Introduction to Water Pollution
Book Chapter |
This lesson assesses students’ prior knowledge about groundwater pollution and has students investigate types and sources of water pollution. Note that this introductory activity sets the stage for subsequent learning…
-
Book Chapter |
Nanoscale science and technology play central roles in our understanding of how Earth works and in the environmental science field of study. As a freshwater source, groundwater is second in abundance only to water found…

Introduction to Nanotechnology
Book Chapter |
Imagining differences in scale can be very easy (a softball is bigger than a baseball) or very difficult (how can we imagine the size of a galaxy?). It is perhaps most challenging to build conceptual frameworks for…

Documentation and Research Paper Setup
Book Chapter |
After organizing the raw data from your experiment and performing statistical analysis, you are ready to move to the next part of your research project—sharing the results of your experiment. You do this by writing a…

Presenting the STEM Research Project
Book Chapter |
An important part of conducting research for all STEM professionals is to communicate their study results. This is generally accomplished in two different ways. The first is to write a scientific paper, in order to have…
-
Book Chapter |
In this chapter, you will learn how experiments are structured. This structure or experimental setup is called the research design. The research design of an experiment determines both whether the experiment is likely…
-
Book Chapter |
After you have begun background research on your topic and have a preliminary hypothesis, you will write your proposal. A proposal is a document that describes the proposed experimental design of your research project.…

Book Chapter |
Once you have collected data from your experiment, you will need to calculate various descriptive statistics explained in this chapter. This chapter contains guidelines on how to graphically represent data and provide…
-
Book Chapter |
Graphical representations are visual ways to represent raw data, descriptive statistics, or inferential statistics in order to highlight important findings from a research study. You can use the graphical…

Inferential Statistics and Data Interpretation
Book Chapter |
This chapter is organized into two parts. In the first part, the author briefly introduces inferential statistical tests that are commonly used in STEM research. The description of these tests is meant only to provide…
