Would it be accurate to explain to 8th grade students that buoyant force illustrates Newton's third law in that gravity exerts a downward force on a fluid and the fluid, in turn, exerts an equal and opposite force on earth? Further explaining that since it is a fluid, that the reactive force occurs not just downward but in all directions including upward. I need to make a strong connection between gravity and buoyancy without getting too heavily into formulas. I know that pressure and depth are part of this system but am not sure that I need to integrate these variables in the introductory portion of the topic.
Thank you for any insight that you can provide.
