Bean Beetle Methods draft Writeup Would different beans, other then mug bean make the bean beetles produce less offspring. In this group project we conducted a hypothesis that argues, If using different beans for reproduction other then the mug bean, then they will produce less offspring. the dependent vearable is number of offspring and the independent veraible is the different type of beans. when conducting this experiements we used method of division, replication, and messureing. In this experiment, we devided each of the different beans. We used mug, black, and coffee beans. By placeing a plate for each bean, We where able dividing each the mug, black, and coffee beans into each plate. After dividing each bean we labled the name and group so we can better understand the difrence between the beans. The meathod of division is very simple and organized, alows to diffrentiate the difrence between each bean. The method of messuring, after deviding the rest of beans in the plates, we measured the weight of each plate of the mug, black, and coffee beans. we had a total of two plates each for the beans mug, black, and coffee beans. for the mug bean plate one the total …show more content…
in this experiment we want to see If using different beans for reproduction other then the mug bean, then they will produce less offspring. By using sertain method of division, replication, and messureing. Division alows us to seprate the different beans in to catagories, plates, and labeling for orginaztion. The method of messuring, after deviding the rest of beans in the plates, we measured the weight of each plate of the mug, black, and coffee beans. replicatin alow them to easly find there mate and replicate easier by using oppisite genders in each mug, black, and coffee beans plate. These methods help us ouline our experiment and futher get our
After a week, the beans were collected and the number of eggs on each bean was counted
Introduction The bean beetle also known as the Callosobruchus maculatus, is an agricultural pest insect from Africa and Asia. That can be found throughout the tropical and subtropical regions. The lifecycle of a bean beetles is quite short an adult been beetle lays their eggs on the external surface of a bean. The larva hatches from the egg burrows from the egg through the seed coat and into the bean endosperm without moving outside the protection of the egg.
The average growing period (days between each molt) will be calculated for each sample. This will be calculated by adding the amount of days a newly molted milkweed bug appeared in the specific stadium up until more than 50% of the milkweed bugs are at that stadium. The days will then be averaged to find the average amount of days it takes for the milkweed bugs to develop into that stadium. The final data that we will collect is survivorship rates. This will be calculated by the amount of insects that stay alive throughout the experiment.
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. Two chi-square tests were performed on the data to determine if the
The data observed and recorded in this lab shows that the concentration of miracle gro’ does affect the growth rate and germination speed of black eyed peas. The data is shown through two graphs and two data tables. The control group in this experiment is the seeds with a 0% concentration of miracle gro’, therefore the seeds with just water. The experimental groups are different concentrations of miracle gro’ including a 10%, 15%, 20%, 25%, and 30% concentration. The variable in this experiment is the amount/concentration of miracle gro’.
Some of these techniques include the use of
The beanium demonstrates this as there are more of one kind bean than there are of another kind. The results of this experiment could have been compromised by a number of things. The scales used seemed unreliable. When the beans were removed from the scales the numbers would count down from the weight they previously displayed. On multiple occasions they would stop at at negative number.
A Demonstration of Chemotaxis Between Flies and Various Substances (Sugar vs Bacteria) Abstract: The purpose of this lab based on the Drosophila melanogaster (the common fruit fly) reactions. Since the fly has been studied and observed for many years, and known for its unique chemotactic attractions to different stimuli, it was an ideal organism for the study being conducted. In the experiment the purpose was to be able to figure out whether the flies would be more attracted to sugar or bacteria.
Observation 6, explains that survival allows reproduction. The lab, Peppered Moth Activity, had two different types of moths; dark moths and light moths, and two different types of forests; light and dark. The dark forest is a great place for the darker moths to survive in because it helps them to camouflage and that gives them a great opportunity to reproduce their offsprings. While the lighter moths are being eaten,their population started disappearing. The dark moth parents are able genetically pass inheritable traits to their offspring, so they can also have an advantage to survive so they can also reproduce.
There are many different techniques
Additionally, it was difficult obtaining a piece of rhubarb that was thin and particularly red, therefore the effect could not be best observed in the cells. Part B: Design your own experiment Parts of this practical were taken and slightly altered from the following link http://www.markedbyteachers.com/gcse/science/investigate-the-effect-of-surface-area-on-osmosis-in-potato-tissue.html Aim: To observe the effect different surface area: volume ratios have on osmosis in potato tissue. Hypothesis: If the potato has a larger surface area: volume ratio, the quicker osmosis will take place and the larger the mass will be at the end of the experiment, therefore the difference in mass of the potatoes from the start of the experiment to the end of the experiment will be larger. Additionally, the potato pieces left in a saltwater solution will decrease in mass, whereas the pieces left in water will increase in mass.

It has to be stressed that the results do not differ much regardless of the choice of method
This model supports Darwin’s theory for many reasons. According to Darwin’s theory in this experiment, kidney beans were more likely to survive as it camouflaged with pinto beans. This was clearly seen as the levels of kidney beans at the end of generation 1 and till the start of generation 6 kept increasing, and the lima beans kept decreasing. Secondly, the kidney beans were red and camouflaged better with the pinto beans which were brown. The lima beans could not fit in because the skin color was white and could not camouflage with the pinto beans.
This experiment has to be carried out carefully
