Repetition vs. Replication
Scientific knowledge can be confirmed or evaluated by being _____________.
Repeated. (Repetition or Replication)
A MEASUREMENT of the AVERAGE kinetic energy of a substances particles.
What is Temperature?
Energy that is transferred from warm objects to cooler objects.
What is heat or thermal energy?
The chemical bonds in sugar
chemical energy
State the law of conservation of energy.
Energy can not be created nor destroyed. It can only be transformed into other forms of energy
when a scientist copies another scientists investigation
What is Replication?
The TOTAL kinetic energy of the particles of a substance.
What is thermal energy?
Heat transfer that occurs between objects in direct contact.
What is conduction?
A bird resting on its nest in a tree.
potential energy
Describe the energy transformation that happens as a fan works.
Electrical to mechanical/kinetic.
when one scientists repeats the same investigation (trials)
What is Repetition?
The particles move faster.
The transfer of energy as electromagnetic waves.
What is radiation?
A baseball thrown to second base
kinetic energy
Describe the energy transformation occurring as a car travels down a hill
potential energy is transformed into kinetic energy.
Jim goes to the park each day for a week to count the number of birds in the pond.
What is repetition?
Which has more thermal energy? A cup of boiling water or an iceberg.
What is the iceberg? It has more particles.
The transfer of energy due to the rising and sinking of matter due to density differences.
What is Convection?
Radiant energy
Describe the energy transformation that happens as a wind turbine generates electricity.
Kinetic to mechanical to electrical energy.
Tammy gets Jim procedure and goes to the park today to count the birds in the pond.
What is replication?
Why does temperature stay the same during a phase change?
The extra energy is being used to make or break bonds.
How are radiation and conduction different?
What is Radiation doesn't require contact.
listening to music
Sound energy /Kinetic Energy (Sound is vibrations ).
How energy transformations support the law of conservation of energy?
Energy transformations show that energy changes to other forms. It is not being created or destroyed.
