Sharon,
as you have noted, spaceweek.ie hosts resources for teachers to use in the classroom and also family activities and club activities.
Make a Spacecraft is presented as a family activity, so you may want to review which parts of the curriculum you intend it to support.
To review how rockets have changed over time, see the resource from the NASA rocket educators guide: https://www.nasa.gov/wp-content/uploads/2012/03/rockets-guide-20-history.pdf?emrc=231d29
There is also a powerpoint on scoilnet, that is sourced from http://www.spacekids.co.uk/spacehistory.
