Marine Microbial Ecology
This image-rich website from the Australian Antarctic Division's Biology program describes its research in marine microbial ecology. It includes an introduction of microbial ecology and microbial processes, followed by information about the research project. Field sampling, microscopy, flow cytometry, pigment analysis, flourometry, HPLC, culturing, feeding experiments, and the research staff are each discussed using vivid imagery. Links are provided to related websites.
Water Quality For Freshwater Organisms
This website features a field activity that demonstrates the effect of water temperature on the solubility of dissolved oxygen and how it relates to the gill beat rate of fish. The activity uses the Winkler method to measure dissolved oxygen.
Resources for looking at art
A guide to some of the best websites, activities, and print resources for building visual literacy through the study of art.
How mentors can serve as role models, helpers, and colleagues.
Water-Resources Reconnaissance of the Southeastern Part of St. Paul Island, Pribilof Islands, Alaska
This 12-page PDF was prepared by the USGS to investigate sources of water and groundwater quality on St. Paul Island in order to design a well field without inducing saline water. Tables, diagrams and maps accompany the text.
Magnets and Electromagnets
Explore the interactions between a compass and bar magnet. Discover how you can use a battery and wire to make a magnet! Can you make it a stronger magnet? Can you make the magnetic field reverse?
Quantum Bound States
Explore the properties of quantum "particles" bound in potential wells. See how the wave functions and probability densities that describe them evolve (or don't) over time. Teacher's guide available.
Radio Waves & Electromagnetic Fields
Broadcast radio waves from KPhET. Wiggle the transmitter electron manually or have it oscillate automatically. Display the field as a curve or vectors. The strip chart shows the electron positions at the transmitter and at the receiver.
Quantum Wave Interference
When do photons, electrons, and atoms behave like particles and when do they behave like waves? Watch waves spread out and interfere as they pass through a double slit, then get detected on a screen as tiny dots. Use quantum detectors to explore how measurements change the waves and the patterns they produce on the screen.
The Photoelectric Effect
See how light knocks electrons off a metal target, and recreate the experiment that spawned the field of quantum mechanics.
Sampling is a computer tool designed to help biology students obtain a qualitative understanding of basic concepts related to estimation and statistics. Sampling presents the user with a group of hypothetical populations distributed throughout an area, and with tools for sampling these populations to estimate characteristics such as population size and density, the nature of each population's spatial patterning, and spatial correlations in abundance between populations. By manipulating the numb
This interactive L-system simulation produces visualizations of tree forms based on data from specimens in the field or laboratory.
Digital Government 1: Information Technology and Democratic Politics, Winter 2009
Course is the first in a two-part sequence exploring contemporary practices, challenges, and opportunities at the intersection of information technology and democratic governance. Whereas the second course focuses on challenges and innovations in democratic administration, this first course focuses on theories and practices of democratic politics and the shifting role of information technologies in supporting, transforming, and understanding these. The first half of the course seeks to ground co
Digital Government I: Information Technology and Democratic Politics, Winter 2007
This seven-week course is the first in a two-part sequence exploring contemporary practices, challenges, and opportunities at the intersection of information technology and democratic governance. This first half of the course focuses on theories and practices of democratic politics and the shifting role of information technologies in shaping, transforming, and understanding these. The course seeks to ground contemporary discussions around IT and politics in various flavors of democratic, polit
eCommunities: Analysis and Design of Online Interaction Environments, Winter 2009
Gives students a background in theory and practice surrounding online interaction environments. For the purpose of this course, a community is defined as a group of people who sustain interaction over time. The group may be held together by a common identity, a collective purpose, or merely by the individual utility gained from the interactions. An online interaction environment is an electronic forum, accessed through computers or other electronic devices, in which community members can conduct
Networks: Theory and Application, Fall 2008
This course covers topics in network analysis, from social networks to applications in information networks such as the internet. It introduces basic concepts in network theory, discuss metrics and models, use software analysis tools to experiment with a wide variety of real-world network data, and study applications to areas such as information retrieval.
Viewing the Periodic Table of the Elements with X-rays
X-rays and x-ray fluorescence are not new subjects to the field of physics. Wilhelm Röntgen discovered x-rays in 1895, and in 1901 he was awarded the very first Nobel Prize in physics for this discovery. Soon after, Charles Glover Barkla discovered that each element has its own characteristic x-ray spectrum. He was awarded a Nobel Prize in physics for this discovery in 1917. Sir William Henry Bragg and his son, Sir William Lawrence Bragg, were then able to experimentally prove that the discrete
AP Physics B
This curriculum covers all of the material outlined by the College Board as necessary to prepare students to pass the AP Physics B exam. This course is divided into two semesters and is designed to acquaint you with topics in classical and modern physics. The first semester discusses topics in Newtonian mechanics including: kinematics, laws of motion, work and energy, systems of particles, momentum, circular motion, oscillations, and gravitation. The first semester concludes with topics in fluid
Poker and Strategic Thinking
In this course we will work from the idea that there is merit in a poker way of thinking when analyzing real life situations. We think the skills important to playing winning poker, and ideas behind these skills, have merit in other fields. The goals of the course are to introduce the use of ideas from the poker world in skills of life, business, politics and international relations. We will specifically delve into the use of poker in: 1.Strategic thinking 2.Game Theory, Risk and Business 3.So
Peer 2 Peer University
The Peer 2 Peer University (P2PU) is an online community of open study groups for short university-level courses. Think of it as online book clubs for open educational resources. The P2PU helps you navigate the wealth of open education materials that are out there, creates small groups of motivated learners, and supports the design and facilitation of courses. Students and tutors get recognition for their work, and we are building pathways to formal credit as well. Currently P2PU is in a pilot
