Explain what’s happening at the atomic level when a battery is used to turn on a light bulb.
Students think through key ideas of atomic theory. For example, some atoms hold on to electrons better than others and that like charges repel and opposite charges attract. After exploring key concepts, students decide which statements best explain the flow of electric current through a conductor.
This is image compares a Bohr type model of a conductor and insulator. The key idea is that the conductor has free electrons that are loosely held by the nucleus, and the insulator is made of a compound that has tightly held electrons in an organized lattice matrix.
Assess your students’ abilities to:
Develop effective scientific explanations to learn more about static electricity.
Decide which illustrations accurately show the relationships between positively and negatively charged electrons.
Learn more about the different models used to describe atoms and elements.
