The chemistry block explored the nature of living substances, especially those that are eaten for nourishment. The course looked at the differences and similarities among carbohydrates, proteins, and fats. The block began with a look at varying types of sugars, including glucose, sucrose, fructose, lactose and artificial sweeteners. The students observed how these substances reacted to water, fire and sulfuric acid. The process of photosynthesis and sugar production in the plant was discussed in depth. Other types of carbohydrates, including starch and cellulose, were also explored and tested. The students learned about the important role protein plays in the development and health of the human body. They learned about the nitrogen cycle and how this important element moves between plants, animals, bacteria, the air and soil. The class then studied about how healthy fats contribute to growth. They discovered the differences among saturated, mono-saturated and polyunsaturated fats and how oil differs from fat. Throughout the block, the students experimented with and tested a wide variety of natural substances. They observed and recorded their findings and tried to see how these substances relate to one another under different circumstances.
