"Electromechanical Dynamics, Spring 2009"
" First published in 1968 by John Wiley and Sons, Inc., Electromechanical Dynamics discusses the interaction of electromagnetic fields with media in motion. The subject combines classical mechanics and electromagnetic theory and provides opportunities to develop physical intuition. The book uses examples that emphasize the connections between physical reality and analytical models. Types of electromechanical interactions covered include rotating machinery, plasma dynamics, the electromechanics o

The carbon cycle: what goes around comes around
Resources provided in this publication will allow you to facilitate your students’ application of carbon, carbon compounds, and carbon cycle knowledge to real environmental issues. In this way they apply knowledge, analyze issues, synthesize concepts, and evaluate proposed solutions.
Turbidity and TSS
This image-rich Streams.org website describes turbidity and total suspended solids (TSS). It includes overviews about what they are, why they are measured, how they are measured, and why they vary. The site also features links to sensor and other water quality parameters.
Water Quality For Freshwater Organisms
This website features a field activity that demonstrates the effect of water temperature on the solubility of dissolved oxygen and how it relates to the gill beat rate of fish. The activity uses the Winkler method to measure dissolved oxygen.
Tardigrada (Water Bears)
This reference page offers a brief description of Tardigrades, also known as water bears. It includes information about their physical appearance, an explanation of their name, likely habitats, internal organs and other distinguishing features, and a few images. A diagram of a common tardigrade, Macrobiotus macronyx, is also provided via an internal link.
Tardigrades: Bears of the Moss
This online PowerPoint presentation is dedicated to the phylum Tardigrada. It discusses distinguishing characteristics of Tardigrades (also known as water bears), their relationship to arthropods and nematodes, internal structures, life stages, cryptobiosis, research opportunities, classification, identification, habitat, distribution, ease of study in the lab, and more. Each slide contains illustrations and descriptions of the microscopic animal.
Fisheries Learning on the Web
FLOW is a comprehensive curriculum about the Great Lakes ecosystem with three core units: Food Web, Water and Fish. Geared toward upper elementary and middle school educators, standards-based lesson content features hands-on activities.
Australian Travel Adventure
Students will learn information about each of Australia's states and territories by researching information from Internet sites. They will then take what they have learned and decorate the outline of a car with symbols and pictures that represent information gained from their research.
Percussion: San Francisco Taiko Dojo
SPARK follows Sensei Seiichi Tanaka and Taiko Dojo as they prepare for the 36th annual International Taiko Festival at Berkeley's Zellerbach Hall. This Educator Guide is about the history and traditions of the ancient art of Taiko drumming in Japan and the contemporary innovations of a global music culture.
Sunlight and the Seasons
Children study seasonal change in sunlight in a global game of hide and seek. Students try to find 10 "mystery classes" hiding around the globe. The amount of sunlight is the central clue. Other clues link to each location's history, geography, culture, and more. Through these interrelated investigations, students discover that sunlight drives all living systems and they learn about the dynamic ecosystem that surrounds and connects them. This project reinforces a key concept: Changing sunlight d
Supercourse: Epidemiology, the Internet, and Global Health
Supercourse is a global, continuously updated repository of lectures on public health and prevention targeting educators across the world. Supercourse has a network of over 32000 scientists in 151 countries who are sharing for free a library of over 2500 lectures. Originally funded three times by NASA, and now by the National Library of Medicine, this "Library of Lectures" has been developed from passionate scientific lectures from across the world. The result is a technology for inexpensive, su
Soils as Sponges: How Much Water Does Soil Hold?
The purpose of this resource is to introduce students to gravemetric measurements - calculating the amount of water in a soil sample or other substance by weighting it before and after drying.
Just Passing Through (Beginner version)
The purpose of this resource is to develop an understanding of how water flows through different soils and how it is transformed when it flows through these soils. Students time the flow of water through different soils and observe the amount of water held and also the filtering ability of the soils. They will also observe the filtering ability of soils by noting the clarity of the water before and after it passes through the soil.
Just Passing Through
The purpose of this resource is to develop an understanding of some of the relationships between soils of different types and water. Students will time the flow of water through soils with different properties and measure the amount of water held in these soils. They will also experiment with the filtering ability of soils by testing the pH of the water before and after it passes through the soil and observing changes to the clarity of the water and to the characteristics of the soil. Students w
Soil Particle Density Protocol
The purpose of this resource is to measure the soil particle density of each horizon in a soil profile. Students weigh a sample of dry, sieved soil from a horizon, mix it with distilled water and then boil the mixture to remove any air. The mixture cools for a day and then students add water until the volume of the mixture is 100 mL. Students measure the temperature and mass of the final mixture and use the Soil Particle Density Data Sheet to calculate the soil particle density. Three samples sh
Optional Soil Moisture Sensor Protocol
The purpose of this resource is to measure the water content of soil based on the electrical resistance of soil moisture sensors. Students install soil moisture sensors in holes that are 10 cm, 30 cm, 60 cm, and 90 cm deep. They take daily readings of soil moisture data by connecting a meter to the sensors and using a calibration curve to determine the soil water content at each depth.
Gravimetric Soil Moisture Protocols
The purpose of this resource is to measure soil water content by mass. Students collect soil samples with a trowel or auger and weigh them, dry them, and then weigh them again. The soil water content is determined by calculating the difference between the wet sample mass and the dry sample mass.
Optional Soil Infiltration Protocol
The purpose of this resource is to determine the rate at which water soaks into the ground. Students place two cans into the soil and add water to them to a depth of at least 5 cm. Students measure and record the time it takes the water level to drop a fixed 2 - 4 cm distance. Students repeat the measurement to determine how easily water moves vertically through the soil.
The purpose of this resource is to become familiar with the hydrology of your locale. Students will study and visit the Hydrology Study Site, conduct a visual survey to discover information about local land cover, water quality, and document their findings. They will use this initial investigation to raise questions about local land cover and/or water chemistry issues that may require further investigation.
