Welcome to the 10th
grade WASL.
Although the State of Washington will not require passage of the
10th grade WASL to graduate until 2008, this school district
requires it now!
This is the 10th
grade science WASL. You will need to answer the following
actual questions correctly in order to pass. Once you pass
all portions of the WASL,
you can graduate.
REMEMBER to note
the code found in the cache - you will need it in order to
graduate.
Note: There has been frequent bear activity reported in
the vicinity of this cache (see various logs). I believe the area
is safe, but if you attempt this cache, please make sure you brush
up on your bear-encounter etiquette before going, and remember that
cache seekers assume all risks.
Super Grow Fertilizer
For their
science project, Elena and Glen decided to test the effectiveness
of a new fertilizer, Super Grow. The manufacturer of the fertilizer
claims Super Grow contains ammonium nitrate
(NH4N03) and will shorten the amount of time
required to produce mature, pod-bearing plants from seeds. The
manufacturer claims the plants treated with Super Grow will be
mature in half the normal time and is environmentally
safe.
Elena and Glen
choose to test Super Grow on pea seeds. They performed the
following investigation.
Question:
How will Super
Grow affect the germination of pea seeds and the growth of pea
plants?
Hypothesis:
More pea seeds will germinate and
the pea plants will grow faster with Super Grow because the seeds
and plants will have extra nutrients.
Materials:
Procedure:
-
Put equal amounts
of soil mix in containers #1 and #2.
-
Add Super Grow fertilizer
to the soil mix in container #2 in a concentration recommended by
the manufacturer.
-
Plant 15 pea seeds in
each container.
-
Water each container
equally every day.
-
Be sure each container
gets the same amount of light and stays at a temperature of
20°C.
-
Record the number of pea
seeds that germinate.
-
Record the time (number
of days) for the pea plants to mature.

1 Is the
investigation a fair test of their question?
-
No, the investigation used only pea
seeds.
-
Yes, because the data support the
hypothesis.
-
Yes, the investigation included an
experimental control condition.
-
No, because the same number of
seedlings did not grow to mature, pod-bearing plants.
2 In the investigation,
more seed germinated in the container not treated with Super
Grow. Does this mean that Super Grow is bad for plants?
-
Yes, because one less seed
germinated.
-
No, because a small experimental
error is expected.
-
No, because Super Grow was tested by
the manufacturer.
-
Yes, because all of the seeds in
Super Grow did not germinate.
3 In the
investigation, which variable was manipulated (changed)?
-
Temperature of the room
-
Time for plants to mature
-
Number of
pea seeds used
-
Presence of Super
Grow
