Students work together using two versions of a collaborative Dollhouse Electricity simulation. They must investigate three different circuits to determine which one best resembles the wiring in a real house. In one version, a student has control over the voltage supply for the circuit. In the other version a student has control over the resistance in the circuit.

The activity was developed in the framework of the Digi-Science project (Grant Agreement N. 2020-1-EE01-KA226-SCH-093387).
