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

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.

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
