| Physics 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. Essential Questions: 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.

This is a good introduction of physics to young people. Physics can be intimidating to children, so it’s up to teachers to teach in a manner that would be easily understood. It’s hard to sell ideas or concepts that are abstract like physics. Teachers have to come up with creative and ingenuous ways to each subjects on a level that would be easily grasped by ordinary students. 8/11/2015 07:14:51 am
