Teacher's Domain Video Podcasts on itunes

Infrared view of galaxySolar System view through infrared camera

Grades K-5
One of the video pod casts from WGBH (which is the Public Television station in Boston) that I found interesting was called "Infrared: More than the Eye Can See". In this video, Dr. Michelle Thaller, who is an astronomer, explains how infrared camera enable us to see light that isn't visible. In it, she explains that light you can see with the naked eye is called visible light, but another kind of light, infrared, you can only see with an infrared camera or goggles. Objects give off heat and that is what is shown on the infrared camera. Warm objects appear brighter on the infrared camera and cool objects appear darker. She showed us many examples of this in the video. Astronomers are using infrared to detect planets that give off their own heat but you are unable to see because they are not near a star that gives off light.

I watched two more videos in this age group, "Energy Flow in the Coral Reef" and "A Night in the Coral Reef". I loved both of these videos because I think children are always interested in learning more about underwater creatures. The Coral Reefs are located in tropical areas and near the surface of the water because they need the energy from the sun to survive. Some of the creatures living in the reefs are the Moray Eel and the Octopus. These two creatures are nocturnal, another fact I didn't know. They come out at night to hunt for prey and return to their caves during the day. Some of the other fish eat the coral to get at the small, small creatures that are living inside.

These videos reminded me so much of an IMAX movie I saw on a field trip last year to the National Naval Aviation Museum at the Naval Air Station in Pensacola with my son's third-grade class . It was called "Deep Sea" and was narrated by Johnny Depp and Kate Winslet. In this film, you felt like you were really under the water and that's how I felt watching these videos.

Grades 6-8
I also watched a couple of videos in the 6th-8th grade age group that I found interesting. "What is a Planet" explained what characteristics a planet must have to be classified as such and why Pluto is no longer considered a planet. They also said in the video, there may actually be 10-12 planets total though some have not been classified yet.

I also watched ""Earth as a System" because I love physical geography and learning about biomes and atmospheric changes. In this video, different characteristics of the earth were used to explain why we have different climates in other parts of the world in addition to volcanoes, earthquakes, El Ninos, etc.

I found all of the videos from Teacher's Domain to be very educational. I would use these videos in a classroom to help with science and geography lessons. Some of the videos are very short and only cover the basics but they could be used to introduce a topic such as weather or astronomy to a class before the lesson was presented.

Another useful thing I discovered from the going to itunes to watch the video casts was the Teacher's Domain website. On this website, a teacher can download the videos, which also come with an attached essay explaining the information. The resources can be saved on your desktop or in a folder in which you can share them with other teachers. To use the resources on the website, you only have to register and registration is free. The topics covered on this website range from The Arts, Language Arts, and Mathematics to Social Studies and, of course, Science. This is definitely a website I will be using as a teacher when I get in the classroom.
