测量地震强度
Measuring Earthquake Strength
知道科学家用地震仪测量地震；地震释放的能量会以波的形式在地下传播；震级用来描述地震的强度。
Know that scientists measure earthquakes using seismometers, that earthquakes release energy that travels as waves through the ground, and that a magnitude scale describes their strength
学习证据 / Evidence
- 说明地震仪是一种探测并记录地面震动的仪器。
- 解释地震能量是从岩石破裂的地方向外传播的波。
- 把震级数字理解为对地震强度的衡量。
- Explain that a seismometer is an instrument that detects and records ground shaking
- Describe earthquake energy as waves that travel outward from where rocks broke
- Interpret a magnitude number as a measure of an earthquake's strength
评估问题 / Assessment
如果{{name}}听到新闻报道说发生了一次6级地震，能否解释什么是地震仪、地震会以波的形式在地下传播，以及震级数字越大表示地震越强？
If {{name}} heard a news report about a magnitude 6 earthquake, could they explain what a seismometer is, that earthquakes send waves through the ground, and that higher numbers mean stronger quakes?
