Living Systems
We will be investigating transport systems in multi-cellular organisms that provide each cell with food, water, gas exchange, and waste. Students will learn about the structures functions, and interactions of the circulatory, respiratory, digestive, and excretory system in humans. They will learn about the vascular system in plants (xylem and phloem), and they will compare that system for moving water, minerals, and sugar to the transport system in humans. They will also be introduced to the chemical process of photosynthesis and how sugar is broken down in cells during cellular respiration. In addition, we will be discussing food in terms of nutrients- fats, carbohydrates, proteins, and water.

FOSS EXPECTS STUDENTS TO
- Learn that the basic unit of life is the cell.
