Astra Rocket Workshop - It's a BLAST!

Rocket Launch Day

The Bottle Rocket Launch

A group of senior students are building Astra rockets to explode into the air space over our school on Rocket Launch Day.

The rockets use explosives to blast over a thousand feet into the sky!

The first session was spent constructing the motor mount to hold the motor clip, tying and positioning the shock cords,

gluing everything in place in the body tube. The greatest challenge for the students was overcoming their reluctance

to read the instructions! Join our Workshop and meet Sir Isaac Newton, the man behind the science...

Astra Rocket Assembly Instructions

Flight Event Diagram - How it Works

Sir Isaac Newton (1643 - 1704)

Scientist Sir Isaac Newton was fascinated by how

things move, the behaviour of light, the science of

forces and the nature of gravity.

Newton discovered Three Laws of Motion


Rocket science is based on Newton's Third Law:

For every action there is an equal

and opposite reaction

This means that if you push something one way,

it always pushes back.

Let's get on with it...stop talking... we can always

read the instructions (hmmm.. if only!)

P1280628.JPG

The red centre rings which hold the motor pin and

the shock cords...hmm... how far along the yellow

motor tube does it go... even the Principal must

read the instructions.

Now where does this blue thrust ring go... read

and find out...
