for a nursing or pre-med track, Chem 101 is too thin. It deliberately avoids the depth required for those sequences. Those students should take regular General Chemistry instead. Similarly, if your institution requires a lab component with wet experiments and you cannot secure lab space or safety equipment, the course loses its experiential anchor and becomes a lecture-heavy survey that does not justify the credit hours. The curriculum also assumes you have at least one semester to implement it properly. Trying to cram it into a four-week workshop produces superficial coverage of every topic without the depth needed for the community project to work meaningfully. I tried that once and the final presentations were underdeveloped because the students had never internalized the underlying chemistry well enough to teach it to others.
Summary of What You Need
The textbook and lab manual are free from the ACS. Registration on their instructor portal takes about five minutes. You will need to create your own assessment questions and safety documentation because those are not included in the published materials. The community project component requires external partnerships that may take three to four weeks to establish, so plan accordingly. If you can manage the administrative overhead, the curriculum produces students who actually understand chemistry at a level they can explain to non-scientists, which is a rarer outcome than most introductory courses achieve.
