What can Electricity flow through?
Posted by Karen Engelke
This week in Grade 4 science, students demonstrated that some objects conduct electricity and some do not. Students constructed a simple circuit and observed that a penny, a piece of foil, and a paper clip conduct electricity, while a plastic spool and paper index card does not. They better understood how conductors of electricity allow currents to flow freely. Meanwhile, they observed that insulators resist the flow of an electric current.
