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?

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
