In this activity children will investigate how a conductive fabric can change the brightness of a bulb.
Description
British soldiers' uniforms could soon use electrically conducting yarn woven directly into the clothing, replacing cumbersome batteries and cabling. The 'e-textiles' could provide uniforms with a single central power source. This would allow soldiers to recharge one battery instead of many and cut the number of cables required in their kit. One of the problems with conventional cables is that breakages can be catastrophic. Children will investigate how a conductive fabric can change the brightness of a bulb.
Learning Objective:
- To construct simple electrical circuits using different components
- To compare and give reasons for the difference in the brightness of a light bulb when they stretch the conductive fabric
