How Does Air Conditioning Work? - A Lesson for the Dog Days of Summer

Here in northern New England we don't handle hot and humid weather well. The first heat wave of the summer always sends people scrambling to buy the few air conditioners that are in stock at Home Depot or Walmart. In fact, I was one of those scramblers a couple of weeks ago. This leads me to a new video from Reactions titled How Air Conditioning Works.

How Air Conditioning Works uses excellent drawings and narration to explain the inner workings of air conditioners. The video also explains the environmental impact of the chemicals that are used in air conditioners and the alternatives that are currently being explored.

Brush Ninja - Make Animated GIFs on Your Desktop or Mobile Device

Brush Ninja is a free tool for creating animated GIFs. Unlike some similar tools, Brush Ninja works equally well in the web browser on a Chromebook, Windows or Mac laptop, iPads, Android tablets, and iOS and Android phones.

To make an animated GIF on Brush Ninja simply go to the website and start drawing on the blank scene editor. You can draw as many scenes as you like in Brush Ninja. When you have drawn all of the scenes for your animation press the play button to preview your animation. If you are happy with your animation, you can download it by clicking the export option. If you don't like a part of your animation, you can go back and edit any of the scenes that you need to adjust. Watch my video that is embedded below to see the whole process in action.



Applications for Education
Animated GIFs can be a good for displaying the steps of a solving a math problem. I’ve also seen them used to illustrate parts of speech. And my friends who teach physics can use animated GIFs to illustrate key physics concepts. Those are just a few of the ways that you could use animated GIFs in your classroom.

Take a Look at TypingClub's Unique Approach to Typing Practice

TypingClub is a site that offers an extensive set of typing lessons for students. On TypingClub you'll find lessons that use a traditional approach to typing practice as well as lessons that use a rather novel approach to typing practice. That novel unique approach to typing practice is found in TypingClub's story-based typing practice. This approach presents typing practice as a story for students to write. Watch my video that is embedded below to see TypingClub's story-based typing practice in action.


As you can see in the video above, the story unfolds as students type. They type the letters that appear on the page. More of the story is revealed as students type. Feedback is provided in the form of letters changing color when students type incorrectly. Additionally, the story pauses until students type the correct letters.
