Tardigrade Species Distribution Project: Lesson Plan
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 tartigr
Nanobacteria: Are They or Aren't They Alive?
This California State University lesson plan contains materials for a five-part activity regarding whether or not nanobacteria are alive. The case-study based activities include: What does it mean to be alive?; What evidence is there that nanobacteria are alive?; More evidence of life; Corroborating evidence (?); and The final chapter (or is it?). The website contains pertinent general information articles and resource lists for students as well as homework assignments based on readings. An answ
Microbiology Unit
This College level Unit in Microbiology explores microbes on five levels, their architecture, ecology, physiology, lifecycles and pathology. Students will be given an interactive tour of the world of microbes and learn more about their impact on Humans, animals, plants and on the environment in general. They will become aware of pathogenic (harmful) and non-pathogenic (helpful) microbes and develop an understanding of how microbiologists devise methods to study microbes in order to understand th
Invertebrate Anatomy OnLine
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, especia
Extreme 2002: Mission to the Abyss
This is the expedition page of the 2002 Mission to the Abyss. Developed by the University of Delaware Graduate College of Marine Studies, the site highlights the mission and crew, seafloor geology, creature features, and high-tech tools used in the study. This interactive website allows students to explore the submersible Alvin, find out how hydrothermal vents form, define the deep ocean, study plate tectonics, and meet hydrothermal vent organisms. The site includes extreme experiments, includin
Creatures that "glow" in the night
This Wisconsin Center for Environmental Education activity (PDF) encourages students to practice experimental design and scientific writing through the study of bioluminescence. Students observe and experiment with bioluminescent dinoflagellates (Pyrocystis fusiformis), learning how and why they produce light. The activity includes information for teacher preparation, an introduction to bioluminescence, defined vocabulary terms, a list of necessary materials, procedure, assessment questions, and
Bioinformatics Homework Assignment: Accessing and Analyzing Nucleic Acid Sequence Data from NCBI's D
This undergraduate activity introduces students to bioinformatics. During the guided activity students will access the National Center for Biotechnology Information's (NCBI) genetic sequence database to obtain and study DNA sequence entries relating to the chicken ovalbumin mRNA and genomic sequences.
Water Transparency Protocol
The purpose of this resource is to determine the transparency of water. Students measure water transparency at their undisturbed study site using a transparency tube or Secchi disk.
WeatherHawk Weather Station Protocol
This resource provides instructions on how to log atmosphere data using a WeatherHawk weather station. A weather station is setup to measure and record atmospheric measurements at 15-minute intervals and can be transferred to the GLOBE program via email. Students can view data for their school that are continuous and show variations within a day. The data collected includes wind speed and direction and pressure thereby supporting a more complete study of meteorology using GLOBE. Students pursue
Land Cover Change Detection Protocol
The purpose of the resource is to investigate changes in the major land cover types of Study Sites by examining Landsat satellite images acquired years apart.
Connecting the Parts of the Study Site
The purpose of this resource is to help students articulate and integrate their existing knowledge about the air, water, soil, and living things by viewing them as interacting parts of a system. Students visit a study site, where they observe and recall their existing knowledge of air, water, soil, and living things to make a list of interconnections among the four Earth system components. They make predictions about the effects of a change in a system, inferring ways these changes affect the ch
Representing the Study Site in a Diagram
The purpose of this resource is to help students learn the skills and value of the translating complex interactions among Earth System components into a simplified diagram. Students visit a study site, where they observe and recall their existing knowledge of air, water, soil, and living things to make a list of interconnections among the four Earth system components. They make predictions about the effects of a change in a system, inferring ways these changes affect the characteristics of other
Using Graphs to Show Connections
The purpose of this resource is to show how graphs of GLOBE data over time show the interconnectedness of Earth's system components at the local level. Students visit a study site, where they observe and recall their existing knowledge of air, water, soil, and living things to make a list of interconnections among the four Earth system components. They make predictions about the effects of a change in a system, inferring ways these changes affect the characteristics of other related components.
Comparing the Study Site to One in Another Region
The purpose of this resource is to deepen students understanding of the Earth as a system, and their appreciation for the value of diagrams as tools. Students visit a study site, where they observe and recall their existing knowledge of air, water, soil, and living things to make a list of interconnections among the four Earth system components. They make predictions about the effects of a change in a system, inferring ways these changes affect the characteristics of other related components.
Limiting Factors in Ecosystems
The purpose of this resource is to understand that physical factors - temperature and precipitation - limit the growth of vegetative ecosystems. Students observe and record seasonal changes in their local study site. They establish that these phenomena follow annual cycles and conclude the activity by creating displays that illustrate the repeating pattern associated with the appearance and disappearance of seasonal markers.
Significant Figures
This webpage is an overview of significant figures and their use in scientific notation. A chemistry tutor in the College of Math and Sciences at a public university developed this overview as one of several study aids for undergraduate chemistry students.
Community Health Nursing
By the end of this course the students should be able to: Identify the root of Community Health Nursing; identify supportive organizations; differentiate between Public Health Nurse and Community Health Nurse; explain Community Health Nursing; describe the qualities of the Community Health Nurse; describe the different types of community; differentiate between urban and rural communities and outline community profile; explain community entry; describe the preparations made before a community is
Electric Field Hockey
Play hockey with electric charges. Place charges on the ice, then hit start to try to get the puck in the goal. View the electric field. Trace the puck's motion. Make the game harder by placing walls in front of the goal. This is a clone of the popular simulation of the same name marketed by Physics Academic Software and written by Prof. Ruth Chabay of the Dept of Physics at North Carolina State University.
Finding Common Ground
Finding common ground helps students make informed decisions to conserve temperate forests in the United States and central China, habitat of the endangered giant panda. Through classroom activities, on-line simulations, and field investigations students learn about the important role temperate forests play in local and global ecosystems. Action steps culminate in a Class Conservation Action Plan.
In the course of this curriculum students locate the biome in which they live, explore a local habi
