(b)(i) Part of any (A) book or material obtained prior to July 19, 2024, (B) geographic information system, or (C) computer program that renders a three-dimensional representation of Earth based primarily on satellite imagery, such as Google Earth or similar software; and

(ii) A Gall-Peters projection map or a similar cylindrical equal-area projection map or an AuthaGraph projection map is displayed in the classroom or shown to students during the lesson in which a Mercator projection map is used.

(3) Nothing in this section shall be construed to require a school to dispose of or replace any book or material used in the classroom or obtained prior to July 19, 2024.

(4) The school board of each public school district shall adopt a policy to implement the requirements of this section.
