The reason why we chose to present our thoughts by using Keynote presentations is because it is one of the easiest and most convenient way to present and share ideas. Also because all of the information can be easily presented and shared and when it is presented it can be seen clearly therefore being able to be easily understood. The ultimate reason of why we chose to use a Keynote presentation is because it can be easily constructed and it is compatible for all MacBooks.
As for the reason why we chose to talk about school, it is because we go to school everyday and we know all about the school's uses of water. Why, when and how we use water which easily gives us ideas on how we can easily conserve water without any hassle.
