About This Chapter
Earth Science Investigation & Experimentation - Chapter Summary and Learning Objectives
The short, entertaining video lessons included in this chapter can teach you how to dig into Earth science research, in particular, and scientific experimentation, in general. Instructors also show you how to use research tools in the field or lab and present your own findings. You can even learn what it takes to assess the validity of scientific evidence. This chapter can help you learn how to:
- Identify tools and techniques for conducting an experiment
- Read and interpret a variety of charts, graphs, tables and maps
- Report experiment outcomes in oral and written presentations
- Identify and interpret changes to natural phenomena

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. 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. 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.
4. How to Construct Graphs from Data
This video describes how to create a line graph and explains the four main parts that graphs need to contain: 1. previously collected data, 2. picture representations, 3. use of the correct graph type, and 4. labels. This lesson also covers dependent and independent variables.
5. Graph Terminology Axis, Range & Scale
This lesson will focus on what the X- and Y-axes are and what the terms range and scale are as they pertain to graphing. Later in the lesson, the idea of scale breaks will be discussed.
6. 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.
7. How to Write a Written Report of a Scientific Investigation
Many times, writing a good written report of a scientific investigation is just as important as the experiment itself. In this lesson, we'll learn why the hypothesis, procedure, and results are so important.
8. How to Give an Oral Presentation on a Scientific Investigation
After watching this video lesson, you will know how to give an oral presentation that delivers the important parts of your scientific investigation in a way that your audience will like and understand.
9. How to Interpret Scientific Evidence
Watch this video lesson to learn how you can tell whether or not your scientific data answers your question by determining what your data is telling you. Then test your new knowledge with a quiz!
10. How to Read Topographic and Geologic Maps
This lesson explains the main features of topographic maps, including contour lines, index contours and contour intervals. It will also cover two rules that all contours follow and discuss geologic maps and the information they contain.
11. How to Construct and Interpret a Scale Map
This lesson will explain what a scale map is and how it represents two different things on the map expressed as a ratio. This lesson will also demonstrate the steps needed to create a scale map from any ordinary map.
12. How to Interpret Events from Natural Phenomena
This lesson will explain what scientists can determine from looking at Earth's rock layers. It will cover terms used to describe parts within the layers of rock and how layers can change over time. Relative dating will also be discussed.
13. How to Identify Changes in Natural Phenomena Over Time
Have you ever seen a volcano erupt? Have you seen the Northern Lights? If not, don't worry. You've probably seen or heard other natural phenomena. Let's find out together how we can detect changes to phenomena over time.
