Tour guide or a traveler’s guide Imagine you are a pesticide, sewage, or toxic waste particle. You are looking to do some traveling. Once you are released from your container, toilet, storm drain, or battery where do you go? Create a travel brochure that explains where toxins can go and the impact they can have on their environment. Don’t forget to mention how humans can dispose of you responsibly and destroy your travel plans. 2. Kids story book Tell the story of your topic in a kid’s fiction or non fiction story book. 3.
