The document describes an investigation using a battery, light bulb, aluminum foil, and clothespin to create a simple circuit. Students are asked to experiment with connecting the components and record their observations. The activity aims to have students explain that electricity flows through a complete circuit from the battery to the light bulb, lighting it up, and discuss that the battery provides electricity, while the aluminum foil and clothespin create a path for the electricity to flow through and light the bulb.
