About This Chapter
MTTC Physical Science: Conducting Research - Chapter Summary
When teaching students about science, you have to give them a strong foundation, and that includes instructing them about the steps for conducting proper scientific research. Get reacquainted with those steps in our chapter as you prepare for taking the MTTC Physical Science exam. After reading through the transcripts and watching the lessons, you should know the key facts about the following:
- Scientific observation, questioning, and investigation
- The steps of the scientific method
- Regulations, risk assessment, and safety issues
- Appropriate tools, data collection methods, and sampling techniques
- The uses of different variables and the methods for interpreting them
- Strategies for designing experiments
All of our lessons address the subject matter using a friendly and exciting approach. After all, this is a subject that you are passionate about, and we want to respect that passion by giving you an informative and lively study guide. Follow along with the instructors in the videos. Watch the lessons repeatedly if you need, and let our transcripts help you commit those key terms to memory. As a fun way to measure your progress, answer quiz questions after each lesson. Your results to our chapter exam may give you a hint as to whether you are ready to take the MTTC Physical Science exam.
MTTC Physical Science: Conducting Research - Chapter Objectives
There are several certification requirements for teachers in Michigan who wish to specialize in secondary science coursework, and one of those includes passing the MTTC Physical Science exam. This exam is used as an appraisal of each applicant's skill, familiarity, and knowledge concerning the physical sciences. There are three key sections on the exam: physics, chemistry, and scientific inquiry. Of the 100 questions in total, all of which being multiple-choice, 20 questions will address topics about scientific inquiry, including techniques for conducting research.
1. How Scientific Observations Lead to Scientific Questioning
Scientific observations are a major component of the scientific process because they lead scientists to ask questions about the world around them. These questions may then be refined with continued observation, or they may be tested through experimentation.
2. The Scientific Method: Steps, Terms & Examples
The scientific method is more than just hypotheses and experiments. In this lesson, we'll explore the themes and variations that make up the world of science.
3. What is Scientific Investigation? - Definition, Steps & Examples
Scientific investigation is the way in which scientists and researchers use a systematic approach to answer questions about the world around us. Read on to find out more. A quiz is provided to test your understanding.
4. Scientific Investigations: Data, Evidence & Reasoning
What is a scientific investigation? And how are data, evidence, and reasoning central to the scientific process? Learn about the difference between data and evidence and why logical reasoning is just as necessary as data itself.
5. Conducting Scientific Research: Safety Concerns & Regulations
When scientists conduct research, safety is a top concern. Learn about the kinds of hazards a scientist faces depending on the kind of work that they do, as well as some risks with scientific research. Plus, see how safety regulations protect all of us.
6. Experimental Design in Science: Definition & Method
What are the requirements of a scientific experiment? How do scientists turn hypotheses into theories and laws? Learn the answers to these questions and more in this lesson on the design of scientific experiments.
7. Understanding Risks & Taking Safety Precautions in Science Experiments
An important step in designing your experiment involves identifying and evaluating any potential safety risks. Knowing what these risks are ahead of time can help you avoid accidents and dangerous situations, which helps keep the experiment safe and fun for all.
8. Sampling Techniques In Scientific Investigations
We can learn a lot by gathering information from a small subset of a larger group. By sampling this smaller group, scientists can save time and money while still gaining a good understanding of the population as a whole.
9. Using Appropriate Tools for Scientific Tests & Data Collection
A properly run experiment depends on using the right tools, both for data collection and analysis. In the end, it will save you time, money and frustration to spend some time planning out which tools are most appropriate for your work.
10. Variables & Controls in a Science Experiment
After watching this video, you will be able to explain how science experiments are conducted; what variables, controlled variables, and controls are: and why these things are important. A short quiz will follow.
11. Researcher Variables that Affect Internal Validity
Scientists want only the independent variable to affect the outcome of their studies, but sometimes it is the things they do themselves that change the outcome. We'll look at three common researcher-related variables: researcher bias, selection bias, and researcher personality in this lesson.
12. Identifying & Interpreting Independent & Dependent Variables
Scientists answer questions by performing experiments that have an independent variable, a dependent variable and at least one control variable. By controlling, adjusting and measuring these variables, scientists find answers to their questions.
