Bubble Lab!!

Purpose- to test the hypothesis that bubble making can be affective by adding sugar or salt to a bubble blowing mixture.

Materials-

1. 3 plastic drinking cups

2. Liquid dish detergent

3. Measuring cup and spoons

4. Water

5. Table sugar

6. Table salt

7. 1 drinking straw for each cup 
Data-While mixing solutions cup 2 was thickest, coming in 2nd place was cup 1, then cup 3.  When done stirring for one minute, cup 2 with sugar had formed more bubbles. 
 Hypothesis-The sugar and salt will effect how the bubbles are produced. The Sugar will make the bubbles weaker so they will pop sooner while being blown.  

Procedures-

1. Label drinking cups 1-3

2. Measure and add 1 teaspoon of liquid detergent to each cup

3. Use the measuring cup to add 2/3 of a cup of water to each drinking cup

4. Then swirl the cups to form a clear mixture

CAUTION: WIPE UP ANY SPILLS IMMEDIATELY SO THAT NO ONE WILL SLIP AND FALL.

5. Add a 1/2 teaspoon of table sugar to cup #2 and 1/2 teaspoon of table salt to cup #3

6. Swirl each cup for 1 minute

7. Dip the drinking straw into cup one, remove it, and blow gently into the straw to make the largest bubble you can

8. Practice making bubbles until you feel you have reasonable control over your bubble production.

9. Repeat step 3 with the mixtures in cup 2&3.

Conclusion- The salt and sugar made no difference in the bubble production.
