ELECTRICITY GENERATION: NON-RENEWABLES

Fossil Fuels and nuclear energy still account for over 60% of the UK's electricity generation and in some countries their use is even on the rise. As well as containing clear explanations and graphics to illustrate how energy from coal, gas and uranium is used to generate electricity, this resource explores the pros and cons of each fuel source. It includes debates around nuclear safety, fracking and carbon capture and storage.

ELECTRICITY GENERATION: RENEWABLES

The drive to reduce greenhouse gas emissions means that many governments are trying to decarbonise electricity generation. But some renewables only generate electricity when conditions are right. They're also very location dependent and can often face opposition from local residents. From wind, to solar, biomass, HEP, tital and geothermal power - as well as explaining how different renewables are used to generate electricity, this DVD examiners the pros and cons of each energy source.

SHOW ME SCIENCE ADVANCED - ELECTRONICS: FIBER-OPTIC COMMUNICATIONS

Communications technology is everywhere. We send and receive information through televisions, internet, email, radio, text message and social media. This program goes into depth about how electronic communication has evolved over time. Whether using an old rotary phone or some new technology, there are basic principles behind each that many of us are unfamiliar with. Land line telephones send sound waves that are converted into electrical impulses that work with a series of switches and routing devices that open an electrical pathway to whomever you're calling. More commonly, cell phones operate by means of a modulated electromagnetic wave basically a radio. These signals connect to an electronic communications network. Metropolitan areas are divided into small networks where antennas send and receive signals depending on the user's location.

SHOW ME SCIENCE ADVANCED - ELECTRONICS: ENVIRONMENTAL APPLICATIONS

This program examines how electronics systems monitor the environment to help scientists influence certain weather conditions and understand the impact on humans and animals in a variety of scenarios. One example is the unique electronic systems developed to regulate humidity and temperature in a biome designed to emulate the Amazon Rainforest. With advancements in science and engineering, not only can we predict and limit the impact of environmental disasters, but we can imitate nature itself. Flooding is a natural disaster that affects people all over the world. Electronic river management systems are being put in place so potential flooding can be identified and possibly controlled. This program shows how we are utilizing electronics to understand environmental conditions and help to avoid disaster. As more biomes across the planet experience extremes in weather and as more natural disasters such as hurricanes and tsunamis affect densely populated areas, this technology will increase in importance.

SHOW ME SCIENCE ADVANCED - ELECTRONICS: SCIENCE OF CIRCUIT BOARDS

Peer inside any electronic device and you will see at the heart of that device, a printed circuit board. These boards which used to connect just enough capacitors and resistors to run a simple transistor radio are now used to run all of our electronic devices. New technology has shrunk the size of all of the components that attach to the board, the width of the wires that connect them and even the size of the circuit board itself. Without the printed circuit board, our world would look a lot different.

This program details the processes involved in planning, designing, and building printed circuit boards. The process begins when a design is created in computer-aided design software. Students will learn what materials are used to construct the boards as well as how the circuits are planned and built into the boards.

ELECTRICAL MOTOR SELECTION & MAINTENANCE

With Billy Harrell, Ph.D., Sam Houston State University.

For a few cents of electricity, an electric motor will do as much work as a person working an eight-hour day. Consequently, the use of electrical power in agriculture production has experienced a rapid increase. Learn about motor selection (mechanical and electrical considerations), identify the proper information needed for motor replacement and understand maintenance techniques necessary to preserve electrical motors. This Microsoft® PowerPoint® presentation helps students maximize their electrical power use.

ELECTRICAL TOOLS, SAFETY & WIRING

Focusing on basic electrical safety procedures, the DVD discusses proper grounding of tools and equipment, the purpose of over-current protective devices and the purpose and care of insulation on electric power cords. Correct usage of the tools and following safe and approved working procedures are emphasized. Proper electrical material identification also is a focus.
