This 27-minute video lesson is part 1 of Sal's overview of the Haitian Revolution. It covers the slaves rebellion in Saint-Domingue (Haiti) and the rise of Toussaint. L'Ouverture. [History playlist: Lesson 18 of 26]

This 17-minute video lesson concludes Sal's overview of the Haitian Revolution. It covers Dessalines taking on Leclerc and Rochambeau. [History playlist: Lesson 19 of 26]

Students practice their multiplication skills using robots with wheels built from LEGO® MINDSTORMS® NXT kits. They brainstorm distance travelled by the robots without physically measuring distance and then apply their math skills to correctly calculate the distance and compare their guesses with physical measurements. Through this activity, students estimate parameters other than by physically measuring them, practice multiplication, develop measuring skills, and use their creativity to come up with successful solutions.

This collection uses primary sources to explore leaders of Latin American revolutions. Digital Public Library of America Primary Source Sets are designed to help students develop their critical thinking skills and draw diverse material from libraries, archives, and museums across the United States. Each set includes an overview, ten to fifteen primary sources, links to related resources, and a teaching guide. These sets were created and reviewed by the teachers on the DPLA's Education Advisory Committee.

Why does the Moon not always look the same to us? Sometimes it is a big, bright, circle, but, other times, it is only a tiny sliver, if we can see it at all. The different shapes and sizes of the slivers of the Moon are referred to as its phases, and they change periodically over the course of a lunar month, which is twenty-eight days long. The phases are caused by the relative positions of the Earth, Sun, and Moon at different times during the month.

Students work in teams of two to discover the relative positions of the Earth, Sun and Moon that produce the different phases of the Moon. Groups are each given a Styrofoam ball that they attach to a pencil so that it looks like a lollipop. In this acting-out model exercise, this ball on a stick represents the Moon, the students represent the Earth and a hanging lightbulb serves as the Sun. Students move the "Moon" around them to discover the different phases. They fill in the position of the Moon and its corresponding phase in a worksheet.

Video Description:  What causes the phases of the Moon? From New Moon to Full Moon, the Earth-Sun-Moon system is responsible for the Moon’s changing phases. Learn more about rotation, revolution and this repeatable pattern. Video Length:  3:13. NASA eClipsTM is a suite of online student-centered, standards-based resources that support instruction by increasing STEM literacy in formal and nonformal settings.  These free digital and downloadable resources inform and engage students through NASA-inspired, real-world connections.NASA eClips Our World videos (grades 3-5) help students understand the differences between science (the natural world) and engineering (the designed world).  These video segments supplement elementary learning objectives not only in science, technology, engineering and mathematics, but also in reading, writing, visual and performing arts.

Students learn the concept of angular momentum and its correlation to mass, velocity and radius. They experiment with rotation and an object's mass distribution. In an associated literacy activity, students use basic methods of comparative mythology to consider why spinning and weaving are common motifs in creation myths and folktales.

Did you know that you would be a different age if you lived on Mars? It's true! In this activity, you'll learn about the different rotation and revolution periods of each of the planets and calculate your age respectively. Included is an astronomy history lesson and explanation of Kepler's Laws of Orbital Motion. The activity has a calculator built into the web page, but the activity can be made more math intensive by using the given data to calculate the learner's age by hand.
