A 3-volt light bulb can be illuminated using a battery, the bulb, and one wire. There are several ways to light a light bulb in a simple circuit. A closed circuit results in the bulb lighting, while an open circuit prevents the bulb from lighting.
Students will be able to:
- Discover two ways that a battery, bulb, and wire can be connected that result in the bulb lighting.
- Use symbols to diagram two ways that the system works, and two ways that the system does not work.
- Formulate two questions that could be answered by using the battery, bulb and wire; and design and conduct tests to answer the student-generated questions.
