Step 1 ~Measure out 50 milliliters of water into a beaker A from
the water container.
Step 2 ~ Grab a funnel and put a single coffee filter in it. After
this fill the funnel with sand up until the marked line that you
will find on your funnel.
Step 3 ~ Place the funnel with the filter paper and sand on top of
beaker B.
Step 4 ~ Pour the 50 milliliters of water from beaker A into the
funnel and watch it drip down into beaker B. Make sure that you
do not fill the funnel too high with water, make sure the water
level does not go above the sand.
Step 5~ After beaker A has been emptied, wait for the water to
finish filtering through the sand ( about 30 seconds). After this
measure the amount of water that is in beaker B by looking at it
while level with the water level.
Sand
Step 6~ Compare that amount of water that is in beaker B to
the amount that you started with in beaker A (50 milliliters).
Also note the color change in the water from beaker A to beaker
B’s color. Did the color change?

The End
Infiltration is the downward
movement of water through
the soil.

Water Table is were the water
is underground.
Groundwater flow is the
direction the water moves
underground.
Evaporation is when water
becomes a gas and rises
into the atmosphere.

Precipitation is when some
form of water falls to the
ground under gravity.
Examples of precipitation
are snow, rain, hail, and
freezing rain.
A well is an opening in the
ground. This hole goes
down deep enough until it
hits the water table. Water
then can be pumped up
from the water down at the
bottom of the well ( or
pulled up with a bucket
and some rope).
A cone of depression is
the dip in the water level
of the aquifer in the spot
where the well is dug.
Porosity~ Amount of empty
space between objects.
Low Porosity~ When small
rocks are very close together.
There is little space between
the rocks for water.
High Porosity~ When larger
rocks are together they
create large gaps in between
the rocks. This allows water
to go through quickly.
This is an area of rocks
which water cannot, or has a
hard time, passing through.
It has low Porosity.
This is an area of rock that
water travels through very
easily. It has high porosity.
Acid Rain is a mixture of
gases and water that
contain a high amount of
acid which causes the
rain to have a lower pH
than normal. Normal
rain has a pH around 5.6
acid rain has a pH
around 4.3.
Runoff occurs when the ground
can no longer take in more
water. The excess water s flows
on top of the ground toward
oceans in the form of steams,
rivers , and lakes.
Plants take up water from the
ground and they thing in that
water goes into the plants.
Thing such as oil and pesticides
can end up in the plants.

Household pesticides
include insect killer,
fertilizer, and weed killers.
They get into the ground
water and make it unsafe
to drink.
Farm pesticides are powerful
chemicals sprayed on crops to
kill weeds and bugs. It is usually
done with an airplane.
It was disposed of at the
bottom of the ocean and last
thousands of years.
It is chemicals like lead,
mercury, and acid that are
dumped into the water. They
can be harmful to humans and
other forms of life.
Products such as bleach and
soaps that are poured down the
drain. They can be poisonous if
not purified.
Can come from cars, ships, oil
refineries and gas stations. Oil
is extremely toxic and hard to
dispose of.
