Analyze data and rebuild and retest prototype as necessary. </li></ul></ul>
    9. 14. Scientific Method
    10. 15. Steps in the Scientific Method <ul><li>Observation </li></ul><ul><li>Hypothesis </li></ul><ul><li>Experiment </li></ul><ul><li>Data Collection </li></ul><ul><li>Conclusion </li></ul><ul><li>Retest </li></ul>
    11. 16. Observations <ul><li>Gathered through your senses </li></ul><ul><li>A scientist notices something in their natural world </li></ul>
    12. 17. Observations <ul><li>An example of an observation might be noticing that many salamanders near a pond have curved, not straight, tails </li></ul>
    13. 18. Hypothesis <ul><li>A suggested solution to the problem. </li></ul><ul><li>Must be testable </li></ul><ul><li>Sometimes written as If…Then… statements </li></ul><ul><li>Predicts an outcome </li></ul>
    14. 19. Hypothesis <ul><li>An example of a hypothesis might be that the salamanders have curved tails due to a pollutant in the moist soil where they live. </li></ul>
    15. 20. Experiment <ul><li>A procedure to test the hypothesis. </li></ul>
    16. 21. Experiment <ul><li>Variable – factor in the experiment that is being tested </li></ul>
    17. 22. Experiment <ul><li>A good or “valid” experiment will only have ONE variable! </li></ul>
    18. 23. Controls and Variables
    19. 24. Scientific Experiments Follow Rules <ul><li>An experimenter changes one factor and observes or measures what happens. </li></ul>
    20. 25. The Control Variable <ul><li>The experimenter makes a special effort to keep other factors constant so that they will not effect the outcome. </li></ul><ul><li>Those factors are called control variables. </li></ul>
    21. 26. What is the Purpose of a Control? <ul><li>Controls are NOT being tested </li></ul><ul><li>Controls are used for COMPARISON </li></ul>
    22. 27. Other Variables <ul><li>The factor that is changed is known as the independent variable . </li></ul><ul><li>The factor that is measured or observed is called the dependent variable . </li></ul>
    23. 28. Example of Controls & Variables <ul><li>For example , suppose you want to figure out the fastest route to walk home from school. </li></ul><ul><li>You will try several different routes and time how long it takes you to get home by each one. </li></ul><ul><li>Since you are only interested in finding a route that is fastest for you, you will do the walking yourself. </li></ul>
    24. 29. What are the Variables in Your Experiment? <ul><li>Varying the route is the independent variable </li></ul><ul><li>The time it takes is the dependent variable </li></ul><ul><li>Keeping the same walker throughout makes the walker a control variable. </li></ul>
    25. 30. One more thing… it is best to make several trials with each independent variable.
    26. 31. Valid Experiments
    27. 32. Remember: To be a Valid Experiment: <ul><li>Two groups are required --- the control & experimental groups </li></ul><ul><li>There should be only one variable </li></ul>
    28. 33. Data <ul><li>Results of the experiment </li></ul><ul><li>May be quantitative (numbers) or qualitative </li></ul>
    29. 34. Data <ul><li>Must be organized </li></ul><ul><li>Can be organized into charts, tables, or graphs </li></ul>
    30. 35. Conclusion <ul><li>The answer to the hypothesis based on the data obtained from the experiment </li></ul>
    31. 36. Retest <ul><li>In order to verify the results , experiments must be retested. </li></ul>

    70. 111. Renewable and Nonrenewable Sources Renewable Nonrenewable Main Menu
    71. 112. Types of Energy Kinetic Energy Potential Energy Main Menu
    72. 113. Forms of Energy Radiant Electrical Chemical Thermal Nuclear Magnetic Sound Mechanical Main Menu
    73. 114. Radiant Energy Radiant energy is also called electromagnetic energy. Radiant energy is the movement of photons. All life on earth is dependent on radiant energy from the sun. Examples of radiant energy include radio waves (AM, FM, TV), microwaves, X-rays, and plant growth. Active solar energy uses photovoltaic panels and light to turn radiant energy into chemical energy. Forms of Energy
    74. 115. Chemical Energy Chemical energy is the energy stored in the bonds of atoms and molecules. This a form of potential energy until the bonds are broken. Fossil fuels and biomass store chemical energy. Products that contain chemical energy include: TNT, baking soda, and a match. Biomass, petroleum, natural gas, propane and coal are examples of stored chemical energy. Forms of Energy
    75. 116. Electrical Energy Electrical energy is the movement of elections. Lightning and static electricity are examples of electrical energy that occur naturally. Science hasn't found a way to use natural forms of electrical energy, like lightning. Instead, we use different energy sources to create electrical energy by using generators and turbines. Forms of Energy
    76. 117. Nuclear Energy Nuclear energy is the energy stored in the nucleus of an atom. Nuclear energy is unusual in that it can give off energy in the form of light or heat, but it is the change in the atom's makeup that produces the energy. Submarines, power plants, and smoke detectors all use nuclear energy. Nuclear power plants use uranium, a radioactive element, to create electricity. Forms of Energy
    77. 118. Thermal Energy Thermal energy is the internal energy in substances-the vibration and movement of atoms and molecules within substance. Thermal energy is created in the movement of atoms. Boiling water, burning wood, and rubbing your hands together really fast are all examples of heat energy. Geothermal and passive solar are sources of heat energy, but biomass (a type of chemical energy) can be burned to produce heat energy. Forms of Energy
    78. 119. Sound Energy Sound energy is the movement molecules in the air that produces vibrations. Alarms, music, speech, ultrasound medical equipment all use sound energy. VCR tapes change sound energy into electrical energy. The electrical energy records the sound using magnetic tape. Speakers read the magnetic tape and change it back into sound. Forms of Energy
    79. 120. Mechanical Energy Mechanical energy is the movement of machine parts. Mechanical energy is also the total amount of kinetic and potential energy in a system. Wind-up toys, grandfather clocks, and pogo sticks are examples of mechanical energy. Wind power uses mechanical energy to help create electricity. Potential energy + Kinetic energy = Mechanical energy Next
    80. 121. Mechanical Energy Potential energy + Kinetic energy = Mechanical energy Forms of Energy Example of energy changes in a swing or pendulum.
    81. 122. Magnetic Energy Magnetic energy is the attraction of objects made of iron. Medical equipment, compass, refrigerator magnets are all examples of magnetic energy. Any type of energy source that uses a generator in the process to make electricity uses magnetic energy. Forms of Energy
    82. 123. Kinetic Energy Kinetic energy exists whenever an object which has mass is in motion with some velocity. Everything you see moving about has kinetic energy.  The kinetic energy of an object in this case is given by the relation: KE = (1/2)mv 2 m=mass of the object V=velocity of the object The greater the mass or velocity of a moving object, the more kinetic energy it has. Kinetic Energy Lab Next
    83. 124. Kinetic Energy The greater the mass or velocity of a moving object, the more kinetic energy it has. Kinetic Energy Lab Types of Energy
    84. 125. Potential Energy Potential energy exists whenever an object which has mass has a position within a force field. The most everyday example of this is the position of objects in the earth's gravitational field. The potential energy of an object in this case is given by the relation: PE = mgh   PE = Energy (in Joules) m = mass (in kilograms) g = gravitational acceleration of the earth (9.8 m/sec2) h = height above earth's surface (in meters) Potential Energy Lab Types of Energy
    85. 126. Law of Conservation of Energy Law of Conservation of Energy- Energy can neither be created nor destroyed. Energy is always changing from one kind to another. The total energy of an object never changes. Potential energy + Kinetic energy = Total energy and Total energy – Kinetic energy = Potential energy and Total energy - Potential energy = Kinetic energy Main Menu Main Menu
    86. 127. Work Main Menu Next Work is the transfer of energy through motion. In order for work to take place, a force must be exerted through a distance. The amount of work done depends on two things: the amount of force exerted and the distance over which the force is applied. There are two factors to keep in mind when deciding when work is being done: something has to move and the motion must be in the direction of the applied force. Work can be calculated by using the following formula: Work=force x distance
    87. 128. Work Main Menu Main Menu Work is done on the books when they are being lifted, but no work is done on them when they are being held or carried horizontally.
    88. 129.
