1) Temperature, Heat, and Pressure" Please respond to the following:

• Watch the video titled "Heat and Temperature Introduction" (2 min 30 sec) under the Temperature and Heat terms section of the Science Corner. You can also view the video at https://www.youtube.com/watch?v=v1zOnyC4RgQD. Next, describe the fundamental differences and similarities between temperature and heat. Then, analyze how heat transfer occurs during the processes of conduction and convection. Provide one (1) example of where each occurs in natural physical systems.
• Watch the video titled "USGS Gas Hydrates Lab" (6 min 44 sec) under the Gas Hydrate terms section of the Science Corner. You can also view the video at https://www.youtube.com/watch?v=U46XOoU0DrM#t=12. Next, explain the main reasons why pressure and temperature play a critical role in the stability of gas hydrates. Identify at least two (2) situations where methane hydrate deposits predominantly occur and discuss the key challenge(s) in locating and harvesting methane hydrate under each situation.
• Suppose it is a very hot summer day and you want to cool your kitchen. Unfortunately the windows and doors in your kitchen cannot be opened. You have either a fan or a refrigerator to cool the kitchen. Which do you believe would be more effective to cool the room? Explain your answer then try testing your theory.

2) "Pressure, Temperature, Electricity, and Magnetism" Please respond to the following:

• Read the article titled "Aging US Power Grid Blacks Out More Than Any Other Developed Nation" under the Smart Grid terms section of the Science Corner. You can also view the article at http://www.ibtimes.com/aging-us-power-grid-blacks-out-more-any-other-developed-nation-1631086. Next, assess the efficiency of the current state of the national electric grid in the United States. Then, describe the key challenges in updating this grid to a so-called "smart grid".
• Read the article titled "Earth's Inconstant Magnetic Field" under the Earth's Magnetic Field terms section of the Science Corner. You can also view the article at http://www.nasa.gov/vision/earth/lookingatearth/29dec_magneticfield.html. Next, summarize the main reasons why the researchers stated that "our planet's magnetic field is in a constant state of change". Then, discuss the overall manner in which a magnetic reversal might impact human activities on Earth. Include one (1) example of such impact to support your response.
• Demonstrate an instance of static charge such as seen with examples #32 and 33 shown on page 209 of your textbook. Next, post a picture of your example then explain the method of charging you used as well as the charges displayed in each object.

3) The Electromagnetic Spectrum" Please responds to the following:

• Watch the video titled "What Are Gamma Rays?" (1 min 39 sec) under the Gamma Rays terms section of the Science Corner. You can also view the video at https://www.youtube.com/watch?v=PPlrtgilgK8. Next, give your opinion on whether or not the benefits of space exploration to the Moon and Mars outweigh the risks and costs of exposing such travelers to gamma rays above Earth's atmosphere. Provide a rationale for your response.
• Watch the video titled "Video Tour of the Electromagnetic Spectrum" (5 min 3 sec) under the EM Spectrum terms section of the Science Corner. You can also view the video at http://missionscience.nasa.gov/ems/emsVideo_01intro.html. Next, describe one to two (1-2) ways that you encounter and utilize electromagnetic radiation in your daily life. Note: Feel free to include both naturally occurring examples, as well as any man-made technologies.
• Choose a technology device that makes use of the EM Spectrum. Next, explain how this device works using terminology learned in this chapter.
