In this article we describe a multi-week investigative laboratory in microbial ecology/diversity and nitrogen cycling that we have used in our introductory biology course. This module encourages active student involvement in experimental design, using the scientific literature and quantitative analysis of large data sets. Students analyze soil…

Presents investigations of leaf surface wetness that provide ideal opportunities for students to explore the relationships between leaf form and function, to study surface conditions of leaves and plant physiology, and to make predictions about plant adaptation in different environments. Describes simple procedures for exploring questions related…

Applying botanical knowledge to a simulated forensic investigation provides inquiry-based and problem-based learning in the botany classroom. This paper details one such forensic investigation in which students use what they have learned about plant morphology and anatomy to analyze evidence and solve a murder mystery. (Contains 1 table.)

Presents activities that use the learning cycle to engage students in meaningful inquiries in the study of Mendelian genetics. Includes content-related background and teaching tips for each phase of the learning cycle. (JRH)

Outdoor education, which should be complementary to classroom work, is all of that learning which takes place in and about the outdoors. This book, which is aimed primarily at teachers and student groups, is a useful aid to those who may wish to investigate and explore the rich natural outdoor environment and consists of investigations which are…

This book of life science activities introduces a new experimental animal--the WOWBug, "Melittobia digitata"--that is commonly found in nature but has never before been used in the precollege classroom. It includes 20 activities and experiments for grades 5-12, that cover topics from basic orientation to ecological interactions, from physical…

Presents a learning cycle lesson plan in which students investigate the question of how cells divide. Students use microscopes to explore actual plant root and stem tissues to generate and test hypotheses to answer the question. Includes teacher material, student material, and teaching tips. (MDH)

The slime trails of snails lead the author's students to a better understanding of science as inquiry and the processes of science. During this five-day activity, students get up close and personal with one of her favorite creatures, the land snail. Students begin by observing the organism and recording their observations. After making initial…

Presents an activity in which students in grades 5-8 learn about snail reproduction by observing and charting the activities of land snails, freshwater snails, and slugs. Instructions to implement and extend the activity are provided. (MDH)

Studying "Caenorhabditis elegans" ("C. elegans") live cultures provides excellent opportunities for authentic inquiry in a high school anatomy and physiology or other biology lab course. Using a digital dissection microscope, a student can photograph the organism during various stages of development and study and analyze the images. In this…

Describes the use of cross-age tutoring in which sixth-grade students are used to teach first-grade students about plants. Provides a list of praise words used by the sixth graders and discusses the mutual benefits received by the students. (MDH)
