DIY Wind Turbines and How They Work

Earlier this week TED-Ed published a new lesson titled How Do Wind Turbines Work? The video covers the basics of how the turbines harness the power of wind to generate electricity. The basic math of wind turbine design is also explained to viewers of the video. Overall, it's a fine lesson but not the most detailed of lessons. If you want students to learn more about how wind turbines work, consider having them build their own small wind turbines. 

Microsoft's Hacking STEM website offers a detailed project guide for building model windmills and wind turbines. Not only will students build the windmills, they'll also capture data generated by their windmills. The data is captured in real-time through the use of Arduino and the Data Streamer add-in for Excel. Students then analyze the data to evaluate the effectiveness of their windmill and wind turbine designs. 

Microsoft's Hacking STEM windmill activity is great if you have the time and resources required to do it. If you don't and you'd like a little less in-depth windmill project, take a look at Instructables. There you will find dozens of windmill and wind turbine projects ranging from relatively simple cardboard creations to full-fledged turbines capable of powering appliances. 

Finally, if you haven't seen the TED video of William Kamkwamba sharing his story of building a windmill, you need to watch it. It's the basis of the book The Boy Who Harnessed the Wind

Join Me for the 2021 Practical Ed Tech Virtual Summer Camp

For many years teachers from all over the world came to Maine join me for the Practical Ed Tech Summer Camp. While I was hoping to return to an in-person format, this summer I’m going to host the Practical Ed Tech Summer Camp as a virtual event.

Just like last year's Practical Ed Tech Virtual Summer Camp this year there will be three sessions available. Each session will consist of ten live webinars hosted over the course of five days. You can register for the June, July, or August session.

Live and on-demand!
I realize that the schedule is not perfect for everyone. That's why every live session is also recorded. Everyone who registers has access to the recordings for a year!

You Should Attend!
Anyone who has an interest in learning new ideas for using technology in education is welcome to join and learn. In the past I’ve had teachers of all subjects and grade levels participate. Some have returned for multiple years. Teacher-librarians, instructional coaches, principals, and professors have all participated in past editions of the Practical Ed Tech Summer Camp.

You don’t need to be a “techy” person to participate and learn. All you need is a willingness to learn and a connection to the Internet.

Discounts and More!

You can learn more about the Practical Ed Tech Virtual Summer Camp right here.

Register through the ticketing page by May 1st and use the discount code "April21" to get an extra $25 off the early registration price.

Group discounts are available to schools/ districts registering five or more people at the same time. Email me at richard (at) byrne.media for more information.



What's Hidden Behind a Bitly Link?

Bitly is a handy URL shortener that I've used for many years. As a registered user I can create custom, shortened URLs that people can actually spell. I use these whenever I need to share a link to a Canva or Google Slides presentation because the default URLs provided by those services are always long and incoherent. 

Unfortunately, not all Bitly users are using them for good reasons. Some people use them to hide nefarious links. Fortunately, there is an easy way to quickly determine what's behind a Bitly URL without actually clicking on the link. The trick is to simply add a "+" to the end of any Bitly URL. When you add the "+" the URL will redirect to Bitly instead of to whatever the original URL was. That will then show you the Bitly page on which the shortened URL is hosted and will show you what the original link was. 

You can try this trick with a URL that I recently shortened. Bit.ly/THWTAPRIL will lead you directly to a copy of the slides that I used in my recent Intro to Teaching History With Technology webinar. Bit.ly/THWTAPRIL+ will lead you to the Bitly page where you can see my original presentation URL and see when I created the shortened URL. 

Watch this short video to see how you can use the "+" trick to find out what's hidden behind a Bitly link. 



Applications for Education
Building good digital citizenship and cyber safety skills is something that all of us should be helping our students do. Showing them little tips like this one to avoid clicking on suspicious links is one of the ways that we can help our students build their digital citizenship and cyber safety skills.

How to Change Camera and Microphone Access Settings in Chrome

On a fairly regular basis I get questions from readers that go something like this, "I'm trying to use Flipgrid but my camera won't work. What can I do?" A variation on that question asks for help with a microphone. 

When you're trying to use a website like Flipgrid, Vocaroo, GoSynth, or any other site that you want to use to record audio or video you need to grant access to your computer's mic and camera. In Chrome you can do that in the privacy and security settings. You can access those settings by simply typing chrome://settings/privacy into your address bar. Then select "site settings" followed by "view permissions and data stored." Then search for the site that you want to adjust your settings for. Those steps are outlined in this short video



An alternate way to access these settings is to click on the "lock" icon in your browser's address bar while visiting the website on which you want to adjust camera and microphone settings. That option works the majority of the time, but not always.

How to Identify Which Version of Google Sites You're Using

A couple of days ago I wrote about the impending deprecation of the classic version of Google Sites and how to transition to the new version. A reader sent me a good follow-up question. That was, "is there an easy way to tell which version of Google Sites I'm using?" Yes, there is an easy way to quickly identify which version of Google Sites you're using. 

To identify which version of Google Sites you're using simply enter sites.google.com into your browser's address bar then look in the bottom-left corner of the screen. If the bottom-left corner of the screen has a "back to Classic Sites" button then you're using the current version of Google Sites. Here's a little video demonstration of those steps.
