The document discusses drawing scientific apparatus and diagrams. It provides symbols for common laboratory equipment like beakers, Bunsen burners, clamps stands and more. It instructs the reader to use the symbols to draw diagrams of three setups: 1) a beaker half-filled with water on a tripod being heated by a Bunsen burner, 2) an irregular object in a displacement can with a beaker to collect water, and 3) a conical flask half-filled with water on a clamp stand with a thermometer to measure temperature.
