Science project ideas for my cousin in 6th grade?

Any project ideas that are:

1. Beneficial to the society

2. Can be done by a 6th grader

3. Materials should be easily available and sourceable

I don’t know, if I am asking in the correct place, but feel free to either provide suggestions or redirect me to another community.
