put 10 Pill Bugs in the opening between the two circles‚ and timed them for one minute. This gave them time to choose dish 1 or dish 2. We then counted the number of Pill Bugs in each circle. We did this 3 times. This was the control group in the experiment. Then we changed the independent variable: the environment in each of the dishes. In dish 1‚ we took strips of paper and

The next part is experimental setup and procedures which describes the setup of the experiment (fig 1) and furthermore information‚ like which microscope they used (Levenhuk BioView 630 or Olympus BX-51) so the reader could replicate this experiment. After the setup there is an experimental results and discussion section which provides information about the nanogratings and nanostructures (fig 2 and 3) and also an

Extracting DNA from Human Cheek Cells: Conclusion The hypothesis of my experiment‚ if the strawberry DNA product was strandlike yet clumply then human epithelial cell DNA will be strandlike and clumpy too‚ was supported. This is because through the observations noted when the lab was being conducted‚ it can be seen that the human epithelical cell DNA was small‚ stringy‚ clumpy and squishy‚ just like the strawberry DNA product. Other observations of the human epithelial cell DNA was it was not only

The alternative hypothesis by using the McCrink and Wynn’s theory is the five month olds have some numerical knowledge that can solve simple math problems.4b. A possible outcome of the current experiment is there no difference in five month olds in the experimental group and control group. A possible outcome that would support the alternative hypothesis is five month olds use dishabituation in the experimental group compared to the control group

to the independent variable in a predicted way‚ than the researcher can conclude that the independent variable is the cause of the change of the dependant variable. This is the process of a cause and effect experimental research test. In a field experiment‚ subjects are observed in their natural outdoor environment so that researchers can study their behavior. Most of the time‚ the subjects are not aware of the researchers and so usually the conclusions are mostly accurate. For example‚ researchers

Animal experimentation‚ also known as animal testing‚ is the use of human substitutes animals for experiments. Experiments on animals began with Greek anatomists. Who are physicians‚ and writers who formed theories on European medicine . During that time doctors had no understanding of the anatomy of humans or any other species. These physicians would perform surgery live on animals to grasp the parts of an animal’s anatomy and their functions. Through the knowledge of dissecting animals many doctors

what many people tend to forget are the millions of animals that are tortured or killed during the process of these painful‚ deadly experiments. Many people seem to misunderstand animal nature and the laboratory procedures and techniques that are executed on the animals. The procedures are cruel‚ unreliable‚ and harmful. I think that the use of animals during experiments should be restricted for‚ many animals are killed or tortured while being tested‚ there are other possible materials that could be

For each variable identified‚ give a specific suggestion for how it can be controlled during the experiment. The independent variable in this experiment will be the time of day that the plant is being watered. The dependent variable will be the plant growth rate. Five variables that should be controlled during the experiment: 1. How much sunlight the
