What kind of youth league activities are good for junior high schools?

I am also a member of the league. Some of the following are activities I have encountered and some are my own ideas:

1: You can hold a positive talent competition (vocal music, musical instruments, dance )

Two: Hold a themed painting and calligraphy competition

Three: A themed essay competition

Four: Go to the orphanage to do housework voluntarily.. .

Five: Organize a group to pick up garbage and make nature more beautiful

Six: Let students make some small technological creations and inventions

Seven: Let the students make clothes from discarded items and then hold a fashion show. (Personally, I think this is both fun and educational, and students will definitely like it)

The above are purely my own thoughts. I am not an adult, and I am only in the second grade of junior high school. The above It's all based on my own opinions.
