Abstract:
Do you like playing with bubbles? Almost every kid loves to blow bubbles – and wishes that their bubbles don’t pop or evaporate so quickly! This science fair project was performed to determine if adding other substances to a bubble solution can help the bubbles last longer. Testing was done by adding corn syrup, sugar water, glycerin and lemon juice the to the bubble solution.
Procedure preview:
1.    For this science fair project, the independent variable is the additive added to the bubble solution – soap, corn syrup, glycerin, sugar and lemon. The dependent variable is the length of time the soap bubbles are able to last before bursting. This is measured with a stopwatch. The constants (control variables) are the room temperature and the mixing ratio of the bubble solution. 2.    Using the black marker pen, the 5 plastic cups are labeled as “soap”, “corn syrup”, “glycerin”, “sugar” and “lemon”. 3.    Each cup is filled with 100ml of water. Another 20ml of liquid detergent is added .....
