Chapter 1 test Study Guide

-Organization of Human Body

-The Skin

-The Skeletal System

-The Muscular System

-Diagnosing Bone Diseases

Key Concepts

• The      levels of organization in the body consist of cells, tissues, organs, and      organ systems.
• Homeostasis      is the process by which an organism’s internal environment is kept stable      in spite of changes in the external environment.

Key Terms

• cell,cell      membrane, nucleus,      cytoplasm,      tissue,      muscle      tissue, nervous      tissue, connective      tissue, epithelial      tissue, organ,      organ      system, homeostasis,      stress

Key Concepts

• Your      skeleton provides shape and support, enables you to move, protects your      organs, produces blood cells, and stores minerals and other materials      until your body needs them.
• Joints      allow bones to move in different ways.
• Bones      are complex living structures that undergo growth and development.
• A      balanced diet and regular exercise are important for a lifetime of healthy      bones.

Key Terms

• skeleton,      vertebrae,      joint,      ligament,      cartilage,      compact      bone, spongy      bone
• marrow,      osteoporosis

Diagnosing Bone and Joint Injuries

Key Concepts

• Three      common skeletal system injuries are fractures, dislocations, and sprains.      Two ways to identify skeletal injuries are X-rays and magnetic resonance      imaging (MRI).
• Ways      to treat skeletal injuries include wearing a cast, joint replacement, and      arthroscopy.

Key Terms

• fracture,      dislocation      sprain      X-ray,      magnetic      resonance imaging
• arthritis,      arthroscope

The Muscular System

Key Concepts

• Your      body has three types of muscle tissue—skeletal, smooth, and cardiac.
• Skeletal      muscles work in pairs. While one muscle contracts, the other muscle in the      pair relaxes to its original length.

Key Terms

• involuntary      muscle, voluntary      muscle, skeletal      muscle, tendon,      striated      muscle, smooth      muscle, cardiac      muscle

The Skin

Key Concepts

• The      skin has several functions: protection, maintaining temperature,      eliminating wastes, gathering information, and making vitamin D.
• The      two skin layers are epidermis and dermis.
• Three      simple habits can help you keep your skin healthy. Eat a healthful diet.      Keep your skin clean and dry. Limit your sun exposure.

Key Terms

• epidermis,      melanin,      dermis,      pore,      follicle,      cancer

Hi Parents and students,

We are done with Forces , Motion and Energy. Now we are moving to Human Biology and Health.

Couple things to note:

Please return the Forces ,Motion and Energy Textbook if you signed one .They are due in Friday 11/9/13 to avoid paying the obligation.

Also encourage student to sign out book if they can't get access from home. the new code is : cae 0615

Please encourage your child to review his/her textbook/notes /worksheets daily to keep up with the new vocabulary and concepts.

Keep working hard as always!

Here is the study guide. Students were given a hard copy on 10/17

Test 3 Study Guide and review questions

A very Good luck to you !

Chapter 4 Pages 106-141

Work and Machines

Be able to define the following vocabulary:  

work: Force times distance, force exerted on an object that causes it to move in the same direction 

Work’s unit is the joule (J) or  Newton*meter (N*m)                                                      

machine: a device that makes work easier by changing the force, the

               distance, or the direction.               

input force (effort):the force you exert on the machine       

output force (load):  The force the machine exerts on another object

input work: The work you put into a machine,  (Input force * input distance)                              

output work: The work the machine does on another object

mechanical advantage (MA): output force divided by input force

 the # of times force is increased or decreased         

(MA has no unit.  It can be calculated with force or distance)

            IMA= ideal mechanical advantage (No work is lost due to friction, efficiency =100%)

            AMA= actual mechanical advantage (MA of a machine in the real world, efficiency <100%)

efficiency: output work divided by input work times 100%    (Given as a %)

Simple Machines:                              

  a. inclined plane: a flat, sloped surface  (ramp)                 

  b. wedge: an inclined plane that moves       (knife blade)                                

  c. screw:  an inclined plane wrapped around a screw to form a spiral

  d. lever: A simple machine made of a rigid bar that pivots around a fixed point (fulcrum)             

(1^stclass):   Fulcrum is in the middle between the input force and output force (see-saw)

(2^nd class): Output force is in the middle between the input force and fulcrum  (wheelbarrow)

(3^rd class): Input force is in the middle between the output force and fulcrum  (hockey stick)                   

  e. wheel and axle: two attached circular or cylindrical objects (of different radius)  that rotate around a common axis      (screwdriver)

  f. pulley : a grooved wheel with a rope or cable wrapped around it  (block and tackle)

gear:  A toothed wheel designed to mesh with, and turn, another gear.  Teeth are called cogs.

The two systems are the spur gear (both gears on same plane) and crown gear (90^o apart)          

compound machine: a machine made up of two or more connected simple machines

Be able to:                                                                                                                                                

1. Identify when work is done on an object and that there is no work without motion. 

            Work: The motion is in the same direction as the force.

            No work: The object doesn’t move or motion is not in the same                                              direction as the force.

1. Give examples of the 3 ways that machines make work easier.

changing force: A screwdriver puts out more force than we put in by turning the handle.

changing the distance: A hockey stick hits a puck farther from the fulcrum than your hand

changing the direction: We pull down on a single fixed pulley to raise a weight

1. Know that the work you put into a machine (input work) equals the work you get out of the machine (output work).

Force and distance are inversely related.  When one increases,  the other decreases.

Find a machine’s input and output forces and directions. Draw arrows to show the input force and output force in each case.  Know that FD = FD, (work in = work out).

List the six simple machines learned about in this chapter.

What is the formula used to find work?

What is the formula used to find power?

What are the SI units of power and work?

What is the formula used to find actual mechanical advantage?

How can you increase the mechanical advantage of an inclined plane or wedge?

What is a major force that reduces the efficiency of a machine?

What type of simple machine is used to raise a flag up a pole?

What types of simple machines are used by furniture movers to help load a truck?

What two machines’ mechanical advantage increases when they become longer and thinner?

A baseball bat is an example of what type of simple machine?

Is an apple peeler/corer a simple or compound machine?  Why?

Why can’t a machine have efficiency greater than 100%?

Dear Parents,

Please check students agenda books for homework regularly. They are supposed to be using the agenda books to record homework. To ensure that it is authentic, let students bring their agenda books for signatures.

Usually class work becomes home work when it is not completed in class.

lets keep the partnership going!
