This site, from Scholastic, delves into past speculation that Mars could support life, beginning with the Italian astronomer Schiaparelli's talk about "canali" that he thought he could see on Mars and continuing up to modern science's examination of the meteorite from Mars discovered several years ago. But it does not make any mention of the two little Mars Rovers which are still doing their jobs out there on The Red Planet. It could be an interesting part of teaching about Mars, as long as one does not rely on it exclusively. Note: the site's Flash-based presentation is not Mac compatible.
