2 The ways in which investigation and mathematical skills in physics are expressed are set out in the following table of intended student learning. Key Ideas Students should know and understand the following: Intended Student Learning Students should provide evidence that they are able to do the following: Purposes of Investigations Investigations and experiments have a clearly defined purpose. State the purpose of the investigation or experiment. Investigations and experiments are based on existing information or issues. Before searching for information it is necessary to have a clear idea of the information required, the level of detail needed, and the appropriate facilities for extracting the information. For a given topic, state the key ideas or issues relevant to the information required, and identify the type of resource that might provide the information. Before undertaking an information search it is necessary to be familiar with search techniques, the way in which the information is structured, and the means of retrieving the information. Identify key search words and phrases for a given topic. Use an information source (e.g. library catalogue, CD-ROM, or the Internet) to obtain information about a topic. Questions and Hypotheses Investigable questions guide investigations based on issues in physics. Formulate a question for investigation based on an issue or phenomenon in physics. Investigations are often designed to explore questions and to develop possible solutions to those questions. Suggest possible investigations to test the question. Experiments may be used to test hypotheses. State a testable hypothesis, where appropriate. Designing Investigations and Experiments Design Scientific inquiry involves designing procedures, including practical investigations based on the scientific method or observations made in the field, to investigate questions. Designing an investigation involves identifying: what needs to be observed the measurements that need to be taken the techniques that need to be used the apparatus or measuring instruments needed. Design procedures to investigate posed questions or hypotheses. Design and carry out investigations to explore an issue or phenomenon in physics. Design and carry out experiments, using scientific procedures. Record and analyse observations. Every step in a practical or issues investigation serves a purpose. Describe the steps of an investigation. Draw or interpret diagrams of the apparatus used in an experiment.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
