Conceptual+Sept+Cal


 * Conceptual Physics Calendar Day 2 Block A **
 * September 18 **
 * Warm-up – Conversions. (5 minutes)
 * How many meters in one km?
 * How many cm in 1 m?
 * How many seconds in 1 hour?
 * Convert 800 m to miles, 27m/s to miles per hour.


 * Objective: ** Students will use measurements of mass and length to make predictions about unknown quantities. Students will use this information to write a formal lab report and it will be graded using the district lab-grading rubric.

// This will end our review of math and measurements. We will continue to use and develop student ability in the areas of using exponents, algebra manipulation, measurement, estimating, and conversion from one unit to another. //

**HW**: Reports are due on Sept 20th. Be prepared to review each others reports.

=** September 20 **= References: Conceptual Physics Ch 2 Mechanical Equilibrium

Warm-up: 5 lines: Define a force. Describe what a force does. Give examples of different types of forces. Read p 12 intro.


 * 2.1 Force **
 * 1) Discover activity: p12 Hewitt text
 * 2) Materials: Rope, 3 students
 * 3) 2 people pull in a tug of war fashion while a small person pushes down with one small finger. Answer the questions on p12.
 * 4) Discuss what is a force and its units. Differentiate between an applied force and a net force. Differentiate between tension and compression. Draw free body diagrams. Using Concept development p3-6, Text reference
 * 5) Electronic balance Demo 2
 * 6) meter stick weights, What happens as the mass moves from one side to the other.
 * 7) Differentiate between vector and scalar quantities.

Complete p 3 and 4 of the worksheet. Take notes Ch 2.2
 * HW **


 * September 24 **
 * Objectives for week 24-28: **
 * ** Distinguish between force and net force **
 * ** Describe the equilibrium rule and give examples **
 * ** Distinguish between support force and weight. **

Tight rope demo: 2 students pull on rope tight 1 student pushes down in center. discussion

Review Concepts of force, net force, and equilibrium. Students answer questions from Ch 2 Equilibrium
 * p 24 Review Concepts #1-20 all
 * p25 Think and Rank #21-24 all (minimum at end of class)
 * p 25-26 Think and Explain #28, 29, 30, 31, 34, 39 Complete for HW

Next time question:

Equilibrium and Vectors - Review Car Problem.
 * September 27 **

Demo scales and mass change angles. Use protractor and ruler to find the resultant of 2 vectors. Find resultant vector or equilibrant vector.

Assignment: Practice worksheet Vectors p5 & 6 complete in class. Text book: Think and Solve #42-48 all, p 844 1-8 skip 6 to be turned in.

Test on Ch 2 October 1
Review terms, concepts, be able to find equilibrium force, net force, differentiate scalar and vector qty, conditions of equilibrium static and dynamic.


 * October 1 **

Test on Ch 2 October 1

 * Ch 3 Read and take notes on ch 3 in class, outlines due next class. **

Students to research Aristotle, Copernicus, Galileo, and Newton. Create a poster with time a timeline of their lives, popular beliefs of the time, and there contributions to science and our understanding of motion. Include drawings, images etc of relevant concepts.

Who are they? When did they live? What were the belief systems of the time period? What tools did they have to make measurements and predictions about their environment? What is their contribution to our understanding of motion. Examples? Due October 5.

Objective:Students will differentiate between mass, volume and weight. Identify the units of each. Describe motion in general.
 * October 3 **
 * Newton’s First Law of Motion **

Discover activity on P28 warm up. Answer questions in journal, share out.

What is mass? How can motion be accurately described? Are we moving? how can one tell? What is Inertia? State Newton’s 1st Law of motion in your own words.
