VERTEBRATES AND INVERTEBRATES BY: Sir PTjohn S6MT-IIe-f-3 | Determine the distinguishing characteristics of vertebrates and invertebrates Exploring the World of Animals: Distinguishing Vertebrates and Invertebrates for Grade 6 Students   In the fascinating realm of biology, students embark on a journey to understand the diversity of the animal kingdom. One fundamental concept is the distinction between vertebrates and invertebrates, two major groups that encompass a vast array of creatures. Let's delve into the distinguishing characteristics of these groups and unravel the wonders of the animal world!   Understanding Vertebrates: Vertebrates are animals that possess a backbone or spine made of vertebrae. This internal skeletal structure provides support and protection for the delicate spinal cord, a crucial part of the nervous system. Vertebrates are found in various environments, from the depths of the oceans to the highest treetops. Here are some key char...

  THE HUMAN BODY SYSTEMS AND ORGANS By: Sir Pj Miana   In 6th-grade science, students typically learn about various body systems, their functions, and the organs associated with each system. Here's an overview of some of the key body systems, along with their definitions, functions, and the organs they include:   1. Circulatory System: Definition: The circulatory system is a network of blood vessels, the heart, and blood that transports nutrients, oxygen, hormones, and waste products throughout the body.   Organs: - Heart: Pumps blood to circulate throughout the body. - Blood Vessels (arteries, veins, capillaries): Tubes that carry blood to and from the heart. - Blood: Carries oxygen, nutrients, and hormones to cells and removes waste products.   2. Respiratory System: Definition: The respiratory system is responsible for the exchange of gases, primarily oxygen and carbon dioxide, between the body and the environment.   Organs: - Lungs: Main organs for gas ...

MUSCULO-SKELETAL SYSTEM Pj Miana Understanding the Musculoskeletal System   Introduction: - The musculoskeletal system is a complex network of structures that provides support, stability, and movement to the human body. - Comprising bones, muscles, joints, ligaments, and tendons, this system is essential for maintaining posture and facilitating various physical activities.   Components of the Musculoskeletal System:   1. Bones:    - Act as the framework of the body, providing structural support and protection for vital organs.    - Bone marrow inside bones plays a crucial role in blood cell production.   2. Muscles:    - Responsible for movement by contracting and relaxing in response to nerve signals.    - Divided into voluntary (skeletal) muscles and involuntary (smooth and cardiac) muscles.   3. Joints:    - Points where bones meet, allowing for movement and flexibility. ...
