Part of Lesson Plan: This Means This This Means That Part 1
Activity Overview / Details
Project the attached danger sign. Ask the students to imagine that they have to tell someone living 2,000 years from now about a danger that exists today. Commercial nuclear reprocessing has ensured that thousands of gallons of radioactive liquid will be active in thousands, perhaps hundreds of thousands, of years to come. And if we don't tell future generations where and how we stored this waste, they may be exposed to it without suspecting that it is highly toxic.
Have the students consider the design carefully and, first, think about whether or not it will be effective in the future.
Ask them to sketch a danger sign for radioactive material that might be more effective.
