• RED SLIDE: These are notes that are very
important and should be recorded in your
science journal.

-Nice neat notes that are legible and use indentations
when appropriate.
-Example of indent.
-Skip a line between topics
-Don’t skip pages
-Make visuals clear and well drawn.

• RED SLIDE: These are notes that are very
important and should be recorded in your
science journal.
• BLACK SLIDE: Pay attention, follow
directions, complete projects as described
and answer required questions neatly.

Demonstration
-Where’s the water?
- Teacher fills 5 gallon bucket which represents
all of the water on earth.

• The bucket represents

–Salt Lakes
–Rivers
–Ice Caps / Glaciers
–Atmosphere
–Groundwater
–Freshwater Lakes
–Potable Water (Useable water available for
humans after pollution and contamination)

• Answer! Humans cannot drink saltwater and
survive.

• Answer! Humans cannot drink saltwater and
survive.
– Saltwater dehydrates you faster than no water at
all. It also kills plants and contaminates the soil.

• Which of the plants in this study was given
the most saltwater?

• Parts of Somalia are controlled by
warlords with militias.

• Many places in the world are burdened by
civil war and fighting.

• Activity! Reading the article about the war
over the well in Somalia.

Gathered from a dirty watering
hole ½ hours walk

Bowl is also used to collect goats
urine for washing kitchen tools

• Indoor plumbing is very rare.
– Most people in this world must carry water to
their dwelling.

• Activity! (Optional) Class must carry several
5 gallon buckets filled with water outside
simulating a walk from the well to home.
– Do not carry on your head / bearing the weight
on your neck.
– Those young girls and boys have been doing it
since they could walk and have built-up
strength. (Your neck will break!)

• Question: How would your water use
change if you had to collect and carry every
drop?

• Video Link! Drought and Famine in Africa.
– Observe how people in the video rely on water.

• Activity! Guess the picture beneath the
boxes. Please raise your hand when you
think you know it.
– You only get one guess.
