Biosorption is a method that can be used for the removal of pollutants from wastewater, especially those that are not easily biodegradable. This experiment uses citrus fruit peels as part of a iodometric titration to conduct a wastewater treatment binding copper.
I have been interested in the adsorption properties of shells and other common materials. I decided to test the adsorption properties of almond shells towards methylene blue and I am sharing how it went here.
A greener procedure that you might consider to replace the traditional "formula of a hydrate lab" that has typically used copper II sulfate.
A fantastic resource to help you learn more about how to teach climate change and global warming is described.
In “A Global Warming Primer”, Jeffrey Bennett provides a template for conversation about the most pressing global environmental issue of our time. The author also recommends a link to the ACS Climate Science Toolkit that offers many useful resources for learning about and teaching the concepts related to climate science.
Have you considered having your students make solar cells? If your AP kids can understand batteries, solar cells are a logical next step. I usually do independent projects after AP along with final presentations, but I stumbled upon this activity the other day and my mind exploded in excitement and thought I would share. In the future, I would definitely do this with my students!
Beyond Benign, a national nonprofit, established in 2007 to equip educators, scientists, and citizens with the tools to teach and practice green chemistry to achieve a sustainable society, just announced a strategic partnership with Flinn Scientific.
It is becoming increasingly important for citizens to understand various concepts related to climate change and global warming. This post describes several chemical concepts that are pertinent to these issues, in the hopes that teachers of science and chemistry can introduce the topic of climate change into their classrooms and everyday discussions.
What draws you in to read an article you see in a magazine or journal? Past experiences? Current interests? In the case of the November 2015 issue of the Journal of Chemical Education, it was Darth Vader.
In this Activity, students use multi-colored breakfast cereal and liquid to model the concepts of leachate and leaching from municipal solid waste disposed of in a landfill. Students create a modern landfill model with the same material. This environmental chemistry Activity can be used to complement a celebration of Earth Day.
