3. Explain the functions of the bones based on their location in the body.

The learners are able to:

MATERIALS:

1. Long Bones:

• • Explanation: Long bones are like the beams and pillars in a building. They are longer than they are wide, and they provide support and help you move. Your arms and legs have long bones. Think of them as the strong supports that help you run and reach for things.

2. Short Bones:

• • Explanation: Short bones are like the blocks you might use to build a wall. They are almost as wide as they are long, and they give your body strength and stability. The bones in your wrists and ankles are short bones. They're like the sturdy building blocks that keep you steady.

3. Flat Bones:

• • Explanation: Flat bones are like the roof of a house or a shield. They are flat and strong, and they protect important parts inside. Your skull is made up of flat bones, and they act like a protective helmet for your brain.

4. Irregular Bones:

• • Explanation: Irregular bones are unique, like pieces of a puzzle that don't fit neatly into other categories. They have various shapes and sizes, and they can be found in special places like your spine (vertebrae) or your hips. These bones play important roles in supporting and protecting.

5. Sesamoid Bones:

• • Explanation: Sesamoid bones are like tiny seeds that help things move smoothly. They are small, round bones found near joints, like little pebbles. The patella, or kneecap, is an example of a sesamoid bone. It acts like a small rock, helping your knee bend and straighten easily.

The Bones

The bones function as the framework that supports and protects the various organs in the body. They are a combination of several kinds of tissues and contain blood vessels and nerves. Bones are attached to each other at a joint. There are about 275 bones at birth. As a person grows, many of these bones are fused together; in an adult human, the skeleton is composed of 206 bones.

• Serve as the storehouse for calcium

• Produce blood cells (in the red bone marrow)

ARTS - artistic representation of the bones

The learners can identify the importance of their bones in their body and can identify its type.

• The pupils will bring clay.

• Instruct them to create different types of bones using the clay. They can use toothpicks to represent long bones and plastic straws for short bones.

• Encourage creativity and ask them to consider the shape and size of the bones.
