The best activities for students are hanging out with family or friends, and take part in comunity activities. Because srudents now are all like indoor activities istead of outdoor activities like before. So family and school should create conditions for them to join in some community activities like camping, sightseeing, etc. If students don't like community activities, family can create conditions for them to hanging out with friends or take them to some places they like such as cinema, amusement parks, etc.
