If someone wants to conserve natural resources, which of these will they do

• Carpool
• Recycle
• Ride their bike to school
• Turn off lights when they leave a room

What is an advantage to solar energy

• it pollutes
• it is gathered 24 hours a day
• it works well no matter where you are in the world
• it is renewable

If a man is pushing a wheelbarrow up a hill, describe what is occurring in terms of energy when the man is half way up the hill. 

• Decreasing Potential, Increasing Kinetic
• Increasing Potential, Decreasing Kinetic
• Increasing potential and kinetic stays about the same
• Both potential and kinetic decreasing
