We believe that students should have opportunities-early and often-to learn about science and math activities in fun and recreational ways. As a result, we try to provide many science enrichment activities to the surrounding community. In doing so, we hope to inspire young students to become future scientists and mathematicians. Here we describe some annual science outreach events that we have hosted, share a few demonstrations and activities we have tried at these events, and discuss how we plan to connect our outreach in 2011 to the themes of the International Year of Chemistry.

“…3 Cooling the ball reduces the motion of its polymer chains and converts them from a viscoelastic state to a glassy state. 4 This conversion makes the polymers brittle rather than flexible, 5 which prevents them from rebounding after impact. These examples provide interactive illustrations for students of how temperature impacts objects.…”

“…Similar to happy/sad ball toys that illustrate elastic versus inelastic collisions, the extent of rebound of a single ball after it hits the floor can be impacted by changing its temperature . Cooling the ball reduces the motion of its polymer chains and converts them from a viscoelastic state to a glassy state . This conversion makes the polymers brittle rather than flexible, which prevents them from rebounding after impact.…”

A collection of four activities for science outreach events was developed to teach middle school students about the temperature dependence of scientific phenomena. Procedures are described for four interactive demonstrations on phase changes, fluorescence, viscosity effects on diffusion, and conductivity. Each hands-on activity helps students visualize the scientific concept under investigation while they use the scientific method to evaluate the effects of temperature on experiment outcomes. Activities were designed to be completed relatively quickly and at low cost, which facilitates their incorporation into science outreach events.

“…The barrier to entry to studying polymer chemistry has been lowered for young students by utilizing a childhood toy, elastomer bouncy balls . This platform has previously been used to study the dynamics of bouncing. , Additional experiments have used rubber bouncy balls to probe the effect of temperature on elasticity and bounce height. ,, Others have used silicones in classrooms to study paint wettability in art, and to develop ink stamps . The protocol by Mengelt describes the process of fabricating silicone balls using ping-pong ball molds.…”

Design of a Guided Inquiry Classroom Activity to Investigate Effects of Chemistry on Physical Properties of Elastomers

Typical organization of science and mathematics K12 education divides subjects into discrete courses. However, science and engineering are highly interdisciplinary fields. To better equip students to engage in the interdisciplinary nature of real-world STEM research and practice, projects can be used to highlight the interconnectivity of core subjects. Here, we present an exploratory, guided inquiry classroom research project. This work details student-led experiments combining physics and chemistry principles to fabricate silicone bouncy balls and analyze resulting mechanochemical relationships in these elastomeric materials. In this project, students embodied researchers to uncover foundational relationships among chemistry, physics, and mathematics. To do this, students used silicone kits to design an array of polymer formulations resulting in bouncy balls of varying stiffnesses. Students aimed to answer a physics-based research question using chemistry and mathematics. The resulting data was used to discuss the effect of polymer chemistry on the behavior of the bouncy balls. This exercise serves to combine hands-on fabrication methods with quantitative analysis, using experimental methods of varying costs and complexities that can be tailored to instructor time and budget. The project presented here is appropriate for upper-level high school students or first-year undergraduates. The pedagogical goal of the work is to empower students to realize and use connections between chemistry, physics, polymer science, and engineering to understand the process of material design and selection.
