Exploring life: Introducing Biology                                  SCIENCE 3rd ESO (2013-14)

1. The Scientific Method – lab practice

Unit 1: Living Matter

1. Life from the global to the microscopic scale.
2. Molecules of life:
• Carbohydrates
• Lipids
• Proteins
• Nucleic Acids
3. Anatomy of the cell – lab practice: model
• Animal
• Vegetal
4. Vital functions of cells:
• Nutrition
• Relation
• Reproduction
5. The human organism: an overview
• Tissue description
• Internal regulation
• Skeleton and Muscles

Unit 2: The Nervous System

1.      The nervous system links sensation to response.

2.      Neurons conduct nerve impulses.

3.      The PNS carries information from and to the CNS.

4.      The CNS integrates nervous information.

5.      Sensory receptors link the environment to the nervous system: study of the sense organs. – lab practice: dissection

Unit 3: The circulatory and respiratory systems

1. The circulatory system: anatomy and physiology.
2. The heart pumps blood throughout the circulatory system.
3. Blood composition.
4. The respiratory system: anatomy and physiology. – lab practice: dissection
5. Cardiovascular diseases and smoking damage the body and shorten life.

Unit 4: Nutrition and Digestion

1.      Nutrition depends on digestion and absorption.

2. Each region of the digestive tube is specialized.
3. A  healthful diet provides both fuel and building materials. – activity: calculation of calorie needs
4. Nutritional disorders damage health.

Unit 5. The body's defense system and the regulation of the internal environment: The endocrine system

1. Infectious diseases are caused by pathogens.
2. The human body has three lines of defense against infections.
3. The immune system recognizes specific invaders.
4. Vaccines stimulate the immune response.
5. Disorders of the immune system are major health problems.
6. Homeostasis depends on mechanisms of regulation.
7. The kidneys function in excretion and water-balance.
8. The liver helps maintain homeostasis
9. Hormones function in growth, development, reproduction and homeostasis.

Unit 6. Reproduction and development

1. Reproductive organs transport and produce gametes
2. Hormones regulate the reproductive systems.
3. Fertilization occurs in the oviduct.
4. Embryonic and fetal development occurs in the uterus.
5. Development is a lifelong process.
6. Maintaining a healthy reproductive system requires knowledge.

Unit 7. Biotechnology ?¿

Unit 8. Rocks and Minerals

1. Mineral matter: An overview.
2. Minerals and their properties.
3. The classification of minerals
4. Rocks: An overview.
5. How are igneous rocks formed?
6. How are sedimentary rocks formed?
7. How do rocks change?
8. How do we use rocks?
