Ballooning along - session 2

Mr. Geekie had stiff, sore knees after cutting all the profiles of your balloons. They are coming on well. Mr Hamshaw-Hart will look at volume calculations next week - an exciting prospect involving some deep maths!

Hot air ..........................balloon, starting the project

Okay here we are again, great to be back. I want everyone to make a hot air balloon - a BIG one which we can launch from school. We will look at air mass and also - using applied mathematics, calculate the volume of the variable shape balloon. This will be particularly interesting. Also we will look at CAD and how we can generate a swept profile thus creating a 3d object as a drawing.

Next meeting is on 19th Jan 2010

Wow 2010 already.
The next session is looking at air density and we aim to start making some hot air balloons, Mr Geekie has made a large form for us to trace around - can anyone tell Mr. Geekie the correct name for this segmented shape???
Hope to see you all soon - Mr. Geekie
