The Effect Of Different Distance Intensities Of Light On Terrestrial Isopods:
Hypothesis (Null): There will be no effect upon different distance intensities of light on the terrestrial isopods.

IV: The different distance intensities of light at specified lengths (1 meter, 2 meter, and 3 meters) DV: The number of terrestrial isopods (rolypolies) on the unlighted side on the petri dish.

Control: The unlighted side of the opened up petri dish.

Purpose: To determine the light sensitivity of terrestrial isopods (rolypolies) in different levels of lighted environment.

Number of Trials: Three 30, 60, and 90 second trials for each specified level of light at 1, 2, and 3 meters distance.

Constants: The temperature of the room, petri dish, time trials for each trial of light distance testing, and the number of trials.

Materials: Clear petri dish, one projector with bulb pre-inserted and rolling cart, piece of aluminum foil.

Procedure: To start the project the first thing to do is locate and transfer about ten terrestrial isopods (rolypolies) on each side of a petri dish with five rolypolies on each side. On the control side of the opened up petri dish, it will be unlighted due to a piece of aluminum foil wrapped around that area. On the other side of the opened up petri dish, it will lighted with varying distance intensity due to the movement of the projector to 1 meter, 2 meter, and 3 meter lengths. Each trial will last a total of 90 seconds long and will be duplicated three times at 3-30, 60, 90 second intervals for each varying distance intensity of light distance. After the trials, the data collected from the movements of the rolypolies which will indicate the effect of varying distance intensities of light on the test subjects or terrestrial isopods.

Data: On the x-axis, the time will be set in 10 second intervals for a total of nine intervals. The number of rolypolies on each side of the petri dish at any given time will be on the y-axis. There will be two separate colored (i.e. green and blue) lines for each varying distance intensity

    As we see in table one, our results show that brine shrimps prefer the dark as appose to the light. The shrimps started out by being in the light at first but gradually all the shrimps moved to the dark side. In the wild brine shrimps prefer the light as they are found in the shallow part of the ocean rather than the deep dark side (Brine Shrimp, 2016). Our results do not make sense as we saw that our shrimp went to the dark side rather than the light side, as in the wild they are usually sound in the light side.…

    As expected, the control group had a feeding rate between that of the higher and lower light intensities. Buikema (1973) mentions that light intensities that exceed a certain threshold tend to suppress the filtering rate. We theorized that their feeding rate increased in the dark environment because it reflects their natural habitat. Populations of D. magna perform diel vertical migration, which means that they only spend the night in surface layers of the water and migrate downwards into the lower water layers during the day (Dodson, 1990; Haney, 1985). The ultimate cause for this is to protect themselves from predators. The proximal cause is the change in light intensity. D. magna present with photosensitive behaviour and they tend to move into areas of low light (Dodson, 1990). Young et al. (1984) report a decrease in the rate of limb beating when exposed to increased light intensity. The rate of limb beating directly affects the rate of filtration. If there is a decrease in the rate of limb beating then the feeding rate will also…

    In which, both the chi-squared test and the observation of the pillbugs appears to prefer the moist chamber than the dry chamber. The possible errors associated with this experiment include, the isopods climbing over each other. At times it would block the connecting chambers preventing the flow between the chambers. In addition, the rocks used in this experiment were slightly moist and may have affected the experiment. Some further investigation include increasing the test size, testing whether isopods prefer light or dark and the pH the isopods…

    The aim of this investigation was to determine which component wavelength of light functioned best in a brine shrimp’s phototaxic and photokinetic responses. It was hypothesised that the brine shrimp would display a heightened positive phototaxic response, and that a more pronounced photokinetic response (increased velocity) would be observed when the samples were exposed to green light. Artemia salina (common name: Brine Shrimp), are from the order Anostraca of the class Crustacea. Adult brine shrimp are around 10-30mm in length, they “consist of a long cylindrical body divided into a head, a thorax with many pairs of foliaceous limbs and the genitalia, and an abdomen.”…

    In plants that contain chlorophyll, the photosynthesis process splits H20, releasing oxygen, and storing the produced energy resulting from the chemical reaction inside a carbohydrate molecule. This is shown in the following equation for photosynthesis: Water + Carbon Dioxide (with the aid of chlorophyll and light energy)  Glucose + Oxygen (Matthews & Lindbeck, 2013). In addition, the rate of photosynthesis has varying factors, which among them include the amount of carbon dioxide present, the light intensity, and the type of organism. In this experiment, our aim was to investigate how the amount of light intensity affects…

    Determining the Effect of Light Intensity on Photosynthesis Avalon Pernell, et al Abstract: The purpose of this lab was to determine how light affected photosynthesis, specifically the production of O2 bubbles. It was predicted that when the light was more intense the O2 bubble production will be high. Conversely, when the light was less intense the O2 bubble production will be lower.…

    The abiotic factor that we plan to investigate and study is the light intensity. The length of the photoperiod in a Gammarus setosus’s habitat is linked to them being able to successfully grow and reproduce (Steele & Steele, 1970). The Gammarus setosus contain modified cilia, which are the primary sensory receptors in several photoreceptors (Steele, 1986). There have also been studies that show that the reproductive cycle of a female Gammarus setosus can be faster or slowed down by the photoperiod (Steele, Steele, & MacPherson, 1977). Furthermore, there is also evidence that photoperiod has an influence on the timing of the reproductive cycle (Steele et al., 1977). The less exposure to a specific amount of photoperiod (light) leads to an increase…
