Water on Mars!

I have read different places about water on Mars, but I had questions about the evidence. This podcast helps explain and show the evidence. This podcast is good for anyone interested because it shows pictures and explains how water formed these “blueberry” rock formations, it explains that hematite’s placement and possible reason for existence on Mars, and it explains that water probably existed more than just from a comet collision which could have brought water. I do have to say that it is repetitive near the end because of similar questions at the end.

What we need to know!

This article is useful because it is an explanation of the reasoning behind the redefinition of planet. It also explains what a dwarf planet is and a small solar system body. It gives a new mnemonic device to remember the planets, “My Very Entertaining Mother Just Served Us Noodles,” which is good for elementary teachers to help their students remember them. The best resource in this article is a chart which gives information such as the planets and other solar system objects’ IAU designation, diameter and more.
