TEKS Lessons
Organisms and Environments
7.10A Observe and describe how
different environments, including microhabitats
in
schoolyards and
biomes, support different varieties of organisms
2.3
Schoolyard Microhabitat
2.4
Environments and Organisms
7.10B Describe how biodiversity
contributes to the
sustainability of an ecosystem 2.6 Biodiversity
7.10C Observe, record, and describe the role of ecological
succession such
as in
a
microhabitat of
a garden with weeds
3.4
Ecological Succession
Organisms and Environments
7.11A Examine organisms or their structures such as insects or leaves and use
dichotomous keys
for identification
2.2
Dichotomous Key
7.11B Explain variation within
a population
or species by
comparing
external features,
behaviors, or physiology of organisms that enhance their survival such as
migration,
hibernation, or storage of food
in a bulb
2.8
Variations within Populations
7.11C Identify
some changes in
genetic traits that have occurred over several generations
through natural
selection and selective breeding such
as the
Galapagos Medium
Ground Finch (Geospiza
fortis) or domestic animals
2.9
Natural Selection
4.8
Selective Breeding
Organisms and Environments
7.12A Investigate and
explain how
internal structures
of organisms have adaptations that
allow
specific functions such as gills in
fish, hollow
bones in
birds, or xylem in plants
4.3 Energy
Transformation
through
Photosynthesis
5.7
Internal Structures
7.12B Identify
the main
functions of the systems of the human organism, including
the
circulatory,
respiratory, skeletal, muscular, digestive, excretory,
reproductive,
integumentary,
nervous, and endocrine
systems
5.1 Physical
and Chemical
Changes in
Digestion
5.3
Circulatory and Respiratory
Systems
5.4
Work/Skeletal and Muscular
Systems
5.5
Maintaining Balance
7.12C Recognize
levels of organization in
plants and animals, including cells, tissues,
organs, organ systems, and organisms
5.6 Levels of Organization
7.12D Differentiate between structure and function in
plant and animal cell organelles,
including cell membrane, cell wall, nucleus, cytoplasm, mitochondrion, chloroplast,
and vacuole
4.2 Plant and Animal Cells
4.1
Cells
7.12E Compare the functions of a cell to the functions of organisms such as waste removal 4.1 Cells
5.6 Levels of Organization
7.12F Recognize
that
according to cell theory all organisms are composed
of cells and
cells carry on
similar functions
such as extracting energy
from
food to sustain life
4.1
Cells
