THE DENSITY DRINK
To understand the tricky concept of density, you should drink it. Generally, density is fascinating. It becomes cool when you make it into a tasty, healthy beverage, which you can share with the entire class as you explain.
What you need:
• Various juices with different levels of density. [In juices, the density is measured by the amount of fruit or sugar inside it. More sugar in the fruit means that the fruit is denser. Avoid getting canned or powdered fruits. They will not work well in this experiment because they will be mostly made up of water. Do a little trial to find out which natural fruit juices are denser and more colorful than the others.]
• A turkey baster or eye dropper
• A tall, narrow glass [A taller glass makes it easier to separate the levels of density.]
How you do it:
1. Before starting the experiment, you should choose which juices are denser. From your selection, you should form a hypothesis on how your drink’s density will become. Check the juices and see their water and sugar contents.
2. Find out the least dense of all your fruit juices. Do this, so that you can display the various levels of density of all the juices you selected.
a. Get your narrow glass and fill it to about 2.5 centimeters or an inch high.
b. With your dropper or turkey baster, drop another juice onto the inner side of the glass, so that it runs down slowly toward the first juice you poured.
c. See if your second juice settles below or above the first juice.
d. Move on to the next juice, and the next.
3. Keep in mind that the juices that settle at the bottom of the glass is the densest juice. The one that rests on top of the others is the least dense of all.
4. The moment you have determined the densities of your juices, start pouring your juices into another narrow glass with the use of your baster or dropper.
5. Enjoy your density drink.
Take note that the density in liquids shows you the amount of mass or atoms in each volume. If you have 200 ml of plain water in one cup and 200 ml of sugar water in another cup, the sugar water will be heavier. The sugar molecules make the sugar water denser because they disperse throughout the water molecules.
