About This Chapter
Scientific Inquiry and Practices - Chapter Summary
Let us teach you about key concepts of scientific inquiry and practices through this online chapter. Our series of brief video lessons can teach you about basic science vocabulary and concepts, as well as the steps of the scientific method. You'll also learn to read and interpret scientific tables, graphs and charts and how to calculate mean, median, mode and range. Other topics covered in this chapter include the following:
- Experimental design methods
- Considering tools, materials, time and more in experimental design
- Standard deviation and shifts in the mean
- Probability of independent and dependent events
- Scientific knowledge and explanations through history
- Hypotheses, predictions, laws, theories and principles
- Chemistry lab equipment
Our team of experienced professional educators uses everyday language and examples in its video lessons on scientific inquiry and practices to help you remember key words and important concepts. Additionally, video tags allow you to jump to main points in the video, which can provide a quick way to review any related concepts where you're still a bit fuzzy.
Each video lesson is accompanied by a transcript, in case you learn better by reading than watching and listening. Also included with each video lesson is a self-assessment quiz, which can help you measure how well you've learned the material.
1. Science Vocabulary & Concepts: Study Skills & Word Parts
Learning science presents a unique set of challenges for students. In this lesson, learn the tricks of the trade as we discuss scientific vocabulary and other science study skills.
2. 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.
3. How to Read Scientific Graphs & Charts
How do scientists summarize their findings with visual aids? In this lesson, explore the different types of tables, charts and graphs that scientists use. Learn to read these effectively as a preview to your science studies.
4. 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.
5. Interpreting Tables of Scientific Data: Practice Problems
Complex table problems getting you down? Multi-question, situational problems don't have to be a drag on your testing performance. Learn how to apply three simple rules as we walk through two table problems together.
6. Interpreting Graphs and Charts of Scientific Data: Practice Problems
Do charts and graphs make problem-solving difficult? Complex problems with visual representations can drain your brain during a test. In this lesson, learn three simple rules for solving problems with charts and graphs. We'll try them out as we walk through two sample problems.
7. Design a Scientific Experiment: Example of Avery and Griffith's Experiment
What are the requirements of a scientific experiment? How do scientists design their investigations? In this lesson, we'll use the work of Avery and Griffith to explore the process of experimental design.
8. How to Calculate Mean, Median, Mode & Range
Measures of central tendency can provide valuable information about a set of data. In this lesson, explore how to calculate the mean, median, mode and range of any given data set.
9. Calculating the Standard Deviation
In this lesson, we will examine the meaning and process of calculating the standard deviation of a data set. Standard deviation can help to determine if the data set is a normal distribution.
10. Probability of Independent and Dependent Events
Sometimes probabilities need to be calculated when more than one event occurs. These types of compound events are called independent and dependent events. Through this lesson, we will look at some real-world examples of how to calculate these probabilities.
11. Chemistry Lab Equipment: Supplies, Glassware & More
When you bake a cake, you use different tools for each step in the process: a bowl for mixing, cups for measuring ingredients and an oven for baking. In this lesson, you will discover the name and purpose of many of the different tools that are used in the chemistry lab.
