Abstract: A multipart laboratory activity introducing microbeads was
created to meet engineering and engineering design practices consistent
with new Next Generation Science Standards (NGSS). Microbeads are a
current topic of concern as they have been found to cause adverse
impacts in both marine and freshwater systems resulting in multiple
states proposing or adopting legislation to ban their manufacture or
sale. The activity allows for student inquiry, discovery, and
engineering design using inexpensive, readily available, and safe
chemicals. In addition, the products tested (toothpastes,
facial-cleansers, and/or hand-cleansers) will be familiar items to the
students, stressing the ubiquitous nature of chemistry. The activity
fostered confidence in the students through designing and testing
procedures, introduced them to a topic that most knew nothing about, and
drew praise for achieving the learning goals while investigating a
relevant real-world problem.
