Hands-on science activities that fizz dazzle kids, while teaching them real science concepts. Most fizzy chemical experiments for kids are demonstrations in which chemicals such as bicarbonate soda and citric acid combine, causing a reaction. These types of lab experiments can create edible items, make things fly into the air, produce bubbles and cause explosions.
Some chemistry experiments create items that are safe to eat or drink. One fizzy experiment is making a lemonade soda drink. Kids enjoy sodas and creating a lab version teaches them about the reaction between a base and an acid. The kids will first squeeze lemon juice from a lemon into a tall glass. An equal part of water should be added to the lemon juice. One teaspoon of baking soda is added to the mixture and the drink should bubble up to create carbon dioxide from the chemical reaction of citric acid and bicarbonate soda. Sugar may be added to sweeten the soda.
Fizzy chemistry experiments also include propelling rockets from chemical reactions. Make a lemon juice rocket with a cork and an old soda bottle. Be sure the cork fits tightly into the opening. If it does not, wrap tape around it until it is a snug fit. Attach strips of paper towel to the cork with tape to make it look like a rocket. Place one teaspoon of baking soda into one square of toilet paper. Fold it together to create a small packet. Pour lemon juice into the bottle until it is roughly one inch from the bottom of the bottle. Add water so it is slightly less than half full. Take your bottle outside and add the baking soda packet. Cork it and shake it gently. The cork should zoom into the air.
Create bubbles with a fizzy chemical experiment with baking soda and vinegar. This activity demonstrates density, or the relative heaviness of objects. Place 1/4-cup of baking soda into a clear container and add 1 cup of vinegar. The combination should bubble and fizz. Blow bubbles from a store-bought bubble mix with a bubble wand into the container. These bubbles should float on top of the bubbles made from the baking soda and vinegar, which are filled with carbon dioxide. The reason is that the carbon dioxide bubbles are heavier and denser than the bubbles filled with air.
A classic fizzy chemistry experiment is to make an erupting volcano. Craft the volcano base with a paper plate, paper cup and aluminium foil. Tape the cup to the centre of the plate and wrap them with aluminium foil to create a volcano shape. Cut a hole where the cup is to create an opening. Put play dough over the foil to make it look like a real volcano. Fill the cup inside the volcano with 2 tablespoons of water with two drops of red food colouring. Stir in a tablespoon of baking soda. Pour in 2 tablespoons of vinegar to watch the volcano explode.
