Electronics and robotics
Electronics and robotics projects for class 1 to 5: 2 ideas.
Each project below opens to its own page with what it shows, the science behind it, the materials, safety, step-by-step instructions, what you should see and viva questions. Many can be made from things at home; where a kit helps, the page links one.
Other subjects for class 1 to 5: Physics, Chemistry, Biology, Maths, Earth and space, Environment, Computing and coding.
Conductor or insulator? Tester with one cell and a bulb
Some materials let electric current pass and some do not. A bulb lights up when the circuit is complete and a conductor is in the gap.
Cardboard lighthouse that lights with one cell and a bulb
A complete circuit with a cell, a bulb and a switch makes light. A lighthouse model shows how light guides ships at night.
