1 This week’s HW: Force, Work, and Simple Machines – Due Friday
Sept. 9th, 2013 DO NOW (Pg. 6 in journal) Cedillo Objective SWBAT define and explain force and work. Prompt What does the word ‘work’ mean to you? Reminders: --Write HW in agenda! --Sharpen pencils and have materials out and ready *BEFORE* bell rings --Be in seat with voice level 0 when bell rings This week’s HW: Force, Work, and Simple Machines – Due Friday

2 ESSENTIAL QUESTION: What is work and how is it related to force? OBJECTIVES: -Define and explain work and force -Identify how work and force are related

3 Work and Force Introduction to work-- Brainpop: Work After Video – Pair Share: Now, how would you describe work?

4 Partner Read 146-147 While Reading:
Complete Frayer Models for work and force on page 11 of your journal: Reading Expectations: ---Both partners read ---Partner with closest birthday reads first ---Voice levels 1 (only partner can hear you) D Definition (include formula & units) Example (Drawing) Vocabulary Word Non-Example Connection to Biology

5 Let’s Review ESSENTIAL QUESTION:
What is work and how is it related to force? OBJECTIVES: -Review Classroom Procedures and Expectations -Define work and examples of work.

6 Experimental Investigation review (pg. 9)
Let’s think about how we could design an experiment about WORK! Fill in your FRAME with your table. Remember: IV – the variable YOU change DV – the variable that depends on the IV and changes because of it Constants – things you would keep the same in each trial of your experiment Control – a comparison experiment in which you do not apply the IV

7 This week’s HW: Force, Work, and Simple Machines – Due Friday
Sept. 10th, 2013 DO NOW (Pg. 6 in journal) Cedillo Objective SWBAT model, measure, and calculate work. Prompt What is the formula for work, and what units is work measured in? Reminders: --Sit in assigned seat --Sharpen pencils and have materials out and ready *BEFORE* bell rings --Be in seat with voice level 0 when bell rings This week’s HW: Force, Work, and Simple Machines – Due Friday

8 ESSENTIAL QUESTION: What is work and how is it related to force? OBJECTIVES: -Model work being done and not being done. -Learn to use a SPRING SCALE to measure force and calculate WORK.

9 Doing WORK? Lift the book at your table straight out in front of you. -Could you feel your muscles working? -Did you use force to get the books straight out in front of you? Did you use force to keep them there? -Did you do work to get them out in front of you? Did you do work to keep them there? Explain? REMEMBER: Work is done on an object when an applied force moves it through a distance in the direction of the force.

11 Work and Human Body Lab PART 2 Work = Force X Distance

12 Let’s Review ESSENTIAL QUESTION:
What is work and how is it related to force? OBJECTIVES: -Model work being done and not being done. -Learn to use a SPRING SCALE to measure force and calculate WORK.

13 DO NOW Date: 1/9 Q: How do simple machines affect force when doing work? Look at the picture, if you wanted to get the object into the back of the truck, what tool could you use to reduce the amount of force needed?

14 ESSENTIAL QUESTION: How do simple machines affect force when doing work? OBJECTIVES: -Students will investigate the effects of inclined planes on force and work.

15 Inclined Plane Lab A:Recorder B: Time Keeper C: Lab Director D: Materials Manager VOICE LEVEL: 3

16 Inclined Plane Lab Debrief

17 Inclined Planes Brain Pop- Inclined Plane

18 Exit Ticket: Quick Write
Quick Write: Explain to the movers why using a ramp to help them load the truck will help get the job done. USE COMPLETE SENTENCES INCLUDE THE FOLLOWING WORDS: Inclined plane, work, force, direction

19 Let’s Review ESSENTIAL QUESTION:
How do simple machines affect force when doing work? OBJECTIVES: -Students will investigate the effects of inclined planes on force and work.

20 DO NOW Date: 1/11 Q: What is the relationship between work and force? Describe a situation where work is being done.  How do you know work is being done? What body systems are involved?

21 ESSENTIAL QUESTION: What is the relationship between work and force? OBJECTIVES: -Grade Homework -Demonstrate our understanding of work using “Top Ten”
