Science has answers and more questions. The questions of science are often the questions of society. Hands-on, minds on science cannot be taught without asking hard questions. Frequently a science program that encourages students to think also encourages questions. The questions are not for the teacher, however, to answer.
Students can apply similar methods to collect information and ferret out sound data.
Encouraging students to discuss the issues at home as well as at school helps too. Parents want and need to be involved. Children deserve opportunities to study, to understand, to reach conclusions about issues, even controversial ones. These values draw people together rather than separate them. Technology often is the product of science.
