What's Out There: Exploring a Science Text in A Black Hole Is NOT a Hole
Read the introduction from a geology book. Metamorphic rocks are rocks which have changed from one type to another. For example, slate is a metamorphic rock made by clay. Scientists believe that heat and pressure are two important elements in changing rocks. The following experiment with aluminum foil will help prove this theory. Which is the hypothesis found in this introduction?
Heat and pressure change rocks from one type to another.
Read the introduction from a science website. Electromagnetic force sounds very complicated, but I wanted to understand how it works. My experiment allowed me to create my own electrical field using a nine-volt battery, an iron nail, and some paperclips. This experience helped me understand electromagnetism and the way it works. Which focus question is the author trying to answer?
How does electromagnetic force work?
Which biographical fact about the author of A Black Hole is NOT a Hole makes her a credible source?
She works with NASA on science programs.
Read the excerpt from A Black Hole is NOT a Hole. I found lots of great information in science magazines, such as Scientific American, Astronomy, and Sky and Telescope. These led me to other useful resources. When it was time to get to the details, I looked at scientists' reports, along with summaries of the reports, in scientific journals. How can these scientific magazines be evaluated as credible sources?
The reader must look for current copyright dates.

Read the excerpt from a science text. In our experiment, we filled two identical glasses with water. To one glass, we added two tablespoons of salt and stirred. To the other glass, we added four drops of food coloring and stirred. This excerpt is most likely to be found in which part of the scientific text?
methods
Read the introduction from a biology book. Think about the way your body feels after a swim in a cold pool. Think about the way your body feels after a hot bath. Temperature affects human beings in many ways. How does temperature affect plants? Do they photosynthesize faster in cold weather or hot? Students can measure the way sugar is transported within a plant at different temperatures to find these answers. According to the introduction, why are plants being studied?
to see how temperature affects plants
Read the introduction from a children's science magazine. Have you ever looked at a spray of water and seen a rainbow? What makes rainbows? How does white light change to show so many colors? In this article, we will demonstrate how rainbows are made. We will also explore the characteristics of light. What is the purpose of this article?
to study characteristics of light and understand how rainbows are made
