Sugar Water Density Test Science Experiment

In this fun and easy density science experiment, we’re going to use sugar water to test density. 

Materials:

• Six clear plastic cups or glasses
• Measuring cups
• Measuring spoons
• Sugar
• Water
• Six different colors of food coloring
• Spoon
• Graduated cylinder or some other long and thin clear container
  
  
  

Instructions:

1. Set out the six cups.
2. Pour one cup of warm water into each cup.
3. Add one drop of a different food coloring to each cup.
4. Do not add any sugar to the first cup.
5. Add two teaspoons of sugar to the second cup.
6. Add four teaspoons of sugar to the third cup.
7. Add six teaspoons of sugar to the fourth cup.
8. Add eight teaspoons of sugar to the fifth cup.
9. Add ten teaspoons of sugar to the sixth cup.
10. Mix until the sugar is dissolved.
11. Now pour an amount of your most sugary solution into the graduated cylinder. Make sure you judge your amount so you can get an equal portion of all your solutions into the cylinder.
12. Continue adding sugar solutions, from most to least sugary into the cylinder. Do so gently to avoid disturbing the lower levels.
13. If everything works as planned, you should have a sugary rainbow density demonstration.

How it Works:

As the sugar dissolves into the water, the water becomes more dense. The solution with the most sugar will be the most dense. You are able to layer the different solutions by their amount of sugar as the less dense solutions will float on top of the more dense solutions. The food coloring allows you to easily distinguish the different layers and observe density. 

Make This A Science Project:

Try making solutions with different items like salt. Try making solution by dissolving different numbers of candies like Skittles in each cup of water.
