Engineering silver nanoparticles for use in water filters has shown promising results in keeping water free of disinfection byproducts that arise after chlorination. In this activity, the students do individual research to learn about nanotechnology and silver nanoparticles, and how silver nanoparticles can be used in water treatment. Students choose a plant of their choice (from home, school, or from the teacher) to use as an agent to reduce silver nitrate into silver… Read more

Students are challenged to use computer-aided design (CAD) software to create "complete" 3D-printed molecule models that take into consideration bond angles and lone-pair positioning. To begin, they explore two interactive digital simulations: "build a molecule" and "molecule shapes." This aids them in comparing and contrasting existing molecular modeling approaches—ball-and-stick, space-filling, and valence shell electron pair repulsion (VSEPR)—so as to… Read more

This activity focuses on the use of graphene in organic fibers, and their applications in organic electronics, e-textiles and wearable technologies. Students learn about the properties of graphene—unique form of carbon—and how graphene-based fibers are fabricated, how to measure resistance, how to calculate resistivity, and how a material changes its electrical properties. Students also learn about the importance of defining design parameters, which is an… Read more

Educational Goal To understand: How polylactic acid (PLA) plastic is an example of green chemistry technology particularly pollution prevention and designing safer chemicals Student Objectives Students will: Learn about renewable "corn" plastic is made from polylactic acid Recycle the polylactic acid cup into a new product: a cleaning solution Conduct a saponification reaction Analyze PLA against the 12 principles of green chemistry (Optional) Verify the contents of their… Read more
