INTRODUCTION:
The purpose of the Bubble Lab was to answer the question of what solutions produce the largest bubbles. Bubbles made at home, as a general rule, consist of water and dish soap. Depending on the solution, the sizes of the bubbles produced will vary. Our experiment was to make three equal mixtures of soap and water, and then put a half teaspoon of sugar in one and a half teaspoon of salt in the other.
HYPOTHESIS:
Our hypothesis was that both the salt and sugar would decrease the size of the bubbles.
MATERIALS:
we used three plastic drinking cups, liquid dish detergent, and spoon, water, table sugar, table salt, and a drinking straw!
PROCEDURES:
First we got the cups, and put water in it about half full, then we got the soap and put about a teaspoon in each cup. In the first cup we put about a teaspoon of salt, in the second we put a teaspoon of sugar, and in the third we didn't put anything. we stirred them until they were well stirred, and got a straw and blew bubbles. we observed the bubbles of each of them, and came to the conclusion that the ones with sugar in them made the bubbles the best.
DATA:
we just observed the bubbles and made conclusions on why they might work better with certain other things added to them! and found that sugar made the bubbles stronger, and more colorful!
DISCUSSION:
The sugar worked the best, then the salt, and then the regular, we didn't know exactly why it worked that way, but that just they way it was. The sugar made the bubbles have a more colorful shine to them, which made them more amusing to look at! It was a relatively easy lab to do... and came with good results!
CONCLUSION:
Our hypothesis was wrong, because we thought that the sugar and salt would make the bubbles worse, but when we did the experiment we found that it was just the opposite, that the salt and sugar both made the bubbles better, and that the normal bubbles were not quite as good as the others, even tho all of them worked!
