Curated OER
Water Quality Monitoring
Students comprehend the four parameters of water quality. They perform tests for salinity, dissolved oxygen, pH and clarity or turbidity. Students comprehend why scientists and environmental managers monitor water uality and aquatic...
Curated OER
Micro-Magic With Sticky Ions
Students view a video about the formation of precipitates. They complete a worksheet that asks them to identify what makes a compound form and what holds it together.
