Creating this thermostat will help to develop your child's knowledge and understanding of the world around them, and how things work. The activity will also help to improve their hand-eye coordination and fine motor skills as they cut and the stick the different materials together to make the mini-thermostat. Your child will find some of this task tricky so you'll need to be on hand to help out.
How to extend the magic
Explain to your child that washing machines have thermostats in them to control the temperature of the water that washes your clothes. Showers also have hot and cold settings so the water temperature can be controlled. Open up your fridge and show your child the thermostat inside which helps keep the food inside cool and fresh. If you have a thermostat for your hot water and central heating, you could show your child that too.
