A Geode Hides Sparkles Inside
Picture a rock that looks plain and gray. It is round and lumpy, a little like a potato. You would not give it a second look. But it has a secret.
This rock is called a geode. When someone cracks it open, a hollow space is inside. The walls of that space are covered with shiny crystals. Some are clear like glass. Some are purple.
How did the crystals get there? The geode started with an empty space inside a rock. Water seeped in, and the water carried tiny bits of minerals. As the water dried up, the minerals were left behind. Slowly, the crystals grew bigger.
This takes a very, very long time. That is why people who study rocks like to look at geodes. They show how patient nature can be.

Here is a rock. It is gray and plain. It is round and lumpy, like a potato. It has a secret.
It is a geode. Crack it open. There is a hollow space inside. The walls have shiny crystals. Some are clear. Some are purple.
How did the crystals get there? The rock had an empty space. Water seeped in. The water had tiny minerals in it. The water dried up. The minerals stayed. They grew into crystals.
It takes a very long time.

Imagine a rock that looks completely ordinary. It is gray, round, and lumpy, a little like a potato, and most people would not give it a second glance. Yet it is hiding a wonderful secret.
This kind of rock is called a geode. When someone carefully cracks it open, a hollow space appears in the middle. The walls of that space are covered with shiny crystals, and some of them are clear as glass while others are purple.
How did the crystals end up inside? The geode began as an empty space within a rock. Water slowly seeped in, carrying tiny bits of minerals along with it. As the water dried up, the minerals were left behind, and over time the crystals grew larger.
This process takes a very, very long time, which is one reason people who study rocks enjoy examining geodes. They show how patient nature can be.

How to use it
Press Read it big (or B) to put the text on the projector, or Full screen (F) to fill the whole screen.
Ask the questions one at a time and use Show answer when the class has decided. A shows or hides every answer.
Print student copy for the class, or Print with answers for yourself.
Ideas for class
Before reading, put geode, crystals, hollow and minerals on the board with their meanings from the Words to know section and have students predict what the text will be about.
Read it aloud once while students follow along, then have them reread it alone or with a partner. At a calm 100 words a minute it takes about 1 minute to read aloud.
Use the Read it big button (or B) to put the text on the projector, and Show answer on one question at a time so the class commits to an answer first.
Question 5 asks the reader to infer. Ask students to point to the words in the passage that led them to their answer.
Ask students to write one question the passage did not answer, then look for the answer in a book or on a classroom screen.
Print the student copy for independent work and keep the answer-key copy for yourself.
