Blast off!

Engineering activities give kids a chance to develop problem solving and observations skills, to work with interesting and engaging tools and materials, and to learn how to work as a member of a team. In this activity, children get a chance to do all that—and to launch their creations into the air!


These rockets fly a long way, so this activity should be done outdoors or in a gymnasium or cafeteria.

Make a sample rocket to show students later (read all of these instructions for tips). Next, create the rocket launcher. Cut the valve section off of one of the bicycle inner tubes so it is one long open tube (See Figure 1, below).

Slip one end of the inner tube over one end of a piece of PVC pipe, up to about 1 inch. Slip the other end of the inner tube over one end of the tornado tube, up to about 1 inch. Slip 1 hose clamp over the inner tube and PVC pipe, and 1 over the inner tube and tornado tube, and tighten these clamps with a screwdriver. The clamps will hold the inner tube in place on the pipe and tornado tube. You could use duct tape instead of hose clamps, but this makes replacing parts of the rocket launcher a lot harder and messier. Also, this activity can be done without the Tornado Tube, but get it if you can—it makes it much easier to replace broken soda bottles—which will happen occasionally. Your final step in creating the rocket launcher is to screw a soda bottle into the open end of the tornado tube. If you’re not using the tornado tube, you can slip the inner tube over the open end of a soda bottle, then clamp them together with the hose clamp. When you are finished, your rocket launcher will look like this (See Figure 2, below).

Paper Rockets

Suggested Materials

  • Copy paper (50 sheets)
  • 3″ X 5″ index cards (50)
  • Invisible tape (10 rolls)
  • 2 bicycle tire inner tubes (24″; save one in case the first breaks)
  • Tornado Tube (1; optional—see Preparation)
  • 2 hose clamps (1 3/4″ or 2″)
  • 5 pieces of PVC pipe (1″ inner diameter, about 1 5/16″ outer diameter, 12″–18″ long)
  • Empty, clean 2-liter soda bottles (5)
  • Large paper clips, pennies or small washers (100–200)
  • Scissors (10)
  • Flat head screwdriver

Make it Matter

Opening Discussion

Ask your students if they’ve ever seen a rocket before. What does a rocket look like? Have a volunteer draw a rocket on a piece of chart paper or a chalkboard. Is this the shape everyone had in mind? If anyone has another shape in mind, have them draw that shape. Do rockets travel fast or slow? Does the shape have anything to do with that? Can they think of other things that travel fast? What is their shape like?

What do we use rockets for? Show them some NASA images of rockets (there are a few example in Resources, above, to get you started), or videos of rockets, such as these:  .

What do these rockets all have in common? Ask your students to list for you the parts of a rocket. You should write down what they come up with on chart paper, a white board, etc. where everyone can see it. Make sure that a “nose” or “tip” (sometimes called a nose cone), fins, a body, and something about propulsion or “power” are all included on the list. NOTE: Not every rocket has fins or even a nose cone, but for the purposes of this activity, it is good to look at the parts of a rocket and how those parts can impact its performance.

The Challenge

Design, build and launch a rocket that travels as far and as straight as possible.


Make it Happen

Doing the Activity

  1. Divide your class into teams of 3 for this activity.
  2. Tell teams what their challenge is, then show them the materials they’ll have to make their rockets. Each team will have 2 pieces of paper, 2 index cards, 10 paper clips, pennies or small washers, 1 roll of tape and 1 pair of scissors. The extra pieces of PVC are for students to measure their prototypes with—the rockets should just fit around a piece of PVC. Show them how to roll a piece of paper around the PVC to make a cylinder – taping this piece of paper into this shape will create the body of the rocket. Leave the PVC at the front of the room—the “testing facility”—so that teams can come up and make sure that their rockets are the right size. You could also provide a piece of PVC for each team to use at their tables.
  3. Show students the rocket launcher so they can see how they will make their rockets fly, and gently launch your sample rocket. See “Make it Better” for launching instructions.
  4. Build the rockets! If you are doing this activity inside your afterschool classroom, there will be no test launching until you take them to the launch area. Teams will have to throw their rockets to judge how well they will travel. If you are doing the activity outside or in the indoor launching spot, students can bring their prototypes to you to perform test launches (see “Make it Better”, below).

Let’s Talk About It

After 10-15 minutes, when teams have built a first prototype and had a test launch or throw, bring the group together to talk about what they have discovered. What have they added to their rocket to help it fly? Have each team show their rockets to the other teams. Look for teams that have created a closed end at the top of the rocket. How does this help the rocket’s flight? Also look for teams that have added weight to the rocket. How does that help?

Build On What They Talked About

After hearing from each team, send them back to work on their rockets. Most likely, students will have some working prototypes by the end of the session but will not have perfected their rockets. Use the next activity, Paper Rockets – Flying Farther to give them a chance to make their rockets even better.

Ready to launch? Give kids a chance to test their first prototypes at the end of the session. Place the soda bottle on the ground and hold the PVC end up in the air, pointing away from the students at about a 45 degree angle. Make sure all connections on the launcher are tight, the soda bottle is not crushed, and that the tube is not twisted. Each team should come up to you, slip their rocket over the piece of PVC, and step back. Have the class count down from 10 – when they reach 0, they can yell “Fire!” or “Ignition”, etc., while 1 student from the team whose rocket is being launched stomps on the soda bottle. This will force air through the tube and into the rocket. If the rocket has a closed end at the top, it will fly off into the air. If it does not fly—well, that is just a great opportunity to do some problem solving. You may need to “re-inflate” the bottle after each launch. Hold the end of the PVC with your fingers protecting your mouth from touching it, and blow into it to refill the bottle.
