My school’s science team realized our students could learn about physical changes and physical properties using glass tubing. We purchased one meter long glass tubing from one of our science supply sources. Students observed me demonstrate how to heat the glass until it became “soft” and would gently bend. I showed how the tubing could be bent into circles, angles, and wrapped around itself. Students then applied the concepts as they created their own “silly straws” using the glass tubing.
Safety concerns for this activity included:
Students were allowed to create their own designs. One of my favorite looked like the edges of four pieces of a jigsaw puzzle.
