Here is a song I created to help my 6th grade students study. I hope you enjoy. Heat is transferred three ways, Oh, oh From one place to another in waves, Oh, oh Always moving from hot to frozen, Oh, oh Moves better through some material, Oh Convection's how energy in fluids will go When liquids or gasses are heated they grow As it expands and rises from the floor Cool air is going down, going down Convection, the way fluids transfer energy Radiation, waves are traveling through space Conduction, heat through solids, Oh Convection- they are currents Radiation- the spectrum Conduction, Yeah, it's touching, Oh Yeah Electromagnetic waves go through space, Oh, oh The sun comes down with all its rays, Eh Heating an object transferred by waves, Yeah Examples- a campfire and microwaves, Yea..eah The spectrum is radio through gamma rays You feel the rays of the sun on your face Since there's no air or water in space Radiation brings the heat, to this place Convection, the way fluids transfer energy Radiation, waves are traveling through space Conduction, heat through solids, Oh Convection- they are currents Radiation- the spectrum Conduction Break it down, Ow, Come on, Ow, Let's go, Ow I touched the hot pan when I was cooking Ow, Ow, Ow, Come on I'll be screaming out when I feel the sting Conduction's the transfer of heat of things joined It happens when substances directly touch Conductors will make the heat travel faster Good ones are copper, iron, steel, silver Convection, the way fluids transfer energy Radiation, waves are traveling through space Conduction, heat through solids, Oh Convection- they are currents Radiation- the spectrum Convection, the way fluids transfer energy Radiation, waves are traveling through space Conduction, heat through solids, Oh Convection- they are currents Radiation- the spectrum And Conduction

This Shape Memory Metal (Nitinol) engine is driven by hot water! You may recall the famous Thermobile, created in 1985 by Frederick Wang. The Heatmobile is a similar design, although offered as a simple self-assembly kit. It is essentially a heat engine that demonstrates the conversion of heat into mechanical energy. It uses the unique property of Nitinol alloy called the "memory effect". Once Nitinol has been formed into shape at high temperature (about 600º C) and allowed to cool to room temperature, it can be easily deformed. However, when heated above a transition temperature (in this case about 70ºC to 80º C) the Nitinol object abruptly returns to its high-temperature shape with substantially more force than that required to deform it when cold. Heatmobile uses a Nitinol wire formed into a closed loop that drives the two connected wheels. However the high temperature shape of the wire is straight. So when the bottom part of the wire loop is heated by the water, it tries to deform into a straight shape. This action provides a torque at the bottom wheel, and causes it to rotate. As the wire goes up around the top wheel, it is cooled by the air.

http://wp.me/p1kr7x-7q I slowed down the video to show when the violation occurred. Key: 1. The first clip was a legitimate traveling violation on Taj Gibson. This was a travel, and it's always good to see that the refs are paying attention to this detail in traffic. Too often players get away with this kind of thing.Unfortunately they weren't fair. 2. Bosh receives a pass at the top of the key and takes a full step to his right without dribbling. Asik comes out to contest, and Bosh has an open layup. I could argue he traveled twice here, but the first violation is the type of travel I want to bring attention to. The ref was looking right at him! 3. Bosh receives a pass outside the 3-point line, and, without dribbling, he takes a full step to get to his spot. Hits the jumper. 4. Bosh receives a pass from Wade on the right block, without dribbling, he takes a hop to his right. He still has his dribble and his defender must account for a pump fake. The result of the play is a jumpshot from one of his sweet spots. 5. LeBron James picks up his dribble. Stops. Takes two steps forward, and finds Chris Bosh for a layup. 6. Udonis Haslem catches the ball from Wade in the lane while landing on his left foot; does not dribble, takes a step and a hop, and scores a layup.

We've been RV snowbirds for 8 winters in a row, mostly in the Desert Southwest. This year, for the very first time, we'll be spending the winter in the RV in a northern location. FEATURED & RELATED PRODUCTS AVAILABLE ON AMAZON: Heat Tape: http://amzn.to/2E0OWeK Slunky: http://amzn.to/2E0Abc9 Pressure Regulator: http://amzn.to/2GJ6tKn Kozy World Infrared Propane Heater: http://amzn.to/2FGpsnw Kozy World Heater Feet Kit: http://amzn.to/2DZtB9J 0000 Steel Wool: http://amzn.to/2E1utXl Granted, the Lower Mainland of British Columbia isn't exactly Manitoba when it comes to winter, but we're far enough up in the mountains to get some freezing temperatures and snow here. We show you all the steps we're taking to winter in our motorhome. We'll demonstrate how to keep the water hose from freezing and how to keep ourselves warm too. We'll cover water hose insulation, heat tape, the differences between all five sources of heat we have available, moisture & humidity control, and even pest control. We'll also be using our Extend-a-Stay (also known as a Stay-a-While or an Extend-a-Flow) to connect to a large external propane tank. SInce this is our first time dealing with winter in the rig, we've done a lot of reading and learned a lot from our friends and neighbors up here in beautiful, friendly BC. The site we're on has 30-amp electric, so we have to be particularly aware of our power usage. Luckily, Birgit & Greg, whose site we're using, were nice enough to let us tap into their super-size external propane tank (we'll be paying for the propane we use, of course). So propane shouldn't be a problem, but we'll still want to keep our usage to a minimum, since it's expensive, and propane use can cause excess moisture to build up in the rig. There are lots of RVers who know way more than we do about RVing in REAL winter deep freeze conditions, but we wanted to give other cold weather newbies a feel for some of the steps we've taken to prepare for it. We've seen a lot more online about winterizing an RV for storage, and we wanted to add some information about living on board too. NOTE: We mention using fine 0000 steel wool in this video. It is EXTREMELY FLAMMABLE, and care should be used in storing and using it. To see our video demonstrating how to start a fire using only steel wool and a 9-volt battery, click here: http://www.youtube.com/watch?v=YjYecQeQ7_A The piano music is my own performance of Scott Joplin's Maple Leaf Rag from 1899. WONDERING WHAT'S THE BEST GEAR TO USE ON YOUR RV? Here's all of our favorite equipment that we use ourselves and recommend to friends: http://thervgeeks.com/our-favorite-gear/ Join us at http://TheRVgeeks.com for more great RVing content! Full-Time RVers since April, 2003, we share DIY (do it yourself) RV maintenance, repair, travel, upgrade and operational tips & tricks. Many RVers are eager to learn more about using, maintaining and caring for their rigs. We hope our experience can help others go DIY, saving time & money, plus the satisfaction of a job well done. We're handy RVers, not professional technicians. We're happy with the techniques and products we use, but be sure to confirm that all methods and materials you use are compatible with your equipment and abilities. Regardless of what we recommend, consult a professional if you're unsure about working on your RV.

We payed one of my friends to let us slap him in the face with Duct Seal. Anyone in the construction business knows what it is. Anyone who doesn't, its a type of glue that is put on Duct ( what your A/C and Heat travels through, inside your house, business, building. And it is very sticky, lucky enough it was water base so it came off pretty easy.

In my travels I am often asked how hot does it get in Arizona (USA). When I say 110+ is not uncommon during the summer, they respond with... "but it's a dry heat". Although I completely agree it is a dry heat, it often takes your breath away. Enjoy this video titled "The Arizona Egg Fry"

I get so upset that LeBron travels multiple times every game and doesn't get called. So I'm going to start capturing them and posting them online. Game 4 of the Eastern Conference finals, with the game on the line. Here, LeBron takes 2 steps, stops, moves his right pivot foot twice, then moves his left pivot foot for good measure.

What makes no!no!so unique is that it is based on Thermicon technology. It is similar to laser hair removal but with one big difference. While lasers relies on light and the heat generated by that light, the no!no! is solely heat based. It works by emitting a gentle pulse of heat which travels down to the hair follicle and prevents hair growth from taking place. Put simply - the NONO heats the hair, the hair heats the hair follicle and the follicle is destroyed by the heat. Simple! Thermcon technology is revolutionary because it doesn't target the melanin in the hair follicle like a laser does, and for this reason people with dark skin or blond, red, white or gray hair are able to use no!no! without any risk of burning or skin discoloration. Watch this video to know more about it.

Canned heat bluze, Here is a little traveling story about this song. As you can guess, this song has the soul of me, and not only me, but of a lot of whom I met in my travels, this song is a international travel song That I have been playing and always, everyone digs it for sure, and my blues version, well, between the soul, and the blues that a traveler can get on a journey, well, needless to say... an example, last day in Peru, after a year there exploring the unbeaten path, discovering a whole new world, I decided to go to a gringo hotel as I waited for the plane, There was a Frenchman with a guitar playing in the restaurant, a German sitting with him, and some how or another, a Englishman and a Canadian ended up in my room along with them, I already gave away all my possessions in Peru, but I had my slide with me. I proceeded to play this song, and well, it hit all our souls, and even the Frenchman and German new the words in English, and we all just sang away at this, as it truly is the international song of all time, any tramp that goes where others only dream of, well, not only do they know the song, they live it, all in the search for whatever is around the bend. An using a guitar in my travels, has taken me, to places, that a tourist can not find, its all apart of the cosmic plan of thumbetis, god of the hitch hikers, and add the good karma of only doing good and doing no harm, well, what a wonderful journey it has been, and now, after a break, of 2 years or so, I'm getting ready to do it all again, so for the next 3 months, I am playing and playing and writing and playing, getting ready for the next travel of where ever it may lead. Peace to all that understand, what the soul of this song truly means, and may this version, if you decide to play it yourself Like I did, bring you all the cosmic karma of what it all truly means in a journey, where life is great where you never would expect it, Peace and God speed..

Mechanism of The Seasons The seasons result from the Earth's axis being tilted to its orbital plane; it deviates by an angle of approximately 23.5 degrees. Thus, at any given time during summer or winter, one part of the planet is more directly exposed to the rays of the Sun. This exposure alternates as the Earth revolves in its orbit. Therefore, at any given time, regardless of season, the northern and southern hemispheres experience opposite seasons. The effect of axis tilt is observable from the change in day length, and altitude of the Sun at noon (the culmination of the Sun), during a year. Seasonal weather differences between hemispheres are further caused by the elliptical orbit of Earth. Earth reaches perihelion (the point in its orbit closest to the Sun) in January, and it reaches aphelion (farthest point from the Sun) in July. Even though the effect this has on Earth's seasons is minor, it does noticeably soften the northern hemisphere's winters and summers. In the southern hemisphere, the opposite effect is observed. Seasons result from the yearly revolution of the Earth around the Sun and the tilt of the Earth's axis relative to the plane of revolution. In temperate and polar regions, the seasons are marked by changes in the intensity of sunlight that reaches the Earth's surface, variations of which may cause animals to go into hibernation or to migrate, and plants to be dormant. During May, June and July, the northern hemisphere is exposed to more direct sunlight because the hemisphere faces the sun. The same is true of the southern hemisphere in November, December and January. It is the tilt of the Earth that causes the Sun to be higher in the sky during the summer months which increases the solar flux. However, due to seasonal lag, June, July and August are the hottest months in the northern hemisphere and December, January and February are the hottest months in the southern hemisphere.
