In Year 5, our DT unit was on using electronic systems in a greetings card.  We looked at electrical circuits and the components needs to make one work, then how these could be adapted to use in a greetings card.  We found out the graphite was a conductor, but it wasn’t as reliable as copper tape (which we used in place of wire).  We designed Christmas cards that had a light-up element and we used LEDs for the lights as they are small, easy to work with and powerful. We used coin cell batteries as these worked best with the type of switch that we included (we didn’t want our cards to run out of battery too quickly!) It was tricky at times to ensure our circuit was complete, with gaps in the tape where the LEDs and the battery were. We were really pleased with our end results and hope that they bring joy to our families this Christmas.
