Over the past 10 years, I have been involved in educational outreach activities, such hands-on workshops, which serve college-level and pre-college biology educators. One goal of these activities has been to develop and share new methods for using invertebrates in biology classroom investigations. One result has been development of numerous, innovative, low-tech tools and gadgets that enhance abilities of teachers and students to collect, handle, view, and experiment with small, living invertebrates. I gratefully acknowledge support and inspiration of many teacher colleagues, who regularly give credence to the well-known saying, Necessity is the mother of invention (credited to Plato).
Students in my invertebrate biology course routinely and enthusiastically use these tools for collection, handling, observation, and investigative study of small aquatic and terrestrial invertebrates. I expect these tools to be useful in general biology lab teaching at all levels. [For more tools and related resources, see: www.eeob.iastate.edu/faculty/DrewesC/htdocs/
Since tool assembly is time-consuming and involves careful use of sharp instruments, I suggest making tools before rather during class. It is helpful to provide each student group with a small container for protective storage and convenient access to these tools and materials.
