I had a conversation with my 13 year old this week that I think fits into natural consequences. He is not cheating on an exam, but cheating himself because he is lazy with his school work and just wants to do whatever the minimum amount he can do to get by.  I am so overwhelmed right now that he is basically doing school on his own.  He is perfectly capable of doing this!  He is 13 and has been homeschooled since birth, he knows the drill.  But he tend to be lazy and likes drama. So he comes to me and tries to tell me he's too tired, has a headache, can't focus, hungry, distracted by his siblings, distracted by the dog, blah, blah, blah!  I finally lost it with him a couple days ago!  I sat him down and told him this.  "You are 13 years old and you are old enough to start making some decisions on what kind of future you will have.  Dad and I have offered you the free gift of an excellent education.  We have given you the best curriculum, instruction, attention, etc.  It is kind of like the gift of Salvation.  You now have to decide it you are going to accept the gift.  I cannot make you value your education.  I know that when you are grown we will have no regrets over the education we offered you.  Now you have to decide if you want to accept this gift, get a great education and have a very promising future."
