Mantle Motions

Young scientists piece together the geological puzzle that is the earth in the third and final lesson of this earth science series. With the help of numerous multimedia resources and a series of engaging hands-on activities, learners...

Do you prefer your cookies with transform plate boundaries or divergent plate boundaries? Learn about fault lines and plate tectonics with an informative and delicious hands-on activity. Using a cookie to represent the earth's...

Students explore geology by completing a science worksheet in class. In this tectonic plate lesson, students discuss how the Earth's plates move and what the impact of this movement often becomes. Students define the different layers and...

Give science learners nine questions about the biogeography of hydrothermal vents and turn them loose to research this fascinating habitat. Working in cooperative groups, they prepare a report that addresses each of the questions. A...

Students build and test structures that can best withstand earthquakes. They create their structures from playdough, cornstarch, grape-nuts and popsicle sticks and place their structures on a "shake table."

The tectonic processes that have resulted in the formation of the Marianas Arc, and the Marianas Trench are explored. Groups of pupils access websites that give them a wealth of information about these formations. Each group must prepare...

There are few natural phenomena as startling as an earthquake, and depending on the building you're in, these experiences can be downright terrifying. Follow along as this video explores the factors that determine how a building reacts...

Learners identify the three layers of the earth: core, mantle and crust. They demonstrate knowledge of the concepts of convergent and divergent motions of the earth and an understanding of plate tectonics.

Students locate some of the 1,500 active volcanoes on a world map. Then by comparing their maps with a map of the world's tectonic plates, they discover that volcanoes occur because of the dynamic nature of the Earth's lithosphere.
