Abstract

The experiment is designed to determine which substrate, A (oat bran) or B (peat moss) will be better nourishment for a mealworm after exposed for 7 days. A total of 30 mealworms were placed in the substrates for a period of 7 days; 15 in substrate A and 15 in substrate B. The data was compiled and analyzed on day 7 to determine the change of mass in each of the mealworms. The experiment proved my hypothesis to be correct; the mealworms would not thrive in either substrate.

Introduction

Using the scientific method, it is necessary to obtain some information about mealworms and each of the substrates. Mealworms, also known as Tenebrio molitor, live in areas surrounded by what they eat under rocks, logs, in animal burrows and stored grains. These are dark, cool and moist places. (The University of Arizona, 1997) The ideal temperature to maintain growth in the mealworm is 77-81 degrees Fahrenheit. Temperatures above 86 degrees Fahrenheit negatively impact growth and development of the mealworm. (Burdett, 2010)The purpose of the experiment is to observe how substrate A or substrate B will impact the growth of the larvae. Oat bran is the outer husk of the oat grain. It contains the bulk of the dietary fiber of the grain, along with a large amount of useful materials. (Smith) Peat moss is decomposing, dead parts of sphagam moss that usually are found deep in a bog. It is rich in organic matter, and typically can hold up to 20 times its dry weight in water. (Gordon) My hypothesis is the mealworms would not thrive in either substrate due to the temperature they are being stored.

Materials and Methods

In this experiment, 30 mealworms were weighed and their mass was recorded. Then 15 were put in substrate A and 15 were put into substrate B to test which would make the mealworm grow bigger and faster. Each mealworm was placed in a plastic vial with either substrate A or B and we used a graduated 1 ml pipette

    The experiment that I decided to look into, was finding out if an Armadillidium vulgar, also known as a pill bug, would have a preference to the two types of environments that I had decided to experiment with. The two types of habitats that I choose were saran wrap which is smooth and sandpaper that is rough. How I set up this test was I had a choice chamber with a barrier in the middle that had a little door cut out of the bottom center so the pill bugs could walk through. I placed sandpaper on the bottom of one side and saran wrap on the bottom of the other side. After placing the pill bugs into the chamber I observed them for 10 minutes taking notes on their activity every…

Note: Your predictions will not be evaluated—this is called making a HYPOTHESIS (an educated guess). Proving or disproving hypotheses is how important scientific discoveries are made.

    Introduction – This section should include an overview of why the experiment was conducted. It should first contain background information of similar studies that have already been done in the area. This is accomplished by citing existing literature from similar experiments along with explaining their results. Secondly, it should provide an objective or a reason why the experiment is being done. Why do we want to know the answer to the question we are asking? Finally, it should end with a hypothesis. You should pose a question and predict the answer to the question that will be investigated. This hypothesis should be made prior to your experiment and should not be adjusted to reflect the “right”…

    The aim of this investigation is to find a correlation between the number of maggots in the mass and the temperature of maggot mass. To find the correlation the different number of maggots in each mass was placed in (the isolated by glass beakers) polystyrene cups. The internal temperature of masses was obtained regularly every 10 minutes during 30 minutes time period under the same temperature of surroundings. The experiment was repeated several times and all results were recorded, averages were calculated and the graph showing the correlation was plotted. The result of the investigation is a positive correlation between the number of maggots in the mass and the temperature of the mass (the more maggots there are in mass the higher is the internal temperature of it). Then maggots were allowed to pupate and the time taken for every mass of maggots to pupate (until all larvae in the mass are pupated) was determined. This allowed us to conclude that the number of maggots in the mass and the development time has a negative correlation (as the number of maggots in mass the less time it takes them to pupate), which proved that the prediction and hypothesis made before the experiment was conducted were right. The results of the experiment showed that the number of maggots in the does affect the time for maggots to develop. The research was done to explain the results.…

    During our groups controlled experiment we measured the masses of the soil, plant, and the water we put in the plant. We put 100ml full in each cup when watered. We put a table that compared the change in initial and final in weight (grams). For our dependent variable, we put each plant in different cups. For independent variable we measured the mass of the plant, cup, and soil in grams.…

    Worms Vs. Dry Creatures

    The worms chose the wet side of the paper towels rather than the dry side because the prefer moist places. This statement becomes clear when the data of the two trials is looked over. The data proves that mealworms prefer the wet side of the paper towel. Research says that mealworms prefer moist, dark places, and that cold stunts their growth. When the mealworms were taken out of the fridge, the larvae were slow to get moving. This is why the data for trial one is so scattered around. But by trial two the worms were all warmed up and active so the larvae were a lot quicker to get to where they wanted to go. That is why the data in trial two isn’t very scattered but trial one is very scattered. During the lab it took longer for the worms to…
