Paper Worm Lab Results

BEFORE CONDUCTING THE EXPERIMENT - You should already have submitted to your teacher an EXCELLENT Investigation Design that included:

The purpose of this lab was to save a little gummy worm named Sam from drowning. In addition, one of the labs key terms was a hypothesis which is a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation. Furthermore, we also learned that an independent variable is a factor that is changed during the experiment. On the other hand, the dependent variable is the factor that is observed or measured during the experiment. To begin with, the experiment the hypothesis formulated was if we reshape the paperclips into hooks and pick up sam, and the lifesaver (without touching them), then the lifesaver would be stretched enough for Sam to go through it.

The purpose of this experiment is to determine which stimuli sowbugs prefer more, moist or dark. However, to confirm that sowbugs prefer dark and moist environments we had to create an experiment to prove this. We proved sowbugs prefer dark environments by using a lamp to create a light environment and cardboard over half the petri dish to create the dark environment; the sowbugs chose the dark side. Then we proved sowbugs preferred moist environments over dry ones by creating a wet environment on one side and a dry environment on the other side of the petri dish. After our final experiment, we were able to determine that sowbugs prefer the dark stimuli over moist stimuli.

Introduction Black worms are fun little critters that show us exactly what a simple vascular system looks like, one vein with a head and tail and a slow enough pulse to easily count. Their skin is translucent, so with only a compound microscope you can view the insides of the small worm. Another great quality is that the diffusion of a drug into the worms system is a quick process (Bohrer, 2006). The purpose of this experiment is to see the effect of alcohol on the vascular system of the Lumbriculus Variegatus. My hypothesis was that If Alcohol is exposed to the Black worm them the pulse rate would decrease because to humans alcohol is a depressant.

Abstract: This experiment was exploring our curiosity of sowbugs and their preferences. Our main question was about how the sowbugs natural diet can affect their preference for sodium chloride also known as table salt and glucose which is also known as sugar. The experiment involved testing how much time each sowbug spent in each substance when in a tray with both salt and sugar on opposite sides.

In this experiment, contractions of the earthworm gut are measured in an organ bath with a force transducer. The effect of neurotransmitters and ionic concentrations on contraction strength and rate will be investigated.

2. Throughout the three trials, the bugs seemed to either all be moving or not moving at one time. Some bugs climbed on top of each other or rode on each other’s backs. There were a few bugs that played dead. For example, one bug laid on its back while not moving for almost the entire lab. The bugs typically liked to stay near each other. For example, in the wet and dry test, at one point, all of the bugs were clumped on the far side of the dry chamber.

I love gummy worms I been in a gummy worm factory I fell in love with it just the flavors and sweet texture just grab my attention not in that way. I use to buy gummy bears a lot everyday I had a little bit of a sweet tooth my mom just always buy me some gummies at dollar the store. It's kinda funny how i just always on my birthday my mom would ask me what i want for my birthday I would just say money and gummy worms. My mom would just be cool with it she really didn't even care she wasn't buying expensive things that's why.

Purpose: We want to see if putting a worm or organism in different temperature will change the rate of CO2. We predict cold will make the process slow down. Hot will speed it up, and with room

Genetics is the study of genes, heredity and variation in living organism. It is important in understanding how heritable traits are passed down from one generation to another. Here in this study, the identification of a particular mutation was explored by discovering how it is transmitted and where it is located. Drosophila melanogaster, a species of fruit flies, was the model used to illustrate the process of gene inheritance. Virgin female fruit flies were collected over a span of two- three weeks and crossed with balancer chromosome male fruit flies. The progeny, also known as the F1 generation, was then used to perform a test cross. The test cross was done between an F1 male and a virgin female from the parental generation. The results of the test cross, determined the mutation as well as which chromosome it was located on.

Fruit Fly experiment was conducted by using different techniques. One of the main things was to examine the fruit flies and identify the difference between females and males, identify their mutation if they were wild type, white eye, vestigial or white and vestigial combined together. These Fruit flies were kept in the incubator at 25°C for about 6 days. The main goal for this experiment was to observe the principles of Mendelian genetics.

___IV. Practical Aspects - This book provides detailed descriptions on tests including specific data for purpose

After a few months, an outbreak of cotton worm occurs on Epps plantation, incapable of working his fields, he loans his slaves to a nearby plantation for the season. While there, Judge Turner gives Northup the opportunity to play the fiddle at a neighbor’s anniversary celebration, and he is able to keep his earnings from it. When the slaves return to Epps plantation, Northup attempts to use the money to pay a white field hand, Armsby, to mail a letter to New York for him. Armsby agrees to send the letter, and takes Northup’s saved money in return, but later betrays him by telling Epps about it. Northup ends up convincing Epps that Armby is lying and avoids being punished.

The hypothesis was supported because the density of soils with the presence of earthworms had decreased and the pH of the soil changed, becoming increasingly neutral. It was hypothesized that if earthworms are placed into a container of soil, then the pH of the soil will become increasingly neutral and the density of the soil will decrease because the digestive tracts in the worm produce molecules that are natural buffers and because worms aerate the soil, leaving pockets of air in the soil, increasing the volume of the soil. The tests on soil pH showed that the pH of the soils in both positive and negative controls, which started at a pH of 7 remained at 7, while the pH levels of the 6 pH increased to 7 (see Figures 7 and 8) and the pH of

The purpose of this experiment is to test how location affects whether or not the clay caterpillar models will get pecked by birds. Twenty-one clay caterpillars were made and they were made to be 5 cm ± 0.01cm long and 1 cm ± 0.01cm in diameter. Seven caterpillar models were placed in each of the three locations. The three locations are my backyard, the park, and my community garden. As a control variable, all the caterpillars were placed 300 cm ± 50 cm above the ground. An equal amount of caterpillars were glued, to prevent them falling off, in similar areas such as trees, bushes, and fences. This experiment went on for three weeks. Each week is considered one trial. Each caterpillar that was pecked or not was recorded and the data was placed
