TEKS Lessons
Matter and Energy
7.5A Recognize
that
radiant energy
from the Sun is transformed into chemical energy
through the process of photosynthesis
4.3 Energy
Transformation
through
Photosynthesis
7.5B Demonstrate and explain the cycling of matter within
living systems such
as in the
decay
of biomass in a compost bin
2.7 Cycling of Matter
7.5C Diagram the flow of energy
through living systems, including
food chains, food webs,
and energy pyramids
2.5 Flow
of Energy
Matter and Energy
7.6A Identify
that organic compounds contain carbon and other elements such as
hydrogen, oxygen, phosphorus, nitrogen, or
sulfur
5.2 Breakdown
of Organic
Molecules
7.6B Distinguish
between
physical and chemical
changes in
matter in the digestive
system
5.1 Physical
and Chemical
Changes in
Digestion
7.6C Recognize
how large molecules are broken down into smaller molecules such as
carbohydrates can be broken
down into sugars
5.2 Breakdown
of Organic
Molecules
Force, Motion, and Energy
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
5.4 Work/Skeletal and Muscular
Systems
7.7B Illustrate the transformation of
energy within an organism such as the transfer from
chemical energy
to heat and thermal energy in digestion
5.2 Breakdown
of Organic
Molecules
7.7C Demonstrate and illustrate forces that affect motion in
everyday
life such
as
emergence
of seedlings, turgor pressure, and geotropism
4.3 Energy
Transformation through
Photosynthesis
3.4 Ecological
Succession
