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.
Beyond Benign develops and supports teachers to advance sustainable science education. Learn how these teachers are practicing Green Chemistry in the classroom, mentoring colleagues, and growing professional learning communities.

A greener procedure that you might consider to replace the traditional "formula of a hydrate lab" that has typically used copper II sulfate.
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.
You can perform an orange to black chemistry demonstration using materials commonly found in stores. The reaction appears to be similar to the Old Nassau reaction, but uses greener reagents. This is a great demonstration to do around Halloween time.
