This video summarizes student learnings from a series of workshops conducted at Disha India Community School, Padha, Haryana. Grade 6 students inferred basic ideas of current, voltage and the operating principles a battery works by investigating a water analog of an electric circuit. They built a simple battery using a water, a coin and a washer, and learnt how to measure voltage and current. Students also figured out that it is possible to increase the output voltage by connecting two batteries in series.

About STEM Gym
The STEM Gym “Guided Discovery” approach relies on the innate curiosity and thinking skills of children to help them infer and “discover” fundamental scientific concepts for themselves. In effect, the Guided Discovery approach enables children to:
1) develop deep understanding of fundamental scientific concepts.
2) discover science concepts through investigating everyday phenomena which excite them.
3) develop scientific thinking skills such as observation, hypothesis generation, analysis, inference, ...
4) develop 21st century skills such as teamwork, critical thinking, communication, problem solving.
