Lesson by lesson Objectives for #32 Electricity:
Lesson 1: To discover by trial and error how to light a bulb with a dry cell and foil ribbon.
Lesson 2: To further explore by trial and error the different ways to light a bulb with a dry cell and foil ribbon.
Lesson 3: To use the idea of contact points in predicting whether a bulb will light. To test theses predictions by experiment.
Lesson 4: To learn how to connect cells in series and opposition. To understand how this affects bulb brightness.
Lesson 5: To learn how to connect cells in parallel. To understand how this affects bulb brightness.
Lesson 6: To use a bulb and cell to test whether common materials in the classroom are conductors or insulators.
Lesson 7: To construct a circuit puzzle. To find, by trial and error, those holes that are connected by foil and those that are not.
Lesson 8: To make a bulb holder, and complete construction of a dry cell holder for use in future activities.
Lesson 9: To make a switch and integrate it into a simple circuit. To study how alternate pathways around the bulb and switch affect the circuit.
Lesson 10: To learn to draw simple circuit diagrams using accepted symbols. To predict how electrons should flow through the wires.
Lesson 11: To practice mapping and drawing more complicated circuit diagrams. To predict how electrons should flow through these circuits.
Lesson 12: To learn how to connect dry cells and bulbs to achieve maximum brightness.
Lesson 13: To understand why electricians wire buildings in parallel rather than in series.
Lesson 14: To understand how length and diameter affect electrical resistance in wire.
Lesson 15: To watch a miniature fireworks show! To appreciate that high electrical resistance can create heat and light.
Lesson 16: To appreciate that the flow of electricity decreases with increased resistance.
Lesson 17: To understand how fuses work to protect circuits from shorts and overloads.
Lesson 18: To explode a balloon with electricity by throwing a switch. To understand the role of electrical resistance in this dramatic process.
Lesson 19: To build 2-way switches and integrate them into a circuit. To understand how they work.
Lesson 20: To trace the flow of electricity through pairs of light bulbs. To recognize unusual series and parallel connections.
