I cannot thank you all enough for helping sort through this. I haven't taught it just yet as the kids are just coming back from their Easter breaks. However, your insights and humor have made the synthesis a whole lot easier. Many thanks to you all.

Yes. They already have some experience with density by doing an experiment similar to the water displacement activity described in the first link. And they will be performing the activity described in the second link. I'm trying to develop my understanding of these concepts to be able to...

All of replies have been very helpful. Thank you. Perhaps I did not ask the question as clearly as I could have. What I would like to do is tie the students' developing understanding of gravity's influence on matter with the concept of why fluids have this property called buoyancy. I'm not so...

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...
