This Gulf of Maine educational website takes students aboard the submersible Alvin. Classroom activities explore nautical and mythical names, such as the Titanic, instruct students how to make a model of the ocean floor in a shoebox, and introduce topics such as deep sea vents and plate tectonics.

The Center for Food Safety and Applied Nutrition (CFSAN) prepared this online handbook on foodborne pathogenic microorganisms (bacteria, viruses and parasites) and natural toxins. Chapters are arranged under the following headings: Pathogenic Bacteria, Enterovirulent Escherichia Coli Group, Parasitic Protozoa and Worms, Viruses, Natural Toxins, Other Pathogenic Agents, and Appendices. The intent of each chapter is to provide basic facts regarding these organisms and toxins including their characteristics, habitat or source, associated foods, infective dose, characteristic disease symptoms, complications, recent and/or major outbreaks, and any susceptible populations. The chapters also contain minimal information on the analytical methods used to detect, isolate, and/or identify the pathogens or natural toxins.
The objective of this activity is to plot seven positions of an Autonomous Underwater vehicle (AUV) in the mapping area below, and track the AUV’s motion.
This Great Moments in Science radio transcript discusses the history of bioluminescence. It covers the first scientists to study bioluminescence, organisms capable of making light, biochemistry of the phenomena, and interesting stories. The audio version of this program can be downloaded and requires RealPlayer.
This Great Moments in Science radio transcript describes the three types of bioluminescence (bacterial, extracellular, and intracellular) and associated medical applications. The audio version of this program can be downloaded and requires RealPlayer.
This Great Moments in Science radio transcript describes photons of light (not to be confused with bioluminescence) that can be seen only with the most sensitive photodetectors. Scientists believe that this light might be used by cells to communicate with each other. The audio version of this program can be downloaded and requires RealPlayer.
This online laboratory manual features original anatomical descriptions of 112 species for use in invertebrate zoology teaching or research laboratories in North America. The collection was prepared over a period of many years to facilitate and encourage the study of invertebrate animals. It is a smorgasbord of species intended to provide a selection suitable for courses taught in most parts of North America. Many species, or their close relatives, also occur in other parts of the world, especially Europe. Although the chapters are written in laboratory manual format, they can also be used to support research or in other non-teaching situations as introductions to the anatomy of specific invertebrates. The anatomical descriptions are presented as laboratory exercises, many of which have been tested by my students in invertebrate zoology courses at Lander University, the Harbor Branch Oceanographic Institution, and the Duke University Marine Laboratory. These have benefited from numerous revisions based on many years of student use.
This on-line exercise is focused on lactic acid bacteria, a group of related bacteria that produce lactic acid as a result of carbohydrate fermentation. It includes a protocol for the enrichment of lactic acid bacteria from enriched samples (like yogurt, sauerkraut, decaying plant matter, and tooth plaque). Three parameters are measured: growth, culture diversity, and pH. The exercise also includes instructions for the isolation of some of these bacteria by using the streak-plate method.

Welcome to the Teachers' Corner of Small Things Considered. In this section, we include the posts we deem most adequate for teaching purposes. We have reorganized them into subject areas geared for a typical microbiology course. To date, this material has been used for various forms of intellectual enrichment, e.g., suggested readings, class presentations, a source of topics for term papers. You can also find here our Talmudic Questions, which we characterize as those whose answers cannot be found in Google. We are told that some of these questions have been used in exams ranging from tests for undergraduate courses to qualifying/prelims for graduate students.
This EPA site provides links to introductory information about the Gulf of Mexico dead zone. It offers answers to questions such as: what is the hypoxic zone, how did it form, what strategies are being implemented to remedy it, and what is the government doing. It also features links to various regions within the Mississippi River Basin, allowing users to explore issues in their own area.
This online handbook features a downloadable PDF of pre-and post-visit activities for the Squid Lab, a traveling outreach program hosted by the National Aquarium in Baltimore. The hands-on activities and student sheets may be incorporated into any life science classroom. The Squid Lab begins with an overview of the cephalopods, with a particular emphasis on squid. The overall anatomy of the squid is also discussed to provide students with a preview of what they will see when the dissection begins. Students will learn about the adaptations, defense mechanisms, feeding habits, predators and reproductive strategies of squid. Step by step directions are given to guide the students through the dissection.
This online lesson plan was designed for students taking part in the active research project to document the distribution of a new species of tardigrade, a microscopic invertebrate animal. The project is part of a nationwide online collaborative research project. The lesson plan offers instructional procedures for teachers and lists materials and procedures for collecting, observing, and culturing tardigrades. The lesson involves collecting samples in the field, examining and classifying tartigrades in the samples using a microscope and an online taxonomic key, and keeping a biological journal of their study. Links are provided to other components of the species distribution project.
This online PowerPoint presentation is dedicated to the phylum Tardigrada. It discusses distinguishing characteristics of Tardigrades (also known as water bears), their relationship to arthropods and nematodes, internal structures, life stages, cryptobiosis, research opportunities, classification, identification, habitat, distribution, ease of study in the lab, and more. Each slide contains illustrations and descriptions of the microscopic animal.
These activities, in conjunction with Bigelow Laboratory's “Toxic and Harmful Algal Bloom" web site, will help your students gain a better understanding of toxic and harmful algal blooms. Each module below consists of background content material and related standards-based activities. Each module is independent of the others; however, some background knowledge is required to complete the lessons.
Teachers, learners and science enthusiasts are invited to explore Life on Earth and share their learning by building ToL treehouses and publishing them on the Tree of Life. Broadening our contributor base and audience is part of our efforts to create an open access digital library about biodiversity. The ToL provides four different ways of interacting with ToL learning resources, from the least interactive (browsing) to the most interactive (becoming a treehouse builder and creating ToL treehouse web pages).
Classrooms of all ages and individuals over 18 can become ToL learning materials contributors and learn how to make their own treehouse web pages using the ToL web-based Treehouse Editor. Treehouse builders will create, access and use digital media: images, audio, movies, and text. Builders can publish treehouse games, stories, investigations, art and cultural pieces, biographies, and teacher resources on the Tree of Life. Builders will learn about phylogenetic biology, new places, organisms and projects and connect their work to the larger bioscience community.
This image-rich Streams.org website describes turbidity and total suspended solids (TSS). It includes overviews about what they are, why they are measured, how they are measured, and why they vary. The site also features links to sensor and other water quality parameters.
