Mad Scientists Club: Balloon Science

  • Program Goals
    • Practice following instructions/directions
    • Practice the scientific method
    • Attendance: 35
Experiment: Static Electricity
All you need for this is balloons and kids. The kids rub the balloons on their heads, the carpet, or anything else and then see what they stick to.

Experiment: Blowing up balloons with chemistry
The baking soda and vinegar one is easiest - put the baking soda in the balloon and the vinegar/water mixture in the bottle. The sugar and yeast (a couple spoonfuls of each) needs to be shaken and can take about 30 minutes to expand.
  • Supplies
    • Baking soda, vinegar
    • Sugar, yeast
    • Water bottles w/caps, balloons
    • Funnels, tablecloths, wipes, paper towels
Experiment: Spinning Penny
I got this from Steve Spangler Science. Basically you put a penny (or other small object) in a balloon, blow it up, and make it spin. It's all about centrifugal force!
  • Supplies
    • Pennies or other similar sized objects
    • Balloons
Experiment: Balloon parachutes
I really wanted to do some experiments with helium, but left it too late to acquire any. Then my aide pointed out we could just buy some helium balloons. I let the kids experiment with balloon parachutes. I had the kids create balloon baskets with paper and tape, attach them to the balloon with string, and then take turns experimenting by dropping them off the ladder with various items in the basket to see how fast they'd fall.
  • Supplies
    • Balloons, string, paper, tape
    • Objects to weigh down "basket"
    • Ladder
Instructions, questions, and facts for experiements

Evaluation

  • 3-9-17
    • Attendance: 36
    • Notes: The purchase of helium balloons worked just fine. Make sure you have all large balloons and some opaque for the penny experiment next time.
