10. Guided Read  Read with table partner in 6” voice.  Complete study guide in COMPLETE SENTENCES! Write in your own words; it will help you to remember more because you have to think about it! Write in your own words; it will help you to remember more because you have to think about it!

11. Song Time

12. Atomic Theory Polka  Dalton, Thomson, Rutherford and Bohr. Schrödinger and Heisenberg, and many, many more. Used their brains to venture in the realm of inner space and found the world of the atom was a weird and wondrous place.

13.  Dalton did experiments and said, “I think it’s clear, atoms are tiny indestructible spheres.”

14.  Thomson worked with cathode rays and said, “I disagree. A plum-pudding model makes much more sense to me.”

15.  A new chapter in atomic theory started to unfold when Rutherford played around with atoms made of gold. When a few of his alpha particles came bounding back, he hypothesized a nucleus had knocked them off the track.

16.  Dalton, Thomson, Rutherford and Bohr. Schrödinger and Heisenberg, and many, many more. Used their brains to venture in the realm of inner space and found the world of the atom was a weird and wondrous place.

17.  Bohr saw spectral lines for hydrogen and said, “It seems to me.. Electrons move in orbits with specific energies.”

18.  Heisenberg said, “Forget it, there’s no way to know the orbit or a path, where the electron’s gonna go.”

19.  Schrödinger used lots and lots of fancy mathematics, and made a model of the atom based on quantum mechanics. It has orbitals and those are based on probability. The atom is a fuzzy blob of pure uncertainty.

20.  Dalton, Thomson, Rutherford and Bohr. Schrödinger and Heisenberg, and many, many more. Used their brains to venture in the realm of inner space and found the world of the atom was a weird and wondrous place.

21. Atomic Theory Date

22. Democritus  Date 460-370 B.C.  Democritus was a philosopher; did no research  He thought that everything was made up of tiny round things called atoms.  Atoms are the building blocks of life.

23. John Dalton 1787 – 18441787 – 1844 Wanted to learn in what ratios different elements combine in chemical reactions.Wanted to learn in what ratios different elements combine in chemical reactions. Through experimentation devised his atomic theory.Through experimentation devised his atomic theory.

24. Dalton’s Atomic Theory 1. Elements are composed of submicroscopic indivisible particles called atoms. 2. All atoms of a given element are identical. Atoms of different elements are different from one another. 3. Atoms of one element can mix or chemically combine with atoms of other elements, creating compounds with simple whole-number ratios. 4. Chemical reactions occur when atoms are separated, joined or rearrange.
