Egg, larva, pupa, adult, done! How easy it would be if teaching students to grasp the nature and role of change was that simple! Getting students to observe and attend to the changes around them—in their natural surroundings and in the laboratory—is not a simple task. Change is not a “once and done” topic; it must be a conceptual thread that is continuously woven in all topics in science. Students must examine both long and short-term changes; the evolution of butterflies as well as their metamorphosis, plate tectonics as well as overnight storm erosion, climate change as well as the changeability of daily weather. This collection of articles will help you weave threads of change into your specific science content.
