Tell students: "We measure our rate of speed in a car in miles per hour.
This method of measuring a rate won't work for radioactive decay.
Also, return to the questions you asked in the introduction to the lesson and allow students to revise their answers.
Before the lesson, you will have to weigh out about 80 candies for each group of students.
If you count ten and weigh them, then multiply by 8, you will know how many grams of candy to weigh out for each group.
If you lived in a city where there had been a nuclear accident, you and your family might be exposed to strontium-90, which is the principal health hazard in radioactive fallout because it can easily get into the water supply or milk and then be ingested by people.
Write about how the strontium-90 might accumulate in your body (teeth and bones) and how it might affect you.
