Science Project

Senior1 Science Project - Astronomy
"The Solar System – Part 1"

 
In this project, you will be required to research trivia information for each of the planets in our solar system as seen / discussed in class or as researched from some other source.  This must include "at least" two interesting and unique facts about each planet that makes it different than any other planet.  For the purpose of this project, Pluto WILL NOT be included.
 
You need to include a simple title page for your project that contains the name of the project, your name and a simple picture of some sort. (Note: no pictures are required inside your project but they won't hurt.) Add a page with your sources.
 
Your project requires and will be marked on the following:
 
         A)  Project Presentation (not a PowerPoint, unless that is what you want) (appeal, originality and design)                4marks

         B)  Planet Info  (8 x 2)                                   16marks
 
 
Due:             Thursday,June 6, 2013
 
Value:         20 marks

Science

This next unit is about our Solar System. Please read pages 438-439 and do
questions 1-6 (skip 5). Then read pages 444-445, and do questions 1-6
(skip 5).

Science Electricity and Circuits

Homework:

Read pages 300 to 303 of the text.
Complete questions 1-5 , 7 on page 301 and
1-4 on page 303

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

Visit the following site and find the answers to the questions:

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.
