Background Paragraph:

The background paragraph is used to introduce your reader to your subject matter. Our subject matter for this class is magma. We know that magma comes in different forms such as basaltic, andesitic, and rhyolitic. We also know that several factors influence how magma behaves. I am going to give you a data table with roughly twelve volcanoes with a set of variables. From this data table you are going to identify the type of magma and make a prediction as to the shape of volcano and danger this magma will have on people living near the volcano.

So your background paragraph will explain what factors influence the formation of a volcano and will include a short paragraph with your testable question.
