The Law of Conservation of energy says that energy can neither be _______ or ________.
created
destroyed
True or False: An energy chain shows how energy changes forms?
True
True or False: Fossil fuels are examples of renewable sources of energy?
False
True or false: The wind and sun are examples of nonrenewable sources of energy?
False
True or False: Temperature is the measure of how much heat an object has?
True
Multiple Choice: The measure of how much heat an object has is called?
A. Energy
B. Temperature
C. Atoms
Temperature
True or false: Wind energy was first developed before the birth of Christ?
True. Wind energy was first developed with windmills in 200 BC in Persia and China.
True or false: Hydropower (water) is one of the oldest power sources on the planet?
True. Hydropower is one of the oldest power sources on the planet.
True or False: The world's largest hydroelectric (water energy) facility in the world is in the United States?
False. Three Gorges Dam, China, is the world’s largest hydroelectric facility.
Vocabulary - We use these to trap sunlight energy and transform it into usable energy, such as heating water, buildings, pools, etc.
Solar panels
True or false: Energy from the ocean is generated by harnessing the movement of waves, currents, and tides.
True. Energy from the ocean is generated by harnessing the movement of waves, currents, and tides. Devices such as buoys and turbines are used to convert this movement into energy. Certain components of these devices move with the water, producing electricity.
Name 3 types of renewable sources of energy.
Solar Energy: The sun's rays can be captured and converted into electricity using solar panels and photovoltaic cells.
Vocabulary: This type of energy or power is the primary source of energy used by plants, animals, and humans?
Solar Power
Vocabulary: This type of nuclear energy is when the center of a big atom, like uranium, splits into smaller atoms, releasing a lot of energy as heat and other particles.
Nuclear Fission
Vocabulary: This type of nuclear energy is when tiny bits of matter, like atoms, join together to make a brand new, bigger thing.
Nuclear Fusion
The most famous example is in the sun and stars, where tiny hydrogen atoms smash together in the intense heat to become a helium atom. This process creates a lot of energy, which is what makes the stars shine so brightly.
Vocabulary: This reaction keeps going by itself, like dominoes falling, after one splits and hits others.
Chain Reaction
Vocabulary: The transfer of heat through indirect contact is called __________.
Radiation
Vocabulary: The transfer of heat through direct contacts is called ________________.
Conduction
Vocabulary: The transfer of heat through direct contact is called __________.
Convection
