A demonstration of the distributive property of multiplication using models. This video is less than 15 minutes.

The lessons posted on this site were designed to engage students with real-world data relevant to content taught in middle school and high school science courses, and to foster an understanding of ways in which they might gather organize, analyze and interpret the data in order to draw scientifically valid inferences, interpretations and conclusions. Most of the labs use computer-based technology of spreadsheet programs or the Python programming interface. The Python lessons guide students in computational thinking to create simple programs to manipulate data. The lessons also provide students (and teachers) with instructions and guidance in the use of these technologies. Teacher and Student worksheets, as well as any supporting files, are linked to from links at the top of each lesson webpage as well as from the downloads page ("downloads" link on the scrolling menu to the left).

The electromagnetic spectrum* describes the range of energies associated with different forms of electromagnetic radiation. Electromagnetic radiation travels through space as discrete packets called photons. Photons can transport energy the way particles do, but photons have no mass*. Photons vary in the amount of energy they carry. The energy associated with a photon determines where on the electromagnetic spectrum it falls.

The Washington Post presents articles related to the World Food Crisis. The articles date from 2008-2009 and are not updated.

This is an instructional video demonstrating how to plot data to create a scatterplot and then find the correlation and equation of the line of best fit.

This course outline examines topics of importance to educators participating in instructional design projects. Topics include needs assessment, adult learning principles, learning objectives, instructional strategies, assessment, implementation and evaluation. Learners will develop a course using media and open educational resources while observing copyright and plagiarism guidelines.

The series of knitting lessons that follow can be adapted for students from about third or fourth grade all the way through high school, and will fully engage students of widely varying abilities.

The "quantum" of economics is the optimizing individual. All of economics ultimately boils down to the behavior of such individuals. Microeconomics studies their basic actions and interactions: individual markets, supply and demand, the impact of taxes, monopoly, etc. Macroeconomics then lumps together these individual markets to study national and international issues. In structure this book—which covers only microeconomics—is not unlike a hiking trip. We start out by putting our boots on and getting our gear together: in Part I we study the optimizing individual. Then we set out on our path and immediately find ourselves hacking through some pretty thick jungle: even simple interactions between just two people (Part II) can be very complicated! As we add even more people (in studying auctions, for example), things get even more complicated, and the jungle gets even thicker. Then a miracle occurs: we add even more people, and a complex situation suddenly becomes simple. After hacking through thick jungle, we find ourselves in a beautiful clearing: competitive markets (Part III) are remarkably easy to analyze and understand.
