Using this interactive experiment, your young scientist can measure, mix and watch the bubbles grow! As the yeast feeds on the sugar, a chemical reaction occurs and it releases a gas called carbon dioxide making tiny bubbles. Much like sugar in our mouths creates plaque too, this visual is sure to make a lasting impression. Common ingredients you probably already have in your home make this experiment easy and entertaining.
2 tsp. yeast
1 cup of warm water
1 Tbsp. sugar
spoon or whisk
Add yeast to the cup.
Add warm water to the cup and gently stir.
Add sugar to the cup and gently stir again.
Sit back and enjoy the action!
• Make sure the water is warm, but not hot; this will properly activate the yeast.
• Do the experiment on a surface that you don’t mind getting wet! It just keeps growing!
• After testing both utensils, the whisk mixes the mixture more thoroughly and produces faster results, so use a whisk if you have one.
