Reflection: Real World Applications Radioactive Decay and Nuclear Waste - Section 1: Launch


It was nice to have our initial conversation for this task because it brought in some knowledge that students have from their chemistry class. Any time that students can see a legitimate connections between two subject matters is an awesome thing! Students were defining isotopes, discussing carbon dating, and nuclear waste.

Later on in the lesson when we work with half-lives, I heard many groups talking about a formula that they learned in chemistry. Some students did not remember the formula but they were able to get the right answer by using mathematical sense-making; it was nice to see that their math skills were more powerful than a memorized formula!
