First Day Chemistry Engineering Activity

I just finished my first week of school, like many teachers in the Midwest. I work hard to get my Honors Chemistry students in a lab setting as soon as possible. It is difficult to find a perfect lab to do on the first or second day of school. In my mind, the ideal first chemistry lab would require no prior chemistry knowledge, involve interesting chemistry, address an NGSS standard, be relatively safe, not require expensive glassware or lab tools, and reinforce positive class norms. I have found engineering labs fit the bill! I don't know if I have found the "perfect" lab, but I have found something close I want to share!

Scrub Daddy Science

The science behind the incredibly popular Scrub Daddy sponge is investigated. Part of the appeal of the Scrub Daddy sponge is that it changes from soft to hard depending upon temperature. This allows a single sponge to be transformed into a hard scrubber or soft sponge, depending upon the temperature of water into which it is placed.

Polymer Day: Outreach Experiments for High School Students: An ACS Authors' Choice article

The authors of the recent Journal of Chemical Education article, PolymerDay: Outreach Experiments for High School Students, offer a collection of interactive polymer activities designed to be part of an all-day outreach event for high school students. For teachers that might use the activities on separate occasions and/or as part of their curriculum, the authors recommend an accessible resource to support that work.

This is an article and is open access to all.

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.
