lesson Plan version 1.1 activities
1. Sit absolutely still. Observe the movements taking place in your body. You must be blinking your eyes time to time. Observe the movements in your body as you breathe. Write down the movements in your note book. We are able to move a few parts of our body easily in various directions and some, only in one direction. Why we are not able to move some parts at all directions?
2. To show that we can bend or move our body only at those points where the bones meet. Materials required: A wooden scale and string. Method: Ask your friend to tie a wooden scale and your arm together. So that the elbow is at the center. Even if you try hard, you cannot bend your elbow.
Conclusion: A single bone cannot bend. The different bones joined together at the elbow, help the elbow to bend.
3. Move your lower arm up and down gently. Feel the contraction and relaxation of your biceps and triceps muscles. The muscles present in the upper arm help in the contraction of front biceps muscles (become short and thick), and also relaxation of rear triceps muscles (become long and thin). You can feel the muscles on top that go stiff. When the arm is moved downwards, the front muscles relax and the rear muscles contract.
4. Place the middle and index fi ngers of your right hand on the inner side of your left wrist. Can you feel a throbbing movement. Why do you feel the throbbing? This throbbing is called the pulse and it is due to the blood fl owing in the arteries. Count the number of pulse in one minute.
How many pulse beats could you count in one minute? The number of beats per minute is called the Pulse rate. A resting person usually has a pulse rate between 72 to 80 beats per minute.
