Next Monday is Memorial Day. Students often confuse the origin and purpose of Memorial Day with those of Veterans Day. The following videos can help students understand the origins and meanings of Memorial Day and Veterans Day.
The Meaning of Memorial Day is a two minute video covering the origins of the holiday in the United States. The video is embedded below.
The U.S. Department of Veterans Affairs offers the following video overview of the history of Memorial Day.
Jocko Willink isn't everyone's cup of tea, but I enjoy his podcast and found this video that he released a few years ago to be quite moving.
Timelinely is a neat tool for annotating videos that you find on YouTube to share with your students.
To get started simply paste a YouTube URL into the Timelinely homepage to get started. Once you have entered the URL for a video, a new screen appears that allows you to add tags or annotations to the timeline of the video. You can do this while the video plays or you can simply jump to a place on the video to add annotations. Your annotations can include text or images. As you can see in the screenshot below, I included an image of my friend Tom Richey in the annotation that I made on one of his YouTube videos.
Before you get too involved with Timelinely it's important to note that you'll have to create an account in order to save and share your work. You can create an account by using your Google account, by using your Facebook account, or by signing up with any email address. You can share your annotated version of a video via email and social media.
Applications for Education
One of things that I like about Timelinely is the option to include pictures in your annotations. I can see that feature being used to include an alternate example for students to view when watching a math lesson.
I'm not sure that Timelinely is any better than a handful of similar services, but it is nice to have options
Despite the efforts of my friend Maggie, I don't always understand what makes one work of art great and a similar-looking one fit for display in a Hilton Garden Inn. I thought about that last weekend when I came across a YouTube channel called Great Art Explained. The channel seems to have been made for folks just like me.
Great Art Explained features twenty-five videos that provide ten to fifteen minute explanations of some of the works of Van Gogh, Picasso, Warhol, Monet, Hokusai, and many others. The videos that I watched over the weekend explained both the artwork itself and the life of the artist and how that influenced their artwork.
Applications for Education
Great Art Explained could be a good resource for art teachers as well as history teachers. The videos are short enough to be useful for flipped classroom lessons while still providing enough depth to spark good classroom discussions about the works.
Math in Real Life is a series of 167 TED-Ed lessons and TED Talks. The "real life" context in these lessons isn't things like "how calculating percentages helps you be a frugal shopper." The "real life" context found in the videos in the Math in Real Life series is broad in nature. For example, you will find lessons about how math is used to guide ships and calculating rates of travel in space.
We use computers every day. But how many of us actually know how they work? Sure we know how to use the software, but I'm thinking about the hardware. How does that aspect of your computer work? Code.org has a good video series that addresses that question and more.
Applications for Education
If you're planning to do any classroom projects with Raspberry Pi or Arduino, this series of videos could provide a nice primer for students. Similarly, the videos might help students complete the picture of how computers work after completing a hands-on Raspberry Pi or Arduino activity.
A couple of days ago I published a short video that I made to explain stock options. In planning to make that video I went back through my archives to look at some related resources that I've shared over the years. Here are some highlights from my archive of resources for teaching and learning about stocks, bonds, options, and economics in general.
Inflation Explained in One Minute provides a very basic explanation of the concept of inflation. It could be fine as a conversation starter or introduction to a lesson. However, if viewed on its own without additional information it might give students the impression that inflation is solely caused by changes in money supply.
How Inflation Works is an excellent twelve minute video lesson produced by CNBC International. The video does a great job of explaining demand-pull inflation and cost-push inflation. Going beyond the basics the video also provides an excellent comparison of the economic theories of Milton and Keynes. Students will also learn how the consumer price index is calculated and how it is indicative of inflation. Finally, the video concludes with historical examples of inflation around the world and the causes of those hyper-inflationary episodes. I should note that the video will lend itself to introducing other concepts to your students including the importance of the federal reserve's interest rate.
What Causes an Economic Recession? uses the context of the Bronze Age to introduce the factors that can lead to economic recessions today. Those include inflation, borrowing habits, saving habits, spending habits, and government decisions.
What Causes Economic Bubbles? uses the context of the tulip industry of the 1600's to explain what causes an economic bubble and what happens when it bursts.
How Does the Stock Market Work? is a TED-Ed lesson that provides a four minute overview of the origin of stock markets, why companies offer stock, and the basic factors that influence the prices of publicly-traded stocks.
The Open University hosts a series of six short videos intended to introduce viewers to some of the basic concepts of macroeconomics. In 60 Second Adventures in Economics you will find short videos explaining things like the Paradox of Thrift and Comparative Advantage.
As kind of a hobby I dabble in options trading (I made $6 last week). I mentioned this to a friend of mine last Friday and he, like many other people I've talked to about it over the years, said, "I've heard of that, but I don't what it means." That conversation inspired me to create a short video explanation of what options are. You can watch the video here or as embedded below.
Applications for Education
While I made the video to explain options to my adult friends, it could also be used as an introductory video in a high school business class. If your class is playing a stock market simulation game, this video might be helpful to you and your students.
One of the things that quickly became clear when I started teaching an introduction to computer science course for high school freshmen was that while they are happy to use the Internet, they don't really understand how the Internet works. I suppose the same can be said for lots of adults too. The Domain Name Systems is the most important or at least most frequently used part of how people use the Internet today. PowerCert Videos, has a good video that explains how a DNS server works. I used this video in my classroom.
Code.org offers a video on the same topic. Code.org's video gets into a bit more of the history of the development of the Internet. I also showed this video to my students, but I didn't find it nearly as effective as the PowerCert video.
Applications for Education
If you have never built a website from scratch without the use of a service like Weebly or Google Sites, you may not have ever thought about the role of IP addresses and the domain name system in getting a website online. These videos can help students understand how that process happens and how DNS makes it easy to navigate the web today.
Last week I wrote a blog post titled Two Lessons for a Wicked Cold Day. After publishing that post it occurred to me that readers who are not familiar with New England may be wondering why I chose the word wicked. Sure enough, someone emailed me last night to ask what I meant by "wicked cold." In New England we tend to use the word "wicked" as an adjective in place of extreme or very. For example, the Boston Celtics played wicked good defense against the Detroit Pistons last night.
The New England-style use of wicked originated is just one of many mysteries of vernacular. For more mysteries of vernacular lessons, take a look at TED-Ed's Mysteries of Vernacular series. Each of the 26 lessons focus on one word that is often used by English speakers. A history of the word's origins and evolution of its use is featured in each video lesson. The entire playlist is embedded below beginning with the word "yankee."
Words of the World. Words of the World is a collection of videos featuring historians and linguists explaining the origins of and history of the use of words in the English language. The videos attempt to put the words into a somewhat modern context. For example this video about the word "guerrilla" makes reference to Che Guevara. The video I've embedded below explains the word "coup."
Langscape is an interactive map created at the Maryland Language Science Center. The Langscape interactive map displays more than 6,000 markers representing more than 6,000 languages. Each marker represents the native language of that location. Zoom-in and click on a marker to learn more about the language. When you click on the marker you will be able to find more information about that marker through links to pages on Ethnologue, Language Archives, and Wikipedia. Those pages will provide information about whether or not the language is extinct and its origins.
For the last few days it has been exceptionally cold here in Maine. Birds and squirrels keep showing up at our bird feeders despite the cold or perhaps because of the cold. While looking at the birds at our feeders yesterday my youngest daughter asked how the birds stay warm enough to not freeze their feet. It was a good question and I found the answer in this short BirdNerd video.
By watching BirdNerd's How Birds Stay Warm in Winter video my daughter and I learned that some birds can regulate the temperature of their feet separately from the rest of their bodies. Watch the video to learn more about that and other ways that birds stay warm in the winter.
There are other things you can do to help birds in the winter besides putting out bird feeders and keeping them full. Those things are explained to young students in the SciShow Kids video titled How to Help a Bird.
Over the next two days here in Maine we're expecting some of the coldest temperatures and windchills of the last 50 years. As we say in Maine, it's going to be wicked cold! It's going to be so cold that kids will stay inside for recess and we'll leave the water dripping in our faucets overnight to prevent pipes from freezing. If you're experiencing some wicked cold weather right now or you're just curious about it, I have a couple of short lessons to share with you.
How windchill is calculated: The windchill is expected to reach -35F tonight at my house. The following video explains how windchill is calculated. The video comes from Presh Talwalkar.
The psychology of extreme weather: Television news reporters like to use the word "extreme" whenever we have a lot of rain or snow in a short amount of time. Is the weather really "extreme" or is that just our impression of it? The following Minute Earth video takes on the topic of how extreme weather affects our thinking about weather patterns in general. I found the video to be interesting from a psychology perspective. The video is embedded below.
One of my goals for early part of 2023 is to set a new personal best time at a bike race that I'm entered in for the third year in a row. To do that I'm watching my diet much more carefully than I typically do at this time of year. Like many people, foods that contain lots of cheap carbohydrates are my Achilles heal when it comes to sticking to my nutrition plan. Why is that? And what impact does that have on my body? Those questions and more are answered in a TED-Ed lesson titled How Do Carbohydrates Impact Your Health?
How Do Carbohydrates Impact Your Health? explains what carbohydrates are, common food sources of carbohydrates, and how are bodies use carbohydrates. The lesson also explains what can happen to our bodies when we consume too many carbohydrates.
A few nights ago I had a long zone 2 ride on my indoor bike trainer. Whenever I have one of those workouts scheduled, I queue up a favorite movie to watch. Last night I watched The Big Short starring Steve Carell, Ryan Gosling, Christian Bale, and Brad Pitt. For those who aren't familiar with The Big Short, it is a movie about how the housing and stock markets crashed in 2008 and how a few shrewd investors benefited from the crash. Watching the movie again this week prompted me to dig up some information about stocks, bonds, ETFs, and related investing basics.
Investing for Beginners is a playlist of videos produced by Fidelity Investments. Granted, the videos are from a financial services company, but they do offer a good introduction to the basics about stocks, bonds, and mutual funds.
Investopedia offers a playlist of short videos that define things like ETFs, dividends, and compound interest. That playlist is embedded below.
As the name implies, the video quiz widget in BookWidgets lets you create a video-based quiz to use directly in BookWidgets and or distribute through your favorite LMS including Google Classroom. With the video quiz widget in BookWidgets you can use your own videos or videos that you've found on YouTube to create video-based lessons and quizzes.
When you use the video quiz widget in BookWidgets you can add questions and comments directly into the timeline of a video. For example, if you want to make a clarifying comment 32 seconds into a video, you can do that. And if you want to pose a reflection question to your students three minutes into a video, you can do that. In fact, you can use any of the dozens of BookWidgets question types in the video quiz widget. In other words, you're not limited to asking multiple choice and short answer questions as you are with some other video lesson creation tools.
Later this week I will publish my own BookWidget video quiz tutorial on my YouTube channel. Until then, take a look at this tutorial from Lucie at BookWidgets to learn more about how it works.
As I do at this time every year, I'm taking the week off to ski and play with my kids, shovel snow, and generally not think about work. I have some of the most popular posts of the year scheduled to republish this week. New posts will resume in the new year.
Earlier this week a reader reached out to me with a concern about ViewPure. For many years ViewPure has been a popular tool for teachers to use to hide distracting sidebar and "related" content when playing YouTube videos in their classrooms. There are other tools like it. If you find yourself looking for alternatives to ViewPure, here are some things to try.
Watchkin is a service that provides a few ways to watch YouTube videos without seeing the related video suggestions and comments. You can enter the direct URL of a video into Watchkin to have the sidebar content removed. You can search for videos through Watchkin and have family-friendly results displayed (if a video appears that is not family-friendly Watchkin has a mechanism for flagging it as inappropriate). Watchkin also offers a browser bookmarklet tool that you can click while on YouTube.com to have the related content disappear from the page. Watch this video to learn more about Watchkin.
Quietube is a convenient tool that you can add to your browser's bookmarks bar. With Quietube installed you can simply click it whenever you're viewing a video on YouTube and all of the related clutter will be hidden from view. Installing Quietube requires nothing more than dragging the Quietube button to your toolbar.
SafeShare.tv makes it possible to view YouTube videos without displaying the related videos and associated comments. To use SafeShare.tv simply copy the URL of a YouTube video and paste it into SafeShare.tv. SafeShare also offers browser a bookmarklet tool that will eliminate the need to copy and paste links from YouTube into SafeShare.

We're planning a little trip this fall to visit some family that we haven't seen since before the start of the pandemic. When we told our daughters that we're going to fly they got very excited about it. We've now been answering questions about flying seemingly nonstop for a few days. Those conversations prompted me to compile this list of resources for teaching and learning about the science of flight.
Turbulence: One of the Great Unsolved Mysteries of Physics is a TED-Ed lesson that explains what turbulence is and the forces that create it. The lesson explains that even though we typically associate turbulence with flying in airplanes, turbulence exists in many other places including oceans.
How Things Fly hosted by the Smithsonian features an interactive module in which students design their own airplanes. The activity starts with a simple and slow airplane that students have to modify until it reaches a target speed and altitude. As students modify the wings, fuselage, and engines of their airplanes they are given instant feedback on the effects of those modifications. In some cases the feedback includes the airplane crashing and the students having to start over again.
If you have ever wondered why airlines sell more tickets than they have seats on an airplane, the TED-Ed lesson Why Do Airlines Sell Too Many Tickets? is for you. In Why Do Airlines Sell Too Many Tickets? you can learn about the mathematics that airlines use to maximize the revenue that they can generate from each flight. That math includes calculating the probability that everyone who holds a ticket for a flight will actually show up for the flight. The way that probability is calculated is explained in the video. Finally, the lesson asks students to consider the ethics of overbooking flights. Watch the video below or go here to see the entire lesson.
Last weekend we had a huge snowstorm that knocked out the electrical power in my whole neighborhood and in about half of our town. In my neighborhood we were without electricity from Friday night through Monday afternoon. Fortunately, we have a portable generator that provides electricity for the essentials in our house and we have a bunch of battery backup light bulbs that we can use in the evenings. As I walked our dog on Sunday afternoon I heard the hum of generators. That reminded me of a couple of short video lessons about electricity generation that I shared with my students a couple of years ago.
The Engineering Mindset is a YouTube channel on which I've found a bunch of great lessons over the years. One of those is AC Electrical Generation Basics. While it doesn't specifically address portable generators like the one you can find in my garage, it does do a great job of clearly explaining how electricity is generated by the parts that you'll find in a portable generator.
Can You Power a House With a Bicycle? is a video produced a few years ago by NPR's Skunk Bear. The answer is no, you can't power a house with a bicycle. The video does a great job of explaining how many bicyclists you would need in order to power an average house for a month.
Homemade Bicycle Generator was produced by Backyard Trail Builds (a channel about building bike trails and jumps). What's good about this video is that the producer explained his initial mistakes and how he corrected them. The video is also not so detailed that it doesn't inspire more curiosity about how to improve on the design.
How Do Solar Panels Work? is a TED-Ed lesson that covers the basics of what solar panels are made of and how electricity is generated from them. The video also delves into some of the political and societal barriers to solar panel installation and solar array developments.
How Do Wind Turbines Work? is a TED-ED lesson that covers the basics of how wind 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.
I'm currently reading Bill Bryson's book, One Summer: America, 1927. The book is centered around significant events of that summer including Charles Lindbergh's crossing of the Atlantic. Airplanes have come a long way since Lindbergh flew in the Spirit of St. Louis, an airplane that he couldn't see out of when looking forward. The physics of how an airplane gets airborne and stays airborne are still the same as they were 1927. A newly released video SciShow Kids uses excellent visuals to explain how an airplane flies today. The video uses both jet-powered airplanes and prop-powered airplanes to show the key concepts.
How Airplanes Fly is the latest video that I'm adding to my growing list of resources for teaching and learning about airplanes and airlines. Those resources are included below.
Turbulence: One of the Great Unsolved Mysteries of Physics is a TED-Ed lesson that explains what turbulence is and the forces that create it. The lesson explains that even though we typically associate turbulence with flying in airplanes, turbulence exists in many other places including oceans.

In last week's Practical Ed Tech Newsletter I detailed a few features of YouTube Studio that every teacher who uploads videos to YouTube should know how to use. The video included in that newsletter can be seen here. Chances are that even if you don't upload videos to YouTube, you probably use YouTube to find and show videos in your classroom from time to time. If that's the case for you, there are some features of YouTube that you should know how to use.
In this new video I highlight the features of YouTube that you should know how to use before showing a video in your classroom. Those features include adjusting the size and color scheme of subtitles, accessing and saving a transcript of videos, and clipping sections of YouTube videos.
