Coniferous forests are found mainly within the Northern Hemisphere. These forests are made up of mainly cone-bearing trees such as pines, firs and spruces. Learn why their needles seem to keep the forests green all year long. Study the kinds of creatures that inhabit this environment such as the moose, the brown bear and different types of deer.
The study of rocks is an essential part of studying the age and evolution of the Earth. In Rocks, students will examine the characteristics of each of the major types of rocks: igneous, sedimentary and metamorphic. From stalactites and stalagmites to intrusive and extrusive rocks, students will examine how rocks are formed in this exciting program. A visit to Mammoth Mountain in California showcases the interesting rock formation known as the Obsidian Dome
The Earth is filled with a diverse variety of land formations - from mountains to valleys, canyons to plains. But what's the difference between a folded and a block mountain? A mesa and a butte? A bay and a peninsula? In Land Formations, students learn the answers to these and other questions as they examine how forces such as weathering and continental drift have impacted the rise and fall of land on the Earth.
The geological history of the Earth covers billions of years! In Geological History, students will examine a time line of the Earth, tracking its violent beginnings and ever-changing face. Discover the four major segments of geologic time (the Precambrian and the Paleozoic, Mesozoic and Cenozoic eras), and learn about the plant and animal life that developed during each. A journey under the sea shows how geologists study the layers of rock that lie deep under the ocean floor...
The universe is limitless! It contains stars, solar systems, galaxies, black holes and much more. Universe looks at these wonders-all incredible, all unique and all just a small part of a larger entity. Students will explore some big questions about the universe, including: How was it formed? How big is it? How can we explore the far reaches of the universe? They’ll learn about light years and the electromagnetic spectrum and take a close-up look at a gamma ray telescope. A fun, hands-on activity will demonstrate why it seems so dark in space
