Just finished the chapter on radioactivity with the students. So sad that this chapter is left out in the new syllabus. Very interesting chapter to talk about and teach. Oh well... here's a video for you to enjoy learning about radiation. Haha... in class we had interesting discussions about the radiation killing sperm and eggs, about how radiation causes cancer and we really do not know what is in our foods these few days...
