\nMicrobeads and Engineering Design in Chemistry: No Small Educational

Abstract: A multipart laboratory activity introducing microbeads was
\ncreated to meet engineering and engineering design practices consistent
\nwith new Next Generation Science Standards (NGSS). Microbeads are a
\ncurrent topic of concern as they have been found to cause adverse
\nimpacts in both marine and freshwater systems resulting in multiple
\nstates proposing or adopting legislation to ban their manufacture or
\nsale. The activity allows for student inquiry, discovery, and
\nengineering design using inexpensive, readily available, and safe
\nchemicals. In addition, the products tested (toothpastes,
\nfacial-cleansers, and\/or hand-cleansers) will be familiar items to the
\nstudents, stressing the ubiquitous nature of chemistry. The activity
\nfostered confidence in the students through designing and testing
\nprocedures, introduced them to a topic that most knew nothing about, and
\ndrew praise for achieving the learning goals while investigating a
\nrelevant real-world problem.<\/p>\n
