    experiments making their own observations before providing them with information and details. This allowed them to make personal connections with what they learned from me to what they observed with their earthworms. • Which parts worked and which didn’t? Why? How does this impact your next lesson? I feel like this was a successful lesson. Every piece tied into another piece, creating a cohesive lesson.…

  • Comparative Sensory Physiology Lab Report

    and chemicals. When these receptor cells are stimulated a nerve impulse is sent across the body and into the central nervous system where the signal is perceived as one of the animals senses (taste, hearing, sight, smell, equilibrium, etc.). There are three different types of receptors: electromagnetic receptors, mechanoreceptors, and chemoreceptors. In this lab we tested the mechanoreceptors and the electromagnetic (photo) receptors in an earthworm. To test the mechanoreceptors we separated…

  • Nitrate And Phosphate Level Lab Report

    relates to my hypothesis since it proves that the epigeic earthworms in the soil increased the nutrients in the soil, since the average nitrate and phosphate levels increased from tests 1-3. The results from this experiment showed that the control group increased their phosphate levels more so than the experimental groups, which contained the red wriggler earthworms. This could have been due to high amounts of Ca²⁺ in the water, leading to the Phosphate binding to Calcium, which would have led…

    paramount importance when it comes to planting crops. A major factor attributed to soil quality is the presence of earthworms. Earthworms are very important in the world of agriculture and can help maximize crop yields. In this study, the effects of earthworms on varying soil pHs and soil density were viewed. Earthworms (Lumbricus terrestris) are very beneficial for the soil. They change the structure and composition of the soil, they alter water movement, alter the nutrients in soil, and help…

  • Earthworm Invasions

    Earthworm invasion in previously earthworm free regions (e.g., glaciated northern part of North America and Europe) has become a conservation threat to rare native species, community, and ecosystems (Gundale 2002; Hale et al. 2006; Nuzzo et al 2009; Maerz et al. 2009; Sutherland et al. 2011; Nuzzo et al. 2015). In 2011, Sunderland and coauthors identified earthworm invasions in previously earthworm free regions as one of the 15 most immerging issues of biodiversity conservation. One of the…

    Earthworm Action Potential Conduction Velocity: The Effects of Various Salts and Neurotransmitters When it comes to performing action potential experiments within the lab, the giant nerve fibers of an earthworm are an important tool for success. They yield a high success rate when compared to other organisms (Kladt, Hanslik, & Heinzel, 2010), and provide a more ethical means of testing how various neurotransmitters affect action potentials, instead of direct use on humans for pharmaceutical…

    3. The earthworm has a segmented body with a mouth at the anterior end and an anus at the posterior end. It has a smooth, purple dorsal side and a rough, yellow ventral side with setae. Two sperm grooves run along the body from segment 15 (where sperm ducts are also located) to the clitellum, which looks like a tube surrounding the earthworm’s body and is closer to the anterior end. 4. The setae are likely on the outside of the body for more effective locomotion. They allow the earthworm to…

  • Essay On Earthworm Worms

    Soil preference of the Red Compost Worms, Eisenia fetida INTRODUCTION Earthworms provide countless benefits to humans, plants and animals, by improving drainage, advancing nutrient accessibility, and providing a steady soil system, helping to develop farm production. They benefit the soil ecosystem by decomposing and recycling organic matter, opening up pores inside the soil to develop its formation and supplying food for predators . By adding nutrients to the soil they inhabit, earthworms are…

  • Intestine In Earthworm Research Paper

    Discussion: 1. Compare the ratio of the lengths of the intestine in earthworms, frogs, pigs, and humans. What significance do the lengths have with respect to the organism? Based on dissection, it was noted that the length of the intestine in earthworms, frogs, and humans all vary in sizes. The intestine of the earthworm is about two-thirds of the worm 's body length. The length of the small intestine of the frog is 3 feet while its large intestine is about 1 feet. A pig 's small intestine…
