Mars is coated with iron oxide, which not only covers the surface but is also present in the rocks made by the volcanoes on Mars.
Today you get to perform a chemistry experiment that investigates the different kinds of rust and shows that given the right conditions, anything containing iron will eventually break down and corrode. When iron rusts, it’s actually going through a chemical reaction: Steel (iron) + Water (oxygen) + Air (oxygen) = Rust
Materials
- Four empty water bottles
- Four balloons
- Water
