Laboratory apparatus are designed for specific uses and choice of apparatus impacts the quality of results
Equipment can be communicated using 2D drawings/images
Scientific diagrams illustrate how equipment is used together for practical investigations

Pupils either put too much or not enough detail into their drawings = muddled representations

Use the 'less is more' approach, and remind pupils to include labels - **clarity is key**. Allows for less detail and avoids any confusion.

Apparatus - A piece of equipment that is designed for a particular use.
Scientific drawing - A 2D representation of a piece of apparatus.
Scientific diagram - Use scientific drawings to show how equipment is set up for an investigation.
