Slow Flowing Solids Explain Tectonic Plate Movement View Video
On the Big Island of Hawaii, lava from volcanoes forms new rock. Physical and chemical processes contribute to the weathering of rock into sediment and soil. View Video
The solar system started to form when clouds of dust and gas collapsed, under the force of gravity, into a flat, spinning disk. View Video
The opening of the Atlantic Ocean between two tectonic plates at a spreading ridge separated the two continents. View Video
Spreading ridge volcanoes form in the deep sea where two plates are moving apart. View Video
Students explore properties of addition using both real dominos and dominos that they make out of paper. Both 3-D and 2-D tools provide concrete representations of the lesson's mathematical ideas. View Video
In this project, students work to build and stain wooden pencil boxes. This involves selecting the right tools to measure and calculate the surface area of geometric shapes. View Video
First-graders solve real-world measurement problems using standard and non-standard measuring tools. View Video
In this lesson, students use array structures to reason and conjecture about relationships between sums and products. View Video
Subduction zones are where rock slides under less-dense rock. Magma, enriched with highly pressurized steam and CO2, rises to the surface under subduction boundaries, making volcanoes. View Video
Scientists have proposed that the Moon was formed from a collision in the early solar system. View Video
Scientists Chuck Blay and Dave Sherrod compare Hawaiian volcanoes to Mt. Saint Helens. View Video
