Exploring what students are replicating
Step 0 - Bottle rockets
Introduction to the engine
Introduction to the project :
Using a alcohol mix, show students how the fuel works.
Slow motion : introduce students to the concept of Newtons third law.
(You can see the reactant firing out the back)
Step 1 - Which bottle ?
Which bottle is best
Students bring in their own bottle, and we experimentally look at which bottle is best
Students rate the bottle based on power, durability (does it melt) etc.
Step 2 - Which FUEL ?
Methane Vs Alcohol
After much debate, we decided that perhaps alcohol would be safer
As the methane rockets would probably blow our cars apart.
Step 3 - Which Nozzel ?
Devolping the perfect nozzel.
It was decided that the students wanted to be creative, in order to experiment.
Step 5 - Design
Looking at scaling up
Step 6 - Build
Using plaster of paris to build a supporting structure for the vaccum forming machine....
Step 7 - Building (negating the vaccum forming)
Vaccum forming was not really working so we decided to build with materials that we have
