Exploring historical impact of drought on civilizations
Engineering a way to retain water

Water is our lifeline that bathes us and feeds us. In ancient cultures
water represented the very essence of life. The Romans were the first to
pipe water into their growing cities, especially with their aqueducts.
The movement of water is controlled by gravity and any obstruction
that can affect the flow. They
also realized that sewage water could cause damage to their people,
and needed to be removed from large areas of people.
played a role not only in the history of countries, but in religion,
mythology, and art. Water in many religions cleanses the soul through holy
water. For example, the water at Lourdes, France is thought by many
religions to be sacred water with healing powers. In Egyptian mythology,
the Nu was the beginning of everything and represented water. It brought
life to their people, but in drought, produced chaos.
have engineered ways in which they can store water.
They would build levee or dams to control the flow of water.
Levee’s can prevent floating which dams are built to save water
from flowing away to be used when there is no water.
Civilizations have used wells to store water.
has always been perceived as a gift from the gods as it rained from the
Mr. Drippy to review the water cycle.
Notice the term infiltration.
Water can move into the ground through porous rocks.
over the main principle of water movement on the surface of the earth.
Students use “Shape It” clay to
mold how water can flow downhill.
They need to create a path for the water to flow down controlled by
gravity. Use a marble to see
if their structure actually works.
If not have students mold rivers and creeks until the marble flows
to the bottom.
they use gravity to make a watershed where the water flows easily,
challenge the students to create areas where you can trap water.
For example a dam will allow water to pool, but then you can create
an artificial lake if the water can flow back.
Please note the bottom on the “lake” would need a low or flow rate,
so the water is not lost to the ground.
Roll the marble and see if it works.
It will probably take several designs to get it work correctly.
