dominant thumb experiment is used to observe the correlation between handedness and thumb dominance and whether one inherited trait will always influences another correlated trait. Examples of this experiment of this can be traced back as far as 1908. In this experiment 50 people were asked to clasp their hands and the thumb dominance. Once the hands were clasped‚ one thumb would naturally overlap the other and the handedness of each subject was noted. The hypothesis of the experiment is that when

Discussion The results that were gained from this experiment refute the hypothesis. It refute the hypothesis as the most expensive detergent (morning fresh) did not have the largest zone of inhibition. Evaluate interesting aspects of

Blue Eyed Jane Elliot’s diversity training experiment is one of the most impressive educational research projects that I have ever seen so far in college. Her brave approach and the very professional behavior that she manages to maintain through the entire experiment allow the participants feel empathy and acceptance. Even though the entire movie was very interesting to watch and exposed very sad facts‚ there were some parts that stood out from the rest and deeply affected me. Towards the

at a 7. After two minutes elapsed‚ I again rubbed the sandpaper gently with my right index finger. My perception of the coarseness of the sandpaper did change during this experiment. On the second trial‚ the texture of the sandpaper felt smoother to the touch. I rated the coarseness at a 4 the second time. During this experiment‚ the sensory receptors located in the nerve endings on my fingertip responded to the presented stimulus‚ recognizing the pressure of touching the sandpaper. This information

Experiment 10 – Enzymes Enzymes are proteins that act as catalysts for biological reactions. Enzymes‚ like all catalysts‚ speed up reactions without being used up themselves. They do this by lowering the activation energy of a reaction. All biochemical reactions are catalyzed by enzymes. Since enzymes are proteins‚ they can be denatured in a variety of ways‚ so they are most active under mild conditions. Most enzymes have optimum activity at a neutral pH and at body temperature. Enzymes are

Materials and Methods In the experiment‚ a frog was obtained and dissected in a way to expose its heart and then tested using Lab Tutor software‚ a force transducer‚ and the PowerLab hardware (ADInstruments 2014). Frog dissection: Frogs that had been killed by being double-pithed were dissected as described in Lab Tutor. The frog was pinned down with the ventral side up. A longitudinal and a lateral incision were made along the frog’s abdomen. The skin was peeled back and the tissue and sternum

their behaviour did and it was nothing to do with individual personality. The experiment links into the Milgram experiment‚ in which ordinary people followed orders to give what they thought was electric shocks to people they could not see. Participants’ behaviour was slightly affected due to the fact that they were watched as opposed to a lurking variable (Hawthorne effect). This questions the reliability of the experiment and its findings to a certain extent‚ as we do not know how the participants

The Bouncy Egg Experiment! Mrs. Murosky December 19‚ 2013 Introduction: GOAL: The goal of this experiment is to get an egg to bounce. WHY IS THIS IMPORTANT? : The results of the egg experiment is important because it shows what the membrane of an egg looks like‚ but allows the experimenter to have fun in the process. LITERATURE: The acids in the vinegar make the shell deteriorate. Eggs contain "calcium carbonate"(this is what makes it hard)‚ and vinegar is an acid. When they both combine

Since there are many different definitions of handedness‚ the results of my experiment could be significantly affected by my choice. For the definition that I will use in this case‚ handedness is the hand that one prefers and performs better in use. Because the two most common definitions were the hand that one prefers‚ or the hand that one prefers to use‚ I made my own definition of combining together. In this experiment‚ handedness has to match both of the conditions of preference and performance

The experiment was divided into three days to test the detoxification activity of Beetles grown on Mung and Black-eyed peas. In day 1 of part I‚ four beetles per group were chosen from each food sources for both ANAE and BNAE activity. In part I‚ the crude extract was obtained by the experimental design outlined in the lab manual (Course Supplement for Bio 101‚ p.68). Each member of the group took care of one Bean beetle crude extract. First‚ the sex was identified by the following instructions of
