Science student’s book should be in accordance with 21st century learning with assessments that are relevant to the characteristics of the learning. Where in the 21st century learning that is demanded are critical thinking skills and problem solving, creative and innovative skills, communication skills and collaborative skills. Where the four skills will aim to develop the potential in developing character, talent, competency, interest and literacy. To make use of this science student’s book, then need to be validated. The purpose of the validation is to know the validation science student’s books with the theme of energy in life based integrated local materials using integrated models for 21st century learning to use Aiken’s V with 5 validator is three experts and two practitioners composed. The questionnaire used the data of collection method. The result by 3 experts composed of content validation, construct validation, validation and then the graphical language with a valid validation category. While practitioners composed from same 2 with 3 experts composed is content validation, construct validation, validation and then the graphical language with a valid validation category. Conclusion, overall the science student’s books with the theme of energy in life based integrated local materials using integrated models for 21st century learning Be avowed valid and it can to be use in school.
