1
Students conduct an
investigation at Malibu
Lagoon State Park.
California
Standard
Students conduct a meaningful
investigation.
The periodic table displays the
elements in increasing atomic
number and shows how
periodicity of the physical and
chemical properties of the
elements relates to atomic
structure.
The periodic table displays the

Students know how to use the
pH scale to characterize acid
and base solutions.

Warm-up
MB-20 Questions object
MB-Would a steel ball (20c) travel
faster through water at 25c or -5c or
would it travel at the same speed
through each?
MB-A fishing boat is lying in the
harbor. There is a rope ladder
hanging over the side with its end
touching the water. The rungs of the
ladder are 1 meter apart and the tide
is rising at 50 centimeters an hour
∙MB-Kerry Novel was a professional
writer. He was writing one day during
a terrible lightning storm when
suddenly he died. How did he die?
MB-There are 3 Light bulbs in one
room, three switches in the other room.
You can only go into the room with
the light bulbs once to check. How do
you find out which switch goes with
which lightbulb?
TOTD-4400 Children die daily
from unsafe and unsanitary water.
TOTD-“All the ants on the planet
taken together have a biomass
greater than that of humans. Ants
have been incredibly industrious for
millions of years, yet their
productiveness nourishes plants
animals and soil. Human industry
has been in full swing for little over
a century, yet it has brought about a
decline in almost every ecosystem
on the planet. Nature doesn’t have
a design problem, people do.”Cradle to Cradle
Agenda
(APK-First)
(EPK)
∙Review Field Trip Worksheet
∙Field trip feedback-next trip
∙Send Pictures
∙Photorelease!!!
∙Work time for lab report
from Malibu investigations
(due Thursday-bring one
paper copy for your group and
post your conclusion on
nicenet-everyone)
∙Pass out periodic tables
∙Color metals, non-metals,
metalloids
∙Periodic Table-Focus on
seawater elements
∙Find protons, neutrons,
electrons, valence electrons
∙Make element flashcards
∙How is the periodic table
organized?
At the end of 6 hours, how many of
the rungs will be covered if there
are 10 rungs?
Students summarize the
importance of stable pH to the
world’s oceans.
TOTD-Spanish is the second most
commonly spoken language in the
world.

Review
TOTD-Can you name the top 5
websites in terms of visitation?
TOTD- “The planet's population
continues to explode: from 1 billion
in 1820, to 2 billion in 1930, 3
billion in 1960, 4 billion in 1974, 5
billion in 1988, and 6 billion in
2000.” Source: CIA Factbook
∙Review periodic table
∙Introduction to sea water
chemistry- salinity p 174-177
∙Read as a class
∙Answer review questions
related to salinity
∙Salinity test demonstration
(hypothesis)-venice beach water
vs river water.
∙Where did the salt come from?
∙Present investigations
∙Make list for notebook/binder
check
∙Introduce Oceanography So
Far..project-This could be a
poster, PowerPoint, paper,
concept map, image map,
brochure, book, or other
innovative project that shows
your knowledge of
oceanography so far.
