The 9 nastiest things in your supermarket 1. "Pink slime" The gross factor: The meat industry likes to call it "lean finely textured beef," but after ABC News ran a story on it, the public just called it what it looks like — pink slime, a mixture of waste meat and fatty parts from higher-quality cuts of beef that have had the fat mechanically removed. Afterwards, it's treated with ammonia gas to kill Salmonella and E. coli bacteria. Then it gets added to ground beef as a filler. Food microbiologists and meat producers insist that it's safe, but given the public's reaction to the ABC News report, there's an "ick" factor we just can't overcome.

Math Fair – natbanting.com History In late May 2015, one of my Grade 9 students had the idea to take some of our favourite classroom tasks to elementary school students. Two weeks later, the class was working alongside approximately 70 elementary school students (and future high school colleagues) at mathematical stations in the school’s small gym. The £10 cardboard bicycle you CAN ride in the rain By Mark Prigg Published: 11:15 GMT, 17 September 2012 | Updated: 15:34 GMT, 17 September 2012 A bicycle made of cardboard may seem an unlikely form of transport - but one inventor claims to have developed one that costs just £10 to make. By folding over sheets to double their strength, he claims the machine is durable, waterproof and costs very little to produce. Everything apart from the brakes and chain is cardboard - including the seat.

The Best Resources On Differentiating Instruction My colleague Katie Hull-Sypnieski is leading a February 1st Education Week Webinar on differentiating instruction, and I would strongly encourage people to participate. Katie’s the best teacher I’ve ever seen…. In addition, Katie and I have co-authored a piece for Education Week Teacher on the topic that will be appearing there soon (it’s appeared: The Five By Five Approach To Differentiation Success), and an upcoming post in my blog there will be talking about it, too (that two part series has also appeared). I also did a second two-part series in Ed Week on differentiation. Also, check out The Best “Fair Isn’t Equal” Visualizations. Given all that, a “The Best…” post was inevitable, and here it is.

3 Acts - Pop Box Design - Embrace the Drawing Board Ever wonder why companies make the decisions that they do? My wife and I drink more pop than I am willing to admit, and one thing I noticed while at the store is that the twelve packs of Coke and Pepsi do not have the same design. Let's look at them (warning I do not know if this works in the States). This is also a precursor to this lesson. Act 1 - The Boxes I asked my students which one uses the least amount of cardboard, and in relation, which company made the best choice for the environment?

15 Options for Creating Screen Capture Images and Videos - Including on Chromebooks For the next few days I'm taking some time off to relax, play with my dogs, and ski with friends. Rather than leave the blog dormant for a few days, I'm re-running some of the most popular posts of the year. TechSmith Snagit is a screen capture tool from the producers of the popular screencasting tools Jing and Camtasia. Nature by Numbers – ETÉREA Artists and architects have used since ancient times many geometrical and mathematical properties: we could take some examples simply by observing the refined use of the proportions by architects from Ancient Egypt, Greece and Rome or other Renaissance artists like Michelangelo, Da Vinci or Raphael. But what is more surprising for me is that many of these properties and mathematical developments are also present in nature. We could find countless cases, but I wanted to refer only three of them on this short animation: The Fibonacci Series and Spiral / The Golden and Angle Ratios / The Delaunay Triangulation and Voronoi Tessellations. This section is meant to be a complement to the animation, in order to better understand the theoretical basis that you can find behind the sequences. It was also, more or less, the appearance of the screenplay in the days that I was planning this project. The animation begins by presenting a series of numbers.
