TRUMP Part 2: Observational Properties of Astronomical Objects

Part 2 of the TRUMP Astrophysics resource package dealt with the observational properties of astronomical objects and was therefore concerned with the analysis and interpretation of observations.

Like Part 1 of the TRUMP package, this part contained study notes (self-study material for teachers), teaching notes and photocopiable student sheets to support a range of student activities.
