Build a Rocket, Page 1

ASTRONAUTICS

OBJECTIVE: Design and construct a rocket that will operate with at least 70% accuracy

MATERIALS: The following materials that will be used in this project can be found in the student bin:
- 2 3/4" BT-20 engine tube - Engine guard clip - 6" elastic shock cord - 9" BT-50 body tube - screw eye - parachute material	- nose cone - 1/2" wide note card stock - 1" wide note card stock - 9" x 3" balsa fin material - 1" straw launch lug

NOTE: You will need to supply your own notebook paper for this project. The sandpaper will be supplied by your instructor.

The following material and equipment will be supplied in the module bin at the given work station:
- 12" ruler - X-acto knife - Pair scissors - Cutting mat - 1/8" wide masking tape	- Elmer's school glue or similar type glue - clear tape - spool thread - fin holder

DIRECTIONS:

1. Put a notch in the small tube 2 1/2" from one end.

Put glue on one half of the engine guard, and place that end into the notch in the tube. Cut a strip of paper, 3/4" x 8 1/2". Wrap and glue this paper around the tube and over the engine guard just below the notch. This will hold the engine guard in place.

2. Now wrap tape around the tube (near each end) so that the thickness of the tape will hold the tube inside the larger body tube. Cut the tape over the engine guard so that the guard can bend easily.

3. Apply glue to all of the edges of the tape on the engine holder. Make sure the glue fills the space inside the edge of the tape. Smear glue on the surface of the outer rings of the tape. Slide the entire engine holder into the bottom of the body tube.

NOTE: The guard should stick out from the bottom of the body tube, and should be easily reached.
