What is 17 days to make a difference?

Hello! I'm from Room 10 in New Zealand and My class is doing a project called 17 days to make a difference. For this project we must do at least one good thing that helps someone else every day for the 17 days. While we are doing this we must keep a diary of the good thing we did and put it in our blog. Follow me through this challenge by reading my blog each day. 17 days to make a difference starts soon. So be ready!
