7th Grade Science
Humble ISD Curriculum
Year-At-A-Glance
Enduring Understandings
What students will learn:
• All living things move, respond, obtain and use
energy, are made up of cells, grow/reproduce,
and have a set life span.
• Living organisms must be able to maintain
balance.
• All organisms are made up of smaller units
called cells. Cell theory states that all cells come
from pre-existing cells. Cells carry on similar
functions such as extracting energy from food to
sustain life.
• Inherited traits are governed by genetic material
found on genes in the chromosomes in the
nucleus. Traits are passed from generation to
generation from parents to offspring.
• Sexual reproduction results in more diverse
offspring while asexual reproduction results in
more uniform offspring.
• Human organ systems have specialized cell and
tissue functions that perform work to maintain
life.
• Compounds that contain carbon are called
organic compounds. All living things are made
up of organic compounds.
• An adaptation is a genetic characteristic, either
physical or behavioral, that allows organisms to
survive and reproduce.
• Natural selection and breeding, acting on
variations of traits within a population, create
biodiversity of life through gradual processes
over many generations.
• Earth has a variety of environmental conditions
that support diverse forms of life.
• The relationships of organisms in the
environment depend on factors in the
environment.
• The Sun is our ultimate source of energy.
Radiant energy is transformed by plants into
chemical energy in the form of glucose, in a
process called photosynthesis.
• Photosynthesis is a chemical reaction that uses
carbon dioxide, water, and solar energy to
produce glucose and oxygen.
• Catastrophic events lead to disruptions in the
natural environment and impact ecosystems.
• Ecological succession is the dynamic and
predictable transition of organisms that make up
a community after a disturbance
• There are different eco-regions in Texas and
each of these regions support a wide range of
ecosystems, soil types and land features.
• Weathering, erosion, and deposition shape the
characteristic soil and topography of each ecoregion of Texas.
• A watershed is an area of land from which water
flows into a larger body of water such as a river,
lake, stream, ocean, or aquifer.
Humble ISD 7th Grade Science
Mission: To foster an environment where students work collaboratively to
expand knowledge in all disciplines of science. To provide students a science
foundation with knowledge and skills that will allow them to be successful in the
high school sciences and scientifically literate citizens.

Year at a Glance
Knowledge and Skills
What student will do in the
classroom and beyond:
• Identify that organic compounds contain
carbon and other elements such as hydrogen,
oxygen, phosphorus, nitrogen, or sulfur.
• Recognize levels of organization in plants and
animals.
• Differentiate between structure and function
in plant and animal cell organelles, including
cell membrane, cell wall, nucleus, cytoplasm,
mitochondrion, chloroplast, and vacuole.
• Recognize that radiant energy from the Sun is
transformed into chemical energy through the
process of photosynthesis.
• 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.
• Define heredity as the passage of genetic
instructions from one generation to the next
generation.
• Compare the results of uniform or diverse
offspring from sexual reproduction or asexual
reproduction.
• Recognize that inherited traits of individuals
are governed in the genetic material found in
the genes within chromosomes in the nucleus.
• Identify the main functions of the systems of
the human organism.
• Distinguish between physical and chemical
changes in matter in the digestive system.
• 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.
• Identify some changes in genetic traits that
have occurred over several generations
through natural selection & selective breeding.
• Describe how biodiversity contributes to the
sustainability of an ecosystem.
• Examine organisms or their structures such
as insects or leaves and use dichotomous
keys for identification.
• Observe and describe how different
environments, support different varieties of
organisms.
• Observe, record, and describe the role of
ecological succession such as in a
microhabitat of a garden with weeds.
• Diagram the flow of energy through living
systems, including food chains, food webs,
and energy pyramids.
• Predict and describe how different types of
catastrophic events impact ecosystems.
• Model the effects of human activity on
groundwater and surface water in a
watershed.
