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.
Inelastic Collision of Particles with Structure Model
The EJS Inelastic Collision of Particles with Structure model displays the inelastic collision between two equal "particles" with structure on a smooth horizontal surface. Each particle has two microscopic elements which interact through a massless spring of stiffness k and natural length L. The mass of one of the microscopic elements and the spring length of the connector spring can be changed via textboxes. You can modify this simulation if you have EJS installed by right-clicking within the p
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.
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.
China - EU Relations in a Changing New World
The world today is undergoing tremendous development, changes and adjustments. The international community is facing increasing opportunities and challenges. The present international system and structure are not able to cope with this new situation fully and effectively, and reform is the general demand of the world people at large. Both China and UK are global actors of significant importance. How the two countries should behave in handling the situation? It is a fact that China and UK are dif
How to write essays
This resource includes content and activities about writing essays. It presents information and examples related to understanding the topic and the use of structure, evidence and language.
This lesson provides an overview of basic atomic structure and the concept of radioactive decay. Topics include the particles that make up an atom, binding forces, and the concept of isotopes. There is also discussion of decay methods and half-life.
This exercise is intended to reinforce the importance of Earth's atmosphere to living organisms. Topics include our bodies' interactions with the atmosphere; its composition and structure; and natural changes in the atmosphere (weather).
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.
Star Library: Regression - Residuals - Why?
As teachers of statistics, we know that residual plots and other diagnostics are important to deciding whether or not linear regression is appropriate for a set of data. Despite talking with our students about this, many students might believe that if the correlation coefficient is strong enough, these diagnostic checks are not important. The data set included in this activity was created to lure students into a situation that looks on the surface to be appropriate for the use of linear regressi
Environmental Decision Making
Using the Extend 'connect-the-components' visual programming, students can model and simulate ecosystems including social and economic forces as well as study parameter variations to develop an understanding of ecosystem function and productivity. By making 'what if...' changes in the model, the effects of various proposed decisions about the environment can then be shown. EDM includes three ecological systems: Ponds, Grasslands, and Logging. Students can predict results of changes in the mode
Bering Sea Climate
The Bering Sea Climate website contains time series data that measures climate and ecosystem status in the Bering Sea. The site presents data, metadata, and graphics by allowing the user to select categories and then click a button for the desired function. Data can be displayed as a list, a time series plot, or in terms of recent trends, relevance, and correlation. Measured parameters include weather, oceanographic and climate data, sea ice data, and fisheries and other biological data. The sit
Building Bridges, Dams, Power Plants
The large development projects of the 1930s, designed to serve a growing population, helped shape California in many ways. Most are still integral today. Photographs show the progress of two massive Northern California projects: the Golden Gate Bridge, which links San Francisco and Marin County, and the Bay Bridge, which connects San Francisco with Oakland and the East Bay. The Golden Gate Bridge is one of the most recognized bridges in the world. It is unique not only because of its vermilion o
Medicine Games: Incredible Megacell Game
Play a game and find out about a Nobel Prize awarded discovery or work! The compartments of the cell, the organelles, are so small that it was impossible to study their structure until the electron microscope became available in 1938. Albert Claude, Christian de Duve and George E. Palade were awarded the Nobel Prize in Physiology or Medicine in 1974 for developing methods making it possible to take a closer look at the organelles and for discovering some of them.
Patient Communication Skills, 2009
The materials on this page represent a curriculum for teaching effective patient communication to dentistry students. These techniques could be useful for other healthcare providers, as well: medical students, nursing students, public health providers, and in-practice health care providers. There are two main types of resources: performance keys and videos. Performance Keys are text documents that articulate key patient interaction skills, and give examples of more and less effective techniques
