Density demonstrated with a liquid stack is a perfect way to teach this concept using a DIY science experiment. And I love these experiments in this series because they all use products you typically find around the house!! Be sure to scroll to the bottom of the page to see other videos from this series!!
For this experiment, you’ll need corn syrup, colored water, rubbing alcohol, vegetable oil, and dish soap to make a rainbow inside a bottle, then watch as each liquid moves depending on its density. Prepare to be wowed by the magic of science.
If you are looking for a great homeschool curriculum that covers density, you need to investigate Apologia!! If your children are elementary aged, look at their Chemistry and Physics Textbook. And you can also find lessons in their Middle School General Science Curriculum as well as their Chemistry Textbook!
