50 free Bill Nye the Science Guy trivia questions with answers — trivia quiz, new questions added Oct 2026.
Bill Nye the Science Guy made a generation of 1990s kids believe that science was the best part of the school day. Across one hundred fast, funny half-hours, a bow-tied host in a lab coat ran experiments, cracked jokes and spoofed chart hits, and the series collected nineteen Emmy Awards along the way. This quiz covers both halves of the story. Some questions are about the man and the making of the show: where he came from, how the character was born on local television, and what he did next. The rest follow the episodes teachers still play in class, including Food Web, Magnetism, Respiration, Bones & Muscles, Digestion, Earth's Crust, Flowers, Germs, Phases of Matter, Planets & Moons and Cells, plus the scientific method. It works as a review after one of the videos, a warm-up for science class, or a nostalgia test for anyone who grew up with the theme song stuck in their head. Every answer comes with a short explanation, so nobody leaves without learning something.
