Section 1
Atoms Build Matter from Elements
Matter consists of elements made of atoms, which contain protons and neutrons in the nucleus with electrons orbiting outside. The number of protons determines which element an atom represents.
In this Grade 5 lesson from Science: A Closer Look, Chapter 6, students explore the structure of matter and atoms, learning how protons, neutrons, and electrons make up atomic nuclei and how the movement of electrons produces electricity. Students also investigate electric current, circuits, and resistors through a hands-on inquiry activity in which they predict and test which bulbs light when switches open or close in different circuit configurations. The lesson builds foundational vocabulary and conceptual understanding of static electricity, grounding, and electrical pathways.

Section 2
Electrons Create Static Electricity Through Movement
Static electricity forms when electrons transfer between objects through rubbing. Objects with excess electrons have negative charge, while those missing electrons have positive charge, creating attraction or repulsion.
Section 3
Circuits Direct Electricity Through Paths
Electric circuits provide paths for electron flow from voltage sources through conductors. Series circuits offer one path where all components share current, while parallel circuits provide multiple paths for electricity.
Section 4
Safety Devices Protect Against Electrical Hazards
Fuses, circuit breakers, and ground fault interrupters protect homes by stopping excessive current flow. These safety devices prevent fires, electrical damage, and dangerous shocks in wet environments.
