Rocket Stages Drop Away Like Empty Boxes

A rocket has to carry a lot of fuel to reach space. Most of the rocket is just fuel tanks. The rocket burns the fuel very fast, and the weight of the fuel is a big problem. Every pound the rocket carries makes it harder to climb.

Engineers came up with a smart solution. They build a rocket in parts, called stages. The first stage sits at the bottom. It has the biggest engines and the most fuel. It lifts the whole rocket off the ground and pushes it up through the thick air.

When the first stage runs out of fuel, it is empty and heavy. So it lets go and falls away. Now the rest of the rocket is lighter. The second stage lights its own engines and keeps going.

It is like carrying a stack of boxes. If you drop each empty box when you are done with it, your load gets lighter and lighter. A lighter rocket can speed up faster.

For many years, stages fell into the sea and were lost. Today some stages can turn around and land gently. Then they can fly again.

To escape Earth's pull and reach space, a rocket must carry an enormous quantity of fuel. In fact, most of a rocket is nothing but fuel tanks. The rocket burns this fuel at a tremendous rate, and the weight of the fuel creates a serious problem, since every extra pound makes the climb harder.

Engineers devised an ingenious solution: they build a rocket in sections, called stages. The first stage sits at the bottom and holds the biggest engines and the most fuel. It lifts the entire rocket off the ground and drives it upward through the thick air.

Once the first stage has used up its fuel, it is empty and heavy, so it separates and falls away. The remainder of the rocket is now much lighter. The second stage ignites its own engines and continues the journey.

It is like carrying a tall stack of boxes. If you discard each empty box as soon as you are finished with it, your load grows lighter and lighter. A lighter rocket is able to accelerate faster.

For many years, discarded stages fell into the sea and were lost. Today some stages can turn around and land gently, so that they can fly again.

How to use it

  1. Press Read it big (or B) to put the text on the projector, or Full screen (F) to fill the whole screen.
  2. Ask the questions one at a time and use Show answer when the class has decided. A shows or hides every answer.
  3. Print student copy for the class, or Print with answers for yourself.

Ideas for class

  • Before reading, put fuel, stages, engineers, engines and load 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 2 minutes 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 6 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.
