It's That Time Again...

Daylight Saving Time ends today for many of my friends in Europe and it ends next Sunday for those of us in North American states and provinces that observe Daylight Saving Time. As someone who gets up early and lives in a northern state, I welcome the change as I'll see the sun an hour earlier. And hopefully, my kids will take advantage of the "extra" hour of time for sleeping next Saturday night.  

Like I do almost every time Daylight Saving Time begins or ends, I have gathered together a handful of short video explanations about why we have Daylight Saving Time. Take a look and see if there is one that can help you explain Daylight Saving Time to your students. 

National Geographic has two videos titled Daylight Saving Time 101. The first one, published in 2015, is a bit more upbeat than the second one that was published in 2019. Both versions are embedded below. 





The Telegraph has a 90 second explanation of Daylight Saving Time. The video doesn't have any narration so it can be watched without sound.



CGP Grey's video explanation of Daylight Saving Time is still a good one even if it isn't as succinct as the videos above.



TED-Ed has two lessons that aren't specifically about Daylight Saving Time but are related to the topic. First, The History of Keeping Time explains sundials, hourglasses, and the development of timezones. Second, How Did Trains Standardize Time in the United States? explains the role of railroads in the development of the timezones used in the United States (and most of Canada) today.

It's Time to Change the Clocks

I'm one of those rare people who actually likes turning the clocks back in the fall. Sure, it means that it gets dark earlier, but I'm an early riser and like seeing the sun in the morning. This weekend we're changing our clocks and if you are too, your students might have some questions about why we change the clocks in the fall and spring.

The following videos offer concise explanations of Daylight Saving Time.





Although it's not about daylight saving time, this TED-Ed lesson about the standardization of timezones is worth watching.

3 Short Lessons About Daylight Saving Time

Where I live there are two clear reminders that winter is coming soon. First, we've had a little bit of snow twice in the last five days. Second, this weekend we're setting our clocks back by one hour. If your state or province practices Daylight Saving Time, you'll be rolling back your clocks before bed and gaining back that hour of sleep you lost in the spring. Students may be wondering about the reasons for Daylight Saving Time. The following videos offer concise explanations of Daylight Saving Time.

Change Your Clock, Have a Heart Attack? - Daylight Saving Lessons

In most of North America this weekend we will be moving our clocks forward by one hour for Daylight Saving Time. Last night's edition of NBC Nightly News had an interesting story about the correlation between moving clocks forward by one hour and an increase in cases of heart attacks. The video of the story is embedded below.




After watching the story above your students may be wondering about the reasons for Daylight Saving Time. The following videos offer concise explanations of Daylight Saving Time.



And although it's not about daylight saving time, this TED-Ed lesson about the standardization of timezones is worth watching.

Five Short Lessons About Daylight Saving Time and Time Zones

This morning my dogs woke me up exceptionally early even by their standards. They did it because they don't understand Daylight Saving Time. And as my sister is fond of pointing out, neither do young children. If you're looking for some quick lessons about Daylight Saving Time to share with your students, take a look at the videos below. These are the types of videos that I would post on my high school classroom blog as "that's interesting and might appear as a bonus question somewhere" material.













And though it's not about daylight saving time, this TED-Ed lesson about the standardization of timezones is good.

Four Video Explanations of Daylight Saving Time

Tonight many of us will be turning our clocks ahead one hour. On Monday, some students may be asking why we do this. Other students, mostly teenagers, will just be complaining about the lost hour of sleep. Here are four video explanations that you can share with them. The first two I've shared before, but the second two are new to me.
