In this article, fourth graders investigate the physical and behavioral adaptations of crayfish. Because crayfish are native to the area and many students have experience observing them in local streams, the author decided to use these organisms to explore the relationship between the structure of their various body parts and how those structures…

An important part of promoting scientific literacy is developing disciplinary literacy practices, such as obtaining information from text and sharing investigation results through talk and writing. To support students to develop disciplinary literacy practices in science, educators must provide opportunities for them to work with multiple…

Dinosaurs are one of those science topics that draw children in and teach them about concepts like measuring and using descriptive language. Learning about dinosaurs, although not hands-on like observing and recording caterpillar growth, develops critical thinking and introduces animal diversity and the relations between body form and function.…

How do you inspire students to keep records like scientists? Share the primary research of real scientists and explicitly teach students how to keep records--that's how! Therefore, a group of third-grade students and their teacher studied the work of famous primatologist Jane Goodall and her modern-day counterpart Ian Gilby. After learning about…

Children can have a new favorite animal every week or even every hour. The more familiar the children become with an animal, the more they will be able to understand how its body form and behavior allow it to survive. Learning about the characteristics of organisms and how organisms relate to their environment is part of the National Science…

Crayfish, also known as "crawfish" or "crawdads," are easy to keep in the classroom, and with patience and luck, students will observe the complete life cycle of the crayfish. They will also learn about aquatic animals and habitats and get to conduct inquiry experiments about animal behavior. This article describes how a third-grade teacher used…

Describes the distinctive features of the common snapping turtle. Discusses facts and misconceptions held about the turtle. Provides guidelines for proper care and treatment of a young snapper in a classroom environment. (ML)

Describes the habitats and life cycles of newts. Provides tips on collecting and caring for newts, along with suggestions for observational lessons related to the collection, study, and release of these organisms. (TW)

Describes having a pot-bellied pig in a classroom. Students learned how to care for the pig and train it. Describes other animals in the classroom and the class putting on shows for other students. (PR)

Provides suggestions for activities that focus on earthworms. Includes observational exercises on earthworms' reactions to light and touch. (ML)

Describes some of the characteristics of the common harvestmen, or daddy longlegs, and the true spider. Provides information on harvestmen's habitats and life cycles and includes tips on housing and observing these organisms in science classrooms. (TW)

Directions are given for caring for desert tortoises, both adults and young. Observations of their behavior are recommended. (SA)

Presents lessons to stimulate children's interest in science and develop communication skills by having students simulate the locomotion of an ameba, a paramecium, and an Euglena, and the cyclosis in the pondweed Elodea. Students practice communication skills by demonstrating their organism to the remainder of the class. (MDH)

Presents an activity that teaches children the language of the honeybee--and which transforms the classroom into a honeybee colony. Children mimic the foraging behavior of honeybees and learn to appreciate the importance of community effort among animals. (PR)

Describes a field study of dragonflies and damselflies. After a bit of background reading and equipped with paper, pencil, insect net, and work sheet in hand, students will come to appreciate the behaviors of these insects as they gain a deeper understanding of the natural world. (PR)
