1. 
Compare Earth to other celestial objects in our solar system. (Don't forget moons and asteroids.) What characteristics do other planets have that are similar to Earth that could make them possible to support life? 

2.
We consider water fundamental to life, so scientists think that searching for evidence of water on Mars can bring us closer to finding evidence of life there. But could other elements be more fundamental to life on Mars? Could it be possible that we are totally wrong in our expectations about life on other planets? What other things do you think we should consider in our future investigations? 

3.
Mars One is a mission with the goal of establishing a permanent human settlement on Mars. The project managers plan to land the first humans on Mars and establish a permanent human colony there by 2027. They cannot come back to Earth. Many people applied to go for this strange mission. The majority of the applicants are under 36 and well-educated. What do you think about them? Do you think they are normal people with normal lives? What is the first and last problem that they may challenge during this life? What do you do if planners send you to this mission?

          Q1: What forces can affect motion in plants?

            - (Evidence) How could you prove it? What measurements would you make?
            - (Reasoning) How is this different from not doing work?
