Hooked On Science – Inflate a Balloon Using a Chemical Reaction
PLEASE follow these safety precautions when doing any science experiment.
• ALWAYS have an adult present.
• ALWAYS wear the correct safety gear while doing any experiment.
• NEVER eat or drink anything while doing any experiment.
• REMEMBER experiments may require marbles, small balls, balloons, and other small parts. Those objects could become a CHOKING HAZARD. Adults are to perform those experiments using these objects. Any child can choke or suffocate on uninflated or broken balloons. Keep uninflated or broken balloons away from children.
• Baking Soda
• Empty 2 Liter Bottle
STEP 1: Fill the empty 2 liter bottle half of the way with vinegar. Describe and classify the vinegar by its observable properties.
STEP 2: Fill the balloon with baking soda. Describe and classify the baking soda by its observable properties.
STEP 3: Carefully stretch the open end of the balloon around the neck of the 2 liter bottle.
STEP 4: Dump the baking soda, inside the balloon, into the 2 liter bottle, and observe. Did mixing the two substances result in a new substance?
When the baking soda is mixed with the vinegar, a chemical reaction happens, which creates carbon dioxide gas. The carbon dioxide gas inflates the balloon, causing the balloon to expand.
