Everything is easy to understand, if you start in the right place. I explain science by starting with six basic ideas: direction, force, matter (stuff), energy, distance and time. All other ideas are built up from these key concepts. There are lots of animations along the way to illustrate what we normally can't see because it is too fast, too slow, too big, too small or invisible. I am an A-level physics teacher working in Devon, England.
