Fun with Buoyancy
Grades K - 8
What is a force that pushes against gravity?
Critical Thinking / Decisions
Students use critical thinking skills to plan and conduct research, manage projects, solve problems and make informed decisions using appropriate digital tools and resources.
If the ocean is flooded with fresh water from glacier run-off does the buoyancy of ocean water change? What layer of the ocean would be most affected?
The density of a fluid is affected by several variables, including temperature and salinity. As a fluids temperature increase, so does its density. Therefore, colder salt water will sink below warmer, freshwater.
