Core Skills Analysis
Science
Student explored the circulatory and respiratory systems, learning that blood is made up of plasma, red cells, white cells, and platelets. He described in his own words how oxygen travels from the lungs into the bloodstream and how carbon dioxide is carried back to be exhaled. Using a worksheet, he examined the physiology of breathing, naming the diaphragm, trachea, and alveoli, and he explained the pathway of air during inhalation and exhalation. Through verbalizing these processes, he demonstrated an understanding of how nutrients and waste gases move through the body.
Tips
To deepen Student's grasp, set up a simple model of the lungs using balloons and straws so he can see how inhalation expands the chest cavity. Follow the model with a kitchen‑science experiment that separates food coloring in water to mimic how plasma carries nutrients. Have him keep a daily “breath log” where he notes his breathing rate during rest and after mild activity, then graph the changes. Finally, invite him to create a comic strip that follows an oxygen molecule’s journey from inhalation to delivery to a muscle cell.
