This is a set of animal behavior investigations in which students will practice scientific inquiry as they observe crayfish, ask questions, and discuss territoriality, social interactions, and other behaviors. In doing this, they hone their skills of observation, learn to record and analyze data, control for variables, write hypotheses, make…

Most biology students have the opportunity to look at protozoa under the microscopes or keep mealworms in a bowl. They may manipulate the heart rate of "Daphnia" or calculate the respiration of plants. They may even grow corn in the spring or keep fish and a small rodent or two. But once the class hamster grows testy from being awakened every…

Conducting observational investigations of behaviors and processes is an important method for generating scientific knowledge. This article describes a methodology for assisting students in the processes of observational inquiry and theory articulation and its instantiation in a set of digital video tools. We describe a high school biology…

Biology teachers in introductory and upper level high school courses generally present principles of taxonomy as part of the curriculum. Students learn about classification systems that categorizes species into recognized taxonomic groups based on their degrees of structural divergence or derived ancestral traits. References made, hereafter, to…
