Microplastics, Liquid Nitrogen, and Iodine: Polystyrene vs. Starch Foam Packing Peanuts
Dean Campbell | Wed, 07/28/2021 - 13:03
The differing electrostatic and solubility properties of starch and polystyrene foam packing peanuts are used in various demonstrations to describe aspects of microplastics and their interactions with the environment. Their differing responses to exposure to liquid nitrogen and iodine solutions are also described.

Stacks of LEGO bricks can be used to illustrate the composition and pressures of various planetary atmospheres. Guides for the construction and use of these atmosphere sticks are provided.
Surveying Litter as a Citizen Science Chemistry Activity
Dean Campbell | Sun, 05/30/2021 - 10:25
During the last few semesters, a small survey has been deployed at Bradley University where students were to describe and classify items of litter that they found. The purposes of the surveys were to get students thinking about some of the chemical implications of solid waste and give the students some experience with a citizen science project. The most recent iteration of the survey, and some of its results, are described.

Learn a simple way to relate the heat equation (Q = mc∆T ) to climate change.
Why Green Chemistry? Or Better Yet, Why Not Green Chemistry?
Erika Fatura | Mon, 08/05/2019 - 22:50
My top 5 reasons for using Green Chemistry in my classroom along with a few examples of replacement labs that follow Green Chemistry principles.
Book Suggestion: The Alchemy of Air
lowell Thomson | Fri, 01/05/2018 - 03:08
One of my goals for 2017 was to read more chemistry non-fiction. I accomplished that with three and a half books read. That doesn't seem like much, but given how busy I've been lately it was quite an accomplishment! I offer a brief review of my most recent book here, "The Alchemy of Air" by Thomas Hager.
Chemical Connections to Climate Change
Tom Kuntzleman | Wed, 01/25/2017 - 11:11
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.
Solution to Chemical Mystery #6: The Case of the Collapsing Can
Tom Kuntzleman | Sun, 06/05/2016 - 17:12
Solution to Chemical Mystery #6 is presented. Also, concepts related to the chemical can crush demo are briefly discussed.
Pondering Packing Peanut Polymers
In this Activity, students compare polystrene and cornstarch packing materials ("peanuts"). Both are made of polymers, but because of their composition, they behave very differently in various solvents. Students extrapolate how these differences in behavior relate to environmental effects, such as filling landfills with non-biodegradable materials.
