text: what kind of maths project should i make for class x which includes science also?   some suggestions: 1. you could do your own poll (among your neighbours or even on yahoo answers) and see how your results can be extended to a general population. this is what pollsters do for example to come up with projections in an election. you can find good references for doing the mathematical studies for such a project easily on the net.  2. you can study the evolutionary patterns of human beings - national geographic has a genographics project where they are collecting blood samples from around the world and mapping the journey of our ancestors. you could get your own journey mapped (by providing your cheek swab samples and $100) and then find out about other historical happenings through the ages and correlate the findings. this is a costly project so do your survey first before investing the $100 into the project.  3. study traffic patterns on some major road and correlate that with other events going on in your city. then make predictions for the following week and see how your model compares with the actual traffic. if you are good at programming build a small software for doing this.
