Hypothesis: It’s crucial to predict the outcome of the experiment and provide a hypothesis. A hypothesis allows the researchers to think about their prediction in relation to the experiment’s outcome. In this case‚ I had a few hypothesis and predictions on this experiment. First off‚ refraction is the bending of light when it travels through different medium. Therefore‚ the light will bend and it will shift away from the original location. However‚ I don’t know where the shift will be‚ but according

dissolved oxygen. 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. If there’s more dissolved oxygen then there will be more fish. 3. What would your experimental approach be to test this hypothesis? I would go and check different ponds‚ lakes‚ rivers‚ and streams to track the amount of fish per dissolved oxygen levels. I would then compare the results to my hypothesis. 4. What are the independent

A hypothesis presents itself after a test is conducted‚ analyzed based on a set of observations‚ that provided knowledge or a educate guess for an answer (hypothesis). 4) The "Examples of Tasks" I selected for the Scientific Method Step: "Conduct an experiment" is accurate because: If a scientist is seeking answers from an experiment

Animal Behavior in Isopods based on Climate‚ Light‚ and Surface Abstract Pill bugs‚ (also named sow or potato bugs) are terrestrial crustaceans that consume decomposed leaves or other plants. In the lab performed on September 24‚ 2010‚ animal behavior of the isopods was recorded‚ specifically in the climate that they preferred. Various climates situations such as Light vs. Dark‚ Hot vs. Cold‚ and Wet vs. Dry were tested and observed. The results came back with the pill bugs favoring dark‚ wet

a body of water can effect fish populations. Answer = 3. Construct a hypothesis – Based on your observation in question 1 and your background research in question 2‚ develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water? Answer = 4. Test with an experiment – Describe an experiment that would allow you to test your hypothesis from question 3. This description must provide ample detail to show knowledge

Is psychology a true science? How do we define science? In Science the fundamentals are; testable ideas (hypothesis)‚ experimentation‚ objective data‚ conclusions based on balancing the evidence‚ and results that can be replicated. Testable Idea (hypothesis) Harry Harlow wanted to see if the behavior of baby monkeys that were separated from their mothers at birth. He wanted to see if the separation would affect their behavior later in life. Experimentation Harlow took 8 baby monkeys away from

example. Hypotheses are formed from questions or predictions roused by a certain theory. For example‚ in 1900 H. L. Bolley‚ using the theory of natural selection‚ formed the hypothesis that if he further bred the seeds of flax plants that did not die in the presence of a certain fungus‚ they would survive. Sure enough‚ his hypothesis was correct. 3. The theory of natural selection states that different members of a certain species are born with unique and distinct characteristics. These can either

decline as well. In this experiment‚ we will be testing whether or not the availability of oak trees in an environment will affect the distribution and abundance of robins. The hypothesis of the experiment would be as follows: The population size of robins is restricted by the availability oak trees present. This hypothesis would then lead you to predict that by removing oak trees from an environment‚ the population size of robins would then decline. In this experiment‚ both the control and the

Observing Osmosis in Potato Cells Planning Purpose: To observe the effect of osmosis on plant cells. Hypothesis: The higher the salt content of the water‚ the lower the mass of the potato. Variables: Independent: the salt percentage of the solution Dependent: the weight of the potato in grams Controlled: the amount of water the length of time between measurements the method of measuring the type of plant cells tested Equipment: (as seen on 2A Human Biology task sheet)

fellow classmates’ experiments would be recorded and added to our own results. The hypothesis was that more surface area exposed and smaller volume would result in a faster chemical reaction of the material. Since the Alka-Seltzer tablet would be less exposed and have a larger volume as a whole‚ the crushed tablet was thought to have a faster chemical reaction due to its small volume and larger exposure. The hypothesis was supported. The whole Alka-Seltzer tablet had an average of 7.80 seconds from
