Of course it's a tough question. It's believed for some people the existence of the ninth intelligence. This is the existential intelligence, related to the ability to pose and ponder questions regarding the existence including topics such as life and death. It is for philosophy teachers.
As a Science teacher, mine is the Naturalistic intelligence. It is seen in someone who recognizes and classifies plants, animals, and minerals including a mastery of taxonomies. Also, who recognize specimens and value the unusual. I am aware of species such as the flora and fauna around the world and the environmental issues.
Teachers must use this intelligence or the other ones by using relationships among the students, systems of species, and classification activities. Encouraging the study of relationships such as patterns and order, and compare-and-contrast sets of groups or look at connections to real life and science issues.
Naturalists as Charles Darwin is an example of people gifted in this way.
