How can I teach my kids to be responsible?

there are various activities you can start at home depending on your kids' age that will help them become more responsible. for instance, i have asked my 9 year old to keep her bag ready for school the previous night, as well as get her clothes and shoes ready. also, she is supposed to make sure that all her story books and arts supply are in place after she has finished using them for the day. if at night i see they are not in place, i confiscate them for a day or two, which she tries to avoid at all costs. for my younger one, i have asked her to water the plant a certain amount and when she does it, she gets a star. also, finishing her food on her own, drinking a said amount of water each day and such small yet important tasks also get her stars that she loves :)
