Milkweed Bug Experiment Lab Report

The pill bugs were cuddling with each other as a way to preserve the heat and therefore, wouldn’t waist a lot of energy and eventually die. For the 24 C the bugs where moving at a full speed. As it is said that the pill bugs are well adapted to moist temperatures because they need it as a way to breathe and not die from dehydration. Pill bugs tend to come out during the day because of the moist. The results are compatible with the results of the group experiments. The mean for the bill bugs was higher with an 11.6 for times turned 25 C, the lowest was 3.6 for 35 C. This gives us an idea of what temperature the pill bugs like the most and which one they survive the best.

The overall purpose of this investigation was to determine the effects of different types of environments on pill bug attractancy. Pill bugs were exposed to 2 different environments (sugar and water). The attractancy was observed and recorded in a raw data table. A research hypothesis was formulated that the sugar would work as the best attractant for pill bugs. Sugar had the greatest impact of the two environments used because it attracted 8/9 ants. Due to this the research hypothesis was supported. After further calculations if a person wanted to collect 64 pill bugs all he/she needs to do is spray this mixture of sugar around his house and everywhere in his backyard.

The hands were washed. Goggles were placed on the eyes for extra protection. A petri dish containing nine pill bugs were obtained and set aside for later use. Two water bottles’ ends were cut and taped to each other creating a miniature tunnel for the pill bugs to crawl in. 50 mL of tap water was obtained in a small beaker and then was slowly moved into the lid of the bottle using a funnel. The sugar used in this experiment was created by mixing ten milliliters of starch,glucose, and regular countertop sugar. This was transferred into the joint water bottle tunnel using a funnel. Both ends of the tunnel were sealed shut and each measurements were taken every three minutes and final measurements were taken after 21 minutes. The results were

Next time I would not add air bubbles into the dish once the brine shrimp eggs were added in but before we put the eggs in the water. I would do this to prevent eggs from being moved from one dish to another or sucking eggs out of the dishes. When recreating the lab, I would take precautions to ensure the outcome would be as accurate as possible. These precautions would keep the data from being inaccurate. Before starting the lab I would make sure variables and controls were well defined.

If a lake is cut from the ocean and has no large fish as predators (only dragonflies), then the sticklebacks will have a better chance at surviving and reproducing because the sticklebacks will be better adapted to the environment (presence/absence of a pelvic bone) and have little to no predators. The hypothesis was supported. Before the experiment started, background knowledge was collected to better the knowledge of the lakes. Bear Paw Lake is an enclosed lake, meaning no predators could get into the lake.

In Milkweed, by Jerry Spinelli the main conflict is person vs. person. Throughout the story, Misha has an external conflict with the jackboots. Misha never really understands the actual external conflict here: it is between himself and the Nazi party. Misha, being given a Jewish identity, is in trouble (despite how happy he is about his "birth"). Misha's life is always in jeopardy, even if he doesn't know this. Even at the beginning of the story the town is under attack (and Uri saves Misha). Later, Misha elects to move into the Warsaw ghetto with Janina's family, again, not knowing that the Nazis are his real enemy.

• N. Dirilgen, 1994, Cobalt-copper and Cobalt-zinc effects on duckweed growth and metal accumulation. Different concentrations of Cobalt2+, Zinc2+ and Copper2+ as well as Co2+Cu2+ and Co2+Zn2+ were added to nutrients given to a species of duckweed, Lemna minor L. the effects of these metals on the growth of the duckweed was recorded. A change in growth was not very noticeable until the concentration of Cobalt (Co) and Copper (Cu) reached 2.00 ppm (parts per million), where the growth of the duckweed was inhibited. It was also discovered that Cu and Co work together to inhibit growth when they are at a certain concentration, and at other concentrations, the one would neutralise the other, creating less of an effect on the growth of the duckweed. The conclusion the I took from this study is that as the

However, our experiment was to test if the amount of water used to water each crop was unnecessary. We watered a group of plants with the average amount of water used in farms, watered a group of plants with a little less than average, and watered a group of plants with a small amount of water. We normally watered the plants with the average amount until all of the plants germinated. After the plants germinated, we started our experiment and controlled the amount of water. After about two weeks our experiment was over.

First test, Morphological of Unknown consists of multiple of subtests. First subtest was used to determine the optimum temperature of unknown #398 growth by inoculation into 2 nutrient agar slants.

Part I Assembly of respirometers: 1. A total of 4 respirometers were set up. The respirometers are numbered 1, 2, 3 and 4. 2. Germinating seeds are placed in Respirometer 1, fresh seeds and beads are in Respirometer 2, dry seeds and beads in respirometer 3 and beads alone are placed in Respirometer 4.

In this experiment, Pill bugs were exposed to different environments within a closed space and observed to determine which environment they preferred. The four different environments tested consisted of flowers, dirt, grass, and an empty space. Ten pill bugs were placed within the shoe box and observed for a total of 15 minutes to determine what environment the bugs preferred. The independent variables were the different conditions in each section of the shoe box, while the dependent variable was the behavior the pill bugs displayed. Throughout the experiment, the control variable was the empty section of the shoe box. By the end of the experiment, it became clear that the pill bugs preferred the environment consisting of dirt over the other

Misha Milgrom, also known as Misha Pilsudski and Stop Thief, is a character from the book Milkweed. He is the protagonist in Milkweed. At first, Misha is an unnamed boy until he meets a band of thieves, where his thieve friend Uri gives him his name. Liesel Meminger, daughter to Rosa and Hans Hubermann, is the protagonist in The book Thief. Liesel, a book lover, is the book thief herself. Many differences and similarities can be found between these two characters. However, Misha and Liesel are more different than they are alike.

The Sneezeweed is best suited for boarders in gardens. Because of the height the Sneezeweed can reach and the form of the stems it is best to use this plant in a large massing. Although Sneezeweeds have a beautiful flower using this plant in a boarder; the plant does not have the charactristics to be used a functional focal point. The Sneezeweed is also good for naturalistic settings. It can be used in prairies, meadows, naturalized areas, or along water.
