I will plant 3 bean seeds in two pots, one with worms the other without, and collect data to determine if the worms make a difference in the growth of the plants. The effects of worms on plant growth. In this experiment I will try to determine if worms in the soil of plants will help them grow. This will be useful to farmers and families that grow their own food. If worms do help plants to grow then by introducing them into the soil they will increase the amount of food produced. Purpose If there are worms in the soil of plants then the plants will grow faster and taller. Worms waste or castings provide needed nutrients for plants and their burrows provide a place for roots to grow. Hypothesis I will use two pots of equal size with equal amounts of soil in each.
Worms will be placed into the soil of one of the pots. Three bean seeds
Will be placed into each pot and watered with equal amounts of water.
The pots will be placed in a warm sunny location and watered with equal
Amounts of water as needed. Data will be collected as to the rate of
Growth of the plants in each pot and recorded in a chart. Experimental design Two plastic pots
White half runner green bean seeds
Graduated cylinder Materials The independent variable is the presence of worms in the soil. The dependent variable is the height of the plants after 14 days. To determine this the plants will be measured with a ruler each day and then averaging the heights of the plants with worms and without worms. The constant variables are the size of the pots, type of seeds, sunlight, temperature, light, etc.
The pots are labeled with worms and no worms. The pots are filled with equal amounts of soil and the worms placed into the pot labeled with worms. The seeds are planted and covered with 1cm of the soil.
The plants are watered and placed in a well lit warm location. The plants will receive equal amounts of water every other day.
Measurements will be taken each day after the plants emerge and the date will be recorded in a chart. Procedure day 1-7 day 8 day 9 day 10 day 11 day 12 day 13 day 14 day 15 Plant 1 with worms no growth 6 18 23 27.5 29.5 31 36 40 Plant 2 with worms no growth 4 17 21 25.5 26 26 27 31 Plant 3 with worms no growth 0 409 17 20.5 23 26.5 30 36 Average of 3 plants with worms on last day 35.7 Plant 4 no worms no growth 3 14.5 20.5 24.5 26 28.5 33 36.5 Plant 5 no worms no growth 0 10 14.5 19 21.5 25 26 28 Plant 6 no worms no growth 0 2 4 6.5 7.5 9.5 15 21 Average of 3 plants without worms on last day 28.5 Data Table Data Graph The seeds planted with worms in the pot emerged quicker, grew at a faster rate and grew taller than those without worms. The plants were measured each day after they emerged and these results were entered into a chart. This data was put on a bar graph and compared. Only one plant without worms grew taller than two of those with worms. This shows that worms in the soil of plants did grow better than those without worms. Worms give vital nutrients to the plants and also make burrows which provide a place for roots to grow. Results In this experiment it was show that worms are beneficial to the growth of plants. After planting the same type of seeds into two like pots, one with worms one without worm, the plants were watered with equal amounts of water and placed in a warm sunlit location. The plants were measured each day after they emerged and this data was recorded. The data was compared and showed that worms did cause the plants to emerge quicker, grow faster and taller. Conclusion As you can see from the data my original hypothesis was correct. If there are worms in the soil of plants then they will grow faster and taller. Further experimentation can be done with different types of seeds, worms, and soil. You could also try putting worms into the soil of already grown plants and see if there is any difference in continued growth. Conclusion pg2 Source #1
