Here Are some ideas :P

I made these up just by looking at my surroundings, hope that you can take something out of it. Oh, and I also hope that the questions aren't too long, I know it's not as simple as 'why birds fly'.1

1. Why are pennies bigger than dimes yet cost less?2

2. Why can't dogs see in color?3

3. Why do girls have so many shoes, yet only two feet?4
