Selected Simulations


DNA (Multimedia)
Models replication and protein synthesis in real time. This highly interactive simulation includes history timeline, information on the code, manipulation of the code, applications, and the genome.

Evolutionary Analysis
PhyloStrat shows what happens when species are independently designed versus evolved by descent with modification; EvoDots, explores the mechanism of evolution; FrogPon designs experiments that will establish the cause of deformities in a model frog population; PopCycle, explores the power of combining Mendelian genetics with Darwinian selection; AlleleA1 simulates evolution at a single locus in an ideal population of imaginary organisms; Bugsville simulates the genetics of a quantitative character; ForensicEA explores the logic of phylogeny reconstruction.

Students and teachers can manipulate the processes of inheritance on six different, but related, levels: DNA, chromosome, cell, organism, pedigree, and population. As a complement to text-based instruction, the CBM allows students not only to read about genetics, but actually observe and manipulate processes at one biological level that affect life at another. (K-12 but useful for college).

Hands on Genetics
Instructional software for basic genetics, such as DNA, PCR, Mendel, Hardy-Weinberg, meiosis and computer simulations.

Used to teach population biology and evolutionary ecology at the University of Minnesota.

Biomathematics Sally Blower Interactive Models of Transmission Dynamics
Models are used as health policy tools to understand and to predict the effect of different epidemic control strategies on the emergence of drug resistance and the effects of vaccination.


Chemical Collective
The Chemistry Collective is a collection of virtual labs, scenario-based learning activities, and concepts tests which can be incorporated into a variety of teaching approaches as pre-labs, alternatives to textbook homework, and in-class activities for individuals or teams. 

Dr. Mencer's Interactive Chemistry Activities
The pages within this site are designed to simulate experiments, allow the collection of data, and provide some guiding questions to help the user develop an insight into the phenomenon being studied.

Introduction to College Chemistry (aka General Chemistry)
This site offers chemistry experiment simulations, tutorials and conceptual computer animations.

Chemical Simulations on the Internet
Presents resources from the CONFCHEM Internet Conferenceon Chemistry.

Interactive Simulations of Basic Electronic and Operational Amplifier Circuits
This is a collection of real-time, theory-based interactive simulations of some simple electronic circuits.


FoilSim II includes a stall model for the airfoil and a model of the Martian atmosphere for lift comparisons; the Baseball Lessons, students learn more about aerodynamics by controlling conditions of a baseball pitch, including altitude(location), speed of pitch, and spin of pitch; EngineSim is a simulator that models the design and testing of jet engines and the effects of engine type on aircraft speed and range; Range Applet this program uses jet engines to present a variety of math and physics problems.

Introduction to Engineering Virtual Laboratory
The objective of the course and the virtual laboratory is to introduce students to experimentation, problem solving, data gathering, and scientific interpretation early in their careers.

Java Applets for Engineering Education
The applets fall into three main categories: statics, dynamics, and fluid dynamics. There are several specific topics in each of these sections, which demonstrate principles such as heat conduction, ideal flow, vector algebra, and projectile motion.

An agent-based approach to the exploration of materials science models.

The Nanohub
This is a resource for research and education nano-electronics, NEMS, and their application to nano-biosystems and the place where experiment, theory and simulation meet and move nanoscience to nanotechnology.

Semiconductor Applet Service
This site provides a large collection of simulations, animations, and tutorials on semiconductor and device physics, and semiconductor device manufacture and operation.


USGS Water Streamflow Conditions
Software, models, interactive links, real-time data for geographical areas in “US Daily Streamflow Conditions.” Links to Dist. of Columbia and Maryland.

Global Warming
Use this site to "Simulate Global Warming" by manipulating different variables and arriving at a formula for preventing polar meltdown.

A city simulation game. You are required to build and maintain a city. You must feed, house, and provide jobs and goods for your residents. You can build a sustainable economy with the help of renewable energy and recycling, or you can go for broke and build rockets to escape from a pollution ridden and resource starved planet, it's up to you.

The SimForest
Students can plant trees from a pool of over 30 regional species, set environmental parameters such as rain fall, temperature, and soil conditions, and watch the forest plot grow and evolve over many years. Graphing and analysis tools are provided to make inquiry more efficient.

This software-based simulation model is for integrated planning and analysis of urban development, incorporating the interactions between land use, transportation, and public policy. It is intended for use by Metropolitan Planning Organizations and others needing to interface existing travel models with new land use forecasting and analysis capabilities.


Interactive java applets demonstrate concepts from calculus, includes limits, derivatives, and integrals.

Digital Classroom Resources (DCR)
Learning materials in DCR might involve, but are not limited to, one or more of the following technologies:  interactive web pages using Java applets, JavaScript, free browser plug-in, or cgi or other server-side applications; web pages enhanced with animation or streaming video, preferably with some interactivity built in; downloadable programs that run independently of the web or web browser; or modules developed for commercial computer algebra systems like Maple, Mathematica, MatLab, or others.

Culturally Situated Design Tools: teaching math through culture.
This software will help students learn standards-based mathematics as they simulate the original artifacts, and develop their own creations.

This site contains java applets that are designed to help students visualize important concepts in mathematics and physics.

The Connected Curriculum Project
Interactive learning environments for a wide range of mathematics and mathematically-based applications.  Areas of application are biology, chemistry, economics, engineering, environmental sciences, epidemiology, and physics. 


Virtual Lab in Probability and Statistics
The site is divided into chapters grouped into topics such as probability, statistics and special models, including Bernoulli Trials.

Visualization of Statistical Concepts Math/Trig/Prob
This site features applets designed to help students more easily visualize and understand abstract statistics concepts through interactive computer-aided instruction.

Physics and Astronomy

Applets for Quantum Mechanics
The illustrations of quantum systems at this site promotes visual and conceptual learning, important due to the non-intuitive nature of the subject, gives modern applications and advanced topical links.
