conducted the experiment with termites in order to determine how they react to pheromones present in different colors of ballpoint pen ink. The experiment consisted of two parts: in first part we used a ballpoint pen with blue ink‚ in second – a ballpoint pen with red ink. The reaction of termites was measured by their performance in 1 minute. Every termite in experimental group went through 3 tries in each part of the experiment. The results were recorded and analyzed. The experiment showed that the

Motion of the system will be established by an initial disturbance. Furthermore‚ if there is no resistance or damping in the system‚ the oscillatory motion will continue forever with constant amplitude. Such a system is termed undamped. In this experiment the natural frequency for an undamped spring mass system is to be determine by using a mass-spring-damper. THEORY Newton’s 2nd law …………………….………. ( Equation 1 ) Hence‚ ………………….……...

conducting experiments or gathering data. The various processes that scientists go through to find evidence to support their theories (trial and error‚ systematic result collection‚ experimenting with a hypothesis etc.) all add a certain weight to their discoveries about a knowledge claim‚ often strengthening the argument for or against a certain aspect of the claim. One issue that arose while we were examining Human Sciences as areas of knowledge‚ on the other hand‚ was how experiments have a comparatively

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

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

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
