About This Chapter
Scientific Investigations Overview - Chapter Summary
Scientific investigations are the focus of this chapter, in particular, the variables and technology used. In these lessons, you learn about the vital relationship between a well-written hypothesis and an experiment, as well as the process involved to create one. Topics of study also include the importance of safety in your investigations and how to minimize safety risks when performing experiments and investigations. This chapter will enable you to:
- Understand the systematic approach researchers use in investigation
- Identify the specific variables used in an experiment
- Use data to revise your hypothesis and refine your experiment
If you're looking for test prep material you can use to help you get ready to take an exam, our lessons and chapters provide all the information you'll need. Self-assessment quizzes and chapter tests gauge your understanding either before or after you've reviewed the lessons. Printable lesson transcripts work well as hard-copy study guides if you like using an offline format better.
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. What are Variables in Science? - Definition, Types & Examples
In this lesson, you will learn the definition of variables in science. In addition, you will be able to define the specific types of variables in an experiment.
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. Modifying Scientific Investigations Based on Evidence
In this lesson, we'll learn about how the evidence from your scientific investigation supports or refutes your hypothesis. We'll also go into how to use your data to revise your hypothesis and refine your experiment.
5. 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.
