  11. First some background: everything is made of atoms – including this pencil Wood No. 2 magnified 10 times

  12. Cells The wood is made of cells magnified 1000 times

  13. Cells have parts inside them, like DNA DNA magnified 10,000,000 times

  14. DNA and everything else are made of atoms Atoms magnified 50,000,000 times O C C H C C H

  15. Atoms are made of a few parts: protons, electrons, and neutrons N N N P P P E E E O C C H C C H

  16. The protons and neutrons are stuck together in the center of the atom; this center is called the nucleus. There is a lot of space between electrons and the nucleus. N N N N P P P P E E E E The basic parts of an atom Key Neutron (0) Proton (+) Electron (-) The electrons spin around the outside of the nucleus.

  17. If you break an atom’s nucleus apart, it gives off some heat energy N N N N N N P P P P P P

  18. If you break an atom’s nucleus apart, it gives off some heat energy Neutron “bullet” N N N N N N N P P P P P P

  19. When you break apart a large atom like uranium, 3 neutrons get separated N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N P P P P P P P P P P P P P P P P P P P P P P P P P P P P P P P

  21. This is called a nuclear chain reaction It makes a lot of heat ! !
