Physics experiments/activities do not have to be costly in time or resources. Teachers also do not need to limit their equipment purchases to "high tech" or specialty materials sold exclusively through science supply catalogs. Many valuable data collection activities can be performed using inexpensive materials that may be purchased from local department, hardware, and/or toy stores.
The Astophysics package was published in 1997. It was written primarily to support modules currently available in the A level physics syllabuses at that time. Parts of package were also relevant to astronomical topics within International Baccalaureate and GCSE courses as well as to adult and continuing education.
