  10. TURN IN YOUR BELLRINGER!

  11. November 16, 2009 AGENDA: 1 – Quick Chem and Discussion 2 – Notes on Science Fair Report. 3 – Get on the computer and work on science fair Today’s Goal: • To know what is needed in your science fair report. • HOMEWORK: 1. BOHR Model Homework 2. Science Fair Topic, Procedures and Materials

  12. Science Fair Report Ms. Barkume 11/16

  13. Science Fair Report Ms. Barkume 11/16

  14. Scientific Understanding of the Nature of Light 1900-present

  15. Wavelength of Light Radio waves are longer than a football field, while gamma radiation wavelengths are smaller than an atom

  16. Electromagnetic Spectrum

  17. Quantized EnergyMax Planck (1900) • Studied why hot metals glow • Determined that energy is transferred in little packets of energy called a quantum of energy • Think of heating up a substance increasing not as continuous energy, but as rising up little stair steps of energy.

  18. The Photoelectric EffectAlbert Einstein (1905) • Determined that light should be considered to act more like a particle than a wave. • Think of turning a light source on and off so fast that only one single particle of light is released—that is a photon.

  19. Visible Light Niels Bohr (1913) • Create a model that explained that light is produced when an electron is excited to another energy level and then returns to its original position, giving off light. • His model only worked for hydrogen, but it opened up the idea that there are various energy levels where an electron can be located.

  20. De Broglie and Heisenberg (~1925) • Proved mathematically that you cannot determine the exact location of an electron. • Became known as the “uncertainty principle.”

  21. Schrödinger Wave Equation (1926) • Created an equation that takes into consideration that light acts as a wave and a particle at the same time. • His equation determined the probability of where an electron can be found around a nucleus

  22. Orbitals based on Shrödinger’s Wave Equation

  23. Bohr Model Homework

  24. Radioactive Decay of M&M-iums

  25. Calculate Average Atomic Mass • Start your homework! • Calculate the average atomic mass of Copper. It has two isotopes • Cu-63 69.2% Abundance, Mass of 62.930 amu • Cu-65 30.8% Abundance, Mass of 64.928 amu

  26. Calculate the # Protons, Neutrons, and Electrons • Fe • Na • Hg • Cl • 51Hg We will check it together in class.

  27. ToonDoo Activity • Login to computer: user: school, password: Student! • Open IE or Firefox, and go to www.toondoo.com • In the top right corner, click on register. • Create user name, password, and put in an email address (if you don’t have one, use cps email) • Once you are logged in, go to Tools, ToonDoo Maker • Make a cartoon of an atom of an element (pick an element in the second row of periodic table) • In your cartoon you must include • # protons located in a nucleus • # neutrons located in a nucleus • # electrons located around the nucleus • Bonus points will be awarded to any creativity added to the toon (ie, research what the element is used for, and include that in the cartoon.)
