Polymers Course for Small Colleges and Universities

Journal of College Science Teaching—September/October 2018

By Joseph Furgal

This article describes the course design and teaching methodology for a polymer chemistry and applications lecture class specifically aimed at small college and university instruction. This intermediate course for advanced undergraduates and masters-level graduate students focuses on teaching the basics of polymer history, synthesis, and characterization with connections to the core chemistry curriculum in a small-class-size environment and without a textbook. Furthermore, an extensive overview of the applications of polymeric materials gives students a connection to real-life applications. The course includes polymer case studies, informational lessons on realworld objects made of polymers, and demonstrations. Student presentations on how polymers are important to society help connect the course to the world around them. The course is designed to instill the knowledge necessary for students to be successful in a career in polymers. A brief discussion of course reflections and student input is also given.

Instructional Sequence Matters shows how to make simple shifts in the way you arrange and combine activities to improve student learning. It also makes it easy for you to put the NGSS into practice. After explaining why sequencing is so important, author Patrick Brown provides a complete self-guided tour to becoming an “explore-before-explain” teacher.

When the authors of this book took part in Project INFUSE, the National Science Foundation–funded teacher development program, they noticed something. Life science teachers were highly receptive to engineering ideas related to everything from genomic testing to biofuels. But they also saw that teachers struggled to develop age-appropriate, standards-based lessons. The teachers asked for help facilitating the kind of open-ended design challenges that are useful to presenting engineering concepts in quick, engaging ways.

Ephemeral art exploring properties of matter, natural materials

By Peggy Ashbrook

Posted on 2018-08-31

Child stirs a bucket of water with flowers and leaves floating in it.I had fun this summer spending 4 days over 2 weeks “enriching” preschool teachers and children in their program by collaboratively exploring ephemeral art projects. Good discussion about when children’s making becomes art was part of our work together. Does mixing up a colorful mud-grass-flower-water “stew” or chopping (sculpting?) a rotting log with plastic trowels count as art? What do you think?

Children chopping at a rotting log with plastic tools.While experiences and subsequent discoveries are important, I don’t call it art unless the children are intentional about designing the look, smell, feel, or sound of it. Or if they identify some intentions afterwards (“It looks like a…”). I can see the science learning in children’s random and open exploration actions but I wouldn’t call these art. The open-ended work builds understanding as they make connections between prior experiences and accidental discoveries. In the stew the stones sink, flowers float, and the water gets more opaque as soil is added. Petals are easier to tear apart than stems, each contributing a different color and texture to the mix. As the rotting log comes apart, the inner color is lighter than the outside…”Why?” “I think it’s because the rain.”

Children painting with water on stones.The ephemeral art work included painting with water, temporary structures of rock, sticks set into sand and their shadows, painted leaves and burlap, and a clay structure embellished with shells and sticks. Discussion with the children as they worked let them know that some art work we make doesn’t get saved to take home. Our photographs can “save” the work for us before “unbuilders” disrupt it or time and natural weather events make changes.

Children's bridge structure built of stones set on top of each other.The children built “bridges” using different shapes and types of rock, exploring the properties of rock and how shape affects how a rock can be part of a structure. The rocks provided a different kind of experience but required close supervision as this new-to-the-school material was heavier than most others usually available (I asked children to use two hands to lift the rocks). My hope is that with experience, some classes at the school will be able to incorporate the stones into the sandbox play.

Redbud tree leaves painted with tempera paint.Children and teachers were surprised that we could paint on leaves picked from trees. The smooth Redbud tree leaves made mini canvases. We pinned them up on a wall and the images changed with time, sunlight, and rain. I was relieved when the children did not get upset at the changes—they accepted the idea of ephemeral more easily than I expected.

Burlap bags, donated by a local coffee roaster, worked well for two purposes: a painting canvas and base for a structure/sculpture. I thought a group experience painting with tempera might make children less concerned about having their work changed by leaving the canvas hung up outside over a week of rainstorms and sunshine. Adding more paint was the main point for many but a few children focused on where they added paint. Changes to the work will be easy to notice when comparing photos of newly-created work with photographs taken weeks later.

Three, four, and five-year-olds contributed their ideas and effort to creating a structure using a stump and sticks covered with burlap as the base. Children and teachers pressed gray potters clay into the burlap, wetting it to make it stick. On a nearby stump they used play kitchen knives to cut up slabs of clay, switching to a spatula action, pressing and rubbing when adding the clay to the structure. Once all available clay became part of the structure (I still hesitate to call it a sculpture), children began embellishing it with sticks and stones from the play area and shells from someone’s beach vacation.

Teachers talked with children about observed changes in the paintings due to leaves drying and curling, and rain streaking the paint as it soaked the burlap canvas. “Oh, okay,” was the reaction of most children. Perhaps because they were more intimately involved with the structure through their hands-on manipulation of clay, they earnestly called teachers’ attention to cracks forming as the clay dried, and discussed whether or not to pick it apart. (Opinions were divided so teachers said the plan was to keep it intact.) After a heavy rain re-softening and drooping the clay covering the burlap, children added more shells and sticks, making the structure more of a sculpture in my eyes.

With more clay, sand, straw, and more time, children could make a larger, more permanent sculpture using a “cob” process.  Always Becoming,” by artist Nora Naranjo-Morse (Santa Clara Pueblo) is an example of sculptures that change over time as they stand in the elements outside the National Museum of the American Indian in Washington, D. C. 

The play area is open to the public after school hours so it is unlikely the sculpture structure will survive very long. The children will retain their experiences of the absorption of paint into burlap, texture of leaves, blocking light to create shadows, clay becoming slippery with water, pushing clay between the burlap fibers, sticks and shells sticking into clay, and rain altering clay. These experiences help them build their understanding of the properties of matter, structure of leaves, shadows, effects of weather events, and the idea that they can manipulate matter to create artwork, or something.
