电池越多，灯泡越亮
More batteries, brighter bulb
将灯泡的亮度或蜂鸣器的音量与串联电路中电池的数量和电压联系起来
Associate the brightness of a lamp or volume of a buzzer with the number and voltage of cells used in a series circuit
学习证据 / Evidence
- 描述规律：电池数量越多（或电压越高），灯泡越亮
- 解释电池越多，为电路提供的能量就越多
- 预测改变电池数量对元件工作状态的影响
- Describe the pattern: more cells (or higher voltage) = brighter bulb / louder buzzer
- Explain that more cells provide more energy to the circuit
- Predict the effect of changing the number of cells on a component's behaviour
