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. Warm air can move things. Explore the principle of buoyancy with us, build a moving air snake and let a bag rocket fly.
