Young geologists piece together the puzzle of plate tectonics in an earth science lesson. Given a physical map of the world, they search for land formations that indicate the location of different types of plate boundaries.

Every living creature can leave a fossil record, yet most fossils belong to extinct organisms rather than ones currently living. Scholars learn about dating rock layers, fossils, and the environment of the past. Pupils understand that...

Young geologists get a glimpse beneath the earth's surface in this plate tectonics investigation. After first learning about the different layers of the earth and the constant movement of its plates, young...

Now that you know the ocean has layers, let's name them. The seventh installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program covers terminology associated with ocean layers, such as thermocline and...

Mid-ocean ridges, rift valleys, island arcs, mountain ranges, earthquakes, volcanoes ... there are so many features associated with plate tectonics. The 14th installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography...

Air, air, everywhere, but what's in it, and what makes Earth's air so unique and special? Journey through the layers above us to uncover our atmosphere's composition and how it works to make life possible below. Pupils conduct...

Here's a topic classes can really dig—the fossil record. Use the well-organized and thoughtful road map to take eighth graders back in time to unearth the answer. Learn how our climate has changed, and how organisms have...

After reading s short description of the Grand Canyon, readers demonstrate their ability to use context to determine the meaning of words in the passage.
