Create Your Own Density Bottle (This is a Test Grade/Summative)
Name _______________________________Due Date ______________________
Project Directions:
Carefully clean an empty clear plastic soda, juice, or water bottle (should be around 500 mL). Keep the
cap to seal it later. Let the bottle dry completely. (The bottle cannot be colored it needs to be clear)
1. Using your knowledge of the density of various liquids and solids that we have studied: create
a visually pleasing “density” bottle. You will need liquids or solid objects that will form
separate layers when poured into bottles. Be careful not to use liquids that will mix together.
Be sure to get permission from an adult before using any substances, and try them out in
small amounts first so you do not waste them.
2. On a sheet of paper (with the proper heading at the top) draw a colored diagram of your bottle
and label its contents. Make sure that you include everything that you included in your bottle.
3. Write a summary under the diagram detailing the reasons why you selected the liquids and
solids that you used to make up your density bottle. Honors: Research the densities of the
liquids and solids that you used in your bottle, compare and contrast their densities, why they
floated where they floated compared to the other substances and compare to water (1.0
g/cm³[mL]).
4. Take care to make it look nice, it’s a visual project.
List of items to use in the bottle. You will need food coloring; all clear liquids other than oils
will be able to be colored with food coloring. YOU MUST USE 5-7 LIQUID/2+ SOLIDS minimum.
