Why Do Dogs Play Introduction 200 Evidence of Play exists across the animal kingdom and indicates how old play is. Animal play has been described as a phenomenon, and research into play extends to all mammals and can provide a valuable insight into evolution in different species. Features of play are recognised across a wide variety of species in both wild and domesticated animals . Young animals often play, but dogs are unusual in that they carry on into adulthood. Research has not found play…

Title: 2-D Kinematics Purpose: The purpose of this experiment was to determine and relate the distance of a nerf-gun with a dart shooting out of it at an angle of 45 degrees. In addition, find the displacement and average acceleration of the dart as it shoot out of the nerf-gun. Hypothesis: If the dart is shooting out of the nerf-gun with choosing a small angle, then the distance will become larger, because if shooting at a right angle the dart is going to go straight up and then fall, but…

Animal testing is any kind of scientific test in which live animals of sorts are forced to undergo something that is likely to cause them pain, suffering, distress or lasting harm. This has been a very controversial thing that people everywhere are protesting about. There are two main uses of animal testing: medical and federal approval of products. Other uses include: advancing scientific study, models to study disease, develop and test different forms of treatment, and to protect the safety…

Horrors of Animal Testing 100 million animals are killed each year for medical training, biology lessons, experiments and commercial testing. They are usually are mice, rats, frogs, dogs, cats, rabbits, hamsters, guinea pigs, monkeys, fish and birds. But when companies and scientists experiment on them, the tests are sometimes really brutal and inhumane. Animal testing and experimentation has to end. Animal testing is a big problem, because the animals are sometimes…

The marshmallow study was a tossup regarding the outcome of the children. What real evidence was produced to make this a true experiment to believe? To state that the children who ate the marshmallow were destined to be unsuccessful I think is a bit far stretched. If anything, the children that decided not to eat the marshmallow practiced self-control and that was to earn the extra marshmallow. Self-control is something the other children lacked, but just like anything it can be strengthened and…

It is estimated that more than 100 million animals worldwide are used in experiments each year. Animal testing is a big problem in today’s world because there are so many animals are being abused in labs and hurt for even killed every year. If you get caught once it’s a warning, if you get caught twice it’s a fine, and if you get caught three times it’s jail time. If animal testing isn’t banned, animals will start to die off from cruelty or diseases. Animal testing must be stopped or decreased…

smoke on the larval development of Vanessa cardui, commonly known as the Painted Lady. The hypothesis for this experiment was, “if tobacco smoke has a negative effect on the development of Vanessa cardui larvae, then, larvae exposed to tobacco smoke for 15,10, or 5 minutes will display reduced length (cm) compared to control larvae receiving 0 minutes exposure”. To start the experiment, the condiment cups for each experimental trial were placed around each of the three candle holders. Then the 5…

unknown and that you are making an assumption about what it is. A good observation should include your 5 senses; touch, smell, taste, hear and sight. Using all five of your senses will allow you to gain more information on what happened during the experiment. However, you must be careful when you’re using the senses smell and sight. Working with chemicals, liquids and objects can remind you of other things you may have encountered in the past. Don’t mix this up with what you are currently…

During the laboratory section two devices were used; these were the DE2-115 board and a computer, containing the software system Quartus II. Each of these devices were very significant for gathering information during the duration of the lab and shall be explained further. The DE2-115 board was the device provided in the lab that displayed the output for viewing by the student. The portions of the DE2-115 board that were used during the duration of the lab were the switches, the LEDs, and the…

Being a hands-on learner, I excelled the most in lab. I was always delighted to go in and learn how to do all the different procedures and acquire new skills that we would perform in the clinical setting. I enjoyed learning new techniques and figuring out the rationale as to why one may be better than the other. I also took pleasure in teaching and helping fellow students who were practicing their skills in the lab. Throughout my clinical experiences I was outgoing, friendly, curious, and…
