Happy St. Patrick’s Day! Celebrate the day with this easy science experiment featuring items you probably have on hand. This Rainbow in a Jar Science Experiment uses, water, sugar, food coloring, jars and a straw! So head to the kitchen and let’s learn about density!
Rainbow in a Jar Science Experiment
You will need:
- Four Mason Jars
- 1 jar with a narrow neck (we used a milk bottle)
- 2 cups of warm water
- Food coloring in blue, green, yellow and red
- a straw
- popsicle sticks (to stir with)
- a cup and a half of sugar
1. The first step in this Rainbow in a Jar Science Experiment is to fill each mason jar with 1/2 cup of warm water. Making sure the water is warm will help the sugar dissolve in an upcoming step.
2. Add food coloring (about two drops) to each jar, creating a blue jar, a green jar, a yellow jar and a red jar.
