In science we are learning about thermometers. There are four different types of thermometers, there is a thermocouple which is used to measure extreme temperatures, a recording thermometer which is used to measure temperature over a period of time, a infrared thermometer which is used to measure things from farther away, and a bimetallic strip wich is used to control the heat.
We are also learning about the 3 states of matte and how they change for example from a liquid to a gas is evaporation and to do that you need to increase the energy. there is also gas to a liquid, solid to a liquid , gas to a solid, solid to a gas, and liquid to solid.
