Use example equipment set ups for students to look at.
Students often struggle to translate scientific diagrams into a practical set up. By providing an example set up, you are giving the students a Rosetta Stone – an aid in translation. This prevents students asking you “is this right?” over and over, and prevents dangerous or wasteful set ups.
By having both the diagram and an example students will rapidly improve their scientific drawings and experimental set-ups.
