recreate the Redi experiment that was preformed originally in 1668 by disproving the spontaneous generation of maggots on meat. In this experiment there were steps that first had to taken. Step1. Observation: Step2. Ask Questions: Step3. Develop a Hypothesis: Step4. Make a prediction: Step 5. Perform experiment: Step 6. Collect results: Step 7. Interpret results and make conclusions. This was done by placing meat inside two jars and observing What would happen over the course of 4 days to the meat

Compare the Social Brain Hypothesis and the Visual Specialisation Hypothesis The aim of this essay is to investigate the two major theories trying to explain why do primates have large brains. Even since the seminar study of Jerison in 1973 it has been acknowledged that primate brains are unusually large for their body size. There are three main groups of theories giving more or less persuasive explanations of the evolution of large brains and high cognitive skills in primates. The first group

suggest that long-lasting interrogations and techniques used by police that act to minimize the punishment of a crime’s punishment causes suspects to focus on short term consequences. In Experiment 2 the results further support the researchers’ hypothesis that the duration of an interrogation increased the likelihood of a participant to disregard future consequences when deciding whether or not to confess. In addition‚ participants who expected a long interview were more likely to give the alternative

The Stroop Effect: Automatic and controlled processes and the time taken to identify colours and words Abstract The aim of the experiment was test whether automatic processing could affect a colour related task. Previous research has found that the response time of reading the colour of the ink of colour associated words was greater than reading the colour of the ink of neutral words. The experiment retested the Stroop effect to measure the incursion of automatic processing. The results showed

Americans are facing skyrocketing health care costs today. I cannot help but think disease in some way relates to health. People have long established the link between good nutrition and healthy individuals. Examples of poor health and malnourishment continue to show up in poor countries. Although the United States maintains certain recommendations for basic nutrition‚ I think Americans still consume too much of the nutritionally empty foods and health care ends up dealing with the resulting

Which cereal stays crunchier for longer??? (No one likes soggy cereal) Aim: To observe which cereal absorbs the most milk Hypothesis: The Weetabix will absorb milk the quickest due to its large mass. Equipment: 4 bowls‚ sift‚ measuring cylinder‚ 4 different types of cereal Variables; Independent variable: Cereal Dependent Variable: amount of milk first placed in the bowl. (250mL) Risk assessment: A bowl might fall onto the ground and cut someone

Problem (2 Points) Sea turtle populations are falling due to human interference with nesting. Research (2 Points) Coastal development and human activity are disturbing turtle nesting cycles. Due to this‚ sea turtle populations are falling. Hypothesis (4 Points) If the drop in sea turtle population is caused by human interference‚ then areas with lower human interference will have more successful sea turtle nesting. Procedure (4 Points) 1. Choose a large area of coastline and ocean (25 mi

to pass through. I will keep the surface area the same by keeping the mass and length of the potato piece the same in each instance‚ by measuring and cutting it carefully. I am fairly sure that my results are reliable as they proved my hypothesis but I had two anomalous results. I think this is because as we did the experiment over 3 days‚ we did not have a chance to use the same potato as I had planned to do. All potatoes do not have the same tissue structure and also concentration

and semantic meaning. To do this we needed a camera to film the experiment‚ around 20 year 8 students and a classroom. In this investigation our independent variable was how 11-13 students would memorize different objects in different ways. Our hypothesis was that we think by looking at pictures students would memorize and study things better than just by looking at the word itself. To carry out the experiment we showed the students 21 pictures and then asked simple question about the picture e

There are 2 categories minus 1. The degrees of freedom is 1. 8. Find the probability (p) value for 1 degree of freedom in the 0.05 row. Compare this with the chi–square value you calculated in your Lab Notebook. What can you say about the null hypothesis? The probability value for 1 degree of freedom in the 0.05 row is 3.84 and the chi-squared value is 0.4848. There is little statistically significant difference between observed results of the experiment and the expected results.
