The Backyard Scientist channel may be lean a little towards the "let's blow some stuff up because it's cool" but he does do some practical projects that are fun to watch. Now that I have a backyard I am seriously thinking about trying some of his projects out for myself.
Here are a few of the more interesting projects that the Backyard Scientist has done.
Molten aluminum in water beads.
Ping-pong steam engine (with liquid nitrogen).
Sending a GoPro to space.
Did you know molten salt explodes when it comes in contact with water?
Wood etching/burning with lightning.
There are plenty of "let's blow stuff up" channels on YouTube, but the Backyard Scientist tries to do science in the same style as the MythBusters. It may be for entertainment, but there is a commitment to be curious and to explore, and to test ideas and see what works. So it may not be publishable science, it does stay true to the idea of scientific exploration.
There are also a few cool ideas that would be fun (and safe) to try with young children. So if you need ideas for fun summer projects to help your children learn this is a good place to get a few ideas.
As a safety note: having worked with a few dangerous substances, and electricity before, the Backyard Scientists do not always take the best safety precautions. So as with anything hot, explosive, electrical, corrosive, or toxic, know the hazards and use common sense. But don't let that stop you from trying.

Educational YouTube Channels: Every Frame a Painting
My recommendations for educational YouTube channels are not limited to channels dedicated to history and science. I believe that there is something to be learned from any field of endeavor. In every field there are those who are good at their art because of pure talent. Then there are those who not only posses raw talent, but intentionally master their raw talent through education, training and understanding how and why their art takes the form it does.
Talent will only take you so far, and the difference between someone who is good at what they do and
someone who has mastered it, is a lot of hard work, practice and understanding how it works. All too often when it comes to videos, movies and pictures people just assume that all you have to do is point your camera and take the picture. But what differentiates a good movie from a great one is the preparation, forethought and understanding that goes into the picture.
The channel Every Frame a Painting covers the subtle aspects of cinema that make great movies. There are things that you don't even think about when watching a movie but can have a tremendous impact on your experience. Several years ago I watched the movie Seven Samurai and I remember being greatly impressed with it. At the time I didn't know that it was directed by Akira Kurosawa, one of the masters of Japanese cinema. It wasn't until years later when I watched the following video on the how Kurosawa uses movement to compose each shot that I learned that there was a reason why the movie had such an impact on me. The director was a master of his art and had intentionally composed his movies to produce strong emotional responses. He masterfully uses the art of the cinema to make experiences that his audience will not forget.
Similarly the director Michael Bay uses his craft to make engaging movies that are fun to watch. Even if you can't stand his movies, and I can't stand them, they are still very visually engaging. Understanding how he makes his movies will explain why his movies make hundreds of millions of dollars, even when the plots are full of holes and the characters annoying.
The same can be said of Buster Keaton. If you watch his movies, they are full of plot holes, the characters are annoying, but they are still fun to watch. There is a reason why Buster Keaton is still one of the best comedic geniuses in movie history.
There were a few videos on the channel Every Frame a Painting that changed the way I watched movies. I became more aware of how directors chose to compose a shot (or didn't choose, but just did the default, and therefore made a boring movie). I also learned what was possible in a movie and what I had been missing out in many american movies.
This is one channel that has changed (or maybe ruined) how I watch movies. I notice more and am aware of how the craft works.
One final note and disclaimer. Because this channel deals with Hollywood movies some of the subject matter on this channel is not for a younger audience. Some of the videos have graphic violence and the swearing is not edited out. I don't think any of the above videos has swearing, but several of the other videos do have extensive R rated swearing and violence. So if you let your teenage kids watch the videos on this channel, just screen them first.

Educational YouTube Channels: engineerguy
Just a few weeks ago I came across an excellent channel on YouTube called engineerguy, run by Bill Hammack, a professor of chemical engineering at the University of Illinois. There are plenty of videos on YouTube that show how some cool machine works, and a few that explain the science and history behind it, but typically they are one off videos and the maker never posts more. Or they have a channel filled with fluff, and only or two good videos.
The engineerguy channel has videos about topics like the alignment optical telescope used on the Apollo missions, that allowed them to fly to the moon.
What makes his videos stand out from other "how it works" videos is how he packs in so much depth into a short video in such a way that even someone with a PhD in physics can feel like they have learned something. When he explains something the insights shared can have applications far beyond the immediate topic, which is why his videos are unlike others on YouTube.
While I am a fan of engineering videos, especially "How It's Made", the engineerguy videos help me appreciate the complexity and ingenuity that went into some designs that we may take for granted.

Just to warn you, sometimes he will be explaining how something works and he will go into fill engineer mode, using technical language that most people will not understand. If there are things he mentions that you don't get, don't worry, just keep watching, it's only something that people with a PhD in a scientific field will care about. You can still pick up on what he is talking about without understanding everything. Just don't be intimidated by technical language.

Educational YouTube Channels: Mark Rober
Mark Rober started his YouTube channel to show off a Halloween costume that he made. Since then he has made many more interesting videos including one about his time as a NASA engineer working on the Curiosity Rover. What I like about his channel is that he works through ideas and shows proper ways of doing simple home based experiments. The topics of his videos are geared towards a general audience. Some of his videos have gone massively viral, including one where he explained how to "skin a watermelon".
Below is one of his videos that my nephews used to win their Cub Scout pack Pinewood Derby.

If you want to win an egg drop competition then this one will help you out.
There are many other interesting videos on his channel and there will be even more interesting videos to come.

Educational YouTube Channels: NurdRage
There are plenty of random YouTube channels out there that specialize in just about everything imaginable, including channels dedicated to blowing things up. NurdRage is one of those channels. But what makes NurdRage different from many of the other blow things up channels is they actually explain and demonstrate how to synthesize various chemicals. And they do not always do the cool, or popular chemicals either, such as thermite. The have videos about things like how to recycle copper chloride, and how to make chloroform. The reactions and processes are more applicable to college level chemistry than high school chemistry.
What I like about this channel is that because they do not focus on the common or popular chemical reactions, they tend to show things that you do not find on many other YouTube channels. They also occasionally get into the weeds of different processes and reactions to test different ways of producing the same product. Some of these processes are used in industry for making chemicals also used in other processes and manufacturing.
This channel won't be for everyone. Some may find it incredibly boring, because let's face it, most people will not be interested in watching a 10 minute video about making propionic acid. But for anyone who has an interest in chemistry beyond explosions and the iodine clock reaction, then this is the channel for you.
I saw this video and instantly went out and found a laser and a jar of peanut butter to test this. It really works.

Educational YouTube Channels: The Bible Project
Over a year ago one of the artists for a web comic that I read mentioned that they were doing artwork for something called The Bible Project. Since then I have been following their channel and watching their videos and I can honestly say that their work and explanations of the Bible are top notch. There are many channels on YouTube that attempt to discuss religious topics, but there are very few that manage to do it without either being over critical of religion, being so blindingly faith promoting to the point of churning out kitsch, or being so academic that they could raise the dead, just so the dead could be put to sleep out of boredom.
On The Bible Project channel they manage to hit the sweet spot with explanations that both the highly educated and novices would find interesting. Last year they produced a video on Holiness which I enjoyed greatly, so I took concepts from it and incorporated into an Elder's Quorum lesson. I think I got more comments, compliments and questions from that lesson than any other.
What makes these videos so valuable is they cover the history surrounding the Bible as a history of a faith, and a history and the development of a theology. It places all the parts of the Bible into a faith context while not losing the broader historical, cultural and social context in which the Bible was produced. I highly recommend this channel both for personal enrichment and for ideas of how to better teach about the Bible.

Educational YouTube Channels: The Great War
Telling the history of World War I is a rather ambitious undertaking, but producing videos every week explaining the war as it happened is a truly monumental task. The premise of the channel The Great War, is to tell the history of WWI a week at a time, exactly 100 years after it happened. To explain the channel here is an NPR interview with the creator Indy Neidell.
Currently they are half way through the war, but you can still catch up (here is the complete, week by week, list of episodes in chronological order). The episodes are generally only a few minutes long, but very informative. What really sets this series apart from all the other documentary series is you get a sense of how the war progressed from the perspective of someone who only has the small day to day, week to week, details. Usually history documentaries focus on topics, or single events or important series of events such as a battle or campaign. But this series by covering the war a week at a time immerses us in the true scope of the war and how it would be perceived by someone who lived it.
Indy Neidell also covers topics or events generally ignored in most history classes, because he has the time to address the small things and to build a narrative around them. For example he had an episode about Poland in WWI, which isn't talked about much because Poland wasn't an independent country at the time. Or his episode on South Africa and their involvement with the war. On the channel they also put out special episodes to cover specific topics such as Lawrence of Arabia, or Shell Shock.
This series is both an incredible introduction to WWI, and a great resource for learning about the war in depth. Most educational video series only serve as a good introduction to a subject, but this series goes beyond that into a great academic resource. It is not something that should be missed.
As a note, this series deals entirely with WWI, and as such may not be appropriate for small children. The series uses historical footage from news reels which occasionally includes the aftermath of battles.

Educational YouTube Channels: Periodic Videos
Periodic Videos is all about chemistry. Produced by Brady Haran, he interviews and films researchers, usually at the University of Nottingham, while discussing elements and chemistry in general. Sir Martyn Poliakoff, who was knighted in part for his work with the channel, features prominently in the videos. What is interesting about the channel is they generally show raw footage of their chemical experiments. They film many of their videos in the labs at the University of Nottingham, so you get to see what a real lab looks like, as opposed to a studio setting seen in many science shows. Some of their more interesting videos include putting a cheeseburger in hydrochloric acid, and explaining how to use flour to blow up a piano.
Some of their videos are the "Let's see this blow up" type, but they also have videos on each element, and others where they discuss certain reactions and compounds that are interesting, and not explosive.
Young children will not be interested in these videos, but starting about middle school or high school kids may find these videos interesting.

Educational YouTube Channels: Crash Course
Crash Course is a YouTube channel run by Hank and John Green. John Green is a famous author, most well known for his novel The Fault in Our Stars. I began watching Crash Course almost since the very beginning with their first series on world history. The first video I watched was Mesopotamia: Crash Course World History #3. Since then they have covered topics such as Biology, Chemistry, U.S. History, and Literature. They have also branched out with more presenters to cover topics such as Astronomy, Economics, and Physics.
The topics are presented at about the high school level, and in some cases roughly correspond to the associated AP classes. I do not watch all the shows, there are some topics that I enjoy more than others (history), and some that I can't watch because, well, I teach it (physics) and I go, "Oh, yeah that. Skip!". But for people who are just learning it, they present a good introduction, while also being engaging and interesting.
There is some high school level humor in some of the shows, but that should be expected. I recommend this for high schoolers or for anyone who wants a good introduction to a particular topic.

Educational YouTube Channels: Extra Credits
Much like my last post, this YouTube channel recommendation may make you go, "Really? But it's all about computer games."
Extra Credits is a channel devoted to computer games. And that may make some people automatically assume that there can be no educational value to the shows, but this is a channel with surprising depth. The topics they cover are all related to computer games, but they touch on psychology, graphics design, economics, education, and history. Here are just two examples of shows that may surprise you.
They approach the topic of games in such a way that their shows are interesting, even for those who do not play computer games at all. When they cover topics such as game mechanics, they also cover things such as writing and good story telling, and those shows have made me reconsider how I write and sometimes how I interact with my students. Some of the shows have changed how I approach teaching, so while they are all nominally about games, the applications go far beyond computer games.
What introduced me to this channel actually wasn't the shows on computer games, but their shows about history. A couple of years ago a computer game company, wanting to promote one of their games, decided to fund a few episodes entirely about the history of Rome. Since then Extra Credits have done a number of history episodes about a variety of topics, including the story of John Snow, the father of epidemiology, a history of the Zulu empire, the South Sea investment bubble, and a brief history of the Japanese invasion of Korea in the 1500's. One of their more interesting series was a short biography of Mary Seacole. If you have heard of Florence Nightingale, but have never heard of Mary Seacole, then you need to learn about Mary, and this is a very good introduction.
This channel is another unexpected gem. It may be all about computer games, but if you watch it you will realize just how much educational material goes into developing and producing games. Even if you do not watch any of the shows about computer games, at least watch their shows about history, you will definitely learn something.

Educational YouTube Channels: Forgotten Weapons
This is one that will surprise many people, but the YouTube channel Forgotten Weapons, run by Ian McCollum, is perhaps one of the underappreciated gems of YouTube. Yes, the channel is all about guns, but he manages to pack in an incredible amount of history, engineering and weapon design into each video. I started watching because he had some interesting videos demonstrating some cool historical weapons, but I stuck around because of the incredible history behind the guns. For example, did you know that that Norway developed a combined knife-pistol for their mailmen in the mid 1800's? I didn't.
Or take this early Browning harmonica rifle (which sold at auction for $120,000).
This gun channel is not like others which emphasize the "macho" aspect of guns. Ian is more like the Bob Ross of guns. He keeps it calm, informative, and well researched. If you watch this channel for a while you will learn more about guns than you ever though possible (for example, ever wonder if a gun with a curved barrel would actually work? Well you can watch a video and find out.).
This is one of those channels where some parents may be concerned because it is all about guns, but there is an incredible amount of firearm history and gun engineering, presented in a non-sensational way, that I highly recommend it. You will also learn how different guns work and along the way learn about some of the most innovated solutions to mechanical problems in history. The thing that really blows me away (haha) about this channel is learning about how guns have evolved over time, and seeing all the failed designs. Watching a lot of these videos you really get a sense that the development and progression of gun technology was not direct and straight forward, but had a lot of false starts and incredible solutions to problems you never knew existed.
This channel can also serve as a kind of nerd sniping. If you are concerned that a certain loved one may secretly have the knack, try showing them this channel and if you come back and find them watching all the videos, then you know that they will be an engineer.
Note: A very small number of his videos have incidental swearing, usually when he demonstrating the most powerful guns.
Some interesting videos:
Firing a German anti-tank gun.
4-Bore Stopping Rifle in slow motion. (he nearly gets his shoulder dislocated)

Educational YouTube Channels: SmarterEveryDay
A while back I wrote about web comics that I like, and since then I wanted to do something similar about YouTube channels that I like. So, because it is easier to write about educational YouTube channels than it is to write about things like the Late Bronze Age Collapse, or Hamlet's Mill, I will write brief reviews of educational YouTube channels. You may already know about some of these, but there will definitely be a few you have never heard of, and there will be some that will surprise you.
Several years ago I came across a channel run by Destin Sandlin called SmarterEveryDay. That was back in the day when YouTube was mostly cats and dumb videos, so it was a breath of fresh air to find an interesting channel. I think SmarterEveryDay was the first channel I ever subscribed to back in 2011. The first video I remember watching was #15, which was about lightening. Since then he has put out videos about acoustic levitation, tattooing in slow motion, the direction of toilet swirls in the northern and southern hemispheres, and has even interviewed President Obama.
Destin's videos are educational, but he also brings in much more than just "education" into his videos. I appreciate that he shows his family and shows that he loves them in his videos. He also ends each video with a Bible reference.
Perhaps the most interesting video he ever did was about learning, and unlearning, how to ride a bike.
This video, and the insights he gives, are incredibly deep. You will be surprised how insightful learning how to ride a bike can be.
This is perhaps my favorite YouTube channel, and I highly recommend it to everyone of all ages. If parents are looking for good quality educational videos for their children to watch, this is the best place to start.
