In this illustrated tutorial, students will see a specific method for constructing ray diagrams for double concave lenses.

This lesson explains in detail the Convergence and Divergence of Improper Integrals. Includes many formulas and examples.

This lesson explains what lenses are, the different between a converging and diverging lens, the difference between a double convex and double concave lens, and gives definitions for terms related to lenses.

Here is a summary of convergence tests. They are listed in the order that you should use/try them when testing for convergence or divergence.

This lesson discusses the limit of a sequence in mathematics. Compares convergent and divergent sequences and presents numerical and graphical examples.

A simulation that demonstrates divergent plate boundaries and seafloor spreading. A focus is on evidence of the Earth's normal and reversed polarity over geologic time in the rock record.

This interactive activity adapted from NASA features world maps that identify different sections of the Earth's crust called tectonic plates. The locations of different types of plate boundaries are also identified, including convergent,...

This site gives an example of an alternating series whose terms go to zero but whose sum diverges. Can you guess why it diverges? Go to this site to find out why.

This site expresses Stokes Theorem: the relationship between curl, gradient, and divergence theorem. Includes references and links to further information.

This page gives a brief statement of the Integral Test for convergent or divergent series. This test is also called the Cauchy Integral Test or the Maclaurin Integral Test.

This resource defines the Harmonic Series and gives a proof of its divergence.

This page gives a great overview of series in mathematics, including a definition of convergence and divergence. Provides links to more information about specific types of series.

An article in which Jamie McKenzie states his belief that each district should create a Questioning Toolkit which contains several dozen kinds of questions and questioning tools. Portions of the Questioning Toolkit should be introduced...

The resource examines surface integrals. Topics investigated are parametric surfaces, surface integrals, Stokes? theorem, and the divergence theorem. Class notes, definitions, and examples with detailed solutions are included. The notes...

Animated simulations showing the three types of plate movements: divergent, convergent, and lateral plate boundaries.

The definition of a series is provided in a PDF document. The document also details the geometric, telescoping and harmonic series, tests for divergence, and series rules.

Students use this tutorial to investigate the refractive ability of converging and diverging lenses.

Determine the location of the image in this interactive simulation of a lens and mirror optics bench. Both converging and diverging lenses and mirrors are included.

Kids learn about lenses and light in the science of physics including concave, convex, converging, diverging, focal point, meniscus, and Plano lenses.

Using your computer mouse you can simulate transforming, collisional, divergent and convergent plate boundaries. Descriptions of each plate boundary are also available.

In this article from 2004, UC Berkeley reports that additional fossils have been found from the 2001 discovery of Ardipithecus kadabba. This find holds great importance because it is suggested that it may represent the first species...

Learning Activity on the divergent views of African American leaders. Students review and compare the competing visions of Booker T. Washington, Marcus Garvey and W.E.B. Du Bois. In addition, students choose a contemporary African...

Interactive two-day lesson plan that engages students in consideration of divergent policy alternatives concerning how the situation in Iraq should be handled, who should be in charge, and what the goals should be.

Interactive lesson plan places young scholars in the role of decision-makers as they explore divergent policy alternatives concerning how the post-war period in Iraq should be handled, who should be in charge, and what the goals should be.
