About This Chapter
Scientific Inquiry & Experiments - Chapter Summary
By working through these lessons, you can deepen your knowledge of scientific inquiry and experiments. For example, you can take a look at the appropriate tools to use for scientific tests and data collection. This interactive chapter can also assist you with understanding how to make a clear statement that can be tested and measured. After reviewing the lessons, you should be ready to:
- Explain what scientific investigation is
- Describe how to create a hypothesis
- Design an experiment based on a hypothesis
- Discuss how to properly run an experiment
- Perform calculations with measurements to limit uncertainty
- Define accuracy and reproducibility in relation to science experiments
- Recount methods used to organize and report experimental results
These lessons can assist you with better understanding scientific inquiry and experiments. Vocabulary words are highlighted in bold for quick reference, and a brief quiz is available for each lesson to test your knowledge. Also, each video lesson includes a full written transcript that you can print and use as a study guide.
1. 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.
2. Developing a Scientific Hypothesis
This video describes how to create a hypothesis and includes the three main things needed to create a strong hypothesis. You'll learn how to make a clear statement that can be both tested and measured.
3. Designing an Experiment to Test a Given Hypothesis
A well-written hypothesis is the key to any well-designed experiment. In this lesson, we'll work through the process of designing an experiment based on the hypothesis it's meant to test and see how the two work to complement each other.
4. 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.
5. Measurements & Uncertainty in Science
In this lesson, you will discover the importance of precision and accuracy in science while learning to make measurements. Also, you will understand how to perform calculations with measurements that conserve precision and limit uncertainty.
6. Evaluating Data from Scientific Investigation
After watching this video, you will be able to explain the meaning of the terms 'accuracy' and 'reproducibility,' or precision, as they relate to science experiments. A short quiz will follow.
7. Organizing & Reporting Experimental Results
This lesson discusses how to present experimental results in a scientific paper, and includes writing style, why it is important to be selective in reporting data, and when to use text, tables, and figures.
