AP Connections with the Student Video Contest

Students in Advanced Placement classes will gain key skills and essential knowledge by participating in the World of 8 Billion video competition. The contest is a fabulous project for AP Human Geography and AP Environmental Science, as well as AP Biology.

Below we’ve listed the Units and Topics from the APHG, APES and AP Bio frameworks that are covered by the three 2025-2026 topics: Energy, Wetlands, and Economics. You’ll find a PDF under each course that includes the specific Essential Knowledge from your CED.
