Unit 2 – Nuclear Chemistry

Day 1 (Friday Feb 17) – Wrap up Acids & Bases with a report from each group summarizing results & findings.  There is also an individual report assigned (see report instructions)  Introduce nuclear chemistry.  Video: Fusion is Energy’s Future.  Discussion: what do you already know about the atom?  Wrap up with video: Large Hadron Collider.  Reading assignment: Chapter 8 & 9 in Heath: Chemistry.

Day 2 (Tuesday Feb 21) – Each group reported their findings from the Titration Curves Lab.  Continued discussion of Nuclear Chemistry.  Reviewed history of atomic theory including Democritus, “other” early Greek philosophers, Dalton… Ended with key piece of new information: AN ACCELERATING CHARGED PARTICLE PRODUCES A MAGNETIC FIELD.   Beams produced from electrocuting gases deflected when near magnets so they must have charged particles.  This is MUCH more significant than you would think – the gases themselves were neutral so if the beam was charged, that meant the atom had broken down into a + charge and a – charge.  Atoms are made of even SMALLER particles!  Thus, the electron was discovered.

Day 3 (Wednesday Feb 22)  Nuclear chemistry is not just about protons, neutrons and electrons.  Nuclear chemistry is a fundamental part of modern medicine and pharmacology.  Mini research paper assigned.  Reading assignment: continue reading chapters 8 and 9.

Day 4 (Friday Feb 24) –

Day 5 (Tuesday Feb 28) -Sub.

Day 6 (Wednesday Feb 29) – Work on presentations for nuclear chemistry.

Day 7 (Friday March 2) -Class presentations on Nuclear Chemistry.

Day 8 (Tuesday March 6) -Fake pop quiz on Nuclear Chemistry.  Continue with class presentations.  PPT on radioactivity.  Next class we will have “real” quiz.

Day 9 (Wednesday March 7) – Quiz.  Nuclear chemistry papers due.
