Non-nutrient agar powder is typically used in classrooms for microbiology experiments, such as studying slime molds, observing fungal growth, or culturing environmental samples. Since it lacks nutrients, it does not support the growth of most bacteria or fungi on its own, making it ideal for experiments where a nutrient source is added selectively to encourage the growth of specific organisms. It's often used to highlight the effects of environmental factors on microbial growth, demonstrate the role of external nutrient sources, or as a base for investigating other biological processes.
This parameter is important in determination of the corrosive properties of water, caused by carbonates, bicarbonates as well as dissolved salts. Testing alkalinity is important in the treatment of drinking water, waste water, swimming pools, heating and cooling systems, food and beverage systems, and soil and environmental testing, as well as in agriculture, farming and fish farming. Includes 110 tests.
Winter, spring, summer and fall. We know what happens in our own backyards at these times during the year, but it isn't the same everywhere in the world! When it's warm and sunny where you are, it might be very different in other places of the world. Why do the seasons change? And what causes different regions in the world to have different climates? These and other questions are answered in All About Climate & Seasons, where young students will learn about these yearly changes through engaging examples and explanations. A hands-on investigation shows the effects of direct sunlight on areas of the world, while Dr. Jon Nese, chief meteorologist at The Franklin Institute Science Museum in Philadelphia, demonstrates the concept behind the device known as an orrery. Part of the multivolume Weather for Children DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades K to 4.
Over the course of its 4.5 billion-year history, Earth has undergone a great number of changes -- from a red-hot ball of molten lava to a planet with an environment capable of sustaining life. In All About Earth's History, children will trace the evolution of Earth and the organisms that populate it. Young viewers will take a peek deep inside the Earth, examining its varied layers while discussing how scientists use fossils to help map out the complex time line of events that has changed Earth over millions of years. A visit to the Grand Canyon examines the rock layers of this famous land formation, revealing how the climate of the region has changed over time. A lively, hands-on activity demonstrates how scientists use core samples to study the Earth. Part of the Earth Science for Children DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades K to 4.
They shake the ground underfoot, causing tremors that, at their worst, can leave cracks in highways and topple buildings. But for the most part, earthquakes are constantly rumbling through the Earth with a force that's barely detectable. But why do they occur? In All About Earthquakes, children will examine the forces at work that cause earthquakes and discover the instruments that scientists use to predict and measure these earthly tremors. A visit to Mammoth Lakes in California showcases an advanced network of lasers that measures ground movement in the area, while a fun, hands-on activity demonstrates how architects test their designs by using a shaker table. Part of the Earth Science for Children DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades K to 4.
Up, up and away! A hot air balloon, an airplane and even the space shuttle all defy the force of gravity, but they all do it in different ways. Children learn about the basic concepts that make flight possible. With clear demonstrations and a hands-on project, students will be able to understand more easily the basic concepts behind various types of flight. One of 11 volumes in the Physical Science for Children Video Series in the Schlessinger Science Library. Part of the Schlessinger Science Library for Children Collection. This title correlates to the National Science Education Standards for Physical Science -- properties of objects and materials, position and motion of objects, and light, heat, electricity and magnetism.
