Knowledge gap hypothesis

normal term theory, a scientific theory must be backed by evidence. In general, the term theory suggests an idea with evidence or proof to back it up. A hypothesis is an idea that hasn’t been proven yet and, according to the Merriam-Webster Dictionary, every scientific theory begins as a hypothesis. If evidence is then accumulated to support the hypothesis, then is begins a theory as it has evidence to support the belief. Evidence linked to theory can involve observations, experiments and…

table. 5)Measure 400mL of water with a graduated cylinder. 6)Add it to your cup. 7)Carefully place your egg in the cup and allow it to sit for 24 hours. 7)Hypothesize what you think will happen to the size of the egg and record in a data table. Hypothesis Vinegar- If an egg is placed in vinegar, then the mass of the egg will increase because the shell will soften. Syrup- If the egg is placed in syrup, then the mass will restore to normal because the syrup is thick and it will push the…

Discussion: My first hypothesis that the sepia eye and ebony body experimental cross would result in a 9:3:3:1 ratio, and that the traits would be autosomal, unlinked recessive, was found to be false. I chose to reject my hypothesis because my calculated test statistic, 587.5, was larger than the critical value, 7.815. The traits, ebony and sepia, are linked, seeing that they fit in 2:1:1 linkage ratio and that the recombinant number is smaller (Table 1.1). They are autosomal; the amount of…

Hypothesis: Individuals who prefer high fat and sugar foods will priorities attention to images of these foods and therefore have a significant increase in their response time, compared to those who do. Those whom received a high preference of high fat foods in the pre-test will score significantly higher in the questionnaire in the post-test, with a longer reaction time in the odd one out task, indicating that after exposure to food stimuli these individuals attention was impaired. Method…

In our study, we had two controls that we placed the Lumbriculus variegatus into. First, we used spring water to get the normal heart rate of the worms. The other control was a caffeine solution that served as our positive control. Our other solutions that we exposed the worms to consisted of increasing concentrations of two different NSAIDs (ibuprofen and aspirin). For each NSAID, we had a solution equivalent to the recommended dosage for a person based on body weight (the proportional dosage…

to have adequate research, one needs to provide a hypothesis to have validity. He argued that if you don’t come up with a hypothesis before you examine the phenomena, you would not be able to test the evidence fully. He states that if you create your theory after finding evidence, there is no way to test the validity of the theory using that evidence. According to Keynes, he stated that those who provide evidence after coming up with a hypothesis essentially will have more weight placed on it as…

This experiment is the study on the effects of household drugs on the circulatory functions of the blackworm, Lumbriculus variegatus. Household drugs, such as tea, coffee, tobacco, and cigarettes, are easily accessible and may be used every day by a typical human being. These household drugs contain caffeine and nicotine at different concentrations. In addition, caffeine (found in tea and coffee) and nicotine (found in tobacco and cigarettes) can influence the behavior of physiological processes…

The Effect of Caffeine on the Metabolic Rate of Goldfish Intro/Materials and Methods For this experiment, the hypothesis is that there is a difference in the metabolic rate of goldfish, measured in oxygen consumption, when the fish are in pure water versus when the fish are in water with 25 mg of caffeine. The null hypothesis is that there is no difference between in the metabolic rate of goldfish when the fish are in pure water versus when they are in water with 25 mg of caffeine. Results…

Experiment 1: Changing the degree to which the catapult is released from. Abstract: For a long time, catapults have been used in many different ways and come in many different sizes. In physics, they can be tested and used in many different ways also. The first investigation conducted was to see how the degree at which you release the catapult from affects the range of the projectile. Five different angles were tested and graphed. The relationship between the range and degree of release were…

*** The methods based off the procedures section of the Lab Handout *** (Blanar, 2017) In this experiment, the first step performed was that a compound light microscope was obtained. A Daphnia magna specimen was then pipetted into the well of a concave slide, but not too much water was added to prevent the specimen from swimming away from focus on the slide. If too much water is present a tissue can be used to wipe off the excess. The specimen was put under the microscope at the lowest…
