Firstly, in Australia a licence or a permit is required to possess or use a firearm, and this is regulated in each state/territory1. For example, in NSW an air rifle is regarded as a Category A firearm2, a genuine reason for owning and using a firearm is required3 and this must also be registered with the Commissioner of Police4. Further information for NSW can be found here: https://www.police.nsw.gov.au/online_services/firearms/firearms_and_ammu.... Other states should consult their regulators.
Secondly, this is an extremely high-risk activity5,6. Managing the risks would require strict controls in place to manage the safety, security and legal requirements. (E.g. safe procedures; staff training; regular maintenance; secure storage; licencing and registration). In addition, we are not sure that a demonstration of the velocity of a bullet would qualify as a valid reason for schools to obtain a licence to possess and use a BB pump rifle.
The safety risks regarding the use of air rifles/ BB guns far outweigh the educational benefits. There are suitable and much safer alternatives to support the curriculum.
Science ASSIST recommends that the best risk management strategy is to substitute with a less hazardous activity. A standard projectile launcher, with appropriate safety controls in place, would be a suitable alternative. These are available from scientific suppliers, see our list of School science suppliers.
We strongly advise that schools use safer activities for demonstrating and measuring velocity. Each activity would require a site-specific risk assessment and safety glasses are essential for all practical activities using projectiles. Here are some examples:

A word of caution: We are aware that some schools may be using NERF guns. The darts are made from foam but are still capable of causing serious eye damage, so safety glasses MUST be worn. Science ASSIST strongly advises against any modification of NERF guns7.
