We wondered how air, water, sand, syrup, and other materials would change the way a balloon stretches, bounces, and reacts when pressure is applied. We decided to test different materials inside balloons to see how each one would affect the balloon’s behavior.

Your curiosity, teamwork, and creativity really showed. Keep asking “what if?” and never stop exploring — you have bright scientific futures ahead of you!
You did an amazing job making your project practical and easy to understand. Keep it up!
This is solid, especially with the discussion and interpretation slide.
