Photo by Grace Nichols/U.S. Air Force. When you have a problem, how do you solve it? Do you consider what you already know about the problem, think of a possible answer and then see if your answer is right? If this is what you do, you are using the scientific method. The scientific method is a way to prove if our ideas about the world are right or wrong. Here's how it works. What Are The Steps In The Scientific Method? The scientific method has six steps, which will help you solve all kinds of problems. 1. State a problem or ask a question. 2. Gather background information. 3. Form a hypothesis. 4. Design and perform an experiment. This article is available at 5 reading levels at https://newsela.com. 5. Draw a conclusion. 6. Report the results. Step 1: State A Problem Or Ask A Question To begin using the scientific method, think about the world around you. You may see something that makes you curious, such as your sandwich drying out by lunchtime on some days. You might see a strange light in the sky. You might hear something that you are not sure is true. For example, a friend might tell you that wearing glasses makes your eyes weaker. Put your curiosity into the form of a problem or question, such as these: • Why does my sandwich dry out some days but not others? • What is that light in the sky? • Does wearing glasses make your eyes weaker? Step 2: Gather Background Information Read more about the problem or question and study it closely. Step 3: Form A Hypothesis Now use what you know about the situation to think of a possible answer to your question. This answer, or guess, is your hypothesis. A hypothesis is an idea in the form of a statement that can be tested by observations and/or experiment. Here are possible hypotheses to answer the questions above: • Plastic bags that seal keep bread from getting dry. They trap moisture better than plastic bags without seals. • That light in the sky is an airplane. • Wearing glasses does not make your eyes weaker. Step 4: Design And Perform An Experiment In this step, you find out if your hypothesis is right or wrong. You might be able to do this by doing research. For example, you could check the airport to see if an airplane flew over your house at a certain time last night. For the sandwich problem, the best approach is an experiment. An experiment is a controlled observation. The experimenter carefully changes one condition at a time and observes what happens. Conditions that change during an experiment are called variables. The variables in our sample experiment include the type of bread, how fresh it is and the type of sandwich wrapping. Only one variable at a time is changed during the experiment. The variable being changed is called the independent variable. In our experiment, this is the type of sandwich wrapping. This article is available at 5 reading levels at https://newsela.com. The condition that changes during an experiment is called the dependent variable. In our example, this is the amount of moisture in the bread. Results of experiments must be measurable, so we need a way to measure this moisture. We decide to weigh each slice of bread before and after the experiment. The difference in the weight is the amount of moisture that evaporated. Experiments must also be repeatable. We must write down our procedure and follow it carefully. That way someone else can carry out the same experiment and see if they get the same results. Step 5: Draw A Conclusion The next step in the scientific method is to graph or chart our results. Then we can study them and see if our hypothesis was correct. For our sample experiment, we compare the loss in weight of each bread slice after the wrapping is removed. What is our conclusion? Did our results support our hypothesis? Step 6: Report The Results Reporting our results allows other scientists to build on our work. It also allows them to repeat our experiment to see if they get the same results. This article is available at 5 reading levels at https://newsela.com.

  • Nuclear Capability, Bargaining Power, and Conflict by Thomas M. Lafleur
    Nuclear capability, bargaining power, and conflict by Thomas M. LaFleur B.A., University of Washington, 1992 M.A., University of Washington, 2003 M.M.A.S., United States Army Command and General Staff College, 2004 M.M.A.S., United States Army Command and General Staff College, 2005 AN ABSTRACT OF A DISSERTATION submitted in partial fulfillment of the requirements for the degree DOCTOR OF PHILOSOPHY Security Studies KANSAS STATE UNIVERSITY Manhattan, Kansas 2019 Abstract Traditionally, nuclear weapons status enjoyed by nuclear powers was assumed to provide a clear advantage during crisis. However, state-level nuclear capability has previously only included nuclear weapons, limiting this application to a handful of states. Current scholarship lacks a detailed examination of state-level nuclear capability to determine if greater nuclear capabilities lead to conflict success. Ignoring other nuclear capabilities that a state may possess, capabilities that could lead to nuclear weapons development, fails to account for the potential to develop nuclear weapons in the event of bargaining failure and war. In other words, I argue that nuclear capability is more than the possession of nuclear weapons, and that other nuclear technologies such as research and development and nuclear power production must be incorporated in empirical measures of state-level nuclear capabilities. I hypothesize that states with greater nuclear capability hold additional bargaining power in international crises and argue that empirical tests of the effectiveness of nuclear power on crisis bargaining must account for all state-level nuclear capabilities. This study introduces the Nuclear Capabilities Index (NCI), a six-component scale that denotes nuclear capability at the state level.

ABSTRACT The modern television viewer enjoys an unprecedented amount of choice and control -- a direct result of widespread availability of new technology and services. Cultivated in this new television landscape is the phenomenon of binge watching, a popular conversation piece in the current zeitgeist yet a greatly under- researched topic academically. This exploratory research study was able to make significant strides in understanding binge watching by examining its effect on the viewer - more specifically, how it affects their reception towards a television show. Utilizing a uses and gratifications perspective, this study conducted an experiment on 212 university students who were assigned to watch one of two drama series, and designated a viewing condition, binge watching or appointment viewing. Data gathered using preliminary and post questionnaires, as well as short episodic diary surveys, measured reception factors such as opinion, enjoyment and satisfaction. This study found that the effect of binge watching on viewer reception is contingent on the show.

Nucci Abstract In this paper, a generalized variable-coefficient Gardner equation arising in nonlinear lattice, plasma physics and ocean dynamics is investigated. With symbolic computation, the Lax pair and Bäcklund transformation are explicitly obtained when the coefficient functions obey the Painlevé-integrable condi- tions. Meanwhile, under the constraint conditions, two transformations from such an equation either to the constant-coefficient Gardner or modified Korteweg–de Vries (mKdV) equation are proposed. Via the two transformations, the investigations on the variable-coefficient Gardner equation can be based on the constant-coefficient ones. The N-soliton-like solution is presented and discussed through the figures for some sample solutions. It is shown in the discussions that the variable-coefficient Gardner equation pos- sesses the right- and left-travelling soliton-like waves, which involve abundant temporally-inhomogeneous features.

The primary objectives of the report are to raise awareness of these costs among the business community and to motivate all stakeholders to invest in the labor force of the future. The economic prosperity of the nation as a whole, employment rates, and the climbing dropout rate in Canada during the 1980s, when over one-third of Canada's youths were not graduating from secondary school, are considered in terms of education's importance. The myth of the over-educated Canadian is also discussed. The cost to Canadian society over the working lifetime of the nearly 137,000 secondary school dropouts who should have graduated in 1989 is $4 billion in present-value terms.

In Part I a technique based on extended Lax Pairs is first considered to derive variable-coefficient generalizations of various Lax-integrable NLPDE hi- erarchies recently introduced in the literature. It is demonstrated that the technique yields Lax- or S-integrable nonlinear partial differential equations (nlpdes) with both time- and space-dependent coefficients which are thus more general than almost all cases considered earlier via other methods such as the Painleve´ Test, Bell Polynomials, and various similarity methods.
