"Since demolishing 78 traffic signals and installing 80 roundabouts, the northern Indiana city of Carmel has reduced the number of accidents by 40 percent and the number of accidents with injuries by 78 percent." There's a great lesson in here somewhere. I'm not sure of the exact structure for it, but here are some of my random thoughts. Let me know if you have others: Use Googlemaps and GoogleEarth in order to determine how many traffic lights are in a specific location in a county/city. Using the calculations in this article/video, how much could the county/city that you researched in Google maps have saved if they installed traffic circles rather than traffic lights. Extension - Research the number of accidents and injury/fatality stats for the area that you've researched. Using the calculations in this video/article, how many lives would traffic circles save in this area?

Interesting video on the water cycle Interesting video on the water cycle Made me stumble on this science website as well, which seems promising: http://www.untamedscience.com/science-videos

"When you get the flu, viruses turn your cells into tiny factories that help spread the disease. In this animation, NPR's Robert Krulwich and medical animator David Bolinsky explain how a flu virus can trick a single cell into making a million more viruses." Interesting video/animation on how we get the flu. Could be an interesting resource in a unit or lesson on viruses.

A friend shared this with me and it's a good read. It also summarizes the way that many of our teachers think, and could be an interesting article to share with a teacher and have a discussion about. Ultimate, I have a huge problem with the assumptions and conclusions that are being made here: "Now I'm not calling for abuse; I'd be the first to complain if a teacher called my kids names. But the latest evidence backs up my modest proposal. Studies have now shown, among other things, the benefits of moderate childhood stress; how praise kills kids' self-esteem; and why grit is a better predictor of success than SAT scores. All of which flies in the face of the kinder, gentler philosophy that has dominated American education over the past few decades. The conventional wisdom holds that teachers are supposed to tease knowledge out of students, rather than pound it into their heads. Projects and collaborative learning are applauded; traditional methods like lecturing and memorization-derided as "drill and kill"-are frowned upon, dismissed as a surefire way to suck young minds dry of creativity and motivation. But the conventional wisdom is wrong. And the following eight principles-a manifesto if you will, a battle cry inspired by my old teacher and buttressed by new research-explain why." Why are these seen as two completely different and opposing philosophies of education? That's my question. From my experience, teasing knowledge and understanding out of children stresses the hell out of them. They struggle to give you an answer initially, but when when you are unwilling to spoon feed them or provide them with a "drill and kill" answer, they finally make a connection. In doing so you show the students that their grit and determination has helped them gather a better understanding of the material and become a better student and learner in process.

"Confucius famously urged followers to heed the Golden Rule: do to others what you would have them do to you. However, he was also famous for another concept: jen. According to Confucius, a person of jen "brings the good things of others to completion and does not bring the bad things of others to completion." In other words, jen represents our ability to make the world a better place…but also a worse one. In this lesson we'll explore the concept of the jen ratio - the ratio of positive to negative observations in our daily lives - and discuss how it influences the way we experience the world. From violent video games to inspiring hip-hop lyrics, how does the Confucian concept of jen shape our lives?" This seems like a very engaging introduction to ratios. This is a paid resource, but the media for this lesson is free and available to all.

"Reactions filmed with a high-speed camera. New videos being added every week." Could be interesting to look at the reaction in regular speed and have students discuss: "What do you notice and wonder?" Then, play the slow mo videos and see what sort of observations pop up.

"Tables charting the chemical elements have been around since the 19th century - but this modern version has a short video about each one. We've done all 118 - but our job's not finished. Now we're updating all the videos with new stories, better samples and bigger experiments. Plus we're making films about other areas of chemistry, latest news and occasional adventures away from the lab." Interesting video resources for each element on the periodic table. This type of thing might be cool for students to produce/create. They could design an experiment around an element, videotape it, and put up the videos as a class/school.

Math behind health insurance. Interesting video that could be applied to math (probability, ratios, etc.) or social studies (government spending, incentives, role of government)

I don't know if aerodynamics is a field of study in high school, but this is pretty cool. You could take this video and do something interesting with it in Logger Pro to analyze wingspeed or do something else that I'm not thinking of currently...

"These maps, published in 1932 in the Atlas of the Historical Geography of the United States and available through the David Rumsey Historical Map Collection, illustrate how arduous travel was in the country's early history. In 1800, a journey from New York to Chicago would have taken an intrepid traveler roughly six weeks; travel times beyond the Mississippi River aren't even charted. Three decades later, the trip dropped to three weeks in length and by the mid-19th century, the New York-Chicago journey via railroad took two days. And the introduction of regional airlines in the 1920s made it possible to travel 1,000 or more miles in a single day." Possible applications for Westward Expansion

"This video, taken at the direction of the US Air Force in March 1946 and now held in the National Archives, shows Hiroshima seven months after the bomb, when the city was under U.S. occupation and in the process of rebuilding."

"This map, made with data from the 1870 census, shows rates of wealth per capita in the settled United States. The scale stretches from white-"under $175 per capita"-to dark orange-"$1300 and over." (In today's terms, that range of per capita net worth would be $3,125 to $23,214.29.)" Possible uses when teaching Reconstruction

This seems like a fun and interesting way to discuss/learn several different math topics. Here's a sample lesson plan that popped into my head when I saw this post: 1. Show to students a GoogleMap/GoogleEarth image similar to the one on the website, but more meaningful to you/them. For example, several different grocery stores around your house. 2. Ask the students, "Which one should I go to?" Have the students justify their answers using the image and mathematical topics that they have learned up to this point. 3. With appropriate questioning you could work in several mathematical topics here (I know I'm missing others as well…) a. Overlay a grid on the GoogleMaps and have the students give each of the locations points on an x,y axis. Use this information to determine distance. Have a conversation if this is the best way to determine which location is easiest to access. When students start to bring up the fact that even though some points are technically closer, but could be slower to get to, bring in… b. Rates, ratios, etc. Discuss how fast you could possibly travel on each route according to number of stop signs, streetlights, speed limit etc. Have students use this information to calculate the appropriate answer.

"Mathsframe has more than 170 free interactive maths games. All resources are designed, by an experienced KS2 teacher, to help children to visualise numbers, patterns and numerical relationships and to develop their mathematical thinking. New games are added most weeks." Some of these seem more appropriate for elementary school, but there are definitely some that could serve as quick review for our 6th-8th graders. You could have students use these games for several minutes individually in the class, or have students use a Promethean board/slate to interact with the game in front of the class and discuss their reasoning for the answers they select. This could be a great informal feedback tool that would take very little prep time.
