Math and Science

Reminder that there is a Math Chapter Test on Graphing Linear Equations on Tuesday April 30th, and that those in Science have their Bohr Models due as well.

Electricity Unit

We will begin to study Electricity in this unit. To begin with you will notice that Electricity build upon what we learned about the Atom and Electrons. Begin by reading about the Electrical Nature of Matter on pages 272- 273 of the text book. Complete questions 1-4.

Next complete the following worksheet.

The Nature of Electricity

Science Chapter Review- Matter and Elements

Review Chapter 3

Timeline of our understanding of elements pg 82-85

Democritus proposed that the smallest indivisible amount of matter that still retained the properties of that substance was an atom.

Alchemists: mixture of science and witchcraft. Tried to change lead into gold. Failed

Dalton: First to recognize Oxygen as an element. Believed every element had its own kind of atoms.

Thomson: Believed that the atom was made up of charged particles. Negative electrons were interspersed throughout the positive Nucleus. Kind of like a "Plum Pudding".

Rutherford: Believed that the Atom was mostly empty space. With a small compact Nucleus and electrons orbiting like planets.

Bohr: Created a model of the atom with a nucleus with Protons and Neutrons and a series of Electron orbiting around the nucleus.
