Introduction:In our group, we decided to an experiment

that required worms and drugs. We decided to use Tylenol and Advil as our drugs for this experiment. Both Advil and Tylenol are pain killers. If one or the other is taken too much it can damage the health of our bodies, but they are both addicting to people and then people rely on them. When they become more reliable on them they tend to take more and will cause negative effects on the human body. Some of the effects that happens is loss of appetite, hallucinations, swellings, etc. Earthworms are from a group of Annelida. They are one of the most type in Annelida. Earthworms live in most environment and feed on a wide range of materials.Question:

If drugs were added to the soil that the earthworms are in, which group of worms will go the farthest distance?Hypothesis: We predicted that the worms with no drugs would go the farthest because their was no chemical added to the sand.

Method:

First we measured ½ cup of water and put it into a container(repeat 2 more times). Then we put 8 Advil into one of the containers and 8 Tylenol into the other container. We left one container with water only. Then we got soil and three other containers with nothing inside of it. We put cup of containers into the three empty containers. After that we put the water that had the pills dissolved into the containers. Then we added 12 worms into each of the three containers and waited 30 minutes. After 30 minutes had passed we got all the worms and measured the distance that they went in 1 minute.

Four of the same group of worms being timed.

Worms bunched up together…

This is us working on the experiment.

Materials:

Tylenol, Advil, water, containers, 36 worms, measuring cup, ruler, timer, and soil.

Summary:Based on our experiment, the worms that

had no pills were the fastest. So our hypothesis was proven right because we predicted that the normal worms(worms with no drugs) would be the fastest. The average distance for Advil’s group was zero centimeters, Tylenol’s group was about 0.6 centimeters, and for the normal group, it was about 2.4 centimeters. Discussion:

We believe that the worms that were with drugs are slower, because the worms that had been involved with a chemical that they weren’t used to. The worms that were in the drugged soil were not happy to be in it and were panicking to get out. As time went by they startled to get tired and stopped moving. Mean while the worms that were in the normal sand settled in the soil calmly. The difference between the normal and drugged worms were very different yet not, because some of the result were the same and others were different by a lot.

This showed us that worms would never get addicted to Tylenol and Advil like how some humans do.

Thanks to:Our science teacher Mrs. Hubner, our computer teacher Mrs. Stambach, and finally Target for helping with our trip to UC Davis.

Results:There were different ranges of results in our experiment. All of Advil’s result were 0 cm and all of Tylenol’s results were in between 0 to 2. the worms with no drugs were in the ranges of 0 to 5. so this means that even if there were some similar results, the averages of the results. would be very different.
