​One of my favorite apps for the iPad has got to be Green Screen by Do Ink. This post will share some ideas which I hope you may be able to share with your students or other teachers.

[Here comes the historical background section of this post]

My past with Green Screen goes back quite a few years ago to a conference when I saw Hall Davidson speak. I had heard of green and blue screen chroma key before, in fact I still remember seeing a special effects documentary on Star Wars in the late 70's when I was a kid which introduced this effect tool - and of how I love YouTube, because someone found and posted this special called The Making of Star Wars. This link will take you just to the part about the blue screen. But it was Hall, who was the first one to show me that this idea can be applied in education. I thought, "this is so fantastic and I would love to use it in my classes". 

But, from there that idea just kind of sat. By that I mean (and I am sure this has happened to any of you have attended a conference before) I was inspired but didn’t do anything about.  About 6 months later I had a student ask me if I was OK with her recording my history lectures on her voice recorder. I said sure, but really it took me back to the moment when I saw Hall present and I thought, “What if I don’t just have her record me, but what if I recorded myself not just with audio but with video?

So this was my plan; I would set up a video camera on a shelf in the back of my room and then I would stand in front of my podium and pin a piece of green fabric behind me. I would then conduct the lecture making sure to not move so as to always keep me in the center of the shot with the green fabric behind me. The magic came back on my computer in the editing phase of this project.

I would take my PowerPoint and save it not as a .PPT but as .JPGs which meant that I would have an image saved of every PowerPoint slide. I would then take these still slide images and my green screen video and drop them into the video editor which I was (and still am) using, Adobe Premiere Elements. It was in the program where I would be the images in the back layer and then my video on the front layer. Then by using the Chroma Key feature (that is the actual terms for green screen stuff) I would make the green disappear and I would be left standing in front of my PowerPoint lecture. I moved my video to the lower left so that I would not be centered and in the end I looked like your local weather man narrating, except of talking about the 5 day forecast I was talking Mongols, Mayans and Mutual Assured Destruction. 

​After family movie night watching Apollo 13, I shared some of the real life images from the Apollo missions which NASA posted last year on their Flickr account. They uploaded over 14,000 images from all the Apollo missions. These are incredible resources that you can share with your students to really grasp what these magnitude of these missions. 

Much like any "vacation photos" you'll find often way too many scenic shots, but there are some pretty incredible ones too

For example, do you remember this scene in the movie? Its the one where the NASA team needs to teach the crew to create a modified carbon dioxide scrubber.
