The Society for Environmental Education Baden-Württemberg - GUB for short - has created an explorer channel on YouTube in response to the Covid-19 restrictions. In the videos, GUB shows how to conduct easy science activities step-by-step and would like to give parents, but also primary school teachers and educators, suggestions and support on how and what you can explore with children through simple hands-on science experiments. Small experiments on the topic of electricity and the electric circuit for children of preschool and elementary school age. A simple circuit, a current conductivity tester and a switch/Morse apparatus are built from simple materials.
