#3.8 Aim: Where does nuclear energy come from? Agenda QOD (10) Activity: Nuclear energy (15) Lesson: Nuclear energy (15) Summary (5) No HW Nuclear energy The energy that holds atoms together. How do we all use oil in our every-day lives?

#3.8 Aim: Where does nuclear energy come from? Agenda QOD (10) Activity: Nuclear energy (15) Lesson: Nuclear energy (15) Summary (5) No HW 2. These split apart and produce more neutrons… 3.…which then collide with other heavy, unstable atoms, and the process continues. How does nuclear fission work? 1. Neutrons are fired at heavy, unstable atoms.

#3.8 Aim: Where does nuclear energy come from? Agenda QOD (10) Activity: Nuclear energy (15) Lesson: Nuclear energy (15) Summary (5) No HW Using this chain-reaction with control gives us nuclear power Using this chain-reaction uncontrolled gives us a nuclear bomb
