Students become online authors in this lesson in which they write and post a short story using wiki technology.

Students and the teacher produce a class book through a group-writing activity, focusing on a basic before-during-after sequence of events.

Students hone their teamwork skills and play off each other's writing strengths as they participate in prewriting activities for a story to be written collaboratively by the whole class.

Using a collaborative story written by students, the teacher leads a shared-revising activity to help students consider content when revising, with students participating in the marking of text revisions.

As a continuation of the theme of potential and kinetic energy, this lesson introduces the concepts of momentum, elastic and inelastic collisions. Many sports and games, such as baseball and ping-pong, illustrate the ideas of momentum and collisions. Students explore these concepts by bouncing assorted balls on different surfaces and calculating the momentum for each ball.

In this lesson, student groups create a short, simple play based on their study of broadsides written just before the American Revolution. By analyzing the attitudes and political positions are revealed in the broadsides, students learn about the sequence of events that led to the Revolution

Drawing on the resources of the Library of Congress's Printed Ephemera Collection, this lesson helps students experience the news as the colonists heard it: by means of broadsides, notices written on disposable, single sheets of paper that addressed virtually every aspect of the American Revolution.

When European colonists came to North America, they faced the challenge of establishing societies that reflected their identity and mission for God. Experiments with economic and civil liberty followed in the name of the common good. Colonists and, later, the Founding generation became convinced that legally requiring individuals to commit their labor or their money towards a communal farm or church, with no regard for individual contribution or conscience, violated principles of justice.

This lesson focuses on John Winthrop's historic "Model of Christian Charity" sermon which is often referred to by its"City on a Hill" metaphor. Through a close reading of this admittedly difficult text, students will learn how it illuminates the beliefs, goals, and programs of the Puritans. The sermon sought to inspire and to motivate the Puritans by pointing out the distance they had to travel between an ideal community and their real-world situation.

Using different writing/drawing materials (e.g., markers, color pencils, pastels, etc.), students learn how to communicate different moods and/or feelings to support their written ideas and how authors do the same through their work.

Students use their five senses as a prewriting tool to guide their poetry writing as they compose free-form poems using imagery to describe a color.

This activity provides an introduction to natural selection and the role of genetic variation by asking students to analyze illustrations of rock pocket mouse populations (dark/light fur) on different color substrates in the Sonoran Desert (light/dark) over time. Based on this evidence, and what they learn about variation and natural selection in the accompanying short film, students use this evidence to explain the change in the rock pocket mouse populations on the lava flow (dark substrate) over time. This is one of several classroom activities, focusing on related topics and varying in complexity, built around the short film. This ten minute film shows adaptive changes in rock pocket mouse populations, demonstrating the process of natural selection and can be accessed at http://www.hhmi.org/biointeractive/making-fittest-natural-selection-and-adaptation. The film is also available as an interactive video with embedded questions, which test students’ understanding as they watch the film.

In this lesson art and music activities help students express and understand their feelings.

Pat Mora's poem "Echoes" demonstrates that our senses are powerful tools for literary analysis and comprehension as students use their senses to discover new ways to read and write.

This classroom activity for high school students uses a collection of Hubble Space Telescope images of galaxies in the Coma Cluster. Students study galaxy classification and the evolution of galaxies in dense clustered environments.

Students learn that what you read in books can really add up when they analyze literary texts for economic concepts.

Have you ever wondered why it takes such a long period of time for NASA to build space exploration equipment? What is involved in manufacturing and building a rover for the Red Planet? During this lesson, students will discover the journey that a Mars rover embarks upon after being designed by engineers and before being prepared for launch. Students will investigate the fabrication techniques, tolerance concepts, assembly and field-testing associated with a Mars exploratory rover.

Multidimensional, challenging, and popular with students, comics provide an excellent way to introduce the concept of genres.

This lesson uses comic strip frames to define plot and reinforce the structure that underlies a narrative. Students finish by writing their own original narratives.
