  Learning objectives in lesson planning serve as clear statements that describe what learners will be able to accomplish by the end of a lesson . They are crucial components of effective lesson planning. Teachers can make learning objectives SMART by following these guidelines: 1. Specific : Clearly define what students are expected to learn. Avoid vague language and ensure the objective is precise and focused. 2. Measurable : Include criteria that allow for assessment of whether students have achieved the objective. This could involve quantifiable measures like scores, percentages, or observable behaviors. 3. Achievable : Ensure that the objective is realistic and attainable within the given context of time, resources, and students' capabilities. 4. Relevant : Connect the objective to the broader goals of the curriculum and ensure its importance and relevance to students' learning needs and interests. 5. Time-bound: Specify a timeframe within which the objective shoul

  It is a system that is related with respiration and consists of all the respiratory organs. What is respiration? Respiration is the process of liberating energy by the process of food oxidation the system gets oxygen for breathing from the environment and also removes carbon dioxide gas in turn. Respiratory organs The human respiratory system typically includes the following organs that help in the exchange of gases. nose pharynx larynx trachea bronchi bronchioles alveoli lungs Nose consists of two nostrils. Each has got the tiny hairs (cilia), mucus membrane, blood capillaries. It not only serves as a sense organ for smelling things but also acts as a passage of air. The tiny hairs filter the air while mucus sticks any solid particle like dust or any other substance however blood capillaries help in warming up the air that is entering inside the other respiratory organs. Pharynx is a part of the throat and serves as a passage for both air and food. There

Sense is a biological way of perceiving things that are happening outside in the environment or within the body. These are detected by the specialised receptor cells lying in different sense organs and then they are transmitted in the form of nerve impulses which travel to brain and then the body becomes able to respond to the specific stimuli. So the question arises here,  What are the different senses that human beings have? Here we'll see five different senses along with their sense organs that receive or detect them. 1. Touch : This is the first sense with which we are blessed. When the babies come in this world then before opening their eyes, first thing they feel is the gentle touch of their mothers which welcomes them in this world. So the biggest sense organ, skin is supplied with multiple sensors within it to detect changes in pressure, temperature, pain, vibration etc. They are then sent to brain which are processed by sensory cortex there, this is how we experience
