Awesome Kids: 3rd Grader's experiment showed interesting results.

This awesome kid bought some potatoes in order to do an experiment for science.  She wanted to soak them in water and watch sprouts come out and grow a potato plant.  The interesting thing was that her first two potatoes didn't grow anything.  This made her curious so she asked questions.  To her surprise she found out that some potato companies spray the potato with chemicals to keep them from sprouting.  She shows the results of her experiment and the experimental process in detail.  I was quite impressed with the questions and answers she came up with.  We need to get all of our students to start asking and answering questions.  Check her video out, shes fun to listen to as she explains the process.

Awesome Kids: 16 year old invents a non-decaying bioplastic.

This young lady loved science and created a non-decaying bioplastic from banana peels.  If you want to inspire your science students with a great example then show them this video.

Science and History: The History and Future of Everything is all about Time.

This video does an excellent job discussing the our recent history and the technological age.  It then goes on to demonstrate ancient history and does a really great job at helping us comprehend how long that was.  In the video we then move on to Prehistoric history and the current theories about how old the Earth actually is.  The video doesn't stop there though, it keeps going into the history of the Solar System, Galaxy and Universe.  After think this video is almost over, we get into the future history of the Earth, Solar System, Galaxy and Universe.

In order to enjoy watching this video though you might have to suspend your belief system about creation and let your students know that these are all the theories, hypothesis and ideas that have been generated with our human understanding.  The video itself is really good.

Science: Science experiments you can do from home and the classroom.

This post isn't so much about a single video, but a Youtube channel worth subscribing to.  I taught 7th grade earth science for 12 year before moving on into tech and math.  One of the methods of getting my students involved and enjoying my class was to perform experiments and then have brainstorming activities where students asked and answered questions.  I tried to do a little science activity everyday that would only take about 5-10 minutes just to either introduce a concept or simply to get my students excited to learn about science.  In fact when I moved to the High School to teach Math, I had the opportunity to teach some of my former 7th grade students.  They mentioned all the time how much they liked my class.  I would have some fun and simply ask them, "if you had fun and enjoyed the class, tell me something you learned."  Very few students actually mentioned a single topic, but instead mentioned some of their favorite science experiments.  I encourage science teachers everywhere to make sure you show, demonstrate, and create thinking activities that go beyond the textbook.

Now on to this particular post.  I would like to promote SteveSpanglerScience Youtube channel.  He has well over 100 science demonstrations and activities that don't cost much and many are very simple to do.  In this particular science video, SteveSpanglerScience demonstrates how to create a square bubble.  I thought Spongebob was the only one could create square bubbles, but apparently it is possible.  SteveSpanglerScience does an excellent job describing the process and give a materials list.

Science (Astronomy): What is the possibility of the existence of aliens?

When you are teaching a unit on Astronomy, inevitably you are going to get into a discussion with students on the possibility of life outside of our own solar system.  In this Veritasium video, Veritasium asks people on the street whether or not they believe in aliens.  The responses are great to listen to.  The discussion of the video is more about the knowledge of how vast a galaxy really is.  If people understood how far a light year actually is, it would be less likely that anybody would believe in the alien types that visit the Earth.  In the video they show a scientist who has discovered 8 exo-planets himself and his ideas on the concept of extraterrestrial life.  Also part of the video they discuss a few methods of how scientists are discovering these exo-planets.

Science (Astronomy): Is it possible to stop an asteroid?

Bill Nye the Science Guy describes how scientists and physicists might be able to stop an asteroid as it comes closer to Earth.  He discusses the possibilities and potential methods of "shifting" an asteroids course.  One thing I liked in the science video is that he discusses some math and units of conversion dealing with weight.  He explains the science and possibilities in a manner that is very easy to understand.  This video might help you as a science teacher visually introduce asteroids to your students.

Science (Astronomy and Physics): Is there Gravity in Space?

Veritasium delivers another great video about science.  In this video the question as to whether there is actually gravity in space is answered.  The video discusses that astronauts are not actually floating in space but in reality they are falling as well as the International Space Station.  They never hit the Earth though because they are also moving forward at an incredible speed.  Gravity does affect objects in space but because of motion, objects can maintain an orbit.  Veritasium does a great job explaining this through visual connections that might help you as a teacher get rid of some of the scientific misconceptions out there.
