956 Crickets

The purpose of this experiment was to determine if cats have a color preference. I wanted to do this experiment because I took an interest in my cat’s vision. My hypothesis was that my cat would prefer the color blue. I used 5 different colored balls of yarn. They were placed in the same spots and sequence each time. I conducted this experiment for a total of four-weeks. I set my cat up behind a line of painter’s tape and let her approach a yarn ball and play with it. I recorded how many times she approached each color. At the end of the experiment I discovered that my hypothesis was not supported. My cat chose to play with the yarn colored black rather than

My predictions for the acceptance of the null hypothesis were very similar to the actual results with a few variations. My prediction of total arousal times for the first interval were the same however, on the second interval I had 60 total arousal times for the bats injected with the European P. destructans strand and the actual results had a total arousal of 80 bats injected with the European strand at interval

Each of these inputs is exactly the same except for the one physical characteristic of the finch: the beak. Each scenario will be run at the same time and show comparisons as to population growth and changes. The first run will be set at 100 years to revisit the information which is selected in the main menu prior to running the experiment. Not only is the information regarding each population’s beak size over time important but the population growth is what is needed for the hypothesis. After the first run is completed the inputs will be changed to reflect a 200 year period where population B1 with the

A Chi-square test was used for hypothesis testing. This is used to determine that the observed number of wins of the resident from the trials is different from what would be observed by chance. The null hypothesis was observed wins will be equal to that expected by chance. On the other hand, the alternative hypothesis was observed wins will not be equal to that expected by chance. The class’ hypothesis was proven correct that resident male crickets have a greater motivation to defend

According to many studies on baseball bats scientist believe that metal bats outperform wood bats. One study called “Journal of Applied Biomechanics” used one wooden bat and five contrast metal bats. They chose six different players to perform the study. They found that while the players were in the batting cage that the exit velocity of players using metal bats was much faster than players using wood bats.

When we finished collect the data we make a graph. We start with white color light first trial. We saw 4-5 of Daphnia come stayed few second and two of them left. We get same result on second trial. When the third observation was different because only one Daphnia was left all of them went to dark place. While we are observing the Daphnia with red color light they are not attractive. Two of Daphnia came and stay about five second and one left only 1 was stayed stayed stayed We use the same light second time same result we got only 1 stayed. We use the same color light for third trial we saw some difference. They are was no Daphnia at all . None of Daphnia accept the red color. Finally we use green color. First trail was strange none of Daphnia came to near the light also same result in second trial. The third trial one Daphnia came on nearby the green color. Our group find out that white color light was most attractive for Daphnia. My dependent group is number of Daphnia attracted with light. My independent group is diffrent color of light. My control group is white light and my experimental group is green light and red light.

With a P-value of 0.00, we have a strong level of significance. No additional information is needed to ensure that the data given is accurate.

Introduction Animals usually compete for resources, mostly food, and the motivation to fight is directly related to how much of a resource exists in that environment according to Nosil (2002). The residency effects of House Crickets most likely follows the trend of other species; animals tend to be territorial and the space that they reside in is their space. They will defend it if another animal invades and poses a threat. This was already assumed prior to the House Cricket experiment.

In the article titled “Princess Alice is watching you: Children belief in an invisible person inhibits cheating by Jared Piazza, Jesse Bering, and Gordon Ingram the experimenters describe an experiment to test the prediction that children would be less likely to cheat if there is an invisible person watching them. Within this experiment there were 2 children groups, one group was of 39 children between the ages of five and six. While the other group consisted of 29 children with the age of eight or nine. One of the six year olds was omitted from the study due to the fact he could not comprehend the task at hand. Within this experiment the children were asked to complete a task and were told either a) they were in the presence of a watchful invisible person, b) they were being observed by a real adult or c) they were unsupervised. This was a three x two factorial, with the three meaning condition while the two meaning age group. The experimenters introduced both Princess Alice (invisible person) and the real observer as friendly. The game consisted of children having to throw a Velcro ball at a target and get it to stick and if they completed a take they received a prize. But the task was nearly impossible due to three rules the children had to follow. These rules were placed to cause the children to cheat. The procedure they followed for the children was: First the children arrived with their parents and played the game with the

The tests that the ravens had to perform both showed that ravens are more intelligent than we think. The ravens used tools such as the rocks to trade for treats and for the blue bottle cap experiment, they either chose to wait to get a better treat or get a inferior treat immediently. On both experiments the ravens showed excellent answers and proved that they are smarter than we know. The blue bottle cap test was the better choice to show the ravens intelligence because it showed that they can plan ahead and chose themselves whether they want a better treat later or a simple treat now. In conclusion, the blue bottle cap experiment was the more important test to see how intelligent ravens can actually be.

Many more such tests of prey model have been conducted with species ranging from insects to mammals with similar results.

There are 900 species of crickets; one of the most common species, used a lot of times for bait, is the house cricket or Acheta Domesticus. Most species of crickets are nocturnal meaning they are more active at night. House crickets tend to be found in the Eastern part of the United States. House Crickets have shorter lifespans than most other species of crickets living only about three months while other cricket species such as the mole cricket can live for about a year.

In the experiment, it tests how different movie genres have different effects on people’s heart rate. The hypothesis for this experiment is if the aspects of horror in a movie increase, then the heart rate will increase, when heart rate is a function of the amount of horror. To test this experiment, first gather a group of people to test their heart rate before and after watching movies of different genres. Next, take everyone’s heart rate before watching a movie. Then, everyone will watch 30 minutes of a movie and record their heart rate after watching it. With at least two more movies of different genres, continue taking the heart rate before and after watching. After recording all the heart rates, observe and compare the different

In this case, level of significance, α was not provided. Therefore, the analysis will be evaluated based on two α values which are:

The instrument used is questionnaire and chi-square is used to test the relationship between the variables, which has proven that there is a
