Research Methods In today?s world there are a vast number of ways to do research. Some are good and some are bad. The research method you use also depends on what kind of outcome you?re looking for. The two main concepts I believe that I found most useful was the Foundations section under Knowledge Base and the Computer Simulations section.

Chapter Two What is science? Science: ? is a methodical, logical process for producing knowledge about natural phenomena ? a cumulative body of knowledge ----- Table 2.1 : Basic Principles of Science (7) Science depends on skepticism and accuracy ? Ideally scientists are skeptical and un biased. ? Scientist strive for ? Accuracy- correctness of measurement ? Reproducibility- Repeatability of result : Repeating studies or tests is called replication Deductive and inductive reasoning ? Deductive reasoning- logical reasoning from general to specific ? Inductive reasoning- reasoning from many observations to produce a general rule ? It is also important to recognize the role of insight, creativity, aesthetics, and luck in research

Pre-AP Chemistry Modern Chemistry (2006) Chapter 2 Notes-Measurements and Calculations 2.1 The Scientific Method The process that researchers use to carry out their investigations is often called the scientific method. The scientific method is a logical approach to solving problems by observing and collecting data, formulating hypotheses, testing hypotheses, and formulating theories that are supported by data. 2.2 Units of Measurement Units of Measurement Measurements are quantitative information. They represent quantities. A quantity is something that has magnitude, size, or amount. A quantity is not the same as a measurement. For example, the quantity represented by a teaspoon is volume. The teaspoon is a unit of measurement, while the volume is a quantity.

Psychology Textbook Notes- Ch. 1 The Need for Psychological Science: The Limits of Intuition and Common Sense Hindsight Bias-THE TENDENCY TO BELIEVE AFTER LEARNING A N OUTCOME that foreseen ?I knew it all along phenomenon). Unanticipated scientific results indeed ?seem? like obvious common sense or justify it to that! Common sense describes what has happened more easily than it predicts what will happen. Intuition can be wrong & common sense! Overconfidence: Thinking limited by ?after-the-fact? common sense hindsight bias. We could of done that DUH attitude example anagram scrambling after seeing the solution. 98% college students confident they won?t drop out ? yet half do OVERCONFIDENT! More confident than correct!

What Makes a Worm?s Heart Race? Part 1 - Learning Name: Hour: Date: Purpose: To explore the impact of treatments on the pulse rate of the worm Lumbriculus variegatus while refreshing and refining your understanding of experimental design with a focus on recognizing and minimizing experimental bias. Objectives: Upon completion of this activity, you should be able to: Count pulse rate in blackworms (Lumbriculus variegatus). Demonstrate the ability to design and perform an experiment using the strong inference model and multiple hypotheses with attention to the minimization of experimental bias. Demonstrate an understanding of graphing and the use of simple statistical data analysis to evaluate the impact of an experimental treatment.

www.asbiology101.wordpress.com MAGNIFICATION AND RESOLUTION Because cells are too small to be seen with the naked eye, the light microscope was developed to produce enlarged and more detailed images of cells. The magnification of an image is how much bigger it appears under the microscope than it is in real life, and is worked out using the following formula: magnification = image size ? actual size However, magnification on its own does not increase the level of detail seen, it just increases the size. The term resolution refers to the ability to see two distinct points separately. For example, if the resolution of a light microscope is 200nm (0.2?m), this means
