  • In this module we will learn about work and energy.  


    Watch the videos and complete the check your understanding questions before moving on to the module assignments. Practice problems are not graded but should be completed to facilitate your learning. 

     

     


    1. State that work is done when a force moves an object in the direction of the force.
    2. Calculate work done, using the equation W= Fx d, and state the unit as the joule(J).
    3. Define energy as the ability to do work.
    4. State examples of energy in different forms and their conversion.
    5. Describe the energy of motion (kinetic) and energy of position relative to ground (gravitational potential).
    6. State the law of energy conservation as; energy is neither created nor destroyed.
    7. State some renewable sources of energy (biomass, solar, wind, waves, water).
    8. Describe production of thermal energy by burning fuels.
    9. Investigate and describe qualitatively the thermal expansion of solids, liquids and gases.
    10. Describe the structure and operation of a liquid in glass thermometer (features of a clinical thermometer not required.)
    11. List some everyday applications and consequences of thermal expansion.
    12. Describe the application of thermal expansion in thermometers.

        There are no required readings.

      1. In this module we will learn about transportation. 


        Be sure to complete the short answer assignment, the lab, the Mastery Exercises, and the module exam. Watch the videos and complete the practice problems to facilitate your learning. 

        Short Answer Assignment responses should be at least 200-300 words and referenced. Refer to the Required/Recommended reading materials or provide an additional reference to an article of your choice.

        1. Describe the composition of blood (plasma, red blood cells, white blood cells and platelets).
        2. State the functions of the red blood cells (transport of oxygen), white blood cells (defense), plasma (transport of dissolved food, heat and waste material).
        3. Label parts of the internal structure of the human heart (right and left atria, right and left ventricles, valves (specific names not required) aorta, pulmonary vein, pulmonary artery and vena cava) and state their functions.
        4. Describe the direction of flow of blood through the heart.
        5. State the functions of three types of blood vessels (arteries, veins and capillaries).

        There are no required readings.
