Ocean Density Bottles Classroom Warm Up

Classroom Warm-ups: Kick-off any lesson with these one-page, observation-building, problem-solving STEM prompts — whether or not you’re teaching an ocean topic.

Ocean water is more dense than pure water because of its salinity, or the concentration of salt in a given volume of water. This activity will help students to visualize and understand how water density plays  vital role in oceanic environments.
