The purpose of this task is to have students think about the meaning of multiplying a number by a fraction, and to use this understanding of fraction multiplication to make sense of the commutative property of multiplication in the case of fractions.

Students explore the connotations of the colors associated with the characters in F. Scott Fitzgerald's "The Great Gatsby."

Students will learn about issues concerning soil and water and how farmers use science to help conserve these resources.

Viviana rides along with a conservation officer, who protects the environment and natural resources. Dealing with wildlife, hunting and angling issues and pollution, he investigates possible violations. A grateful public is his key reward

Find out what work is like for a conservation officer in Canada. This work description is applicable to all Conservation and fishery officers (NOC 22113).

Hank wraps up the Crash Course on ecology by taking a look at the growing fields of conservation biology and restoration ecology, which use all the kung fu moves we've learned about in the past eleven weeks and apply them to protecting ecosystems and to cleaning up the messes that we've already made.

La ressource consiste en une fiche pédagogique portant sur une expérience d'électrostatique. Celle-ci propose des informations pratiques pour l'enseignant ainsi qu'une explication pédagogique de l'expérience. La ressource contient également une capsule vidéo.

A list of things you should consider when planning for your students, including: learner profiles, elements of PeBL, curricular expectations, strategies, communications, assessments.

Students are introduced to the idea of improving efficiency by examining a setting that is familiar to many teenagers fast food restaurants. More specifically, they learn about the concepts of trade-offs, constraints, increasing efficiency and systems thinking. They consider how to improve efficiency in a struggling restaurant through delegating tasks, restructuring employee responsibilities and revising a floor plan, all while working within limitations and requirements. Finally, students summarize and defend their suggested changes in argumentative essays.

"Even though vaping is less harmful than smoking, there are still consequences for you to consider. Vaping can expose you to chemicals that could harm your health. We’re here to give you the facts about vaping so you can make informed choices about your life."

This art history video discussion examines John Constable"s "The Hay Wain", 1821. Oil on canvas, 51 1/4" x 73" (130.2 x 185.4 cm) (The National Gallery, London).

In this transcript of an interview for Eyes on the Prize, Justice Constance Baker Motley recalls her role as an NAACP attorney in landmark school desegregation cases.

This is an activity about identifying constellations. Learners will look for constellations in the Sky Tonight online program, draw images of these constellations, and attempt to find them in the night sky. Learners will also be asked to make connections between the shape of a constellation and its namesake. This activity requires the use of a computer with Internet access. It also requires access to the clear night sky. This activity is Sky Tonight Activity 1 in a larger resource, Space Update.

Students use simple household materials, such as PVC piping and compact mirrors, to construct models of laser-based security systems. The protected object (a "mummified troll" or another treasure of your choosing) is placed "on display" in the center of the modeled room and protected by a laser system that utilizes a laser beam reflected off mirrors to trigger a light trip sensor with alarm.

Using Construct-a-Word, students learn letter-sound correspondence by combining a beginning letter or blend to a word ending to create words.

We design and create objects to make our lives easier and more comfortable. The houses in which we live are excellent examples of this. Depending on your local climate, the features of your house have been designed to satisfy your particular environmental needs: protection from hot, cold, windy and/or rainy weather. In this activity, students design and build model houses, then test them against various climate elements, and then re-design and improve them. Using books, websites and photos, students learn about the different types of roofs found on various houses in different environments throughout the world.

An interactive applet and associated web page that provide step-by-step animated instructions on how to construct a triangle given all three sides (SSS), using only a compass and straightedge. The animation can be run either continuously like a video, or single stepped to allow classroom discussion and thought between steps. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.
