### How to Create Interactive Images Using Thinglink

Thinglink is a neat tool for creating interactive images. I first wrote about it last summer and have since mentioned it in a couple of webinars and workshops. Every time I show it to people, it is well received. In the video below, I demonstrate how easy it is to create interactive images using Thinglink.

Applications for Education
One way that Thinglink could be used in a  US History classroom is to have students upload pictures representative of  concepts from the Industrial Revolution then tag different parts of the images to link out to further explanations and examples. And here's an example of an interactive infographic created with Thinglink.

Thinglink is currently and advertiser on Free Technology for Teachers.

H/T to Make Use Of.

### Mount Everest, How Tall Is It? - A Mathematics Mystery

Last night I started to read Mount Everest, The Reconnaissance 1921 which I downloaded for free from Google Books. In the introduction there is a three page explanation of the methods used to measure the height of Mount Everest. An explanation of the differences in measurements is also provided in the introduction. Part of that explanation includes differences in snow fall, cyclical deviations of gravity, and differences atmospheric refraction when observations were made. I'm not a mathematics teacher and will never pretend to be one, but reading that introduction did get me thinking about a possible mathematics lesson.

Applications for Education
Turn to pages 10 through 13 of Mount Everest, The Reconnaissance 1921 and read about the difficulties of accurately measuring Mount Everest in the late 19th and early 20th Centuries. It's interesting to note that most accepted measurements were more than 100 feet higher than today's accepted measurement. Tell your students that Mount Everest has shrunk over the last 100 years and ask them to solve the mystery of the shrinking mountain.

On a mildly related note and on a promotion of a Mainer note, Snow in the Kingdom: My Storm Years on Everest by Ed Webster is one of the best books ever written about Mount Everest. If you enjoy good adventure stories and or stories about overcoming personal struggles, I think you will enjoy Webster's book. For my money, and I own two copies of it, it is far better than Krakauer's Into Thin Air.

### TechSmith Announces Changes to Jing Pro

I have been a Jing and Jing Pro user for a number of years because I think it is one of the easiest tools to use for creating annotated screen capture images and screencast videos. This morning, through Stephen Ransom and then through an email from TechSmith (producers of Jing), I learned that Jing Pro is being discontinued. To be clear Jing is not going away, only Jing Pro is being discontinued. You will still be able to use the free version of Jing to create screen capture images. If you are a Jing Pro user now, your subscription will continue until February 2013. Click here to read more about the closure of Jing Pro.

### Explain It To Me Explains Iran

I'm kind of hooked on CNN's Explain It To Me series of videos. Each video offers a nice, succinct explanation of topics in the news. One that I watched early this morning is an explanation of Iran's nuclear program and the concerns it causes. The short video is appropriate for use with high school students in a current world news course.

To follow-up on the video above, ThinkFinity has a good list of lesson plans for teaching about nuclear energy. Here is a short video explanation of how a nuclear reactor works.

### Video - The Science of Barefoot Running

One of my younger brothers owns a small running company and is a fairly competitive distance runner so I've asked him a couple of times why some people choose to run barefoot. He's explained it to me a couple of times, but this video from NPR provides a good visual of the difference in foot movement between running with shoes and running without shoes.

Applications for Education
This video could be a good little visualization to use in an anatomy and physiology lesson.
