Isopod Lab

Introduction:
This lab is used to see if and how many of the Isopods like the light or the dark. Isopods also known as pill-bugs, roll into a ball when felt threatened. Isopods are very similar in body types as lobster, crabs, and shrimp. They all have compound eyes and antennae, but still sometimes do not always look alike. Isopods can be as long as 500 millimeters and can live as long as 4 years. Their body has 3 part; the head, thorax, and abdomen. They are often caught from the wild. Due to being caught in the wild, Isopods are often found living under rocks, logs, leaves, lakes, rivers, and streams. Isopods can hermaphroditic which is being both girl and guy, meaning they do not need a mate to produce offspring. Isopods can be born a male then change to a female later on in life. Isopods eat fungi and decaying plant matter.
Experimental Design:
Testable Question: How will the isopods react to different lighting conditions?
Independent Variable: Lighting condition
Dependent Variable: How the isopods will react
Test:
Materials:
Scotch Blue Tape
8 ounce water …show more content…

Based on the data, it was learned that the isopods do not appear that they differentiate between light and dark. After conducting the experiment new questions arose; Is there a maximum period of time the isopods can be in the light and dark?, and Does the type of light have an effect on where the isopods prefer to be? Some improvements that could be made are more isopods, bigger testing chambers, better means of darkness, and a less and more intense light. Another improvement that could be made is test different intensities of darkness and lightness. There were no apparent weaknesses in the experimental design. In conclusion, the isopods appear to not be sensitive to the light or the

The purpose of the lab is to acquire the percent composition of zinc and copper. The procedure included obtaining a post 1983 penny and washing it with soap and water. Using a triangular file, we made an X on the penny. Then, we cleaned the top and bottom of the penny with steel wool until it was shiny. We rinsed the penny in acetone and dried it with paper towel.

This adaptation is to retain moisture using a special structure – the operculum – which can be sealed when the snail is not eating to retain moisture within the shell. This is used especially between the high tides, as water only reaches this high zone at these times. Another factor associated with the supralittoral zone is harsh wind conditions, which was observed at Hastings Point where the temperature indicated a 12% increase in average temperature between the littoral and supralittoral zones. The black nerites adapted behaviourally to survive these conditions. To do this,

Also, they like to eat Detritus and it is a more acidic plant (Animal Behavior: Pillbugs and Their Preferences, 2003-2015). This being said, would isopods refer to be in an area with low pH, high pH or water? I there is a low pH, high pH, or water, then the isopods would prefer the water because most organisms are sensitive to certain pH levels.

Once acclimated, the isopods walked around the arena for five minutes and go to the sponges that they preferred. The experiments should be repeated 3 times with the same design layout for accurate results. 20 isopods were released in the center of the arena. After five minutes, the number of isopods behind every sponge was

In our experiment, we examined the behavior of isopods by conducting the experiment based on our hypothesis: “If ten isopods are put into the test chamber, 5 in sand and 5 in soil, which environment will the pillbug prefer.” We hypothesized that the isopods would favor the soil more than the sand because pillbugs are typically found in soil and not in sand. Pillbugs are favored in soil because the natural role of a pillbug is to eat dead and decaying things but, in sand there are no nutrients available for pillbugs. Pill bugs are mostly found in moist environments, due to having gills, gills only function when they are wet so pill bugs will inhabit places in which air holds a lot of water

We placed three female bean beetles and two male bean beetles in each petri dish. We had a total of three petri dishes, one for each trial. The petri dishes were then placed in constant light under the same conditions for a week. After one week, the data was then collected by counting the number of eggs on each bean by using a light microscope and this number was then recorded and compared to each bean

Abstract: The main focus of this lab is on animal behaviors in terrestial isopods, also known as pillbugs. There are many purposes to this lab experiment. First, these pillbugs are put into four different types of enviroments, also known as chambers, light v. dark, hot vs. cold, moisture vs. dry, and lastly shelter vs. open. In these different chambers, there are 10 pillbugs, 5 placed into each individual chamber and then observed for up to 5 – 10 minutes. In this lab we observed that pillbugs prefer light areas, hot temperatures, moist environments, and lastly sheltered spaces.

Results- This graph shows the amount of time spent in the these areas. This tiny sowbug did much of its time in the light portion of this experiment. The tiny sowbug did the most traveling back and forth from the light and dark areas of the trays. This graph shows the amount of time spent in the areas of light and dark.

Intro People expect their government to have their best interest in mind and always protect its citizens, but what about when it doesn’t? There are dozens are possibly hundreds of shady events that our government covers up. People believe that the government is hiding aliens, technology capable of time travel, and even Walt Disney’s head frozen in cryostat. Yet for now those are simply just conspiracies.

Because carbon dioxide is absorbed by the plant during photosynthesis less carbon dioxide present in the chamber is a sign that photosynthesis is working. The four lights used for this experiment range across the light spectrum on both sides in order to test a wider variety of wavelengths. All lights will be placed directly on the spinach leaf at the same distance so as not to give any spinach leaf a different light intensity, which could affect the data. This experiment will be able to show which light, ranging across the light spectrum, will allow the Spinach to perform photosynthesis more efficiently.

This laboratory experiment involving invertebrates is conducted to enable students to investigate Daphnia magna’s responses to external stimuli, therefore developing a better understanding and knowledge of homeostasis that occurs in organisms and the reaction and behavior exhibited by the daphnia magna when varying conditions are exposed to the organism compared to its natural environment conditions (Carter-Edwards et al, 2011). In order to understand the experiment, a foundation of information about the chosen organism such as its natural environment and physiology must be understood. According to Clare (2002) and Ebert (2005), Daphnia magna are small planktonic crustaceans belonging to the subclass Phyllopoda, found in lakes and

As above the name of the organization I chose to research is Aim High. This organization is located in seven different cities, mostly concentrating in Northern California. Out of those seven cities, it operates in seventeen different places. The organization helps low-income students and it contributes to the local communities by providing the students learning and academic experiences so they can be successful in their future studies. Their mission is to “nurture the promise and potential of middle school students from low-income neighborhoods, prepare students for high school, setting them on the path to college and future success, and inspire the next generation of teachers and educational leaders” (Aim High, n.d.).

Also, a few sponge species that live in food-poor environments turn carnivores that prey mainly on small crustaceans. Reproduction and life cycle: Most sponges are hermaphroditic (having both sexes in one), but at any given time, a sponge animal plays the male role and release sperm while the other partner plays the female role. In subsequent reproduction, they may change the sexual roles. Sponges have no gonads and so the sperm and/or eggs are produced through specific arrangements.
