FOSS AND CALIFORNIA STANDARDS
The Living Systems Module supports the following Life Sciences
Content Standards for grade 5.*
LS2 Plants and animals have structures for respiration,
digestion, waste disposal, and transport of materials.
As a basis for understanding this concept, students know
LS2a. many multicellular organisms have specialized
structures to support the transport of materials.
LS2b. how blood circulates through the heart chambers, lungs,
and body and how carbon dioxide (CO2) and oxygen
(O2) are exchanged in the lungs and tissues.
LS2c. the sequential steps of digestion and the roles of teeth
and the mouth, esophagus, stomach, small
intestine, large intestine, and colon in the function
of the digestive system.
LS2d. the role of the kidney in removing cellular waste from
blood and converting it into urine, which is stored in the
LS2e. how sugar, water, and minerals are transported in a
LS2f plants use carbon dioxide (CO2) and energy from
sunlight to build molecules of sugar and release oxygen.
LS2g. plant and animal cells break down sugar to obtain
energy, a process resulting in carbon dioxide (CO2) and
