Volcanoes are one of Earth's most fascinating and destructive forces. In Volcanoes, students will get an up-close look at these fiery formations, discovering how they form and what causes them to erupt. Learn the difference between magma and lava, and discover the characteristics that enable volcanologists to classify a volcano as cinder cone, shield or composite. Examine the anatomy of an active volcano, and learn about historical eruptions that have left a mark on our planet. A fun, hands-on investigation demonstrates how a tilt meter is used to predict when a volcano might erupt by charting changes in the slope of the surrounding ground, while a visit to Horseshoe Lake at Mammoth Mountain, California, highlights an invisible sign of volcanic activity -- poisonous carbon dioxide fumes. Part of the Earth Science in Action DVD Series. A teacher's guide is available online. 23 minutes. Grades 5 to 8.

Water is vital to all life on Earth and covers nearly three-fourths of our planet's surface. Where does it come from? Will we use it up eventually? In The Water Cycle, students learn that Earth has the same water supply today as it did millions of years ago. Examine the amazing process by which water is continually recycled and transported from place to place through evaporation, condensation and precipitation. Also find out how energy from the sun drives the water cycle and how the atmosphere prevents water from slipping away from Earth. A fun, hands-on investigation demonstrates how an artesian well works, while a visit to a desalination plant showcases how salt water is purified. Part of the Earth Science in Action DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.

The rocks and soil that make up Earth's surface are constantly being affected by a variety of forces, ranging from heat and frost to water and wind. In Weathering and Erosion, students will discover the natural forces that cause weathering, erosion and deposition, and see the many effects that these processes have on Earth's surface. Students will examine natural structures around the world and see how weathering and erosion have affected them, while discovering ways in which people have become better prepared to battle these forces through conservation. In addition, a fun, hands-on experiment demonstrates how running water erodes different types of soil. Part of the Earth Science in Action DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.
Hanging metric weights used to extend scale capacity of Ohaus 750-S0 and 750-SW metric triple-beam balances (not included). Cast iron construction has durability and long life. The set of three attachment weights includes two 1,000g weights and one 500g weight.
Calibration weights are used to measure the weight or mass of an object using a balance or scale, or to calibrate other weights or instruments. Calibration weights can be certified or uncertified. Certified weights meet strict guidelines for accuracy and can usually be recertified. Certified weights are used in labs where a high degree of accuracy and repeatability is required. Uncertified weights are used where a lower degree of accuracy is required, including student laboratories, rough weighting operations, and measuring force. Hooked and slotted weights are often used to measure pressure, torque, and tensile strength, and to demonstrate basic laws of physics. Calibration weights differ from lab weights, which are general purpose weights used to hold an object in place, similar to a paperweight.
