Guiding Questions
- Who is
responsible for
safety in the
laboratory and
during field
investigations?
-How essential is
following safety
rules & procedures
to all laboratory &
field experiences
that are
specifically
outlined in the
Texas Safety
Standards?
- How do safety
practices before,
during, & after
laboratory &
field investigations
reduce the
likelihood of
incidents?

Sample
Assessment
A scientist spilled a
few drops of dilute
hydrochloric acid
(HCl) on a lab table.
For safety purposes,
the scientist sprinkled
some baking soda
(NaHCO3) onto the
spill. Which
observation would
provide the best
evidence that a
chemical reaction
occurred?
F The baking soda
and hydrochloric acid
combined, and
bubbles formed.
G The baking soda
absorbed the
hydrochloric acid.
H Some of the
baking soda
dissolved in the
hydrochloric acid.
J The hydrochloric
acid evaporated,
leaving only the
baking soda.

Work
7.7a-- contrast situations
where work is done with
different amounts of force to
situations where no work is
done such as moving a box
with a ramp and without a
ramp, or standing still
(Supporting Standard)
Guiding
Questions/
Specificity
Guided Question:
-What happens when
work is done with
different amounts of
force?
-How does work change
when using simple
machines?
-How would you define
work?
-How can work be
measured?
-How do simple machines
make work easier?
Teacher Note:
- Students come from 6th
grade with a basic
understanding of
potential/kinetic energy,
inclined planes and
pulleys (6.8A,E)
- This SE emphasizes that
students should contrast
situations with different
amounts of force (change
in energy) rather than a
calculation using the
formula for work.

7.5.a – recognize that radiant
energy from the sun is
transformed into chemical
energy through the process of
photosynthesis
Guiding
Questions/
Specificity
Guided Questions
- Identify that
radiant energy is
from the sun.
- How is radiant
energy transformed
into chemical
energy during
photosynthesis?
- What is the
equation of
photosynthesis?
Specificity:
Make sure students
understand the flow
and transformation
of energy.
A plant needs H2O,
CO2, and light from
the sun to make
glucose as food and
produce oxygen.

Photosynthesis
Plants undergo
photosynthesis, which
helps them grow. How
does sunlight affect the
process of
photosynthesis?
A. It encourages rain,
which provides the
water needed for
growth.
B. It warms the leaves
of plants, which allows
the reaction to occur
quickly.
C. It provides solar
energy, which plants
use to drive the
reaction.
D. It increases the air
temperature, which
creates energy.

organisms respond to external
stimuli found in the
environment such as
phototropism and fight or
flight
Revised Spring 2014
Teacher Notes:
Turgor pressure
prevents plants from
wilting which results in
increased light
exposure for
photosynthesis. This
topic will be revisited
during the 5th six weeks
with plant cells and
vacuoles.
- It is recommended
that students plant
seeds to observe the
emergence of seedlings,
turgor pressure, and
geotropism
