What is the EXIF data stored with the photos we take?

A teacher recently asked me about location data that is stored on pictures taken with a smartphone. This information is stored alongside the photo as EXIF data (which stands for Exchangeable Image File Format), in addition to other things such as when the photo was taken, and information about the device that took it.

There is a great article on How-to geek about what EXIF data is and how to remove it if you don't want that information to be embedded in your photos.

This is another aspect of photo sharing that students may not be immediately aware of; students might not know that information such as time and place is often bundled along with the actual photo that is shared online, and could be worth discussing!

Arduino primer comic

Found this introduction to simple circuits and Arduino by Jodi Culkin. I've been interested in the usefulness of Arduino in elementary education, and this is a great beginner's resource!

The Solar System Modelled to Scale

 

Another great way to visualize the scale of our solar system.

http://www.openculture.com/2015/09/the-solar-system-drawn-amazingly-to-scale-across-7-miles-of-nevadas-black-rock-desert.html

"Wylie Overstreet and Alex Gorosh set out to create something you’ve never seen before — our solar system drawn to actual scale. Forget what you’ve seen in books, or on web sites. To depict things accurately, you need a bigger surface. A really large canvas. Like a seven-mile expanse in Nevada’s Black Rock Desert (which otherwise hosts The Burning Man Festival). It’s on this dry lakebed that Overstreet and Gorosh built “the first scale model of the solar system with complete planetary orbits” and it’s a sight to behold. Creative, industrious, and humbling. Enjoy."
