Daniela school trip to go to Borneo

Because as the importance of the learning of maths and science it is extremely important to help the learning of people or communities in need. I am in year eight and as part of social learning, my classmates and I will participate in a social project to help for thirty days in Borneo. I really want to participate in this important project and help this beautiful country. 
Next year I am heading to Borneo (I hope) with my teacher and classmates, however, I need a lot of money because It is my dream to go and help but my mom can't afford this trip. I don't have the money, I am not allowed to work until I am overage, so please help me to make my dream come true.
