Why does a magnifying glass must be held so that the light from the sun forms a circular dot to burn paper?
A magnifying glass forms a circular dot where it focuses rays of light from the sun. The focus of a magnifying glass is at a distance from the surface of the glass itself. So a magnifying glass must be held [approximately] perpendicular to the line joining the sun and the target, and at a distance from the target which equals the focal length of the lens.

How do you separate wooden marbles from glass marble?
One possible way to separate wooden marbles from glass marbles is by using a magnetic field. Since wooden marbles are typically not magnetic, while glass marbles are also not magnetic, one can use a strong magnet to attract and separate the wooden marbles from the glass marbles.
