In Science 8 and Science 9 we have been learning about density. We looked at the properties of different liquids to see why they might stay separated into layers.
Grace took this pic of the density column as her group investigated why it layered.
(Thanks, Grace!)
Students dropped different objects in the column to see if they sank or floated. Some objects were suspended between layers!
Check out the Science 9 Blogs for student explanations about why some objects sank and some objects stayed suspended. Remember, this was the very beginning of our investigation into density...so our thoughts are still developing. :)
