2.b. 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.||CA Science||Grade 5||02. Life Sciences||2. Plants and animals have structures for respiration, digestion, waste disposal, and transport of materials.|||7.c. Communicate the logical connection among hypothesis, science concepts, tests conducted, data collected, and conclusions drawn from the scientific evidence.||CA Science||Grade 7||07. Investigation and Experimentation||7. Scientific progress is made by asking meaningful questions & conducting careful investigations. As a basis for understanding this concept, and to address the content of the other strands, students will develop questions & perform investigations.|||9.f. Apply simple mathematical relationships to determine one quantity given the other two (including speed = distance/time, density = mass/volume, force = pressure x area, volume=area x height).||Grade 8||01. Physical Sciences||9. Investigation and Experimentation||9. Scientific progress is made by asking meaningful questions & conducting careful investigations. As a basis for understanding this concept, and to address the content of the other strands, students should develop questions & perform investigations.|||1.g. Recognize the use and limitations of models and theories as scientific representations of reality.||CA Science||Grade 9-12||05. Investigation and Experimentation||1. Scientific progress is made by asking meaningful questions & conducting careful investigations. As a basis for understanding this concept, & to address the content of the other strands, students should develop questions & perform investigations.|||9.a. How the complementary activity of major body systems provides cells with oxygen and nutrients, and removes toxic waste products such as carbon dioxide.||Grade 9-12||03. Biology/Life Sciences||5. Physiology|| 9. As a result of the coordinated structures and functions of organ systems, the internal environment of the human body remains relatively stable (homeostatic), despite changes in the outside environment.
