absorb
to soak in; as in water into a sponge, lotion into the skin, etc.
uneven heating
the situation in which soil and water gain and lose energy differently
experiment
an investigation designed to find out how variables affect outcomes
expand
to increase in size or volume; when inhaling the lungs will do this
radiant transfer
the movement of the Sun's energy to other objects around it (as in to Earth)
reradiation
the process by which the Sun's radiation is absorbed by earth materials and then transferred again to other areas
convection current
a circular movement of fluid (such as air) that is a result of uneven heating of the fluid
earth material
solid substances that are on Earth's surface: rocks, soil, sand, etc.
less dense
when matter has less mass per volume than other matter
solar collector
any object or material placed in the Sun to absorb energy for eventual transfer to water or air
ray
any beam of narrow light emitted from the Sun
solar water heater
rooftop containers designed to allow the Sun's energy to heat the water inside instead of conventional electricity
variable
anything that you can change that might affect the outcome of an experiment or investigation
radiation
energy that travels through air and space (sometimes created in laboratories) #1
radiant energy
energy that travels through air and space (usually from the Sun)
more dense
when matter has more mass per volume than other matter
energy transfer
the movement of energy from one place to another; we experimented with this during our collisions
conduction
the transfer of energy from one place to another BY CONTACT
reflect
to bounce off an object or surface
solar energy
energy that is emitted from the Sun
contract
to become drawn together; become smaller; to shrink
fluid
a substance (liquid or gas) that is capable of flowing and that changes its shape when acted upon by a force
solar energy exposure
the amount of solar energy that an object or surface is given; laundry being put out into the Sun dries faster due to this effect
