Knowledge You Can Drink


This is a project that enables you to create a drink, from which you can acquire great knowledge about the density of liquids. You can go ahead and drink the healthy concoction as well when you’re finished.

What you need:

• Baster or an eye dropper
• A clear, narrow tumbler or drinking glass
• Different juices (***Take note that if the juice has more fruit or sugar, it is heavier. You can test natural fruit juices and pick them from heaviest to lightest. Also, remember that canned or powdered juices do not serve this project well because they are made up mostly of water.

How to do it:

  1. Check the juice selection you gathered and write down their sugar content, water content, and ingredients. Arrange them on the work table from the densest to the lightest, based on your information.
  2. Once you’re ready, get your glass or tumbler and start pouring the juices.
  3. Take the densest juice first and pour it into the container. Always let it run down the sides of the container. Fill the bottle about 2.5 centimeters or 1 inch high.
  4. Use a baster or dropper to add in the juices.
  5. Observe which juices settle at the bottom of the container. Also, note the ones that settle at the top of the juice below their layer.
  6. The finished product is a colorful and tasty drink that tells you the story of density

How it works:

Density shows the amount of mass or molecules in the liquid—in this case, the juice. This means that a glass filled with 300 ml of sugary water is heavier than a glass with 300 ml of plain water. The molecules of sugar are dissolved in the water. We cannot see them, but they make the water heavier or denser.
