1. 8 th grade Physical Science Unit 1 Lesson 1-3 Overview

2. Class Connect Structure  All Science class connect sessions will be at 3PM EST (2PM CST)  Weekly Overview Lesson on Monday or Tuesday  Targeted small group sessions for the remainder of the week  If you do not pass your assessment for a lesson you will be required to attend a small group session.

3. Science Journal  Each student needs to have a Science Journal  I recommend having a hard copy instead of a virtual journal. You will need to able to take you journals away from your computer to make observations  All entries must be dated  All entries should also have a topic line  Any type of note book will work, but you need about 100 pages.

4. Unit 1 Overview In this Physical Science course, you will study the following topics in this order: 1. Introduction to Physical Science 2. Matter 3. Chemistry 4. Force and Motion 5. Energy 6. Waves, Sound, and Light 7. Electricity and Magnetism 8. Research Project

5. What is Physical Science?  Watch the following video and the chat examples of Physical Science  http://www.youtube.com/watch?v=LuZTlr ZMN7k http://www.youtube.com/watch?v=LuZTlr ZMN7k

6. Lesson 2 Science Systems  There are two types of systems  Open  Closed

7. Open vs. Closed Systems  What is the difference between an open and closed system?  Is the Earth an open or closed system?  Example of an open system?  Type examples of in chat  What about a fish tank?  Example of a closed system?  Type examples in chat

8. Universal Laws vs Theories  Universal Laws are the same everywhere in the Universe  Example of Gravity  Theory or Theories change over time as new information is learned  Example of Atomic structure

9. Lesson 3 and 4 Measurement and International System (Metric System)  Measuring different things requires different tools  Volume - liters  Mass - grams  Length - meters  Temperature - Celsius or kelvin

10. SI - International System of Units 1. Based on multiples of 10 2. Common metric prefixes : a. mega- (M) 1 000 000 x b. kilo- (k)1 000 x c. hecto- (h) 100 x d. deka- (da) 10 x e. deci- (d)0.1 x(1/10) f. centi- (c) 0.01 x (1/100) g. milli- (m) 0.001 x (1/1000) h. micro- (u) 0.000 000 001 x
