The sun causes a water puddle to evaporate. This is an example of:
convection
conduction
radiation
all of these
If all of these objects were dropped from the same height, which one would have the most kinetic energy?
ping pong ball
baseball
glass marble
bowling ball
Heat always moves...
...through gas or solid objects.
...from objects with higher temperatures to objects with lower temperatures.
...from an object into the air that surrounds it.
...from objects with conduction to objects with convection.
Which of these is true?
Potential energy increases when speed increases.
An object sitting on a shelf has no potential energy.
Kinetic energy is higher if the mass of a moving object is higher.
Kinetic energy only changes when speed changes.
Which of these would make a good claim sentence in a CER?
Deep water is colder because of convection.
I think deep water is colder because of convection.
Convection means that colder water sinks and warmer water rises to the top.
This proves that convection is important to water temperature.
You want to do an experiment to test which color blocks heat transfer better. For your test, you should choose different objects that...
...are poor conductors of heat, like wood for example.
...are the same size, but with different masses.
...can be heated without melting.
...are the same in every way except the color.
What type of heat transfer can happen through empty space?
convection
conduction
radiation
all of these
Which one of these is the equation for kinetic energy? The m is mass, and s is speed.
31⋅m⋅s3
ms⋅s⋅m2
21⋅m⋅s
21⋅m⋅s2
A car speeds up for three seconds, and its kinetic energy (K) changes. Which one of these graphs shows that situation?
A
B
C
D
What type of heat transfer happens within a solid object?
convection
conduction
radiation
all of these
Which of these sentences could be part of the evidence section of a CER?
Hot air balloons rise because of convection.
My teacher explained that hot air rises and cool air sinks.
There are many reasons why convection is important to hot air balloons, and I will share them with you now.
This proves that convection causes them to rise.
What is a Joule?
the amount of kinetic energy something has
the mass of an object
a unit for measuring energy
the equation for kinetic energy
What are the states of matter? Select all that apply!
liquid
mass
gas
solid
kinetic
Hot blobs of wax in a lava lamp rise to the top of the liquid. This is an example of:
convection
conduction
radiation
all of these
If you add up the energy of all the tiny particles that make up an object, you will find its...
...thermal energy.
...mass.
...state of matter.
...conduction.
When an object is held up higher from the ground, what does it gain more of?
thermal energy
mass
kinetic energy
potential energy
Which one of these is the Law of Conservation of Energy?
When the mass increases, the kinetic energy increases.
Heat can be transferred by convection, conduction, or radiation.
Energy is never created or destroyed; it only changes form.
Heat always moves from high temperatures to low temperatures.
What type of heat transfer comes from hot gas or liquid rising and cool gas or liquid sinking?
convection
conduction
radiation
all of these
Which one of these sentences could part of the reasoning section of a CER?
I learned in class that an object with higher speed has more kinetic energy.
When we measured it, we found that the mass of the second object was 450 grams.
Since the mass and speed of the second object were higher, I know its kinetic energy was higher.
The kinetic energy was higher in the second object.
An ice cube starts to melt in your hand. This is an example of:
convection
conduction
radiation
all of these
