I love online quizzes. Here's one that taught me a thing or two about what is considered a hazardous material and what is safe to throw away in the trash. This quiz from Learner.org tests your knowledge of waste disposal guidelines. Decide whether the item shown (such as paint or prescription drugs) is: hazardous, recyclable, able to be disposed of with the regular household trash or able to be washed down the drain. The quiz is based on typical U.S. waste disposal guidelines, but all communities have their own rules and regulations. Check with your local town or city hall for specific information about your community.
