Exploring Density with Community Central
Youth across Lewiston have been exploring the density of fluids, including experimenting to see how many fluids they could stack on top of one another.
At the Root Cellar, Lewiston Housing Authority, and the Boys and Girls Club, the youth had five fluids to stack on top of one another. In the test tube above the stacks included: dark corn syrup (brown), dish soap (green), water (blue), vegetable oil (clear), and rubbing alcohol (red).
In past weeks youth had explored hydrophilic and hydrophobic natures of various fluids and why oil and water won’t mix together. What do you think happened when we shook our test tubes? What happened to our neatly stacked layers?
Each week, Community Central staff prepare sessions tailored to classroom science themes and youth interest. We’re having fun preparing for the end of our current theme, stay tuned!
