Over the past 40 years, some lobstermen in South Thomaston, Maine, say that they could "set their watches by the start of the lobster shedding event each season. In 2012, though, extreme warm ocean temperaturesan ocean heat wavecombined with early and repeated lobster shedding. The obvious changes in lobsters during this event galvanized many lobstermen to take the impacts of climate change seriously.
Students determine the refractive index of a liquid with a simple technique using a semi-circular hollow block. Then they predict the refractive index of a material (a Pyrex glass tube) by matching it with the known refractive index of a liquid using the percent light transmission measurement. The homemade light intensity detector uses an LED and multimeter, which are relatively inexpensive (and readily available) compared to commercially available measurement instruments.
Students control small electric motors with Arduino microcontrollers to make simple sticky-note spinning fans and then explore other variations of basic motor systems. Through this exercise, students create circuits that include transistors acting as switches. They alter and experiment with given basic motor code, learning about the Arduino analogWrite command and pulse width modulation (PWM). Students learn the motor system nuances that enable them to create their own motor-controlled projects. They are challenged to make their motor systems respond to temperature or light, to control speed with knob or soft potentiometers, and/or make their motors go in reverse (using a motor driver shield or an H-bridge). Electric motors are used extensively in industrial and consumer products and the fundamental principles that students learn can be applied to motors of all shapes and sizes.
Computer-controlled servos enable industrial robots to manufacture everything from vehicles to smartphones. For this maker challenge, students control a simple servo arm by sending commands with their computers to Arduinos using the serial communication protocol. This exercise walks students through the (sometimes) unintuitive nuances of this protocol, so by the end they can directly control the servo position with the computer. Once students master the serial protocol, they are ready to build some suggested interactive projects using the computer or “cut the cord” and get started with wireless Bluetooth or XBee communication.
A lively, informal look at earthquake research conducted by NSF's NEESWood project, featuring a full-size, three-bedroom house built on an indoor "shake table" at the State University of New York at Buffalo.
The Nature of Geographic Information is an orientation to the properties of geographic data and the practice of distance learning. The purpose of this course is to promote understanding of the Geographic Information Science and Technology (GIS&T) enterprise. GIS&T is the intersection of professions, institutions, and technologies that produce geographic data and render information from it. It is a rapidly growing and evolving field. Learning is a way of life for all GIS&T professionals. With this in mind, I hope that this text may contribute to your lifelong exploration of how geospatial technologies can be used to improve the quality of life-yours and your neighbors', locally and globally, now and in the future.
Students apply sound-activated light-up EL wire to create personalized light-up clothing outfits. During the project, students become familiar with the components, code and logic to complete circuits and employ their imaginations to real-world applications of technology. Acting as if they are engineers, students are challenged to incorporate electroluminescent wire to regular clothing to make attention-getting safety clothing for joggers and cyclists. Luminescent EL wire stays cool, making it ideal to sew into wearable projects. They use the SparkFun sound detector and the EL sequencer circuit board to flash the EL wire to the rhythm of ambient sound, such as music, clapping, talking—or roadway traffic sounds! The combination of sensors, microcontrollers and EL wire enables a wide range of feedback and control options.
In the Arizona desert, farmers depend on an ample supply of irrigation to grow their crops. As climate changes, irrigation managers face a host of issues to keep the water flowing.
Manganese is element number 25. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.
This book is about how to read, use, and create maps. Our exploration of maps will be informed by a contextual understanding of how maps reflect the relationship between society and technology, and how mapping is an essential form of scientific and artistic inquiry. We will also explore how mapping is used to address a variety of societal issues, such as land use planning and political gerrymandering. You will gain insight into the technical underpinnings of mapping as a science approach, complement on-going interest and activities, or provide an applied focus for research or policy.
User-friendly Geographic Information Systems (GIS) is the common thread of this collection of presentations, and activities with full lesson plans. The first section of the site contains an overview of cartography, the art of creating maps, and then looks at historical mapping platforms like Hypercities and Donald Rumsey Historical Mapping Project. In the next section Google Earth Desktop Pro is introduced, with lessons and activities on the basics of GE such as pins, paths, and kml files, as well as a more complex activity on "georeferencing" an historic map over Google Earth imagery. The final section deals with ARCGIS Online and StoryMaps with tutorials, basic exercises on pins, paths, and CSV import, and a lesson plan for creating a research project presentation on an historic building in StoryMaps. In addition to an xml file that has been uploaded here to Academic Works, the module is also a live website at https://libguides.brooklyn.cuny.edu/cs-x. The site was created with Libguides software, and is a Community Libguide that can be reused and imported into other LibGuides sites. The website also contains links to two live StoryMaps, one on an Introduction to ARCGIS StoryMaps (https://arcg.is/1SX1zH), and the second, a model assignment on the history of the Fairway building in Red Hook, Brooklyn (https://arcg.is/1nbHP).
Whether you realize it or not, when you carry a smart phone, use a navigation system in your car, or look up the nearest coffee shop on your computer, you are using geographic information. Geographic data and technologies are embedded in almost all aspects of our lives. GEOG 160, Mapping Our Changing World, explores what geographic information and data are, what makes them unique, how they are created, and how we use them. You'll explore how geographic technologies like geographic information systems (GIS), remote sensing from satellites, and global positioning systems (GPS) work together to provide us with information we rely on. You'll also become an informed consumer of the geographic content in your life.
The past decade has seen an explosion of new mechanisms for understanding and using location information in widely-accessible technologies. This Geospatial Revolution has resulted in the development of consumer GPS tools, interactive web maps, and location-aware mobile devices. This course brings together core concepts in cartography, geographic information systems, and spatial thinking with real-world examples to provide the fundamentals necessary to engage with Geographic Information Science. We explore what makes spatial information special, how spatial data is created, how spatial analysis is conducted, and how to design maps so that they're effective at telling the stories we wish to share. To gain experience using this knowledge, we work with the latest mapping and analysis software to explore geographic problems.

Paul Andersen explains how the mechanical energy added or removed from a system results from work. For work to occur a force must act parallel to the displacement of the system. Since work and energy are equivalent the work-energy theorem allows of for calculating the work as the change in kinetic energy. A force-displacement graph can be used to calculate the work done on the system.
