example‚ I am now studying science so I need to do many experiments. An experiment contains many complicated steps. Only a minor mistake will result in the failure of whole experiment. Therefore‚ I communicate with my group-mates and divide the experiments into different parts. Each group-mate is responsible for a part of it. We help each other during experiments. Because of the cooperation and communication of group-mates‚ the experiments can be completely successful. Moreover‚ I am a trumpeter

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

CHE 101 Experiment 1 Lab Techniques and Measurements Purpose: The purpose of this lab experiment is to review and learn the proper techniques for the measurement of length‚ mass and temperature. After this experiment I expect to have a better knowledge on how to correctly and efficiently measure for future lab experiments.

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
