DATA   ANALYSIS

Throughout the entirity of the experiment there was no range of living and nonliving worms because they all had died, except the experiemntal control that had no detergent . No matter how strong or week the concentration was there was a 100% mortality rate across every detergent.

Hypothesis

If four worms are exposed to different types of detergent then the detergent that is more natural will cause the least amount of harm to the worms because the detergent is made from more natural products vs. toxic/artificail chemicals.

Exposing the

Making a Dilution Series of Each Detergent

  1. Label Paper cups with the name of the liquid detergent and the percent concentration, as follows:

    1. Detergent Name: 0%

    2. Detergent Name: 3%

    3. Detergent Name: 6%

    4. Detergent Name: 12.5%

    5. Detergent Name: 25%

    6. Detergent Name: 50%

    7. Detergent Name: 100%

  2. Mix the detergent solutions before diluting them. Pour one of the detergents into the beaker and mix it by stirring with a clean plastic spoon. Avoid forming bubbles.

  3. In the cup labeled 100%, add 100 mL of liquid detergent.

  4. In the cup labeled 50%, add 100 mL of liquid detergent and 100 mL of water.

  5. Stir gently, but thoroughly, with the plastic spoon to mix the water and detergent.

  6. In the cup labeled 25%, add 100 mL of 50% detergent (made in the previous step) and 100 mL of water. Stir to mix.

  7. In the cup labeled 12.5%, add 100 mL of 25% detergent and 100 mL of water. Stir to mix.

  8. In the cup labeled 6%, add 100 mL of 12.5% detergent and 100 mL of water. Stir to mix.

  9. In the cup labeled 3%, add 100 mL of 6% detergent and 100 mL of water. Stir to mix.

  10. In the cup labeled 0%, add 100 mL of water.

  11. Cover the cups with foil after dilution made.

  12. Repeat steps 1–11 with clean materials to create the dilution series for each detergent.

 

Exposing the Worms to the Detergent

  1. Poke several holes with a toothpick in the bottom of six empty paper cups.

  2. Label the cups with the name of the detergent, the date, and the percent detergent, as follows:

    1. Detergent Name, date, 3%

    2. Detergent Name, date, 6%

    3. Detergent Name, date, 12.5%

    4. Detergent Name, date, 25%

    5. Detergent Name, date, 50%

    6. Detergent Name, date, 100%

  3. Add 80 grams (g) of potting soil to each cup. Use the electlectric balance to measure 80g.

  4. Add 100 mL of liquid from the dilution series to the appropriate cup.

  5. Mix the detergent into the soil with a clean spoon.

  6. Add four worms to each cup.

  7. Cover the cups with aluminum foil and store them in a cool area, away from direct sunlight or hot air from a heater vent.

  8. If the room temperature is very hot for part of the day, store the worms in a refrigerator until the room temperature cools off.

  9. Make sure that the soil stays moist and the temperature does not get too high.

  10. Repeat steps 1–7 for each of the three additional detergents. You should have 19 cups with worms in them when this section is completed (six for each of the four detergents and one control with no detergent added).

 

Analyzing the Effects of the Detergents on the Worms

  1. After five days, pour the contents of the cups, one at a time, onto a surface covered with newspaper. Make sure to keep track of the detergent and dilution for each batch of worms.

  2. Record how many worms are alive or dead for each detergent and dilution.

  3. Compare the "green" detergents with the conventional detergents.

  4. Repeat the entire procedure so that you have at least three trials for each detergent. .

Conclusion

My hypothesis was incorrect because all of the worms died even when exposed to a "green" detergent. Based on the data the highest amount of alive worms recorded was in the control (with no detergent) at 4 and all the detergent concentration groups tied for the least amount of alive worms at 0. From my results, I thought it was very interesting that all of the detergents had simular effects dispite the different brands. The data suggests that no matter what the concentration is of "green" or regular detergent they all have a termendous effect on worms. I may have had a bad batch of worms that caused them to die easier or couls have possibly put in more concentration then needed. However, this data suggests that people must be aware of what is entering the enviromentnt because no matter how much or how little is entering a habitat or ecosystem it could have a huge effect on not only a spieces, but many down the road.
