I am particularly new to this subject. Can neutrino physics be understood by a 10th grade?
Neutrinos were long believed to be massless, but they actually are not. Now we know that there are three discrete neutrino masses (they are tiny). There are three different neutrino flavors, and each specific flavor has a quantum superposition of the three mass states. More on neutrinos here.
Yes, a 10th grader can learn neutrino physics, if diligent enough! I'm currently an 11th grader, and started learning particle physics in 8th grade. There is a free course from the University of Geneva on an Introduction to Particle Physics. The course requires some prior knowledge of classical physics and special relativity. But it is certainly learn-able. Another resource I would have you check out is MIT's Open CourseWare, where you can find free lectures and lecture notes on practically any topic.
