KS3 - Gas Exchange

KS3 Biology - Levels of Organisation

This bundle is a complete topic pack containing all powerpoints, student worksheets, risk assessments, stretch and challenge tasks, and answer sheets for the Biology topic “Levels of Organisation”. It also contains many student-led activities on the powerpoints (particularly designed to make the learning of parts and functions of organs/joints etc... easier, more fun and student-led), plenary activities. There are also interactive slides to demonstrate concepts (e.g. gas exchange) as well as self-completing slides where answers can be clicked and move into the correct place (great for distance learning students and cover lessons). Bundle includes: Lesson 1: Tissues and Organs Lesson 2: Organ Systems Lesson 3: Gas Exchange Lesson 4: Breathing Lesson 5: The Skeleton Lesson 6: Joints Lesson 7: Muscles Lesson Objectives: Lesson 1: Tissues and Organs * Define the terms “tissue” and “organ” * Identify some of the key organs in the human body * Identify some of the key organs in plants * Describe what some key organs do Lesson 2: Organ Systems * Define the term “organ system” * Identify some of the key organ systems in the human body and what they do * Describe the hierarchy of organisation in a multicellular organism Lesson 3: Gas Exchange * Name the key parts of the lungs * Define the process of gas exchange * Describe how parts of the gas exchange system are adapted to their function * Compare inhaled and exhaled air * WS: Read data from pie charts and draw conclusions Lesson 4: Breathing * Describe the physical changes that occur when a person inhales and exhales * Describe a method used to estimate lung volume * WS: Measure lung volume * WS: Correlate and analyse data from a practical experiment to draw conclusions Lesson 5: The Skeleton * Label some of the main bones in the skeleton * Describe the structure of a bone * Describe the functions of the skeletal system Lesson 6: Joints * Name and give examples of the types of joint found in the human body * Describe the role of joints in movement * Label the structure of a joint * Carry out the dissection of a joint Lesson 7: Muscles * Describe what a muscle is and give some examples * Describe how muscles cause movement in the body * Describe how antagonistic muscles control movement at a joint * WS: Investigate the strength of muscles
