SCIENCE PROCESS SKILS

1. Observation- Noting the properties of
objects and situations using the five sense:
Seeing, Hearing, Touching, Smelling, Tasting
2. Classifying- Relating objects and events
according to their attributes which may
involve classifying: Places, Objects, Ideas,
Events
3. Measuring- Expressing the amount of an
object in quantitative terms, or comparing
an object to a standard: Length in Meters,
Volume in Liters, Mass in Grams, Force in
Newtons, Temperature in Degrees Celsius
4. Communicating- Process of describing,
recording, and reporting experimental
procedures and results to others:
Oral, written, or mathematical, Organizes
ideas using appropriate vocabulary, graphs,
other
visual
representations,
and
mathematical equations.
5. Inferring- Giving an explanation for a
particular object or event
6. Predicting- Forecasting a future occurrence
based on past observations or the extension
of data
7. Interpreting- Arriving at explanations,
inferences, or hypotheses from data that has
been placed in a data table or graph
8. Experimenting- Testing a hypothesis
through the manipulation and control of
independent variables and noting the effects
on a dependent variable

The highest mountain and volcano in the
Solar System is on the planet Mars. It is
called Olympus Mons which is three times
higher than Mt. Everest.
Alfred Wegener proposed the Continental
Drift Theory
Sliding Process describes the process of
subduction
The scientists discover that rocks farther
away from the mid-ocean ridge were older
than those near it by determining the age of
rock samples obtained by drilling on the sea
floor
When a continental plate collides with an
oceanic plate, the oceanic plate sinks into
the mantle
Iceland is an example of Divergent
Boundary

Accoording to plate tectonics, lithosphere is
made up of plates
The objection that critiques Wegener’s idea
is that the continents that were capable of
moving was physically impossible
The
following
observations
are
instrumental in formulating the hypothesis
of seafloor spreading:
1. The depth of the ocean
2. Magnetization of the oceanic crust
3. Thickness of seafloor spreading
NOT the result of tsunami is the mortality
rate increase in the next 5 years
The Earth has a constant surface area, thus,
when new land is created at the ridge
between plates, the same amount of land
created must be absorbed into the earth at
subduction zone
Convection current in the mantle is the
driving forces that facilitate the movement
of the lithospheric plates
The following increases with the distance
from a mid-ocean ridge
1. The depth to the sea floor
2. The age of oceanic lithosphere
3. The thickness of the lithosphere
Through the continuous movement of the
lithospheric plates over the asthenosphere,
one can infer that the islands of the
Philippines will become scattered all over
the world.
The oceanic crust is pushed from the ridge
that’s why oceanic crust sink beneath the
continental crust
Mountain ranges are formed when plates
collide and fold under enormous pressure
How to locate the epicentre of a recent
earthquake:
1. Obtain data from three different
seismological stations
2. Determine the difference in the arrival
time of S and P waves recorded from
each of the seismological stations
3. Determine the distance of the epicentre
from the station
4. Use the triangulation method to locate
the center
This is the correct sequence of the different
arrivals
FIRST- P Waves
SECOND- S Waves
LAST- Surface Waves
You can determine the location of the
epicentre by having a data showing the

arrival time of the P and S waves recorded
from three stations
If S wave was to go from solid to a liquid, its
velocity will decrease
