4434Population Modeling Applet
http://www.merlot.org/merlot/viewMaterial.htm?id=314085
In this applet, the user applies Euler's Method to modeling population growth using the Malthus exponential model and the Verhulst constrained growth model. After finding the Euler solution, the user can check the solution with the Adaptive Euler Approximation or with a slope field. Also, the user can enter an exact solution obtained from separating variables (or whatever) and again check the Euler solution graphically.Old Egyptian Fractions
http://www.merlot.org/merlot/viewMaterial.htm?id=720775
Old Egyptian Fractions at MathCats(Web and android version)Old Egyptian Math Cats knew fractions like 1/2 or 1/4 (one piece of a pie).But to make fractions like 3/4, they had to add pieces of pies like 1/2 + 1/4 = 3/4.Old Egyptian Math cats never repeated the same fraction when adding.They never wrote: 1/4 + 1/4 + 1/4 = 3/4How it works:Choose puzzles from the list on the top. ( * = easier, **** = very hard.)Add 2 or 3 fraction pieces below.After you find one solution, the puzzle is marked "Solved." Can you find more solutions? (Click to see them listed on the bottom.)There's the android version in the mirror site linkCyberkidz educational games

http://www.merlot.org/merlot/viewMaterial.htm?id=845084
More than a hundred scientific societies, universities, research institutes, and organizations all over the world have banded together to dedicate 2013 as a special year for the Mathematics of Planet Earth.Our planet is the setting for dynamic processes of all sorts, including the geophysical processes in the mantle, the continents, and the oceans, the atmospheric processes that determine our weather and climates, the biological processes involving living species and their interactions, and the human processes of finance, agriculture, water, transportation, and energy. The challenges facing our planet and our civilization are multidisciplinary and multifaceted, and the mathematical sciences play a central role in the scientific effort to understand and to deal with these challenges.Matlab-based Numerical Methods in Engineering course

Measuring Biodiversity across North America
http://www.merlot.org/merlot/viewMaterial.htm?id=332699
Through this series on measuring biodiversity students will conduct investigations based on their own questioning, they will develop a methodology, collect and analyze data, test hypotheses, and communicate results. Each example given is a model for analysis with step-by-step procedures for investigating categories of questions on biodiversity and the inherent value of the different landscapes of North America.Goals: As a result of completing an investigation into the biodiversity of North American Mammals, all students should develop an understanding of the following. The concept of biodiversity, and ways to measure the diversity of organisms The role of taxonomy in assessing biodiversity Associations between the distribution of organisms and environments How to plan and conduct an investigationIn addition, students should become more familiar with the mammal communities and ecoregions in their residential areas, the biomes and ecoregions across North America, and practice independent inquiry about the natural world.Pi Day
http://www.merlot.org/merlot/viewMaterial.htm?id=999301
This is a librarian designed research tool to help people learn about what Pi is and why we should celebrate Pi Day (3.14.15). Includes a video with everything you wanted to know about Pi in 3.14 minutes.12.S990 Quantifying Uncertainty (MIT)
http://www.merlot.org/merlot/viewMaterial.htm?id=884089
The ability to quantify the uncertainty in our models of nature is fundamental to many inference problems in Science and Engineering. In this course, we study advanced methods to represent, sample, update and propagate uncertainty. This is a "hands on" course: Methodology will be coupled with applications. The course will include lectures, invited talks, discussions, reviews and projects and will meet once a week to discuss a method and its applications.
