This seven minute video offers insights and statistics about Mars. Well done with excellent images. The red planet Mars is very much like Earth because it also has rolling plains, mountain ranges, and giant canyons. Mars, one of the rocky inner plane...ts is roughly half the size of Earth. Its core is most likely composed of iron, nickel, and sulfur. A day in Mars is 24 hours and 39 minutes long. Mars' orbit around the sun takes almost two Earth years. A Martian year lasts 687 days. This is some of the data students should take notes about if they are going to do a compare and contrast project. There is an ad at the beginning on the acceptance of those who may have a different sexual orientation.

Mars is the fourth planet from the Sun in the Solar System. The planet is named after Mars, the Roman god of war. It is also referred to as the "Red Planet" because of its reddish appearance as seen from Earth.
A terrestrial planet, Mars has a thin... atmosphere and surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts and polar ice caps of Earth. It is the site of Olympus Mons, the highest known mountain in the solar system, and of Valles Marineris, the largest canyon. In addition to its geographical features, Mars' rotational period and seasonal cycles are likewise similar to those of the Earth.
This video shows the rotation speed of the red planet Mars relative to Earth, the seasonal cycles on Mars and its surface structure.

When you take a look at Mars, you probably wouldn't think that it looks like a nice place to live. It's dry, it's dusty, and there's practically no atmosphere. But some scientists think that Mars may have once looked like a much nicer place to live, ...with a thicker atmosphere, cloudy skies, and possibly even liquid water flowing over the surface. So how do you go from something like this--to something like this? NASA's MAVEN spacecraft will give us a clearer idea of how Mars lost its atmosphere, and scientists think that several processes have had an impact. (02:01)

When you navigate with a compass you can orient yourself thanks to Earth's global magnetic field. But on Mars, if you were to walk around with a compass it would haphazardly point from one anomaly to another, because the Red Planet does not possess a... global magnetosphere. Scientists think that this lack of a protective magnetic field may have allowed the solar wind to strip away the Martian atmosphere over billions of years, and now NASA's MAVEN spacecraft will study this process in detail with its pair of ring core fluxgate magnetometers.

Ever wonder why Mars is red? Let's make sense of it with science To get to the fourth planet and find out why we see red, we're going to travel by rocket. This video explains that the rust color on Mars is really rust which means Mars once had water ...on it. Some key vocabulary words include atmosphere, surface, rust, maghemite, magnetic, and oxide. A variety of pictures is shown as well as auditory/written content. This is a great resource to help build background knowledge for our students and would work well in conjunction with reading non-fiction texts on planets, Mars, atmosphere, and/or space. (2:02)
