On Monday February 19th, the Webelos Den worked on The Adventures in Science requirement 3g of the Webelos Handbook. The Scouts explored safe chemical reactions with household materials by using two substances and then observed what happened when the amounts of the reactants were increased.
Working together, they inflated a balloon using baking soda and vinegar. The goal of the project was to demonstrate the power of gas produced when the baking soda and vinegar are mixed. The goal is for the balloon to be blown up by the gas created.
If your Scout did not attend Mondays meeting, they can complete this requirement at home using the following instructions:
What materials are required?
• Balloon (1)
• Small bottle (cleaned glass beverage bottle will work well) (1)
• Small funnel (1)
• Baking soda (2 tablespoons)
• Vinegar (4 ounces)
Where can the materials be found?
Most materials can be found at the dollar store.
Experiment
1. Using the funnel, add the baking soda to each balloon (two people may be needed for this; one person to hold the balloon open and the other person to put the baking soda inside of the balloon).
2. Pour the vinegar into the bottle.
3. Carefully fit the balloon over the bottle opening (be careful not to drop the baking soda into the vinegar yet).
4. Once the balloon is fitted snugly on the nozzle, hold up the balloon and allow the baking soda to fall into the vinegar.
5. Observe the chemical reaction and effect on the balloon.
6. Record observations.
