Any ideas for science expo?? Please i'm desperate!?

We Answered:

Sorry, but I got stuck at the part where you had to pick a topic you were "interested in."

How would I know what kinds of topics interest you?

Kent Said:

Distance from mars to sun?

We Answered:

Mars is about 1.5 AU from the Sun, as compared to the Earth's 1 AU. If the size of the Sun is the size of a softball, the link below suggests, Earth should be 15 metres away from the Sun in your model and Mars 22.8 metres away. Both Mars and Earth would only be the size of a pencil dot, and Jupiter and Saturn would only be the size of marbles.
