This video describes how global communication has evolved throughout history, from the printing press to the internet.

In this interactive, students use logic and mathematical skill to place aquatic animals at locations on a Cartesian graph with cardinal directions. Then, they determine both the vertical and horizontal distances between points. The riddles in the interactive, including one that requires an understanding of rate, have randomized values so that students can practice placing points at different locations and calculating different distances. The accompanying classroom activity provides a review of concepts related to determining the distances between points on a Cartesian graph and a response sheet to help students work with the interactive

In this lesson, students will estimate capacity and the relationship between several unusally shaped containers. They will verify relationships, express the relationship using variables, and apply the expressions to determine equivalent portions for each standard unit.

In this online activity, students review both sides of the "clean coal" issue by reading transcript excerpts from a debate between Joe Lucas, vice president of the American Coalition for Clean Coal Electricity and David Roberts, a senior writer for the environmental news blog Grist.

In this lesson, students learn more about the work of the United Nations by researching an issue they care about. The second objective is for students to understand the importance of their voice in the world and how to use social media responsibly in order to share their knowledge with the wider community.

In this lesson students explore both the passion that inspired Picasso to take political action and the thought process behind the work. Students will reflect on their own decision making process when they feel compelled to take public action. This lesson will lead students to investigate the following Life-Long Learning Question: How does passion inspire public action?

This lesson is intended to be used with the PBS FRONTLINE documentary "League of Denial" and supports students learning by contextualizing the concussion crisis in the NFL with background on concussions in youth.

This lesson offers a series of activities that allow students to explore and interact with poetry by writing letters to poets.

Students will compare the experience of listening to a piece of music (without video or other visual accompaniment) and the experience of watching a performer as the piece is played.

In this interactive, students use clues and logic to plot the location of aquatic animals on a Cartesian graph that represents the four cardinal directions. The three riddles in the interactive, including one that requires students to understand rate, have randomized values so that students can practice placing points at different locations on the graph. The accompanying classroom activity provides students with a review of locating points on a Cartesian graph. A response sheet helps students work with the interactive.

In this interactive, use logic to solve three riddles involving a jumping wallaby competition. Then, using knowledge of inequalities and rational numbers, place the wallabies on the correct range from –5 to 5 on the number line. Numbers are randomized so that the range on the number line is different each time the riddles appear. The accompanying classroom activity includes a concept review and response sheets to support the online work.

In this interactive, use logic to solve riddles involving a wallaby jumping contest. Then, place each contestant’s jump—a fraction, mixed number, or decimal between –5 and +5—at the correct point on the number line. Backward jumps are represented by negative numbers and forward jumps by positive numbers. Numbers are randomized so that riddles can be solved and wallabies placed on the number line multiple times. The accompanying classroom activity includes a fraction/decimal concept review and a response sheet to accompany the online work.

In this interactive, learn about wildfires in the western US using an interactive map profiling active fires and graphs depicting historical data. In the accompanying classroom activity, students review aggregated data for 11 western states and then focus on data from a single state, describing the shape of the data and comparing changes across decades. To get the most out of this activity, students should be comfortable calculating mean and be familiar with percent.

In this interactive, students explore the Bay Area's major public transit lines and the dramatic income disparities that exist among the communities living along those routes in this infographic from KQED. In the accompanying classroom activity, students interpret the data and calculate the mean, median, and range for a given transit line.

Students develop and present an evidence-based argument about a change they would like to bring about at their school to make it a healthier place for all students. In this interactive lesson designed for both full-class and individual or small-group work, students examine a similar effort, chronicled in BASIC BLACK: Youth Fighting Fat, in which a group of concerned Boston teens seeks to address the problem of obesity in their community.

At the time of the U.S.-Mexican War (and the height of the popularity of Manifest Destiny), there were some Americans who spoke out against what they regarded as a war of aggression. However, for the most part, the American public supported the war and the idea of Manifest Destiny itself. Today many historians see things differently. Historian David Pletcher writes of the U.S.-Mexican War: "This war was an aggressive war in which we attacked a neighbor and however much we won from the war, we do not like to look at the way in which we won it." Pletcher's idea may be borne out by the following two facts: there is still not a federally-funded memorial to those who fought in the U.S.-Mexican War and this war is so little studied and known about in the United States. In this activity, students will explore different American opinions about the U.S.-Mexican War (and by extension, Manifest Destiny) from both the 19th century and today. Students will then apply their knowledge by having a debate on the topic.

In this lesson, students will explore the adventures of these three world travelers. After viewing three short videos about their journeys, students will analyze photographs of a city that all three travelers visited, write a log entry describing a sighting of Zheng He’s fleet of ships, and then read excerpts from Marco Polo’s and Ibn Battuta’s accounts of their journeys. The lesson will conclude with students writing a short play in which the three travelers meet and share stories of their adventures.

In this lesson, students represent numbers in scientific notation, and use geometry to solve problems related to three-dimensional figures. They will also explore distance and capacity problems about planets in the solar system.

In this professional development video, teachers can focus on the topic of creating equivalent fractions that represent one-half through the use of geoblocks. This video can be used in conjunction with the To Half or Half Not Lesson Plan.

Learn how weather is the combination of four factors—temperature, wind, precipitation, and sunlight and clouds—that occur at a given place and time in this lesson plan from WGBH. The mix of factors is changing all the time; therefore, weather conditions are changing all the time. Students can observe the four factors in various types of weather and identify evidence of weather factors in different weather conditions.

This resource was developed through WGBH’s Bringing the Universe to America’s Classrooms project, in collaboration with NASA.
