States of Matter

The Evolution of Cell Phone Design Between 1983-2009 Cell phones have evolved immensely since 1983, both in design and function. From the Motorola DynaTAC, that power symbol that Michael Douglas wielded so forcefully in the movie “Wall Street”, to the iPhone 3G, which can take a picture, play a video, or run one of the thousands applications available from the Apple Store. There are thousands of models of cell phones that have hit the streets between 1983 and now. We’ve picked a few of the more popular and unusual ones to take you through the history of this device that most of us consider a part of our everyday lives. We have tried, wherever possible, to include the most popular phones and the phones that were “firsts” for a particular feature, but may have missed out on your favorite phones due to the sheer number of models that are out there. We invite you to post your faves in the comments section if they are not listed here. Mobile phones are just now beginning to be as vital to North Americans as they have been to Asians.

Over 70 percent of Americans: climate change worsening extreme weather Wind turbine in Minnesota, U.S. Photo by: Tiffany Roufs. According to a new poll, 74 percent of Americans agree that climate change is impacting weather in the U.S., including 73 percent who agreed, strongly or somewhat, that climate change had exacerbated record high temperatures over the summer. The findings mean that a large majority of Americans agree with climatologists who in recent years have found increasingly strong evidence that climate change has both increased and worsened extreme weather events. In the poll the majority of Americans say climate change likely worsened a number of recent extreme weather events, including 71 percent for the current drought and last year's unusually mild winter; 70 percent for this year's heatwave-rocked spring; and 64 percent for the derecho, an especially fierce and long-lasting windstorm, that hit the northeast in June.

Expérience incroyable, faire geler de l’eau instantanément ! Dans cette expérience incroyable, je vais vous expliquer comment faire geler de l’eau instantanément. C’est-à-dire que l’eau va passer de l’état liquide à l’état solide en moins d’une seconde. Cette expérience incroyable, bien que très impressionnante à l’avantage d’être extrêmement simple à réaliser. Le principe mis en évidence dans cette expérience très incroyable est la surfusion. La surfusion c’est quoi ? L’eau est un élément indispensable à la vie et à besoin de condition bien précise pour exister à l’état liquide. Eh oui on dit souvent que, pour que l’eau soit liquide il faut que la température ambiante soit comprise entre 0,1 °C et environ 99 °C, mais ce n’est pas tout ! Sur terre l’eau gel à 0 °C et entre en ébullition à 100 °C ! Sur terre l’eau reste également liquide grâce à la pression atmosphérique ! La pression atmosphérique c’est le poids de l’air qui nous entoure. Cet air exerce une pression sur tous les éléments qui l’entourent, l’eau, nous les êtres vivants, les roches, etc.

Il y aura bien entendu une suite où on abordera un peu plus en profondeur la thermodynamique et les notions, entre autre, d’énergie et d’entropie. Mais ce sera pour d’en quelques semaines car je suis pour l’instant occupé par un autre projet. J’ai eu l’occasion de visiter un laboratoire de physique à l’Université de Fribourg il y a quelques semaines et je suis en train de transcrire tout ça en dessin… Et ça s’annonce plutôt bien! - Lesson Plans & Lesson Plan Resources for Teaching Math, Science, Social Studies, Language Arts, Reading, Writing, Thematic Units, Themes, Classroom Activities - preschool, kindergarten, elementary, middle school, high school Lesson plans for teachers Common Core Implementation Kit enables the creation of a Common Core State Standards aligned lesson plan with a few easy clicks.
