In this lesson, students learn about work as defined by physical science and see that work is made easier through the use of simple machines. Already encountering simple machines everyday, students will be alerted to their widespread uses in everyday life. This lesson serves as the starting point for the Simple Machines Unit.

This is a very comprehensive site, a complete collection of Marvell's works and several critical essays, in additon to biographical material.

A short animated video demonstrating a few common simple and compound machines used doing yard work. [2:00]

What happens when the ground under your feet is ice and it's moving? This video segment adapted from NOVA features some of the dangers faced by scientists conducting research in Antarctica.

In this video [25:55] learn about many ways to combine art and science as we observe the world around us. We often think of scientists as methodical and precise, and artists as free-willed, impulsive creators. But did you know that some art has science packed right into it? And that artists throughout history have helped scientists conduct their work? Learn about the photography of Berenice Abbott who documented the changing New York skyline with photographs of architecture and urban design of the 1930s, and science interpretation in the 1940s to 1960s. Learn how to use the sun to air dry your salt dough creations and explore papier-mache.

Students learn how forces are used in the creation of art. They come to understand that it is not just bridge and airplane designers who are concerned about how forces interact with objects, but artists as well. As "paper engineers," students create their own mobiles and pop-up books, and identify and use the forces (air currents, gravity, hand movement) acting upon them.

What kind of unit conversion would you like to do? This site will allow you to do a multitude of conversions. Just click on the specific measurement you are needing to convert. It also provides a history of measurements and a chart of metric symbols.

Bartleby provides the full text for the following poems: "The Retreat", "Peace", "The Timber", and "Friends Departed".

Mr. Andersen defines the terms energy, work, and power. He also uses a simple example to calculate both work and power. [3:34]

In the following video Paul Andersen explains how conservative forces can be used to store potential energy in an object or a system. The work done is equal to the amount of potential energy in the object. The following conservative forces are described; gravitational, spring and electric force. [6:39]

In the following video Paul Andersen explains how the kinetic energy gained by an object is equivalent to the work done on the object. The force on the object must act parallel or antiparallel to the motion of the object to do work. [8:12]

In the following video Paul Andersen explains how the mechanical energy added or removed from a system results from work. For work to occur a force must act parallel to the displacement of the system. Since work and energy are equivalent the work-energy theorem allows of for calculating the work as the change in kinetic energy. [7:01]

Example of calculating energy using the First Law of Thermodynamics. [7:14]

Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.

It's a mathematician's dream come true. An easy trick for checking mathematical computations, without a calculator! Believe it or not, it works with all four operations.

A basic guide concerning how to go about publishing your writing. Includes information about what it means to be published, publication types, and guidelines for submission. CCSS.ELA-Literacy.CCRA.W.6

This site is from the Physics Department at Georgia State University. The conservation of energy as a fundamental conservation law is presented and compared to other conservation laws (momentum and angular momentum). Links to further information are provided.

Learn about Keller's large donation and letter of support for the National Association for the Advancement of Colored People (NAACP) in 1916. Through video, discussion questions, teaching tips, Keller's original letter to the NAACP, and vocabulary, students explore what it means to be an anti-racism activist in the Jim Crow era.[1:38]

Contains full text of "Donne's Relation to Petrarch," as appears in "The Cambridge History of English and American Literature." Explains how Donne broke the Petrarchian poetic style.

This is an e-text of the first published selection of the poems of Emily Dickinson (1830?1886) originally appeared in 1890, edited by Mabel Loomis Todd and Thomas Wentworth Higginson. The text contains 115 poems and can be searched by first lines. It contains such familiar poems as "Because I could not stop for Death," and "I never saw a moor," as well as many less well-known works such as "That short, potential stir," or one of her longer poems, "To know just how he suffered would be dear."

Although Disney's version of Cinderella is most popular in America, hundreds of versions exist across many cultures. This resource provides lessons, which examine the similarities and differences in literary elements among many versions of this fairy tale.
