The American Heritage® Student Science Dictionary Editors Have Devised A Fun and Informative Test of Science Literacy

With science literacy in the United States on the slide, the editors of The American Heritage® Student Science Dictionary have developed a science quiz to help students and their parents evaluate how science savvy they are. In sixteen short multiple-choice questions, kids and adults can test themselves — and one another.

"We hope that students, their parents, and teachers will sit down and take the quiz together," says The American Heritage® Student Science Dictionary project editor Vali Tamm. "We couldn't cover all areas of science in such a short quiz, but hope this test will motivate students and adults to improve their knowledge of science, and help them develop the skills for finding the answers they might not know."
