Sink of Float Collection
I really enjoyed your collection as it had many articles that can help either a teacher or student when working on a lesson with density. I like how one of the articles gets the students to explore and think about to sink or not to sink. It explains how the buoyant force a fluid exerts on an object depends on how much of the fluid the object replaces. It helps me with an experiment if I ever want to do one where I can get a styrofoam ball or some other object that floats easily and a glass of water and put an egg in it and watch it sink but then add salt and stir it until the salt dissolves and watch the egg float. The article of the many levels of inquiry help design and implement inquiry instruction with the students. It helps me and anyone else understand what inquiry is. I could really use your collection in the future and think you picked really good articles!
