Joul was created out of the belief that we have to start small and focus on the origins: our planet's resources. It is a set of modules for young kids to playfully explore the concept of energy in an explorative, tangible way. It breaks down the energy cycle into three stages: generation, storage and usage. These are embodied in the three different types of modules. The generator blocks help understand where energy comes from and how much effort it takes to create different types of power, be it through sun, wind, kinetic energy, water – you name it! The storage blocks make it possible to save, transport and use energy. And lastly the output blocks establish the connection to the power we use in our everyday lives through fun interactions with light, motion, vibration etc. While it is focused on the kid's exploration and playfulness, it serves as a conversation starter for parents to help them introduce sustainable thinking in a more tangible and explorative way.
