can ne one give me some tips on a project?

Answer 1

YOU need to pick a project (a topic, a theme, an idea).

For example: building a scale model of all planets (using the same scale for all of them).
or

Making a cut-away model of the Sun.

Measuring the period of the Satellites of Jupiter, using only a small telescope and a metronome (that was my project last year).

Since we have no idea of what equipment or experience you have, it is difficult for us to help you. Do you have a favorite theme? It does not need to be one where you are already good. In fact, the whole idea of the project is for you to learn stuff.
