The challenge: Make a Thermometer

There are different kinds of thermometers, such as electronic, glass, resistance and gas. Which of these would the Rough Scientists attempt to make with just the most basic equipment?

Firstly, what are we trying to measure?
Temperature is a measurement of how hot or cold a substance is. Temperature indicates how much energy the atoms inside the substance have. The more energy the atoms have, the faster they move and the hotter the substance. For each substance, there are specific temperatures at which changes of state happen. These are known as melting and freezing points. Absolute zero (-273^oC) is the coldest temperature that we can get to and represents the temperature at which all movement of atoms should stop. Temperature is measured in degrees Centigrade (or Celcuis) by thermometers.

Roll over the objects to discover their temperatures.
