Aim: Where does nuclear energy come from? Agenda QOD (10) Activity: Nuclear energy (15) Lesson: Nuclear energy (15) Summary (5) No HW Nuclear energy QOD: How do you think our country and our lives might change with our new President?

Aim: Where does nuclear energy come from? Agenda QOD (10) Activity: Nuclear energy (15) Lesson: Nuclear energy (15) Summary (5) No HW Nuclear energy Look at the 11 newspaper headlines at your table. Start a written conversation answering either of the following: a. Do you think nuclear power is good or bad? Why? b. Do you think nuclear power is worth using? Why? After 90 seconds, you will pass your conversations to the left and respond to someone else…

Aim: Where does nuclear energy come from? Agenda QOD (10) Activity: Nuclear energy (15) Lesson: Nuclear energy (15) Summary (5) No HW Objectives **SWBAT describe nuclear energy **SWBAT describe nuclear fission

5 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 potential energy within the nucleus of an atom. The forces that hold together the nucleus of an atom are more than 1 million times stronger than the chemical bonds between atoms. 5

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. Makes up about 15% of the world’s energy!

8 Aim: Where does nuclear energy come from? Agenda QOD (10) Activity: Nuclear energy (15) Lesson: Nuclear energy (15) Summary (5) No HW Nuclear Fission A process by which the nucleus of a heavy atom splits into 2 or more fragments. A chain reaction

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.
