The Goldilocks Zone
This is an article from "Teachable Moments in the News," a newsletter that takes recent Earth and space science related news stories and places them in a context relevant to the science curriculum. This particular edition describes the Goldilocks Zone, a range of environmental conditions that can support life. Teachers are provided a brief introduction, relevant news links, and developed lesson plans. Some lessons are in PDF format. Activity themes include: exploration of environmental condition
Water Vapor Protocol
The purpose of this activity is to measure the total precipitable water vapor (column water vapor) in the atmosphere above an observer's site. Students point a GLOBE/GIFTS water vapor instrument at the sun and record the voltage readings from a digital voltmeter. They observe sky conditions near the Sun and perform the Cloud Protocols. Intended outcomes are that students understand the concept that the atmosphere prevents some of the sun's light from reaching Earth's surface, how water vapor mea
Soil: The Great Decomposer
The purpose of this resource is to understand that soil, under different environmental conditions, plays a role in the decomposition of organic materials. Students use bottle experiments to observe changes in the decomposition of vegetable scraps. Students vary temperature, moisture, and light conditions to determine the conditions that best facilitate the decomposition of organic material in soil.

Introduction to Business
BU100 - Introduction to Business
The BU100 Introduction to Business course provides a fundamental working knowledge of the varied aspects of business and prepares you for future studies in more specialized topics within the subject area. You will increase your awareness of the overall environment and function of business as well as observe its contributions to society. This course also covers communication technology, globalization, and business ethics.
Hurricane Katrina Impact Studies
This website is a cooperative research project between the U.S. Geological Survey (USGS), NASA, the U.S. Army Corps of Engineers, and the University of New Orleans. The goal of the project is to investigate coastal change that occurred as a result of Hurricane Katrina. The site includes aerial video, still photography, and laser altimetry surveys of post-storm beach conditions that were collected August 31 and September 1, 2005 for comparison with earlier data. The comparison data can be used to
Geothermal Energy and Geysers
This web page, created by the US Energy Information Administration, gives a description of geysers, where they are found, the conditions that create them, and the process of their eruptions. The geysers of Yellowstone National Park are described as the best collection of geysers in the world. The author notes that geothermal energy can be derived from geyser fields, but geothermal electricity production depletes the geysers' water and removes some of the available heat, reducing and sometimes de

20.441J Biomaterials-Tissue Interactions (MIT)
This course covers the principles of materials science and cell biology underlying the design of medical implants, artificial organs, and matrices for tissue engineering. Methods for biomaterials surface characterization and analysis of protein adsorption on biomaterials. Molecular and cellular interactions with biomaterials are analyzed in terms of unit cell processes, such as matrix synthesis, degradation, and contraction. Mechanisms underlying wound healing and tissue remodeling following imp
Decoding the Past: The Work of Archaeologists
This site introduces students to archeology -- the study of material remains to learn about past human experiences. This lesson (Grades 3-8) discusses various challenges of an archaeologist: locating a site that will yield clues about the people who once lived there, conducting excavations, and more. Students identify artifacts from a contemporary setting, describe the function of each artifact, identify methods for dating soil layers, and interpret soil profiles.
QM Eigenstate Superposition Demo Model
The EJS QM Eigenstate Superposition Demo model displays the time dependence of a variety of superpositions of energy eigenfunctions for the infinite square well and harmonic oscillator potentials. One of the eleven pre-set superpositions can be selected via a drop-down menu with the resulting wave function shown in phase-as-color representation. A table of the expansion coefficients is shown and can be edited. The width of the infinite square well potential can be changed via a slider.
Lennard-Jones Potential Model
The EJS Lennard-Jones Potential model shows the dynamics of a particle of mass m within this potential. You can drag particle to change its position and you can drag the energy-line to change its total energy.
The Lennard-Jones potential function is a reasonably accurate model of interactions between noble gas atoms. The binding energy epsilon is the depth of the potential well and minimum molecular separation are set equal to unity. This simulation uses uses a natural system of units the m
Radioactive Decay Model
The EJS Radioactive Decay Model simulates the decay of a radioactive sample using discrete random events. It displays the number of radioactive nuclei as a function of time. You can change the initial number of nuclei and the decay constant as well as changing the plot to a semi-log plot.
Balls in a Box Model
The Balls in a Box model shows a system of particles is very sensitive to its initial conditions. In general, an isolated system of many particles that is prepared in a nonrandom configuration will change in time so as to approach its most random configuration where it is in equilibrium. What happens if we choose the initial conditions in a very special way?
The default initial condition corresponds to eight stationary particles perfectly aligned on the x-axis. Two particles approach from the l
Ejs Wave Representations Model
The EJS Wave Representations model displays two representations of a sinusoidal wave on a string. One shows a movie of the wave traveling along a string - you can think of this representation as a sequence of photographs. The second representation is a plot of the displacement as a function of time for two points on the string (you can select which two points to use). Using only these two representations, you can determine the values of many different parameters that describe the wave.
Virtual yeast cell
This rich learning object is used to introduce yeast cytology to students taking Module D24BS3 Brewery Yeast Management as part of the MSc in Brewing Science. The virtual cell permits the students to understand structure and function of yeast organelles.

Introduction to compact operators
The aim of this session is to cover the basic theory of compact linear operators on Banach spaces. This includes definitions and statements of the background and main results, with illustrative examples and some proofs.
Target audience: This material is accessible to anyone who has a basic knowledge of metric space topology, and who knows what a bounded linear operator on a Banach space is. It is most likely to be suitable for postgraduate students or final year undergraduates.
Tracing Genetic Ancestry Using DNA Microarrays
In this lesson students will read and discuss an article about genetic ancestry and genetic ancestry testing. 2. Apply knowledge of DNA and heredity to understand DNA microarrays, and concepts of genetic mutation and ancestry tracking. 3. Mimic the function of a DNA microarray used for genetic ancestry analysis by completing a paper-and-pencil activity. 4. Discuss the ethics of genetic testing in medical research.
Kamchatka: Siberia's Forbidden Wilderness
These lessons are designed for earth science and biology students in middle and high school classrooms, though extension suggestions for older and younger students will allow you to adapt each lesson for younger and older audiences. The lessons are designed to complement the Living Edens: Kamchatka program; each lesson will indicate clips from the program that focus on the topic at hand, though the lessons function equally well as stand-alone content.
