Mercury - a special liquid
Mercury is a special metal. It conducts heat and electricity like other
metals, but it is the only metal that is liquid at room temperature.
Mercury is also very dense. 1 cm3 of mercury is much heavier than 1 cm3 of
most other metals.
The special properties of mercury mean that it can be used to make things
that need something that will flow, but which also behaves like a metal.
Research
• Find out two or three uses of mercury.
• For each use, find out why mercury was chosen for the job.
• List any dangers of using mercury.
• What do people do to stay safe if using mercury?
• What problems does mercury cause in the environment?
When you have gathered your information, produce a leaflet or poster
display to explain to people at a household waste recycling centre why
things that contain mercury need to be placed in a special area.
