1. Identify the sense organ responsible for the sense of touch:
   • The sense organ responsible for the sense of touch is our skin.
2. Explain the importance of the skin as the sense organ of touch:
   • The skin is crucial as the sense organ of touch because it allows us to feel and interact with the world around us. It helps us detect various sensations, such as warmth, cold, pressure, pain, and texture. This sense of touch is vital for our safety and well-being. For example, if we touch something hot, the skin sends a signal to our brain to move our hand away to prevent burns.
3. Understand how the skin helps us interact with the world:
   • The skin acts as a protective barrier between our bodies and the external environment. It helps us sense our surroundings, whether it’s the softness of a pet’s fur, the smoothness of a stone, or the warmth of the sun. Through the skin’s receptors, we can navigate and interact with the world, keeping us aware of potential dangers and enhancing our sensory experiences.
