Usually in science we draw diagrams of apparatus rather than pictures. Diagrams areeasier to draw, and make it easier to see how the apparatus is joined together.
Imagine that you could cut the apparatus in half. You draw what you would see whenyou look at the edge – this is called a cross-section diagram.
Here are some diagrams of apparatus that you might use.
Apparatus Name Diagram What it is used for
Test tube Storing or mixing solids and
liquids
Boiling tube Heating solids and liquids
Beaker Holding liquids or solids
Conical flask (i.e. cone-shaped) Holding and mixing liquids
Round bottom flask Heating liquids
Measuring cylinder Measuring volumes of liquid
Liebig condenser Cooling a vapour and
condensing it into a liquid
