Mealworm Lab Report

Once upon a time in a lab far far away there was a very curious young scientist named James. James is a very young man who one day stumbled upon a new subject flatworms. He found early in his research that they can be very dangerous but on the other hand can help the earth. When he went into his lab early one morning he discovered that the worm had many segments so he tried an experiment if on piece of flatworm can regenerate into an entirely new form of flatworm. His experiment was a smashing success. He was a very known scientist all around his house. He was very excited and had just found a groundbreaking discovery for flatworms.

Abstract: The experiment is designed to show which substrate A or B will better nourish a mealworm. A mealworm was placed in each substrate for a period of seven days and the change in mass from Day 1 to Day 7 was compared. The data was compiled and statistically analyzed. The experiment failed to reject the null hypotheses that there would be no difference in the two substrates regarding meal worm growth. The conclusion that there was a difference requires more experimentation to obtain additional information.

Students will label 3 test tubes hot, cold, and room temperature and place potato cub (3X3X3 cm)

The hypothesis was not supported by the data. When given 2g of cucumber, white potato, and carrot slices, the mealworms did not favor eating a cucumber in comparison to the other vegetables regardless of the higher content of water. While analyzing the data, it was found that the standard error bars of the cucumber data went from 1.85g to 1.89g and the white potato data went from 1.86g to 2.14g which meant that the true means of both of them overlap making that comparison and data statistically insignificant. Also, the white potato data’s true mean ranged from 1.86g to 2.14g and the carrot data’s true mean ranged from 1.91g to 2.03g, making that comparison also statistically insignificant. However, one thing that

The purpose of this lab was to use different methods of determining populations and to interpret the accuracy and precision of these methods. These methods were mark and recapture, quadrant count, and counting each individual worm in the habitat. Mark and recapture involving marking 25 worms with paint, putting them back in the habitat, capturing a new sample, and observing if they had marks while quadrant counting involved placing a sampling ring in random areas and counting how many worms were present. Neither of these methods were accurate in estimating the total population of mealworms. The results of the quadrant count are due to the clumped distribution of the organisms as shown by the ratio of the variance to the mean. Mark and recapture

A three week experiment was proposed. On week 1, the preparation of vials was the beginning of the experiment. An equal amount of food and water was measured and then mixed. This mixture was to be the food for the larvae. The mixture was placed in the vile with a height of 2-3 cm. The mixture had to be placed inside and made sure by pressure that no air pockets were

The purpose of this experiment was to see if worms could break down compost. The broken down compost could lead to less landfills. This would let civilizations prosper with the extra land, and improve everyday life significantly. The group provided the worms with compost so they could eat and break it down. The group also provided an enclosed area for the worms, where heat could collect and at the same time air could come in the compost. The air provided the worms with the molecules needed for cellular respiration, allowing them to create energy and break down the food. A water collection system was used at the bottom allowing access water to drain and not hurt the worms. The group hypothesized that if worms got certain resources(oxygen, compost,

The overall basic idea or theme of our lessons relating to the mealworms is "Animal Behaviors." This is an important concept for students to grasp because it can relate to many other things in

Two experimental errors that occurred during this experimentation were that the mealworms would find their way to move under the paper towels and the paper towels were not cut down to a size where there is a clear passageway in between the petri dishes. The paper towels were cut roughly to fit in each petri dishes, but it was a poor choice to make in hindsight. We had to constantly pick up the mealworms that had crawled under the paper towels with tweezers and that could’ve aleterd the final results. What could have also altered the final results was the fact that the paper towels were not cut in a specific way to allow any easy passageway for the mealworms to pass

Mealworms are highly used for protein for farm animals and household pets. Although it only takes about three weeks for the mealworm to reach its max peak, what if I could shorten that time? In my experiment, I am going to test to see which foods make a mealworm thrive fastest. I will have a combination of different foods that I feed them. Some examples are in one I will have wet and dry food, in others I may just have wet, and just dry in some. Mealworms main diet are grains and oats, this is what I will feed the control group. The other groups will have a combination of different foods. Each group will have ten mealworms and I will weigh them as a whole at the end of my experiment. What I hope to get out of this experiment is a faster way

Hookworms; also describe as the intestinal parasites are a serious infection that affects both humans and animals. The hookworms are very small species that develop based on blood-feeding. Those harmful species not only hook to the intestinal’ mucosa and suck the whole-body nutrition but also they conceal some antigens that cause a hold off to the immune resistance and eliminate the hemoglobin. As a result, the body undergo a series of intestinal hemorrhaging stats with extreme decrease in healthy blood cells. In other, the patient

The results of these two groups clearly differ from the other 4 groups. To exemplify, the results for the % change in mass of the groups 1, 2, 3 and 5 range from 6 – 11% but the results of group 4 and 6 are 34.09 % and 0.99 % respectively. One probable explanation for this discrepancy in the results is that the groups 4 and 6 may have conducted the experiment incorrectly. Potential factors that may have caused these inconsistencies in results, include a damaged weighing scale and a damaged timer, which could’ve misled the experimenters of groups 4 and 6 by displaying the incorrect time. This would mean that the potatoes were kept in the salt solution for more or less than 20 minutes, which would explain the vast difference in the

Materials: a raw beetroot, boiling tubes with stoppers x 14, boiling tube rack, distilled water, sucrose solutions (0.0M, 0.1M, 0.15M, 0.2M, 0.25M, 0.3M, 0.5M), cork borer, scalpel, pipette (±0,1ml), Pasteur pipette, ruler (0.1mm) and marker for writing on glass.

In the dissection of the earthworm three pins were used to hold it down. The first pin was at the anterior, the second at the posterior and the third was under the clitellum. Then the scalpel and blade were used to cut into the side of the dorsal vein of the earthworm. The dissecting probe was used to open up the worm and the used the pins to pin the sides down.

Considering this the Hornworm was kept under artificial light throughout the night and by a window through the day. The temperature was around 60-62 degrees Fahrenheit, which is typically too cold for the Hornworm. With that in consideration, we assumed the hornworm may possibly take more time to transition instars. The food source for the Tobacco Hornworm was what was provided which was a mixture of water, agar, and wheat germ.
