Impact helps teenage learners to better understand themselves, each other, and the world they live in.

National Geographic Explorers are featured as role models who embody the 21st century skills and values teenagers need to become successful global citizens.

Cross-curricular topics engage learners with stimulating information about the world, better preparing them for future academic success.

Student choice activities and projects present learners with options for language practice, allowing teens to become active participants in the learning process.

By encouraging self-expression, global citizenship, and active participation, Impact motivates students to explore who they are and who they want to be, all while learning English!

Video Program

Created especially for teenage learners of English, the Impact Video program is fully integrated into each unit of the Student Book. Each unit features two video clips, including:

  • Main Video: the Main Video in each unit introduces a key concept of the unit theme in a unique way, either through live action National Geographic content or through an original animation designed specifically for the Impact program.
  • Meet the Explorer: When students reach the Mission page of each unit, they’ll learn more about the National Geographic Explorer featured in the unit. These short, one-minute clips reinforce unit objectives, develop critical thinking skills, and allow students to hear from each eplorer in his or her own words.

The video program is available on a DVD bound with the Lesson Planner, on the Classroom Presentation Tool, and on the Online Workbook.
