Tracy N. Vassiliev; Douglas J. Gardner; David J. Neivandt – Science Activities: Projects and Curriculum Ideas in STEM Classrooms, 2024
This STEM research project asks middle school or high school students to work towards creating ecologically friendly packaging. Packaging that can be composted instead of thrown away and collected in landfills and oceans like plastics. This inquiry uses nanocellulose and focuses on water permeability. The fibers of nanocellulose can be dried to…

Isokawa, Naho; Fueda, Kazuki; Miyagawa, Korin; Kanno, Kenichi – Journal of Chemical Education, 2015
Poly(vinyl alcohol) (PVA) precipitates in many kinds of aqueous salt solutions. While sodium sulfate, a coagulant for PVA fiber, precipitates PVA to yield a white rigid gel, coagulation of PVA with aluminum sulfate, a coagulant for water treatment, yields a slime-like viscoelastic fluid. One type of homemade slime is prepared under basic…

Hudson, Reuben; Glaisher, Samuel; Bishop, Alexandra; Katz, Jeffrey L. – Journal of Chemical Education, 2015
A multiple day activity for students to create large-scale plastic objects from the biopolymer chitin (major component of lobster, crab, and shrimp shells) is described. The plastic objects created are durable and made from benign materials, making them suitable for students to take home to play with. Since the student-created plastic objects are…

So, Wing-Mui Winnie; Cheng, Nga-Yee Irene; Chow, Cheuk-Fai; Zhan, Ying – Education 3-13, 2016
This study aims to examine the impacts of the inquiry learning strategies employed in a "Plastic Education Project" on primary students' knowledge, beliefs and intended behaviour in Hong Kong. Student questionnaires and a test on plastic types were adopted for data collection. Results reveal that the inquiry learning strategies…

Howder, Collin R.; Groen, Kyle D.; Kuntzleman, Thomas S. – Journal of Chemical Education, 2010
A hands-on activity and demonstration, both applicable to the 2010 National Chemistry Week theme of Behind the Scenes with Chemistry, are presented. In the activity, students compare and contrast the properties of heat conductors and heat insulators. During the demonstration, students learn that water absorbed by a superabsorbent polymer can…

Caspar, A.; And Others – Journal of Chemical Education, 1986
Proposes a two-stage experimental approach that combines preparative chemistry and polymer characterization. Describes the simple organic synthesis of a plasticizer, the dioctylphthalate, and its direct use in the preparation of a styrene/divinylbenzene network copolymer. Discusses how to evaluate the physical properties of the resulting plastic.…

Britton, L. N.; And Others – Journal of Chemical Education, 1988
Considers the applicability of the simple emersion/weight-gain method for predicting diffusion coefficients, solubilities, and permeation rates of chemicals in polymers that do not undergo physical and chemical deterioration. Presents the theoretical background, procedures and typical results related to this activity. (CW)
