We studied about many types of teaching aids and the most important two are :

1) Specimens

2) Models

Specimens is the native teaching aid. They use real or modified tools. It helps the students to experience the real-world tools and improve their knowledge. Specimens must be collated, stored and maintained, which can be cumbersome.  However, they tend to be very beneficial to student learning.

Models are the second aid after specimens ,because sometimes it is hard to find specimens

Or Illegal, immoral, dangerous, etc. specimens. Also, the characteristics of the models are can be constructed and can be purchased, but tend to be expensive.
