Presenter notes: Open with a question rather than a definition. Ask the class to name something in science they have never actually seen with their own eyes. Expect answers like the inside of the body, the whole solar system, an atom. Write three on the board and leave them there, because the lesson answers all of them. This is the last topic of Unit 1, so mention that at the end you will look back across the whole unit.
