Materials Needed:
Tap Water
Dish Soap
Drinking Glasses
Spoon
Penny
Paper Towel
Project Procedure:
1. Create a table in your lab notebook like the one below.
Type of Water | Trial 1 | Trial 2 | Trial 3 | Average |
Regular Water | ||||
Soapy Water |
2. Fill a glass with tap water
3. Fill a second glass with tap water. Add a few drops of dish soap and mix gently with a spoon
4. Use the bulb on the Pipet to suck some of the plain tap water into the Pipet
5. Place your penny on a flat level surface
6. Use the Pipet to drop one drop of water onto the center of the penny
7. Continue slowly adding drops until the bubble of water on the penny bursts and spills over the edges.
8. Make sure and record the number of drops it took before the bubble burst
9. Dry off the penny and repeat steps 5-7 twice. Record the number of drops in the table each time
10. Repeat steps 4-7 with soapy water. Again, be sure to record your data in the table
11. Calculate the average drops it took for each of the two kinds of water
12. Based on the number of drops for each attempt, do you think adding soap increased or decreased the surface tension of the water?

Water
Orange Juice
Nail Polish Remover
Pen and Paper for Notes
Project Procedure:
1. Pour 80ML of each liquid into its own beaker. Make sure to keep track of which liquid is in which beaker by either labeling the beakers, or placing markers near them.
2. Set the beakers in a dry location at room temperature.
3. Monitor the levels of the liquids for 1 week and note any differences.
4. Which liquid evaporated the most? Which liquid evaporated the least? Did they all evaporate the same amount?

Materials Needed:
3 Glass Jars
Graduated Cylinder (for measuring liquid)
Distilled Water
Liquid Dishwashing Soap
Light Corn Syrup
Pipe Cleaners
Permanent Marker
Project Procedure:
1. Use the table below to make 3 separate bubble solutions in the Mason Jars, label these according to their ingredients.
Ingredient | Solution #1 detergent only |
Solution #2 detergent + glycerin |
Solution #3 detergent + corn syrup |
Water |
1 cup (240 mL) + 1 Tbsp (15 mL) |
1 cup (240 mL) | 1 cup (240 mL) |
Detergent | 2 Tbsp (30 mL) | 2 Tbsp (30 mL) | 2 Tbsp (30 mL) |
Glycerin |
-----
|
1 Tbsp (15 mL) |
-----

Corn Syrup |

|
1 Tbsp (15 mL) |
2. Now make a pipe cleaner wand for each solution. Pinch a pipe cleaner in the middle and give it a kink. Bend one half of the pipe cleaner into a circle and twist together at the center. Repeat with the other two pipe cleaners, and make sure that all 3 wands are approximately the same size.
3. Go outside and test your bubble solutions. Blow a bubble and catch it on your wand. Immediately start the stopwatch and time how long the bubble lasts. This will take some practice, so try it out on some extra solution before you start!
4. Repeat the experiment as many times as possible for each solution.
5. Record your data in a data table like this one:
Solution #1 - Bubble Time (secs) | Solution #2 - Bubble Time (secs) | Solution #3 - Bubble Time (secs) | |
Trial 1 | |||
Trial 2 | |||
. . . . . . . | |||
Trial 20 | |||
TOTAL | |||
Average Bubble Time in Seconds |
6. For each bubble solution, calculate the average time in seconds that the bubbles lasted. Do this calculation by adding up all of the data for a solution, and dividing by the number of trials for that solution.
7. Make a graph of your data. For each solution, make a bar of the average time in seconds that the bubble lasted.
8. Analyze your data. Which formula worked the best?
